First PC Build (Part 1)

- by Anthony Trudeau

Originally posted on: http://geekswithblogs.net/tonyt/archive/2014/08/05/157959.aspxA couple of months ago I made the decision to build myself a new computer. The intended use is gaming and for using the last real version of Photoshop. I was motivated by the poor state of console gaming and a simple desire to do something I haven’t done before – build a PC from the ground up. I’ve been using PCs for more than two decades. I’ve replaced a component hear and there, but for the last 10 years or so I’ve only used laptops. Therefore, this article will be written from the perspective of someone familiar with PCs, but completely new at building. I’m not an expert and this is not a definitive guide for building a PC, but I do hope that it encourages you to try it yourself. Component List Research There was a lot of research necessary, because building a PC is completely new to me, and I haven’t kept up with what’s out there. The first thing you want to do is nail down what your goals are. Your goals are going to be driven by what you want to do with your computer and personal choice. Don’t neglect the second one, because if you’re doing this for fun you want to get what you want. In my case, I focused on three things: performance, longevity, and aesthetics. The performance aspect is important for gaming and Photoshop. This will drive what components you get. For example, heavy gaming use is going to drive your choice of graphics card. Longevity is relevant to me, because I don’t want to be changing things out anytime soon for the next hot game. The consequence of performance and longevity is cost. Finally, aesthetics was my next consideration. I could have just built a box, but it wouldn’t have been nearly as fun for me. Aesthetics might not be important to you. They are for me. I also like gadgets and that played into at least one purchase for this build. I used PC Part Picker to put together my component list. I found it invaluable during the process and I’d recommend it to everyone. One caveat is that I wouldn’t trust the compatibility aspects. It does a pretty good job of not steering you wrong, but do your own research. The rest of it isn’t really sexy. I started out with what appealed to me and then I made changes and additions as I dived deep into researching each component and interaction I could find. The resources I used are innumerable. I used reviews, product descriptions, forum posts (praises and problems), et al. to assist me. I also asked friends into gaming what they thought about my component list. And when I got near the end I posted my list to the Reddit /r/buildapc forum. I cannot stress the value of extra sets of eyeballs and first hand experiences. Some of the resources I used: PC Part Picker Tom’s Hardware bit-tech Reddit Purchase PC Part Picker favors certain vendors. You should look at others too. In my case I found their favorites to be the best. My priorities were out-the-door price and shipping time. I knew that once I started getting parts I’d want to start building. Luckily, I timed it well and everything arrived within the span of a few days. Here are my opinions on the vendors I ended up using in alphabetical order. Amazon.com is a good, reliable choice. They have excellent customer service in my experience, and I knew I wouldn’t have trouble with them. However, shipping time is often a problem when you use their free shipping unless you order expensive items (I’ve found items over $100 ship quickly). Ultimately though, price wasn’t always the best and their collection of sales tax in my state turned me off them. I did purchase my case from them. I ordered the mouse as well, but I cancelled after it was stuck four days in a “shipping soon” state. I purchased the mouse locally. Best Buy is not my favorite place to do business. There’s a lot of history with poor, uninterested sales representatives and they used to have a lot of bad anti-consumer policies. That’s a lot better now, but the bad taste is still in my mouth. I ended up purchasing the accessories from them including mouse (locally) and headphones. NCIX is a company that I’ve never heard of before. It popped up as a recommendation for my CPU cooler on PC Part Picker. I didn’t do a lot of research on the company, because their policy on you buying insurance for your orders turned me off. That policy makes it clear to me that the company finds me responsible for the shipment once it leaves their dock. That’s not right, and may run afoul of state laws. Regardless they shipped my CPU cooler quickly and I didn’t have a problem. NewEgg.com is a well known company. I had never done business with them, but I’m glad I did. They shipped quickly and provided good visibility over everything. The prices were also the best in most cases. My main complaint is that they have a lot of exchange only return policies on components. To their credit those policies are listed in the cart underneath each item. The visibility tells me that they’re not playing any shenanigans and made me comfortable dealing with that risk. The vast majority of what I ordered came from them. Coming Next In the next part I’ll tackle my build experience.

Alcatel-Lucent: Enterprise 2.0: The Top 5 Things I would Do Over

- by Kellsey Ruppel

Happy Monday! Does anyone else feel as if the weekend went entirely too quickly? At least for those of us in the United States, we have the 4th of July Holiday next week to look forward to This week on the blog, we are going to focus on "WebCenter by Example" and highlight best practices from customers and partners. I recently came across this article and I think this is a great example of how we can learn from one another when it comes to social collaboration adoption. Do you agree with Jem? What things or best practices have you learned in your organizations? By Jem Janik, Enterprise community manager, Alcatel-Lucent Not so long ago, Engage, the Alcatel-Lucent employee social network and collaboration platform, celebrated its third birthday. With more than 25,000 members actively interacting each month, Engage has been a big enough success that it’s been the subject of external articles, and often those of us who helped launch it will go out and speak about what aspects contributed to that success. Hindsight is still 20/20 and what it takes to successfully launch an enterprise 2.0 community is fairly well-known now. Today I want to tell you what I suspect you really want to know about. As the enterprise community manager for Engage, after three years in, what are the top 5 things I wish we (and I mostly mean me) could do over? #5 Define your analytics solution from the start There is so much to do when you launch a community and initially growing it without complete chaos is quite a task. It doesn’t take too long to get to a point where you want to focus your continued efforts in growing company collaboration. Do people truly talk across regional boundaries or have we shifted siloed conversations to a new platform. Is there one organization that doesn’t interact with another? If you are lucky you’ll have someone in your community team well versed in the world of databases and SQL queries, but it takes time to figure out what backend analytics data actually means. Professional support can be expensive and it may be hard to justify later as it typically has the community manager as the only main customer. Figure out what you think you’ll want to know and how to get it early on. The sooner the better even if it doesn’t seem that critical at the time. #4 Lobbies guide you to the right places One piece of feedback that comes up more and more as we keep growing Engage is it’s hard to find stuff, or new people are not sure where to start. Something we’re doing now is defining some general topic areas of interest to be like “lobbies” into the platform and some common hashtags to go with them. I liken this to walking into a large medical or professional building for the first time. There are hundreds of offices, and you look to a sign in the lobby to get guided to the right place for you. We’re building that sign for members now, but again we missed the boat as the majority of the company has had their initial Engage experience. #3 Clean up, clean up, clean up Knowledge work and folksonomies are messy! The day we opened the doors to Engage I would have said we should keep everything ever created in Engage with an argument that it was a window into our collective knowledge so nothing should go. Well, 6000+ groups and 200,000+ pieces of content later, I’ve changed my mind. As previously mentioned, with too much “stuff” the system can be overwhelming to new members and it makes it harder to get what you’re looking for. Do we need that help document about a tool we no longer have? NO! Do we need that group that had 1 document and 2 discussions in the last two years? NO! Should we only have one group about a given topic instead of 4? YES! Last fall, Engage defined a cleanup process for groups not used for a long time. We also formed a volunteer cleaning army who are extra eyes on the hunt for “stuff” that should be updated, merged, or deleted. It’s better late than never, but in line with what’s becoming a theme I wish these efforts had started earlier. #2 Communications & local community management One of the most important aspects of my job is to make sure people who should be talking to each other are actually doing it. Connecting people to the other people they should know, the groups they should join, a piece of content that shouldn’t be missed. I have worked both inside and outside of communications teams, and they are the best informed people in your company. They know when something big is coming, how it impacts employees, how it fits with strategy, who else knows more, etc. Having communications professionals who are power users can help scale up community management because they are already so well connected. They also need to have the platform skills to pay attention without suffering email overload, how to grab someone’s attention, etc. I wish I’d had figured this out much earlier. If I had I would have groomed more communications colleagues into advocates and power members right at the start. #1 Grooming advocates vs. natural advocates I’ve just alluded to this above already. The very best advocates are those who naturally embrace your platform and automatically start to see new ways to work within it. Those advocates seem to come out of the woodwork naturally since some of them are early adopters. Not surprisingly, our best advocates today are those same people who were willing to come kick the tires when the community was completely empty. Unfortunately, we didn’t get a global spread of those natural advocates. I did ask around when we first launched for other people who might be good candidates, but didn’t push too hard as there were so many other things to get ready. That was a mistake. If I could get a redo I would have formally asked for people to be assigned where there were gaps and groomed them into an advocate. Today as we find new advocates to fill the gaps, people are hesitant as the initial set has three years of practice are ahead of the curve power members; it definitely would have been easier earlier on. As fairly early adopters to corporate scale enterprise collaboration, there hasn’t been a roadmap to follow as we’ve grown Engage, which is part of the fun! It’s clear a lot of issues are more easily tackled the earlier you identify and begin to correct them, and I’ve identified the main five I wish I could redo. In the spirit of collaboration, I hope someone else learns from my mistakes! View the original article by Jem here.

SOA Suite Integration: Part 3: Loading files

- by Anthony Shorten

One of the most common scenarios in SOA Integration is the loading of a file into the product from an external source. In Oracle SOA Suite there is a File Adapter that can process many file types into your BPEL process. For this example I will use the File Adapter to load a file of user and emails to update the user object within the Oracle Utilities Application Framework. Remember you can repeat this process with other objects and other file types. Again I am illustrating the ease of integration. The first thing is to create an empty BPEL process that will hold our flow. In Oracle JDeveloper this can be achieved by specifying the Define Service Later template (as other templates have predefined inputs and outputs and in this case we want to specify those). So I will create simpleFileLoad process to house our process. You will start with an empty canvas so you need to first specify the load part of the process using the File Adapter. Select the File Adapter from the Component Palette under BPEL Services and drag and drop it to the left side Partner Links (left is input). You name the Service. In this case I chose LoadFile. Press Next. We will define the interface as part of the wizard so select Define from operation and schema (specified later). Press Next. We are going to choose Read File to denote that we will read the file and specify the default Operation Name as Read. Press Next. The next step is to tell the Adapter the location of the files, how to process them and what to do with them after they have been processed. I am using hardcoded locations in this example but you can have logical locations as well. Press Next. I am now going to tell the adapter how to recognize the files I want to load. In my case I am using CSV files and more importantly I am tell the adapter to run the process for each record in the file it encounters. Press Next. Now, I tell the adapter how often I want to poll for the files. I have taken the defaults. Press Next. At this stage I have no explanation of the format of the input. So I am going to invoke the Native Format Wizard which will guide me through the process of creating the file input format. Clicking the purple cog icon will start the wizard. After an introduction screen (not shown), you specify the format of the input file. The File Adapter supports multiple format types. For this example, I will use Delimited as I am going to load a CSV file. Press Next. The best way for the wizard to work is with a sample. I have a sample file and the wizard will ask how much of the file to use as a template. I will use the defaults. Note: If you are using a language that has other languages other than US-ASCII, it is at this point you specify the character set to use. Press Next. The sample contains multiple instances of a single record type. The wizard supports complex types as well. We will use the appropriate setting for our file. Press Next. You have to specify the file element and the record element. This will be used by the input wizard to translate the CSV data into an XML structure (this will make sense later). I am using LoadUsers as my file delimiter (root element) and User Record as my record root element. Press Next. As the file is CSV the delimiter is "," so I will also specify that the End Of Line (EOL) indicator indicates the end of a record. Press Next. Up until this point your have not given the columns their names. In my case my sample includes the column names in the first record. This is not always the case but you can specify the names and formats of columns in this dialog (not shown). Press Next. The wizard now generates the schema for the input file. You can specify a name for the schema. I have used userupdate.xsd. We want to verify the schema so press Test. You can test the schema by specifying an input sample. and pressing the green play button. You will see the delimiters you specified earlier for the file and the records. Press Ok to continue. A confirmation screen will be displayed showing you the location of the schema in your project. Press Finish to return to the File Adapter configuration. You will now see the schema and elements prepopulated from the wizard. Press Next. The File Adapter configuration is now complete. Press Finish. Now you need to receive the input from the LoadFile component so we need to place a Receive node in the BPEL process by drag and dropping the Receive component from the Component Palette under BPEL Constructs onto the BPEL process. We link the receive process with the LoadFile component by dragging the left most connect node of the Receive node to the LoadFile component. Once the link is established you need to name the Receive node appropriately and as in the post of the last part of this series you need to generate input variables for the BPEL process to hold the input records in. You need to now add the product Web Service. The process is the same as described in the post of the last part of this series. You drop the Web Service BPEL Service onto the right side of the process and fill in the details of the WSDL URL . You also have to add an Invoke node to call the service and generate the input and outputs variables for the call in the Invoke node. Now, to get the inputs from File to the service. You have to use a Transform (you can use an Assign action but a Transform action is more flexible). You drag and drop the Transform component from the Component Palette under Oracle Extensions and place it between the Receive and Invoke nodes. We name the Transform Node, Mapper File and associate the source of the mapping the schema from the Receive node and the output will be the input variable from the Invoke node. We now build the transform. We first map the user and email attributes by drag and drop the elements from the left to the right. The reason we needed to use the transform is that we will be telling the AS-User service that we want to issue an update action. Remember when we registered the service we actually used Read as the default. If we do not otherwise inform the service to use the Update action it will use the Read action instead (which is not desired). To specify the update action you need to click on the transactionType node on the right and select Set Text to set the action. You need to specify the transactionType of UPD (for update). The mapping is now complete. The final BPEL process is ready for deployment. You then deploy the BPEL process to the server and to test the service by simply dropping a file, in the same pattern/name as you specified, in the directory you specified in the File Adapter. You will see each record as a separate instance entry in the Fusion Middleware Control console. You can now load files into the product. You can repeat this process for each type of file to process. While this was a simple example it illustrates the method of loading data can be achieved using SOA Suite in conjunction with our products.

Secure Your Wireless Router: 8 Things You Can Do Right Now

- by Chris Hoffman

A security researcher recently discovered a backdoor in many D-Link routers, allowing anyone to access the router without knowing the username or password. This isn’t the first router security issue and won’t be the last. To protect yourself, you should ensure that your router is configured securely. This is about more than just enabling Wi-Fi encryption and not hosting an open Wi-Fi network. Disable Remote Access Routers offer a web interface, allowing you to configure them through a browser. The router runs a web server and makes this web page available when you’re on the router’s local network. However, most routers offer a “remote access” feature that allows you to access this web interface from anywhere in the world. Even if you set a username and password, if you have a D-Link router affected by this vulnerability, anyone would be able to log in without any credentials. If you have remote access disabled, you’d be safe from people remotely accessing your router and tampering with it. To do this, open your router’s web interface and look for the “Remote Access,” “Remote Administration,” or “Remote Management” feature. Ensure it’s disabled — it should be disabled by default on most routers, but it’s good to check. Update the Firmware Like our operating systems, web browsers, and every other piece of software we use, router software isn’t perfect. The router’s firmware — essentially the software running on the router — may have security flaws. Router manufacturers may release firmware updates that fix such security holes, although they quickly discontinue support for most routers and move on to the next models. Unfortunately, most routers don’t have an auto-update feature like Windows and our web browsers do — you have to check your router manufacturer’s website for a firmware update and install it manually via the router’s web interface. Check to be sure your router has the latest available firmware installed. Change Default Login Credentials Many routers have default login credentials that are fairly obvious, such as the password “admin”. If someone gained access to your router’s web interface through some sort of vulnerability or just by logging onto your Wi-Fi network, it would be easy to log in and tamper with the router’s settings. To avoid this, change the router’s password to a non-default password that an attacker couldn’t easily guess. Some routers even allow you to change the username you use to log into your router. Lock Down Wi-Fi Access If someone gains access to your Wi-Fi network, they could attempt to tamper with your router — or just do other bad things like snoop on your local file shares or use your connection to downloaded copyrighted content and get you in trouble. Running an open Wi-Fi network can be dangerous. To prevent this, ensure your router’s Wi-Fi is secure. This is pretty simple: Set it to use WPA2 encryption and use a reasonably secure passphrase. Don’t use the weaker WEP encryption or set an obvious passphrase like “password”. Disable UPnP A variety of UPnP flaws have been found in consumer routers. Tens of millions of consumer routers respond to UPnP requests from the Internet, allowing attackers on the Internet to remotely configure your router. Flash applets in your browser could use UPnP to open ports, making your computer more vulnerable. UPnP is fairly insecure for a variety of reasons. To avoid UPnP-based problems, disable UPnP on your router via its web interface. If you use software that needs ports forwarded — such as a BitTorrent client, game server, or communications program — you’ll have to forward ports on your router without relying on UPnP. Log Out of the Router’s Web Interface When You’re Done Configuring It Cross site scripting (XSS) flaws have been found in some routers. A router with such an XSS flaw could be controlled by a malicious web page, allowing the web page to configure settings while you’re logged in. If your router is using its default username and password, it would be easy for the malicious web page to gain access. Even if you changed your router’s password, it would be theoretically possible for a website to use your logged-in session to access your router and modify its settings. To prevent this, just log out of your router when you’re done configuring it — if you can’t do that, you may want to clear your browser cookies. This isn’t something to be too paranoid about, but logging out of your router when you’re done using it is a quick and easy thing to do. Change the Router’s Local IP Address If you’re really paranoid, you may be able to change your router’s local IP address. For example, if its default address is 192.168.0.1, you could change it to 192.168.0.150. If the router itself were vulnerable and some sort of malicious script in your web browser attempted to exploit a cross site scripting vulnerability, accessing known-vulnerable routers at their local IP address and tampering with them, the attack would fail. This step isn’t completely necessary, especially since it wouldn’t protect against local attackers — if someone were on your network or software was running on your PC, they’d be able to determine your router’s IP address and connect to it. Install Third-Party Firmwares If you’re really worried about security, you could also install a third-party firmware such as DD-WRT or OpenWRT. You won’t find obscure back doors added by the router’s manufacturer in these alternative firmwares. Consumer routers are shaping up to be a perfect storm of security problems — they’re not automatically updated with new security patches, they’re connected directly to the Internet, manufacturers quickly stop supporting them, and many consumer routers seem to be full of bad code that leads to UPnP exploits and easy-to-exploit backdoors. It’s smart to take some basic precautions. Image Credit: Nuscreen on Flickr

Online ALTER TABLE in MySQL 5.6

- by Marko Mäkelä

This is the low-level view of data dictionary language (DDL) operations in the InnoDB storage engine in MySQL 5.6. John Russell gave a more high-level view in his blog post April 2012 Labs Release – Online DDL Improvements. MySQL before the InnoDB Plugin Traditionally, the MySQL storage engine interface has taken a minimalistic approach to data definition language. The only natively supported operations were CREATE TABLE, DROP TABLE and RENAME TABLE. Consider the following example: CREATE TABLE t(a INT); INSERT INTO t VALUES (1),(2),(3); CREATE INDEX a ON t(a); DROP TABLE t; The CREATE INDEX statement would be executed roughly as follows: CREATE TABLE temp(a INT, INDEX(a)); INSERT INTO temp SELECT * FROM t; RENAME TABLE t TO temp2; RENAME TABLE temp TO t; DROP TABLE temp2; You could imagine that the database could crash when copying all rows from the original table to the new one. For example, it could run out of file space. Then, on restart, InnoDB would roll back the huge INSERT transaction. To fix things a little, a hack was added to ha_innobase::write_row for committing the transaction every 10,000 rows. Still, it was frustrating that even a simple DROP INDEX would make the table unavailable for modifications for a long time. Fast Index Creation in the InnoDB Plugin of MySQL 5.1 MySQL 5.1 introduced a new interface for CREATE INDEX and DROP INDEX. The old table-copying approach can still be forced by SET old_alter_table=0. This interface is used in MySQL 5.5 and in the InnoDB Plugin for MySQL 5.1. Apart from the ability to do a quick DROP INDEX, the main advantage is that InnoDB will execute a merge-sort algorithm before inserting the index records into each index that is being created. This should speed up the insert into the secondary index B-trees and potentially result in a better B-tree fill factor. The 5.1 ALTER TABLE interface was not perfect. For example, DROP FOREIGN KEY still invoked the table copy. Renaming columns could conflict with InnoDB foreign key constraints. Combining ADD KEY and DROP KEY in ALTER TABLE was problematic and not atomic inside the storage engine. The ALTER TABLE interface in MySQL 5.6 The ALTER TABLE storage engine interface was completely rewritten in MySQL 5.6. Instead of introducing a method call for every conceivable operation, MySQL 5.6 introduced a handful of methods, and data structures that keep track of the requested changes. In MySQL 5.6, online ALTER TABLE operation can be requested by specifying LOCK=NONE. Also LOCK=SHARED and LOCK=EXCLUSIVE are available. The old-style table copying can be requested by ALGORITHM=COPY. That one will require at least LOCK=SHARED. From the InnoDB point of view, anything that is possible with LOCK=EXCLUSIVE is also possible with LOCK=SHARED. Most ALGORITHM=INPLACE operations inside InnoDB can be executed online (LOCK=NONE). InnoDB will always require an exclusive table lock in two phases of the operation. The execution phases are tied to a number of methods: handler::check_if_supported_inplace_alter Checks if the storage engine can perform all requested operations, and if so, what kind of locking is needed. handler::prepare_inplace_alter_table InnoDB uses this method to set up the data dictionary cache for upcoming CREATE INDEX operation. We need stubs for the new indexes, so that we can keep track of changes to the table during online index creation. Also, crash recovery would drop any indexes that were incomplete at the time of the crash. handler::inplace_alter_table In InnoDB, this method is used for creating secondary indexes or for rebuilding the table. This is the ‘main’ phase that can be executed online (with concurrent writes to the table). handler::commit_inplace_alter_table This is where the operation is committed or rolled back. Here, InnoDB would drop any indexes, rename any columns, drop or add foreign keys, and finalize a table rebuild or index creation. It would also discard any logs that were set up for online index creation or table rebuild. The prepare and commit phases require an exclusive lock, blocking all access to the table. If MySQL times out while upgrading the table meta-data lock for the commit phase, it will roll back the ALTER TABLE operation. In MySQL 5.6, data definition language operations are still not fully atomic, because the data dictionary is split. Part of it is inside InnoDB data dictionary tables. Part of the information is only available in the *.frm file, which is not covered by any crash recovery log. But, there is a single commit phase inside the storage engine. Online Secondary Index Creation It may occur that an index needs to be created on a new column to speed up queries. But, it may be unacceptable to block modifications on the table while creating the index. It turns out that it is conceptually not so hard to support online index creation. All we need is some more execution phases: Set up a stub for the index, for logging changes. Scan the table for index records. Sort the index records. Bulk load the index records. Apply the logged changes. Replace the stub with the actual index. Threads that modify the table will log the operations to the logs of each index that is being created. Errors, such as log overflow or uniqueness violations, will only be flagged by the ALTER TABLE thread. The log is conceptually similar to the InnoDB change buffer. The bulk load of index records will bypass record locking. We still generate redo log for writing the index pages. It would suffice to log page allocations only, and to flush the index pages from the buffer pool to the file system upon completion. Native ALTER TABLE Starting with MySQL 5.6, InnoDB supports most ALTER TABLE operations natively. The notable exceptions are changes to the column type, ADD FOREIGN KEY except when foreign_key_checks=0, and changes to tables that contain FULLTEXT indexes. The keyword ALGORITHM=INPLACE is somewhat misleading, because certain operations cannot be performed in-place. For example, changing the ROW_FORMAT of a table requires a rebuild. Online operation (LOCK=NONE) is not allowed in the following cases: when adding an AUTO_INCREMENT column, when the table contains FULLTEXT indexes or a hidden FTS_DOC_ID column, or when there are FOREIGN KEY constraints referring to the table, with ON…CASCADE or ON…SET NULL option. The FOREIGN KEY limitations are needed, because MySQL does not acquire meta-data locks on the child or parent tables when executing SQL statements. Theoretically, InnoDB could support operations like ADD COLUMN and DROP COLUMN in-place, by lazily converting the table to a newer format. This would require that the data dictionary keep multiple versions of the table definition. For simplicity, we will copy the entire table, even for DROP COLUMN. The bulk copying of the table will bypass record locking and undo logging. For facilitating online operation, a temporary log will be associated with the clustered index of table. Threads that modify the table will also write the changes to the log. When altering the table, we skip all records that have been marked for deletion. In this way, we can simply discard any undo log records that were not yet purged from the original table. Off-page columns, or BLOBs, are an important consideration. We suspend the purge of delete-marked records if it would free any off-page columns from the old table. This is because the BLOBs can be needed when applying changes from the log. We have special logging for handling the ROLLBACK of an INSERT that inserted new off-page columns. This is because the columns will be freed at rollback.

REST to Objects in C#

RESTful interfaces for web services are all the rage for many Web 2.0 sites. If you want to consume these in a very simple fashion, LINQ to XML can do the job pretty easily in C#. If you go searching for help on this, youll find a lot of incomplete solutions and fairly large toolkits and frameworks (guess how I know this) this quick article is meant to be a no fluff just stuff approach to making this work. POCO Objects Lets assume you have a Model that you want to suck data into from a RESTful web service. Ideally this is a Plain Old CLR Object, meaning it isnt infected with any persistence or serialization goop. It might look something like this: public class Entry { public int Id; public int UserId; public DateTime Date; public float Hours; public string Notes; public bool Billable; public override string ToString() { return String.Format("[{0}] User: {1} Date: {2} Hours: {3} Notes: {4} Billable {5}", Id, UserId, Date, Hours, Notes, Billable); } } Not that this isnt a completely trivial object. Lets look at the API for the service. RESTful HTTP Service In this case, its TickSpots API, with the following sample output: <?xml version="1.0" encoding="UTF-8"?> <entries type="array"> <entry> <id type="integer">24</id> <task_id type="integer">14</task_id> <user_id type="integer">3</user_id> <date type="date">2008-03-08</date> <hours type="float">1.00</hours> <notes>Had trouble with tribbles.</notes> <billable>true</billable> # Billable is an attribute inherited from the task <billed>true</billed> # Billed is an attribute to track whether the entry has been invoiced <created_at type="datetime">Tue, 07 Oct 2008 14:46:16 -0400</created_at> <updated_at type="datetime">Tue, 07 Oct 2008 14:46:16 -0400</updated_at> # The following attributes are derived and provided for informational purposes: <user_email>[email protected]</user_email> <task_name>Remove converter assembly</task_name> <sum_hours type="float">2.00</sum_hours> <budget type="float">10.00</budget> <project_name>Realign dilithium crystals</project_name> <client_name>Starfleet Command</client_name> </entry> </entries> Im assuming in this case that I dont necessarily care about all of the data fields the service is returning I just need some of them for my applications purposes. Thus, you can see there are more elements in the <entry> XML than I have in my Entry class. Get The XML with C# The next step is to get the XML. The following snippet does the heavy lifting once you pass it the appropriate URL: protected XElement GetResponse(string uri) { var request = WebRequest.Create(uri) as HttpWebRequest; request.UserAgent = ".NET Sample"; request.KeepAlive = false; request.Timeout = 15 * 1000; var response = request.GetResponse() as HttpWebResponse; if (request.HaveResponse == true && response != null) { var reader = new StreamReader(response.GetResponseStream()); return XElement.Parse(reader.ReadToEnd()); } throw new Exception("Error fetching data."); } This is adapted from the Yahoo Developer article on Web Service REST calls. Once you have the XML, the last step is to get the data back as your POCO. Use LINQ-To-XML to Deserialize POCOs from XML This is done via the following code: public IEnumerable<Entry> List(DateTime startDate, DateTime endDate) { string additionalParameters = String.Format("start_date={0}&end_date={1}", startDate.ToShortDateString(), endDate.ToShortDateString()); string uri = BuildUrl("entries", additionalParameters); XElement elements = GetResponse(uri); var entries = from e in elements.Elements() where e.Name.LocalName == "entry" select new Entry { Id = int.Parse(e.Element("id").Value), UserId = int.Parse(e.Element("user_id").Value), Date = DateTime.Parse(e.Element("date").Value), Hours = float.Parse(e.Element("hours").Value), Notes = e.Element("notes").Value, Billable = bool.Parse(e.Element("billable").Value) }; return entries; } For completeness, heres the BuildUrl method for my TickSpot API wrapper: // Change these to your settings protected const string projectDomain = "DOMAIN.tickspot.com"; private const string authParams = "[email protected]&password=MyTickSpotPassword"; protected string BuildUrl(string apiMethod, string additionalParams) { if (projectDomain.Contains("DOMAIN")) { throw new ApplicationException("You must update your domain in ProjectRepository.cs."); } if (authParams.Contains("MyTickSpotPassword")) { throw new ApplicationException("You must update your email and password in ProjectRepository.cs."); } return string.Format("https://{0}/api/{1}?{2}&{3}", projectDomain, apiMethod, authParams, additionalParams); } Thats it! Now go forth and consume XML and map it to classes you actually want to work with. Have fun! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

Oracle Certification and virtualization Solutions.

- by scoter

As stated in official MOS ( My Oracle Support ) document 249212.1 support for Oracle products on non-Oracle VM platforms follow exactly the same stance as support for VMware and, so, the only x86 virtualization software solution certified for any Oracle product is "Oracle VM". Based on the fact that: Oracle VM is totally free ( you have the option to buy Oracle-Support ) Certified is pretty different from supported ( OracleVM is certified, others could be supported ) With Oracle VM you may not require to reproduce your issue(s) on physical server Oracle VM is the only x86 software solution that allows hard-partitioning *** *** see details to these Oracle public links: http://www.oracle.com/technetwork/server-storage/vm/ovm-hardpart-168217.pdf http://www.oracle.com/us/corporate/pricing/partitioning-070609.pdf people started asking to migrate from third party virtualization software (ex. RH KVM, VMWare) to Oracle VM. Migrating RH KVM guest to Oracle VM. OracleVM has a built-in P2V utility ( Official Documentation ) but in some cases we can't use it, due to : network inaccessibility between hypervisors ( KVM and OVM ) network slowness between hypervisors (KVM and OVM) size of the guest virtual-disks Here you'll find a step-by-step guide to "manually" migrate a guest machine from KVM to OVM. 1. Verify source guest characteristics. Using KVM web console you can verify characteristics of the guest you need to migrate, such as: CPU Cores details Defined Memory ( RAM ) Name of your guest Guest operating system Disks details ( number and size ) Network details ( number of NICs and network configuration ) 2. Export your guest in OVF / OVA format. The export from Redhat KVM ( kernel virtual machine ) will create a structured export of your guest: [root@ovmserver1 mnt]# lltotal 12drwxrwx--- 5 36 36 4096 Oct 19 2012 b8296fca-13c4-4841-a50f-773b5139fcee b8296fca-13c4-4841-a50f-773b5139fcee is the ID of the guest exported from RH-KVM [root@ovmserver1 mnt]# cd b8296fca-13c4-4841-a50f-773b5139fcee/[root@ovmserver1 b8296fca-13c4-4841-a50f-773b5139fcee]# ls -ltrtotal 12drwxr-x--- 4 36 36 4096 Oct 19 2012 masterdrwxrwx--- 2 36 36 4096 Oct 29 2012 dom_mddrwxrwx--- 4 36 36 4096 Oct 31 2012 images images contains your virtual-disks exported [root@ovmserver1 b8296fca-13c4-4841-a50f-773b5139fcee]# cd images/[root@ovmserver1 images]# ls -ltratotal 16drwxrwx--- 5 36 36 4096 Oct 19 2012 ..drwxrwx--- 2 36 36 4096 Oct 31 2012 d4ef928d-6dc6-4743-b20d-568b424728a5drwxrwx--- 2 36 36 4096 Oct 31 2012 4b241ea0-43aa-4f3b-ab7d-2fc633b491a1drwxrwx--- 4 36 36 4096 Oct 31 2012 .[root@ovmserver1 images]# cd d4ef928d-6dc6-4743-b20d-568b424728a5/[root@ovmserver1 d4ef928d-6dc6-4743-b20d-568b424728a5]# ls -ltotal 5169092-rwxr----- 1 36 36 187904819200 Oct 31 2012 4c03b1cf-67cc-4af0-ad1e-529fd665dac1-rw-rw---- 1 36 36 341 Oct 31 2012 4c03b1cf-67cc-4af0-ad1e-529fd665dac1.meta[root@ovmserver1 d4ef928d-6dc6-4743-b20d-568b424728a5]# file 4c03b1cf-67cc-4af0-ad1e-529fd665dac14c03b1cf-67cc-4af0-ad1e-529fd665dac1: LVM2 (Linux Logical Volume Manager) , UUID: sZL1Ttpy0vNqykaPahEo3hK3lGhwspv 4c03b1cf-67cc-4af0-ad1e-529fd665dac1 is the first exported disk ( physical volume ) [root@ovmserver1 d4ef928d-6dc6-4743-b20d-568b424728a5]# cd ../4b241ea0-43aa-4f3b-ab7d-2fc633b491a1/[root@ovmserver1 4b241ea0-43aa-4f3b-ab7d-2fc633b491a1]# ls -ltotal 5568076-rwxr----- 1 36 36 107374182400 Oct 31 2012 9020f2e1-7b8a-4641-8f80-749768cc237a-rw-rw---- 1 36 36 341 Oct 31 2012 9020f2e1-7b8a-4641-8f80-749768cc237a.meta[root@ovmserver1 4b241ea0-43aa-4f3b-ab7d-2fc633b491a1]# file 9020f2e1-7b8a-4641-8f80-749768cc237a9020f2e1-7b8a-4641-8f80-749768cc237a: x86 boot sector; partition 1: ID=0x83, active, starthead 1, startsector 63, 401562 sectors; partition 2: ID=0x82, starthead 0, startsector 401625, 65529135 sectors; startsector 63, 401562 sectors; partition 2: ID=0x82, starthead 0, startsector 401625, 65529135 sectors; partition 3: ID=0x83, starthead 254, startsector 65930760, 8385930 sectors; partition 4: ID=0x5, starthead 254, startsector 74316690, 135395820 sectors, code offset 0x48 9020f2e1-7b8a-4641-8f80-749768cc237a is the second exported disk, with partition 1 bootable 3.

Copy KVM exported virtual-disks to OVM virtual-disks. Keeping your Oracle VM guest stopped you can copy KVM exported virtual-disks to OVM virtual-disks; what I did is only to locally mount the filesystem containing the exported virtual-disk ( by an usb device ) on my OVS; the copy automatically resize OVM virtual-disks ( previously created with a size of 1GB ) . nohup cp /mnt/b8296fca-13c4-4841-a50f-773b5139fcee/images/4b241ea0-43aa-4f3b-ab7d-2fc633b491a1/9020f2e1-7b8a-4641-8f80-749768cc237a /OVS/Repositories/0004fb00000300004f17b7368139eb41/VirtualDisks/0004fb000012000097c1bfea9834b17d.img & nohup cp /mnt/b8296fca-13c4-4841-a50f-773b5139fcee/images/d4ef928d-6dc6-4743-b20d-568b424728a5/4c03b1cf-67cc-4af0-ad1e-529fd665dac1 /OVS/Repositories/0004fb00000300004f17b7368139eb41/VirtualDisks/0004fb0000120000cde6a11c3cb1d0be.img & 7. When copy completed refresh repository to aknowledge the new-disks size. 7. After "refresh repository" is completed, start guest machine by Oracle VM manager. After the first start of your guest: - verify that you can see all disks and partitions - verify that your guest is network reachable ( MAC Address of your NICs changed ) Eventually you can also evaluate to convert your guest to PVM ( Paravirtualized virtual Machine ) following official Oracle documentation. Ciao Simon COTER ps: next-time I'd like to post an article reporting how to manually migrate Virtual-Iron guests to OracleVM. Comments and corrections are welcome.

Webcast Q&A: ING on How to Scale Role Management and Compliance

- by Tanu Sood

Thanks to all who attended the live webcast we hosted on ING: Scaling Role Management and Access Certifications to Thousands of Applications on Wed, April 11th. Those of you who couldn’t join us, the webcast replay is now available. Many thanks to our guest speaker, Mark Robison, Enterprise Architect at ING for walking us through ING’s drivers and rationale for the platform approach, the phased implementation strategy, results & metrics, roadmap and recommendations. We greatly appreciate the insight he shared with us all on the deployment synergies between Oracle Identity Manager (OIM) and Oracle Identity Analytics (OIA) to enforce streamlined user and role management and scalable compliance. Mark was also kind enough to walk us through specific solutions features that helped ING manage the problem of role explosion and implement closed loop remediation. Our host speaker, Neil Gandhi, Principal Product Manager, Oracle rounded off the presentation by discussing common use cases and deployment scenarios we see organizations implement to automate user/identity administration and enforce closed-loop scalable compliance. Neil also called out the specific features in Oracle Identity Analytics 11gR1 that cater to expediting and streamlining compliance processes such as access certifications. While we tackled a few questions during the webcast, we have captured the responses to those that we weren’t able to get to here; our sincere thanks to Mark Robison for taking the time to respond to questions specific to ING’s implementation and strategy. Q. Did you include business friendly entitlment descriptions, or is the business seeing application descriptors A. We include very business friendly descriptions. The OIA tool has the facility to allow this. Q. When doing attestation on job change, who is in the workflow to review and confirm that the employee should continue to have access? Is that a best practice? A. The new and old manager are in the workflow. The tool can check for any Separation of Duties (SOD) violations with both having similiar accesses. It may not be a best practice, but it is a reality of doing your old and new job for a transition period on a transfer. Q. What versions of OIM and OIA are being used at ING? A. OIM 11gR1 and OIA 11gR1; the very latest versions available. Q. Are you using an entitlements / role catalog? A. Yes. We use both roles and entitlements. Q. What specific unexpected benefits did the Identity Warehouse provide ING? A. The most unanticipated was to help Legal Hold identify user ID's in the various applications. Other benefits included providing a one stop shop for all aggregated ID information. Q. How fine grained are your application and entitlements? Did OIA, OIM support that level of granularity? A. We have some very fine grained entitlements, but we role this up into approved Roles to allow for easier management. For managing very fine grained entitlements, Oracle offers the Oracle Entitlement Server. We currently do not own this software but are considering it. Q. Do you allow any individual access or is everything truly role based? A. We are a hybrid environment with roles and individual positive and negative entitlements Q. Did you use an Agile methodology like scrum to deliver functionality during your project? A. We started with waterfall, but used an agile approach to provide benefits after the initial implementation Q. How did you handle rolling out the standard ID format to existing users? A. We just used the standard IDs for new users. We have not taken on a project to address the existing nonstandard IDs. Q. To avoid role explosion, how do you deal with apps that require more than a couple of entitlement TYPES? For example, an app may have different levels of access and it may need to know the user's country/state to associate them with particular customers. A. We focus on the functional user and craft the role around their daily job requirements. The role captures the required application entitlements. To keep role explosion down, we use role mining in OIA and also meet and interview the business. It is an iterative process to get role consensus. Q. Great presentation! How many rounds of Certifications has ING performed so far? A. Around 7 quarters and constant certifications on transfer. Q. Did you have executive support from the top down A. Yes The executive support was key to our success. Q. For your cloud instance are you using OIA or OIM as SaaS? A. No. We are just provisioning and deprovisioning to various Cloud providers. (Service Now is an example) Q. How do you ensure a role owner does not get more priviliges as are intended and thus violates another role, e,g, a DBA Roles should not get tor rigt to run somethings as root, as this would affect the root role? A. We have SOD checks. Also all Roles are initially approved by external audit and the role owners have to certify the roles and any changes Q. What is your ratio of employees to roles? A. We are still in process going through our various lines of business, so I do not have a final ratio. From what we have seen, the ratio varies greatly depending on the Line of Business and the diversity of Job Functions. For standardized lines of business such as call centers, the ratio is very good where we can have a single role that covers many employees. For specialized lines of business like treasury, it can be one or two people per role. Q. Is ING using Oracle On Demand service ? A. No Q. Do you have to implement or migrate to OIM in order to get the Identity Warehouse, or can OIA provide the identity warehouse as well if you haven't reached OIM yet? A. No, OIM deployment is not required to implement OIA’s Identity Warehouse but as you heard during the webcast, there are tremendous deployment synergies in deploying both OIA and OIM together. Q. When is the Security Governor product coming out? A. Oracle Security Governor for Healthcare is available today. Hope you enjoyed the webcast and we look forward to having you join us for the next webcast in the Customers Talk: Identity as a Platform webcast series: Toyota: Putting Customers First – Identity Platform as a Business Enabler Wednesday, May 16th at 10 am PST/ 1 pm EST Register Today You can also register for a live event at a city near you where Aberdeen’s Derek Brink will discuss the survey results from the recently published report “Analyzing Platform vs. Point Solution Approach in Identity”. And, you can do a quick (& free) online assessment of your identity programs by benchmarking it against the 160 organizations surveyed in the Aberdeen report, compliments of Oracle.

Resolving data redundancy up front

- by okeofs

Introduction As all of us do when confronted with a problem, the resource of choice is to ‘Google it’. This is where the plot thickens. Recently I was asked to stage data from numerous databases which were to be loaded into a data warehouse. To make a long story short, I was looking for a manner in which to obtain the table names from each database, to ascertain potential overlap. As the source data comes from a SQL database created from dumps of a third party product, one could say that there were +/- 95 tables for each database. Yes I know that first instinct is to use the system stored procedure “exec sp_msforeachdb 'select "?" AS db, * from [?].sys.tables'”. However, if one stops to think about this, it would be nice to have all the results in a temporary or disc based table; which in itself , implies additional labour. This said, I decided to ‘re-invent’ the wheel. The full code sample may be found at the bottom of this article. Define a few temporary tables and variables declare @SQL varchar(max); declare @databasename varchar(75) /* drop table ##rawdata3 drop table #rawdata1 drop table #rawdata11 */ -- A temp table to hold the names of my databases CREATE TABLE #rawdata1 ( database_name varchar(50) , database_size varchar(50), remarks Varchar(50) ) --A temp table with the same database names as above, HOWEVER using an --Identity number (recNO) as a loop variable. --You will note below that I loop through until I reach 25 (see below) as at --that point the system databases, the reporting server database etc begin. --1- 24 are user databases. These are really what I was looking for. --Whilst NOT the best solution,it works and the code was meant as a quick --and dirty. CREATE TABLE #rawdata11 ( recNo int identity(1,1), database_name varchar(50) , database_size varchar(50), remarks Varchar(50) ) --My output table showing the database name and table name CREATE TABLE ##rawdata3 ( database_name varchar(75) , table_name varchar(75), ) Insert the database names into a temporary table I pull the database names using the system stored procedure sp_databases INSERT INTO #rawdata1 EXEC sp_databases Go Insert the results from #rawdata1 into a table containing a record number #rawdata11 so that I can LOOP through the extract INSERT into #rawdata11 select * from #rawdata1 We now declare 3 more variables: @kounter is used to keep track of our position within the loop. @databasename is used to keep track of the’ current ‘ database name being used in the current pass of the loop; as inorder to obtain the tables for that database we need to issue a ‘USE’ statement, an insert command and other related code parts. This is the challenging part. @sql is a varchar(max) variable used to contain the ‘USE’ statement PLUS the’ insert ‘ code statements. We now initalize @kounter to 1 . declare @kounter int; declare @databasename varchar(75); declare @sql varchar(max); set @kounter = 1 The Loop The astute reader will remember that the temporary table #rawdata11 contains our database names and each ‘database row’ has a record number (recNo). I am only interested in record numbers under 25. I now set the value of the temporary variable @DatabaseName (see below) .Note that I used the row number as a part of the predicate. Now, knowing the database name, I can create dynamic T-SQL to be executed using the sp_sqlexec stored procedure (see the code in red below). Finally, after all the tables for that given database have been placed in temporary table ##rawdata3, I increment the counter and continue on. Note that I used a global temporary table to ensure that the result set persists after the termination of the run. At some stage, I plan to redo this part of the code, as global temporary tables are not really an ideal solution. WHILE (@kounter < 25) BEGIN select @DatabaseName = database_name from #rawdata11 where recNo = @kounter set @SQL = 'Use ' + @DatabaseName + ' Insert into ##rawdata3 ' + + ' SELECT table_catalog,Table_name FROM information_schema.tables' exec sp_sqlexec @Sql SET @kounter = @kounter + 1 END The full code extract Here is the full code sample. declare @SQL varchar(max); declare @databasename varchar(75) /* drop table ##rawdata3 drop table #rawdata1 drop table #rawdata11 */ CREATE TABLE #rawdata1 ( database_name varchar(50) , database_size varchar(50), remarks Varchar(50) ) CREATE TABLE #rawdata11 ( recNo int identity(1,1), database_name varchar(50) , database_size varchar(50), remarks Varchar(50) ) CREATE TABLE ##rawdata3 ( database_name varchar(75) , table_name varchar(75), ) INSERT INTO #rawdata1 EXEC sp_databases go INSERT into #rawdata11 select * from #rawdata1 declare @kounter int; declare @databasename varchar(75); declare @sql varchar(max); set @kounter = 1 WHILE (@kounter < 25) BEGIN select @databasename = database_name from #rawdata11 where recNo = @kounter set @SQL = 'Use ' + @DatabaseName + ' Insert into ##rawdata3 ' + + ' SELECT table_catalog,Table_name FROM information_schema.tables' exec sp_sqlexec @Sql SET @kounter = @kounter + 1 END select * from ##rawdata3 where table_name like '%SalesOrderHeader%'

JavaOne Session Report: “50 Tips in 50 Minutes for GlassFish Fans”

- by Janice J. Heiss

At JavaOne 2012 on Monday, Oracle’s Engineer Chris Kasso, and Technology Evangelist Arun Gupta, presented a head-spinning session (CON4701) in which they offered 50 tips for GlassFish fans. Kasso and Gupta alternated back and forth with each presenting 10 tips at a time. An audience of about (appropriately) 50 attentive and appreciative developers was on hand in what has to be one of the most information-packed sessions ever at JavaOne!Aside: I experienced one of the quiet joys of JavaOne when, just before the session began, I spotted Java Champion and JavaOne Rock Star Adam Bien sitting nearby – Adam is someone I have been fortunate to know for many years.GlassFish is a freely available, commercially supported Java EE reference implementation. The session prioritized quantity of tips over depth of information and offered tips that are intended for both seasoned and new users, that are meant to increase the range of functional options available to GlassFish users. The focus was on lesser-known dimensions of GlassFish. Attendees were encouraged to pursue tips that contained new information for them. All 50 tips can be accessed here.Below are several examples of more elaborate tips and a final practical tip on how to get in touch with these folks. Tip #1: Using the login Command * To execute a remote command with asadmin you must provide the admin's user name and password.* The login command allows you to store the login credentials to be reused in subsequent commands.* Can be logged into multiple servers (distinguish by host and port).

Screenshot Tour: Ubuntu Touch 14.04 on a Nexus 7

- by Chris Hoffman

Ubuntu 14.04 LTS will “form the basis of the first commercially available Ubuntu tablets,” according to Canonical. We installed Ubuntu Touch 14.04 on our own hardware to see what those tablets will be like. We don’t recommend installing this yourself, as it’s still not a polished, complete experience. We’re using “Ubuntu Touch” as shorthand here — apparently this project’s new name is “Ubuntu For Devices.” The Welcome Screen Ubuntu’s touch interface is all about edge swipes and hidden interface elements — it has a lot in common with Windows 8, actually. You’ll see the welcome screen when you boot up or unlock a Ubuntu tablet or phone. If you have new emails, text messages, or other information, it will appear on this screen along with the time and date. If you don’t, you’ll just see a message saying “No data sources available.” The Dash Swipe in from the right edge of the welcome screen to access the Dash, or home screen. This is actually very similar to the Dash on Ubuntu’s Unity desktop. This isn’t a surprise — Canonical wants the desktop and touch versions of Ubuntu to use the same code. In the future, the desktop and touch versions of Ubuntu will use the same version of Unity and Unity will adjust its interface depending on what type of device your’e using. Here you’ll find apps you have installed and apps available to install. Tap an installed app to launch it or tap an available app to view more details and install it. Tap the My apps or Available headings to view a complete list of apps you have installed or apps you can install. Tap the Search box at the top of the screen to start searching — this is how you’d search for new apps to install. As you’d expect, a touch keyboard appears when you tap in the Search field or any other text field. The launcher isn’t just for apps. Tap the Apps heading at the top of the screen and you’ll see hidden text appear — Music, Video, and Scopes. This hidden navigation is used throughout Ubuntu’s different apps and can be easy to miss at first. Swipe to the left or right to move between these screens. These screens are also similar to the different panels in Unity on the desktop. The Scopes section allows you to view different search scopes you have installed. These are used to search different sources when you start a search from the Dash. Search from the Music or Videos scopes to search for local media files on your device or media files online. For example, searching in the Music scope will show you music results from Grooveshark by default. Navigating Ubuntu Touch Swipe in from the left edge anywhere on the system to open the launcher, a bar with shortcuts to apps. This launcher is very similar to the launcher on the left of Ubuntu’s Unity desktop — that’s the whole idea, after all. Once you’ve opened an app, you can leave the app by swiping in from the left. The launcher will appear — keep moving your finger towards the right edge of teh screen. This will swipe the current app off the screen, taking you back to the Dash. Once back on the Dash, you’ll see your open apps represented as thumbnails under Recent. Tap a thumbnail here to go back to a running app. To remove an app from here, long-press it and tap the X button that appears. Swipe in from the right edge in any app to quickly switch between recent apps. Swipe in from the right edge and hold your finger down to reveal an application switcher that shows all your recent apps and lets you choose between them. Swipe down from the top of the screen to access the indicator panel. Here you can connect to Wi-Fi networks, view upcoming events, control GPS and Bluetooth hardware, adjust sound settings, see incoming messages, and more. This panel is for quick access to hardware settings and notifications, just like the indicators on Ubuntu’s Unity desktop. The Apps System settings not included in the pull-down panel are available in the System Settings app. To access it, tap My apps on the Dash and tap System Settings, search for the System Settings app, or open the launcher bar and tap the settings icon. The settings here a bit limited compared to other operating systems, but many of the important options are available here. You can add Evernote, Ubuntu One, Twitter, Facebook, and Google accounts from here. A free Ubuntu One account is mandatory for downloading and updating apps. A Google account can be used to sync contacts and calendar events. Some apps on Ubuntu are native apps, while many are web apps. For example, the Twitter, Gmail, Amazon, Facebook, and eBay apps included by default are all web apps that open each service’s mobile website as an app. Other applications, such as the Weather, Calendar, Dialer, Calculator, and Notes apps are native applications. Theoretically, both types of apps will be able to scale to different screen resolutions. Ubuntu Touch and Ubuntu desktop may one day share the same apps, which will adapt to different display sizes and input methods. Like Windows 8 apps, Ubuntu apps hide interface elements by default, providing you with a full-screen view of the content. Swipe up from the bottom of an app’s screen to view its interface elements. For example, swiping up from the bottom of the Web Browser app reveals Back, Forward, and Refresh buttons, along with an address bar and Activity button so you can view current and recent web pages. Swipe up even more from the bottom and you’ll see a button hovering in the middle of the app. Tap the button and you’ll see many more settings. This is an overflow area for application options and functions that can’t fit on the navigation bar. The Terminal app has a few surprising Easter eggs in this panel, including a “Hack into the NSA” option. Tap it and the following text will appear in the terminal: That’s not very nice, now tracing your location . . . . . . . . . . . .Trace failed You got away this time, but don’t try again. We’d expect to see such Easter eggs disappear before Ubuntu Touch actually ships on real devices. Ubuntu Touch has come a long way, but it’s still not something you want to use today. For example, it doesn’t even have a built-in email client — you’ll have to us your email service’s mobile website. Few apps are available, and many of the ones that are are just mobile websites. It’s not a polished operating system intended for normal users yet — it’s more of a preview for developers and device manufacturers. If you really want to try it yourself, you can install it on a Wi-Fi Nexus 7 (2013), Nexus 10, or Nexus 4 device. Follow Ubuntu’s installation instructions here.

Azure Task Scheduling Options

- by charlie.mott

Currently, the Azure PaaS does not offer a distributed\resilient task scheduling service. If you do want to host a task scheduling product\solution off-premise (and ideally use Azure), what are your options? PaaS Option 1: Worker Roles Use a worker role to schedule and execute actions at specific time periods. There are a few frameworks available to assist with this: http://azuretoolkit.codeplex.com https://github.com/Lokad/lokad-cloud/wiki/TaskScheduler http://blog.smarx.com/posts/building-a-task-scheduler-in-windows-azure - This addresses a slightly different set of requirements. It’s a more dynamic approach for queuing up tasks, but not repeatable tasks (e.g. daily). I found the Azure Toolkit option the most simple to implement. Step 1 : Create a domain entity implementing IJob for each job to schedule. In this sample, I asynchronously call a WCF service method. 1: namespace Acme.WorkerRole.Jobs 2: { 3: using AzureToolkit; 4: using ScheduledTasksService; 5: 6: public class UploadEmployeesJob : IJob 7: { 8: public void Run() 9: { 10: // Call Tasks Service 11: var client = new ScheduledTasksServiceClient("BasicHttpBinding_IScheduledTasksService"); 12: client.UploadEmployees(); 13: client.Close(); 14: } 15: } 16: } Step 2 : In the worker role run method, add the jobs to the toolkit engine. 1: namespace Acme.WorkerRole 2: { 3: using AzureToolkit.Engine; 4: using Jobs; 5: 6: public class WorkerRole : WorkerRoleEntryPoint 7: { 8: public override void Run() 9: { 10: var engine = new CloudEngine(); 11: 12: // Add Scheduled Jobs (using CronJob syntax - see http://www.adminschoice.com/crontab-quick-reference). 13: 14: // 1. Upload Employee job - 8.00 PM every weekday (Mon-Fri) 15: engine.WithJobScheduler().ScheduleJob<UploadEmployeesJob>(c => { c.CronSchedule = "0 20 * * 1-5"; }); 16: // 2. Purge Data job - 10 AM every Saturday 17: engine.WithJobScheduler().ScheduleJob<PurgeDataJob>(c => { c.CronSchedule = "0 10 * * 6"; }); 18: // 3. Process Exceptions job - Every 5 minutes 19: engine.WithJobScheduler().ScheduleJob<ProcessExceptionsJob>(c => { c.CronSchedule = "*/5 * * * *"; }); 20: 21: engine.Run(); 22: base.Run(); 23: } 24: } 25: } Pros Cons Azure Toolkit option is simple to implement. For the AzureToolkit option, you are limited to a single worker role. Otherwise, the jobs will be executed multiple times, once for each worker role instance. Paying for a continuously running worker role, even if it just processes a single job once a week. If you only have a few scheduled tasks to run calling asynchronous services hosted in different web roles, an extra small worker role likely to be sufficient. However, for an extra small worker role this still costs $14.40/month (03/09/2012). Option 2: Use Scheduled Task on Azure Web Role calling a console app Setup a Windows Scheduled Task on the Azure Web Role. This calls a console application that calls the WCF service methods that run the task actions. This design is described here: http://www.ronaldwidha.net/2011/02/23/cron-job-on-azure-using-scheduled-task-on-a-web-role-to-replace-azure-worker-role-for-background-job/ http://www.voiceoftech.com/swhitley/index.php/2011/07/windows-azure-task-scheduler/ http://devlicio.us/blogs/vinull/archive/2011/10/23/moving-to-azure-worker-roles-for-nothing-and-tasks-for-free.aspx Pros Cons Fairly easy to implement. Supportability - I RDC’ed onto the Azure server and stopped the scheduled task. I then rebooted the machine and the task was re-started. I also tried deleting the task and rebooting, the same thing occurred. The only way to permanently guarantee that a task is disabled is to do a fresh deployment. I think this is a major supportability concern. Saleability - multiple instances would trigger multiple tasks. You can only have one instance for the scheduled task web role. The guidance implements setup of the scheduled task as part of a web role instance. But if you have more than one instance in a web role, the task will be triggered multiple times for each scheduled action (once per machine). Workaround: If we wanted to use scheduled tasks for another client with a saleable WCF service, then we could include the console & tasks scripts in a separate web role (e.g. a empty WCF service with no real purpose to it). SaaS Option 3: Azure Marketplace I thought that someone might be offering this type of service via the Azure marketplace. At the point of writing this blog post, I did not find anyone doing so. https://datamarket.azure.com/ Pros Cons Nobody currently offers this on the Azure Marketplace. Option 4: Online Job Scheduling Service Provider There are plenty of online providers that offer this type of service on a pay-as-you-go approach. Some of these are free for small usage. Many of these providers are listed here: http://en.wikipedia.org/wiki/Webcron Pros Cons No bespoke development for scheduler. Reliance on third party. IaaS Option 5: Setup Scheduling Software on Azure IaaS VM’s One of job scheduling software offerings could be installed and configured on Azure VM’s. A list of software options is listed here: http://en.wikipedia.org/wiki/List_of_job_scheduler_software Pros Cons Enterprise distributed\resilient task scheduling service VM Setup and maintenance Software Licence Costs Option 6: VM Gallery A the time of writing this blog post, I did not spot a VM in the gallery that included pre-installation of any of the above software options. Pros Cons No current VM template. Summary For my current project that had a small handful of tasks to schedule with a limited project budget I chose option 1 (a worker role using the Azure Toolkit to schedule tasks). If I was building an enterprise scale solution for the future, options 4 and 5 are currently worthy of consideration. Hopefully, Microsoft will include tasks scheduling in the future as part of their PaaS offerings.

Automatic Maintenance Jobs in every PDB? New SPM Evolve Advisor Task in Oracle 12.1.0.2

- by Mike Dietrich

A customer checking out our slides from the OTN Tour in August 2014 asked me a finicky question the other day: "According to the documentation the Automatic SQL Tuning Advisor maintenance task gets executed only within the CDB$ROOT, but not within each PDB - but the slides are not clear here. So what is the truth?" Ok, that's good question. In my understanding all tasks will get executed within each PDB - that's why we recommend (based on experience) to break up the default maintenance windows when using Oracle Multitenant. Otherwise all PDBs will have the same maintenance windows, and guess what will happen when 25 PDBs start gathering object statistics at the same time ... The documentation indeed says: Automatic SQL Tuning Advisor data is stored in the root. It might have results about SQL statements executed in a PDB that were analyzed by the advisor, but these results are not included if the PDB is unplugged. A common user whose current container is the root can run SQL Tuning Advisor manually for SQL statements from any PDB. When a statement is tuned, it is tuned in any container that runs the statement. This sounds reasonable. But when we have a look into our PDBs or into the CDB_AUTOTASK_CLIENT view the result is different from what the doc says. In my environment I did create just two fresh empty PDBs (CON_ID 3 and 4): SQL> select client_name, status, con_id from cdb_autotask_client; CLIENT_NAME STATUS CON_ID------------------------------------- ---------- ----------auto optimizer stats collection ENABLED 1sql tuning advisor ENABLED 1auto space advisor ENABLED 1auto optimizer stats collection ENABLED 4sql tuning advisor ENABLED 4auto space advisor ENABLED 4auto optimizer stats collection ENABLED 3sql tuning advisor ENABLED 3auto space advisor ENABLED 3 9 rows selected. I haven't verified the reason why this is different from the docs but it may have been related to one change in Oracle Database 12.1.0.2: The new SPM Evolve Advisor Task ( SYS_AUTO_SPM_EVOLVE_TASK) for automatic plan evolution for SQL Plan Management. This new task doesn't appear as a stand-alone job (client) in the maintenance window but runs as a sub-entity of the Automatic SQL Tuning Advisor task. And (I'm just guessing) this may be one of the reasons why every PDB will have to have its own Automatic SQL Tuning Advisor task Here you'll find more information about how to enable, disable and configure the new Oracle 12.1.0.2 SPM Evolve Advisor Task: Oracle Database 12.1.0.2 SQL Tuning Guide:Managing the SPM Evolve Advisor Task -Mike

Clouds Everywhere But not a Drop of Rain – Part 3

- by sxkumar

I was sharing with you how a broad-based transformation such as cloud will increase agility and efficiency of an organization if process re-engineering is part of the plan. I have also stressed on the key enterprise requirements such as “broad and deep solutions, “running your mission critical applications” and “automated and integrated set of capabilities”. Let me walk you through some key cloud attributes such as “elasticity” and “self-service” and what they mean for an enterprise class cloud. I will also talk about how we at Oracle have taken a very enterprise centric view to developing cloud solutions and how our products have been specifically engineered to address enterprise cloud needs. Cloud Elasticity and Enterprise Applications Requirements Easy and quick scalability for a short-period of time is the signature of cloud based solutions. It is this elasticity that allows you to dynamically redistribute your resources according to business priorities, helps increase your overall resource utilization, and reduces operational costs by allowing you to get the most out of your existing investment. Most public clouds are offering a instant provisioning mechanism of compute power (CPU, RAM, Disk), customer pay for the instance-hours(and bandwidth) they use, adding computing resources at peak times and removing them when they are no longer needed. This type of “just-in-time” serving of compute resources is well known for mid-tiers “state less” servers such as web application servers and web servers that just need another machine to start and run on it but what does it really mean for an enterprise application and its underlying data? Most enterprise applications are not as quite as “state less” and justifiably so. As such, how do you take advantage of cloud elasticity and make it relevant for your enterprise apps? This is where Cloud meets Grid Computing. At Oracle, we have invested enormous amount of time, energy and resources in creating enterprise grid solutions. All our technology products offer built-in elasticity via clustering and dynamic scaling. With products like Real Application Clusters (RAC), Automatic Storage Management, WebLogic Clustering, and Coherence In-Memory Grid, we allow all your enterprise applications to benefit from Cloud elasticity –both vertically and horizontally - without requiring any application changes. A number of technology vendors take a rather simplistic route of starting up additional or removing unneeded VM as the "Cloud Scale-Out" solution. While this may work for stateless mid-tier servers where load balancers can handle the addition and remove of instances transparently but following a similar approach for the database tier - often called as "database sharding" - requires significant application modification and typically does not work with off the shelf packaged applications. Technologies like Oracle Database Real Application Clusters, Automatic Storage Management, etc. on the other hand bring the benefits of incremental scalability and on-demand elasticity to ANY application by providing a simplified abstraction layers where the application does not need deal with data spread over multiple database instances. Rather they just talk to a single database and the database software takes care of aggregating resources across multiple hardware components. It is the technologies like these that truly make a cloud solution relevant for enterprises. For customers who are looking for a next generation hardware consolidation platform, our engineered systems (e.g. Exadata, Exalogic) not only provide incredible amount of performance and capacity, they also reduce the data center complexity and simplify operations. Assemble, Deploy and Manage Enterprise Applications for Cloud Products like Oracle Virtual assembly builder (OVAB) resolve the complex problem of bringing the cloud speed to complex multi-tier applications. With assemblies, you can not only provision all components of a multi-tier application and wire them together by push of a button, other aspects of application lifecycle, such as real-time application testing, scale-up/scale-down, performance and availability monitoring, etc., are also automated using Oracle Enterprise Manager. An essential criteria for an enterprise cloud to succeed is the ability to ensure business service levels especially when business users have either full visibility on the usage cost with a “show back” or a “charge back”. With Oracle Enterprise Manager 12c, we have created the most comprehensive cloud management solution in the industry that is capable of managing business service levels “applications-to-disk” in a enterprise private cloud – all from a single console. It is the only cloud management platform in the industry that allows you to deliver infrastructure, platform and application cloud services out of the box. Moreover, it offers integrated and complete lifecycle management of the cloud - including planning and set up, service delivery, operations management, metering and chargeback, etc . Sounds unbelievable? Well, just watch this space for more details on how Oracle Enterprise Manager 12c is the nerve center of Oracle Cloud! Our cloud solution portfolio is also the broadest and most deep in the industry - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry. And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. Summary But the intent of this blog post isn't to dwell on how great our solutions are (these are just some examples to illustrate how we at Oracle have approached this problem space). Rather it is to help you ask the right questions before you embark on your cloud journey. So to summarize, here are the key takeaways. It is critical that you are clear on why you are building the cloud. Successful organizations keep business benefits as the first and foremost cloud objective. On the other hand, those who approach this purely as a technology project are more likely to fail. Think about where you want to be in 3-5 years before you get started. Your long terms objectives should determine what your first step ought to be. As obvious as it may seem, more people than not make the first move without knowing where they are headed. Don’t make the mistake of equating cloud to virtualization and Infrastructure-as-a-Service (IaaS). Spinning a VM on-demand will give some short term relief to your IT staff but is unlikely to solve your larger business problems. As such, even if IaaS is your first step towards a more comprehensive cloud, plan the roadmap around those higher level services before you begin. And ask your vendors on how they are going to be your partners in this journey. Capabilities like self-service access and chargeback/showback are absolutely critical if you really expect your cloud to be transformational. Your business won't see the full benefits of the cloud until it empowers them with same kind of control and transparency that they are used to while using a public cloud service. Evaluate the benefits of integration, as opposed to blindly following the best-of-breed strategy. Integration is a huge challenge and more so in a cloud environment. There are enormous costs associated with stitching a solution out of disparate components and even more in maintaining it. Hope you found these ideas helpful. Looking forward to hearing your thoughts and experiences.

What's up with LDoms: Part 5 - A few Words about Consoles

- by Stefan Hinker

Back again to look at a detail of LDom configuration that is often forgotten - the virtual console server. Remember, LDoms are SPARC systems. As such, each guest will have it's own OBP running. And to connect to that OBP, the administrator will need a console connection. Since it's OBP, and not some x86 BIOS, this console will be very serial in nature ;-) It's really very much like in the good old days, where we had a terminal concentrator where all those serial cables ended up in. Just like with other components in LDoms, the virtualized solution looks very similar. Every LDom guest requires exactly one console connection. Envision this similar to the RS-232 port on older SPARC systems. The LDom framework provides one or more console services that provide access to these connections. This would be the virtual equivalent of a network terminal server (NTS), where all those serial cables are plugged in. In the physical world, we'd have a list somewhere, that would tell us which TCP-Port of the NTS was connected to which server. "ldm list" does just that: root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- UART 16 7680M 0.4% 27d 8h 22m jupiter bound ------ 5002 20 8G mars active -n---- 5000 2 8G 0.5% 55d 14h 10m venus active -n---- 5001 2 8G 0.5% 56d 40m pluto inactive ------ 4 4G The column marked "CONS" tells us, where to reach the console of each domain. In the case of the primary domain, this is actually a (more) physical connection - it's the console connection of the physical system, which is either reachable via the ILOM of that system, or directly via the serial console port on the chassis. All the other guests are reachable through the console service which we created during the inital setup of the system. Note that pluto does not have a port assigned. This is because pluto is not yet bound. (Binding can be viewed very much as the assembly of computer parts - CPU, Memory, disks, network adapters and a serial console cable are all put together when binding the domain.) Unless we set the port number explicitly, LDoms Manager will do this on a first come, first serve basis. For just a few domains, this is fine. For larger deployments, it might be a good idea to assign these port numbers manually using the "ldm set-vcons" command. However, there is even better magic associated with virtual consoles. You can group several domains into one console group, reachable through one TCP port of the console service. This can be useful when several groups of administrators are to be given access to different domains, or for other grouping reasons. Here's an example: root@sun # ldm set-vcons group=planets service=console jupiter root@sun # ldm set-vcons group=planets service=console pluto root@sun # ldm bind jupiter root@sun # ldm bind pluto root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- UART 16 7680M 6.1% 27d 8h 24m jupiter bound ------ 5002 200 8G mars active -n---- 5000 2 8G 0.6% 55d 14h 12m pluto bound ------ 5002 4 4G venus active -n---- 5001 2 8G 0.5% 56d 42m root@sun # telnet localhost 5002 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. sun-vnts-planets: h, l, c{id}, n{name}, q:l DOMAIN ID DOMAIN NAME DOMAIN STATE 2 jupiter online 3 pluto online sun-vnts-planets: h, l, c{id}, n{name}, q:npluto Connecting to console "pluto" in group "planets" .... Press ~? for control options .. What I did here was add the two domains pluto and jupiter to a new console group called "planets" on the service "console" running in the primary domain. Simply using a group name will create such a group, if it doesn't already exist. By default, each domain has its own group, using the domain name as the group name. The group will be available on port 5002, chosen by LDoms Manager because I didn't specify it. If I connect to that console group, I will now first be prompted to choose the domain I want to connect to from a little menu. Finally, here's an example how to assign port numbers explicitly: root@sun # ldm set-vcons port=5044 group=pluto service=console pluto root@sun # ldm bind pluto root@sun # ldm list NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- UART 16 7680M 3.8% 27d 8h 54m jupiter active -t---- 5002 200 8G 0.5% 30m mars active -n---- 5000 2 8G 0.6% 55d 14h 43m pluto bound ------ 5044 4 4G venus active -n---- 5001 2 8G 0.4% 56d 1h 13m With this, pluto would always be reachable on port 5044 in its own exclusive console group, no matter in which order other domains are bound. Now, you might be wondering why we always have to mention the console service name, "console" in all the examples here. The simple answer is because there could be more than one such console service. For all "normal" use, a single console service is absolutely sufficient. But the system is flexible enough to allow more than that single one, should you need them. In fact, you could even configure such a console service on a domain other than the primary (or control domain), which would make that domain a real console server. I actually have a customer who does just that - they want to separate console access from the control domain functionality. But this is definately a rather sophisticated setup. Something I don't want to go into in this post is access control. vntsd, which is the daemon providing all these console services, is fully RBAC-aware, and you can configure authorizations for individual users to connect to console groups or individual domain's consoles. If you can't wait until I get around to security, check out the man page of vntsd. Further reading: The Admin Guide is rather reserved on this subject. I do recommend to check out the Reference Manual. The manpage for vntsd will discuss all the control sequences as well as the grouping and authorizations mentioned here.

How to Plug a Small Hole in NetBeans JSF (Join Table) Code Generation

- by MarkH

I was asked recently to provide an assist with designing and building a small-but-vital application that had at its heart some basic CRUD (Create, Read, Update, & Delete) functionality, built upon an Oracle database, to be accessible from various locations. Working from the stated requirements, I fleshed out the basic application and database designs and, once validated, set out to complete the first iteration for review. Using SQL Developer, I created the requisite tables, indices, and sequences for our first run. One of the tables was a many-to-many join table with three fields: one a primary key for that table, the other two being primary keys for the other tables, represented as foreign keys in the join table. Here is a simplified example of the trio of tables: Once the database was in decent shape, I fired up NetBeans to let it have first shot at the code. NetBeans does a great job of generating a mountain of essential code, saving developers what must be millions of hours of effort each year by building a basic foundation with a few clicks and keystrokes. Lest you think it (or any tool) can do everything for you, however, occasionally something tosses a paper clip into the delicate machinery and makes you open things up to fix them. Join tables apparently qualify. :-) In the case above, the entity class generated for the join table (New Entity Classes from Database) included an embedded object consisting solely of the two foreign key fields as attributes, in addition to an object referencing each one of the "component" tables. The Create page generated (New JSF Pages from Entity Classes) worked well to a point, but when trying to save, we were greeted with an error: Transaction aborted. Hmm. A quick debugger session later and I'd identified the issue: when trying to persist the new join-table object, the embedded "foreign-keys-only" object still had null values for its two (required value) attributes...even though the embedded table objects had populated key attributes. Here's the simple fix: In the join-table controller class, find the public String create() method. It will look something like this: public String create() { try { getFacade().create(current); JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("JoinEntityCreated")); return prepareCreate(); } catch (Exception e) { JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured")); return null; } } To restore balance to the force, modify the create() method as follows (changes in red): public String create() { try { // Add the next two lines to resolve: current.getJoinEntityPK().setTbl1id(current.getTbl1().getId().toBigInteger()); current.getJoinEntityPK().setTbl2id(current.getTbl2().getId().toBigInteger()); getFacade().create(current); JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("JoinEntityCreated")); return prepareCreate(); } catch (Exception e) { JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured")); return null; } } I'll be refactoring this code shortly, but for now, it works. Iteration one is complete and being reviewed, and we've met the milestone. Here's to happy endings (and customers)! All the best,Mark

Entity Framework 6: Alpha2 Now Available

- by ScottGu

The Entity Framework team recently announced the 2nd alpha release of EF6. The alpha 2 package is available for download from NuGet. Since this is a pre-release package make sure to select “Include Prereleases” in the NuGet package manager, or execute the following from the package manager console to install it: PM> Install-Package EntityFramework -Pre This week’s alpha release includes a bunch of great improvements in the following areas: Async language support is now available for queries and updates when running on .NET 4.5. Custom conventions now provide the ability to override the default conventions that Code First uses for mapping types, properties, etc. to your database. Multi-tenant migrations allow the same database to be used by multiple contexts with full Code First Migrations support for independently evolving the model backing each context. Using Enumerable.Contains in a LINQ query is now handled much more efficiently by EF and the SQL Server provider resulting greatly improved performance. All features of EF6 (except async) are available on both .NET 4 and .NET 4.5. This includes support for enums and spatial types and the performance improvements that were previously only available when using .NET 4.5. Start-up time for many large models has been dramatically improved thanks to improved view generation performance. Below are some additional details about a few of the improvements above: Async Support .NET 4.5 introduced the Task-Based Asynchronous Pattern that uses the async and await keywords to help make writing asynchronous code easier. EF 6 now supports this pattern. This is great for ASP.NET applications as database calls made through EF can now be processed asynchronously – avoiding any blocking of worker threads. This can increase scalability on the server by allowing more requests to be processed while waiting for the database to respond. The following code shows an MVC controller that is querying a database for a list of location entities: public class HomeController : Controller { LocationContext db = new LocationContext(); public async Task<ActionResult> Index() { var locations = await db.Locations.ToListAsync(); return View(locations); } } Notice above the call to the new ToListAsync method with the await keyword. When the web server reaches this code it initiates the database request, but rather than blocking while waiting for the results to come back, the thread that is processing the request returns to the thread pool, allowing ASP.NET to process another incoming request with the same thread. In other words, a thread is only consumed when there is actual processing work to do, allowing the web server to handle more concurrent requests with the same resources. A more detailed walkthrough covering async in EF is available with additional information and examples. Also a walkthrough is available showing how to use async in an ASP.NET MVC application. Custom Conventions When working with EF Code First, the default behavior is to map .NET classes to tables using a set of conventions baked into EF. For example, Code First will detect properties that end with “ID” and configure them automatically as primary keys. However, sometimes you cannot or do not want to follow those conventions and would rather provide your own. For example, maybe your primary key properties all end in “Key” instead of “Id”. Custom conventions allow the default conventions to be overridden or new conventions to be added so that Code First can map by convention using whatever rules make sense for your project. The following code demonstrates using custom conventions to set the precision of all decimals to 5. As with other Code First configuration, this code is placed in the OnModelCreating method which is overridden on your derived DbContext class: protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Properties<decimal>() .Configure(x => x.HasPrecision(5)); } But what if there are a couple of places where a decimal property should have a different precision? Just as with all the existing Code First conventions, this new convention can be overridden for a particular property simply by explicitly configuring that property using either the fluent API or a data annotation. A more detailed description of custom code first conventions is available here. Community Involvement I blogged a while ago about EF being released under an open source license. Since then a number of community members have made contributions and these are included in EF6 alpha 2. Two examples of community contributions are: AlirezaHaghshenas contributed a change that increases the startup performance of EF for larger models by improving the performance of view generation. The change means that it is less often necessary to use of pre-generated views. UnaiZorrilla contributed the first community feature to EF: the ability to load all Code First configuration classes in an assembly with a single method call like the following: protected override void OnModelCreating(DbModelBuilder modelBuilder) { modelBuilder.Configurations .AddFromAssembly(typeof(LocationContext).Assembly); } This code will find and load all the classes that inherit from EntityTypeConfiguration<T> or ComplexTypeConfiguration<T> in the assembly where LocationContext is defined. This reduces the amount of coupling between the context and Code First configuration classes, and is also a very convenient shortcut for large models. Other upcoming features coming in EF 6 Lots of information about the development of EF6 can be found on the EF CodePlex site, including a roadmap showing the other features that are planned for EF6. One of of the nice upcoming features is connection resiliency, which will automate the process of retying database operations on transient failures common in cloud environments and with databases such as the Windows Azure SQL Database. Another often requested feature that will be included in EF6 is the ability to map stored procedures to query and update operations on entities when using Code First. Summary EF6 is the first open source release of Entity Framework being developed in CodePlex. The alpha 2 preview release of EF6 is now available on NuGet, and contains some really great features for you to try. The EF team are always looking for feedback from developers - especially on the new features such as custom Code First conventions and async support. To provide feedback you can post a comment on the EF6 alpha 2 announcement post, start a discussion or file a bug on the CodePlex site. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

Accessing your web server via IPv6

Being able to run your systems on IPv6, have automatic address assignment and the ability to resolve host names are the necessary building blocks in your IPv6 network infrastructure. Now, that everything is in place it is about time that we are going to enable another service to respond to IPv6 requests. The following article will guide through the steps on how to enable Apache2 httpd to listen and respond to incoming IPv6 requests. This is the fourth article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. Surfing the web - IPv6 style Enabling IPv6 connections in Apache 2 is fairly simply. But first let's check whether your system has a running instance of Apache2 or not. You can check this like so: $ service apache2 status Apache2 is running (pid 2680). In case that you got a 'service unknown' you have to install Apache to proceed with the following steps: $ sudo apt-get install apache2 Out of the box, Apache binds to all your available network interfaces and listens to TCP port 80. To check this, run the following command: $ sudo netstat -lnptu | grep "apache2\W*$"tcp6 0 0 :::80 :::* LISTEN 28306/apache2 In this case Apache2 is already binding to IPv6 (and implicitly to IPv4). If you only got a tcp output, then your HTTPd is not yet IPv6 enabled. Check your Listen directive, depending on your system this might be in a different location than the default in Ubuntu. $ sudo nano /etc/apache2/ports.conf # If you just change the port or add more ports here, you will likely also# have to change the VirtualHost statement in# /etc/apache2/sites-enabled/000-default# This is also true if you have upgraded from before 2.2.9-3 (i.e. from# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and# README.Debian.gzNameVirtualHost *:80Listen 80<IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP. Listen 443</IfModule><IfModule mod_gnutls.c> Listen 443</IfModule> Just in case that you don't have a ports.conf file, look for it like so: $ cd /etc/apache2/$ fgrep -r -i 'listen' ./* And modify the related file instead of the ports.conf. Which most probably might be either apache2.conf or httpd.conf anyways. Okay, please bear in mind that Apache can only bind once on the same interface and port. So, eventually, you might be interested to add another port which explicitly listens to IPv6 only. In that case, you would add the following in your configuration file: Listen 80Listen [2001:db8:bad:a55::2]:8080 But this is completely optional... Anyways, just to complete all steps, you save the file, and then check the syntax like so: $ sudo apache2ctl configtestSyntax OK Ok, now let's apply the modifications to our running Apache2 instances: $ sudo service apache2 reload * Reloading web server config apache2 ...done. $ sudo netstat -lnptu | grep "apache2\W*$" tcp6 0 0 2001:db8:bad:a55:::8080 :::* LISTEN 5922/apache2 tcp6 0 0 :::80 :::* LISTEN 5922/apache2 There we have two daemons running and listening to different TCP ports. Now, that the basics are in place, it's time to prepare any website to respond to incoming requests on the IPv6 address. Open up any configuration file you have below your sites-enabled folder. $ ls -al /etc/apache2/sites-enabled/... $ sudo nano /etc/apache2/sites-enabled/000-default <VirtualHost *:80 [2001:db8:bad:a55::2]:8080> ServerAdmin [email protected] ServerName server.ios.mu ServerAlias server Here, we have to check and modify the VirtualHost directive and enable it to respond to the IPv6 address and port our web server is listening to. Save your changes, run the configuration test and reload Apache2 in order to apply your modifications. After successful steps you can launch your favourite browser and navigate to your IPv6 enabled web server. Accessing an IPv6 address in the browser That looks like a successful surgery to me... Note: In case that you received a timeout, check whether your client is operating on IPv6, too.

Nokia Windows Phone 8 App Collection

- by Tim Murphy

I recently upgraded to a Nokia Lumia 920. Along with it came the availability of a number of Nokia developed apps or apps that Nokia has made available from other developers. Below is a summary of some of the ones that I have used to this point. There are quite a few of them so I won’t be covering everything that is available. Nokia Maps I am quite pleased with the accuracy of Nokia Maps and not having to tap the screen for each turn any more. The information on the screen is quite good as well. The couple of improvements I would like to see are for the voice directions to include which street or exit you need to use and improve the search accuracy. Bing maps had much better search results in my opinion. Nokia Drive This one really had me confused when I first setup the phone. I was driving down the road and suddenly I am getting notification tones, but there were no visual notifications on the phone. It seems that in their infinite wisdom Nokia thinks I don’t know when I am going over the speed limit and need to be told. ESPN I really liked my ESPN app on Windows Phone 7.5, but I am not getting the type of experience I was looking for out of this app. While it allows me to pick my favorite teams, but there isn’t a pivot page or panorama page that shows a summary of my favorite teams. I have also found that the live tile don’t update very often. Over all I am rather disappointed compared app produced by ESPN. Smart Shoot I really need to get the kids to let me use this on. I like the concept, but I need to spend more time with it. The idea how running the camera through a continuous shooting mode and then picking the best is something that I have done with my DSLR and am glad to see it available here. Cinemagraph Here is a fun filter. It doesn’t have the most accurate editing features, but it is fun to stop certain parts of a scene and let other parts move. As a test I stopped the traffic on the highway and let the traffic on the frontage road flow. It makes for a fun effect. If nothing else it could be great for sending prank animations to your friends. YouSendIt I have only briefly touched this application. What I don’t understand is why it is needed. Most of the functionality seems to be similar to SkyDrive and it gives you less storage. They only feature that seems to differentiate the app is the signature capability. Creative Studio This app has some nice quick edits, but it is not very comprehensive. I am also not to thrilled with the user experience. It puts you though an initial color cast series that I’m not sure why it is there. Discovery of the remaining adjustments isn’t that great. In the end I found myself wanting Thumbia back. Panorama This is one of the apps that I like. I found it easy to use as it guides you with a target circle that you center for it to take the next pictures. It also stitches the images with amazing speed. The one thing I wish it had was the capability to turn the phone into portrait orientation and do a taller panorama. Perhaps we will see this in the future. Nokia Music After getting over the missing album art I found that there were a number of missing features with this app as well. I have a Zune HD and I am used to being able to go through my collection and adding songs, albums or artists to my now playing. There also doesn’t seem to be a way to manage playlists that I have seen yet. Other than that the UI is familiar and it give Nokia City Lens Augmented reality is a cool concept, but I still haven’t seen it implemented in a compelling fashion beyond a demo at TED a couple of years ago. The app still leaves me wanting as well. It does give an interesting toy. It gives you the ability to look for general categories and see general direction and clusters of locations. I think as this concept is better thought out it will become more compelling. Nokia Trailers I don’t know how often I will use this app, but I do like being able to see what movies are being promoted. I can’t wait for The Hobbit to come out and the trailer was just what the doctor ordered. I can see coming back to this app from time to time. PhotoBeamer PhotoBeamer is a strange beast that needs a better instruction manual. It seems a lot like magic but very confusing. I need some more testing, but I don’t think this is something that most people are going to understand quickly and may give up before getting it to work. I may put an update here after playing with it further. Ringtone Maker The app was just published and it didn’t work very well for me. It couldn’t find 95% of the songs that Nokia Music was playing for me and crashed several times. It also had songs named wrong that when I checked them in Nokia Music they were fine. This app looks like it has a long way to go. Summary In all I think that Nokia is offering a well rounded set of initial applications that can get any new owner started. There is definitely room for improvement in all of these apps. The main need is usability upgrades. I would guess that with feedback from users they will come up to acceptable levels. Try them out and see if you agree. del.icio.us Tags: Windows Phone,Nokia,Lumia,Nokia Apps,ESPN,PhotoBeamer,City Lens,YouSendIt,Drive,Maps

Sending notification after an event has remained open for a specified period

- by Loc Nhan

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Enterprise Manager (EM) 12c allows you to create an incident rule to send a notification and/or create an incident after an event has been open for a specified period. Such an incident rule will help prevent premature alerts on issues that may correct themselves within a certain amount of time. For example, there are some agents in an unstable network area, and often there are communication failures between the agents and the OMS lasting three, four minutes at a time. In this scenario, you may only want to receive alerts after an agent in that area has been in the Agent Unreachable status for at least five minutes. Note: Many non-target availability metrics allow users to specify the “number of occurrences” or the number of consecutive times metric values reach thresholds before a notification is sent. It is best to use the feature for such metrics. This article provides a step-by-step guide for creating an incident rule set to cater for the above scenario, that is, to create an incident and send a notification after the Agent Unreachable event has remained open for a five-minute duration. Steps to create the incident rule 1. Log on to the console and navigate to Setup -> Incidents -> Incident Rules. Note: A non-super user requires the Create Enterprise Rule Set privilege, which is a resource privilege, to create an incident rule. The Incident Rules - All Enterprise Rules page displays. 2. Click Create Rule Set … The Create Rule Set page displays. 3. Enter a name for the rule set (e.g. Rule set for agents in flaky network areas), optionally enter a description, and leave everything else at default values, and click + Add. The Search and Select: Targets page pops up. Note: While you can create a rule set for individual targets, it is a best practice to use a group for this purpose. 4. Select an appropriate group, e.g. the AgentsInFlakyNework group. The Select button becomes enabled, click the button. The Create Rule Set page displays. 5. Leave everything at default values, and click the Rules tab. The Create Rule Set page displays. 6. Click Create… The Select Type of Rule to Create page pops up. 7. Leave the Incoming events and updates to events option selected, and click Continue. The Create New Rule : Select Events page displays. 8. Select Target Availability from the Type drop-down list. The page shows more options for Target Availability. 9. Select the Specific events of type Target Availability option, and click + Add. The Select Target Availability events page pops up. 10. Select Agent from the Target Type dropdown list. The page expands. 11. Click the Agent unreachable checkbox, and click OK. Note: If you want to also receive a notification when the event is cleared, click the Agent unreachable end checkbox as well before clicking OK. The Create New Rule : Select Events page displays. 12. Click Next. The Create New Rule : Add Actions page displays. 13. Click + Add. The Add Actions page displays. 14. Do the following: a. Select the Only execute the actions if specified conditions match option (You don’t want the action to trigger always). The following options appear in the Conditions for Actions section. b. Select the Event has been open for specified duration option. The Conditions for actions section expands. c. Change the values of Event has been open for to 5 Minutes as shown below. d. In the Create Incident or Update Incident section, click the Create Incident checkbox as following: e. In the Notifications section, enter an appropriate EM user or email address in the E-mail To field. f. Click Continue (in the top right hand corner). The Create New Rule : Add Actions page displays. 15. Click Next. The Create New Rule : Specify name and Description page displays. 16. Enter a rule name, and click Next. The Create New Rule : Review page appears. 17. Click Continue, and proceed to save the rule set. The incident rule set creation completes. After one of the agents in the group specified in the rule set is stopped for over 5 minutes, EM will send a mail notification and create an incident as shown in the following screenshot. In conclusion, you have seen the steps to create an example incident rule set that only creates an incident and triggers a notification after an event has been open for a specified period. Such an incident rule can help prevent unnecessary incidents and alert notifications leaving EM administrators time to more important tasks. - Loc Nhan

How to split a string with negative numbers using ActionScript 3.0

- by inzombiak

I'm having trouble loading my level. I'm using Ogmo to create my level then I import it. I have no problem converting 0's and 1's into an Array, but I can't figure out how to do the same for -1's.

Beyond Cloud Technology, Enabling A More Agile and Responsive Organization

- by sxkumar

This is the second part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain”. In the first part, I was sharing with you how a broad-based transformation makes cloud more than a technology initiative, I will describe in this section how it requires people (organizational) and process changes as well, and these changes are as critical as is the choice of right tools and technology. People: Most IT organizations have a fairly complex organizational structure. There are different groups, managing different pieces of the puzzle, and yet, they don't always work together. Provisioning a new application therefore may require a request to float endlessly through system administrators, DBAs and middleware admin worlds – resulting in long delays and constant finger pointing. Cloud users expect end-to-end automation - which requires these silos to be greatly simplified, if not completely eliminated. Most customers I talk to acknowledge this problem but are quick to admit that such a transformation is hard. As hard as it may be, I am afraid that the status quo is no longer an option. Sticking to an organizational structure that was created ages back will not only impede cloud adoption, it also risks making the IT skills increasingly irrelevant in a world that is rapidly moving towards converged applications and infrastructure. Process: Most IT organizations today operate with a mindset that they must fully "control" access to any and all types of IT services. This in turn leads to people clinging on to outdated manual approval processes . While requiring approvals for scarce resources makes sense, insisting that every single request must be manually approved defeats the very purpose of cloud. Not only this causes delays, thereby at least partially negating the agility benefits, it also results in gross inefficiency. In a cloud environment, self-service access should be governed by policies, quotas that the administrators can define upfront . For a cloud initiative to be successful, IT organizations MUST be ready to empower users by giving them real control rather than insisting on brokering every single interaction between users and the cloud resources. Technology: From a technology perspective, cloud is about consolidation, standardization and automation. A consolidated and standardized infrastructure helps increase utilization and reduces cost. Additionally, it enables a much higher degree of automation - thereby providing users the required agility while minimizing operational costs. Obviously, automation is the key to cloud. Unfortunately it hasn’t received as much attention within enterprises as it should have. Many organizations are just now waking up to the criticality of automation and it still often gets relegated to back burner in favor of other "high priority" projects. However, it is important to understand that without the right type and level of automation, cloud will remain a distant dream for most enterprises. This in turn makes the choice of the cloud management software extremely critical. For a cloud management software to be effective in an enterprise environment, it must meet the following qualifications: Broad and Deep Solution It should offer a broad and deep solution to enable the kind of broad-based transformation we are talking about. Its footprint must cover physical and virtual systems, as well as infrastructure, database and application tiers. Too many enterprises choose to equate cloud with virtualization. While virtualization is a critical component of a cloud solution, it is just a component and not the whole solution. Similarly, too many people tend to equate cloud with Infrastructure-as-a-Service (IaaS). While it is perfectly reasonable to treat IaaS as a starting point, it is important to realize that it is just the first stepping stone - and on its own it can only provide limited business benefits. It is actually the higher level services, such as (application) platform and business applications, that will bring about a more meaningful transformation to your enterprise. Run and Manage Efficiently Your Mission Critical Applications It should not only be able to run your mission critical applications, it should do so better than before. For enterprises, applications and data are the critical business assets As such, if you are building a cloud platform that cannot run your ERP application, it isn't truly a "enterprise cloud". Also, be wary of vendors who try to sell you the idea that your applications must be written in a certain way to be able to run on the cloud. That is nothing but a bogus, self-serving argument. For the cloud to be meaningful to enterprises, it should adopt to your applications - and not the other way around. Automated, Integrated Set of Cloud Management Capabilities At the root of many of the problems plaguing enterprise IT today is complexity. A complex maze of tools and technology, coupled with archaic processes, results in an environment which is inflexible, inefficient and simply too hard to manage. Management tool consolidation, therefore, is key to the success of your cloud as tool proliferation adds to complexity, encourages compartmentalization and defeats the very purpose that you are building the cloud for. Decision makers ought to be extra cautious about vendors trying to sell them a "suite" of disparate and loosely integrated products as a cloud solution. An effective enterprise cloud management solution needs to provide a tightly integrated set of capabilities for all aspects of cloud lifecycle management. A simple question to ask: will your environment be more or less complex after you implement your cloud? More often than not, the answer will surprise you. At Oracle, we have understood these challenges and have been working hard to create cloud solutions that are relevant and meaningful for enterprises. And we have been doing it for much longer than you may think. Oracle was one of the very first enterprise software companies to make our products available on the Amazon Cloud. As far back as in 2007, we created new cloud solutions such as Cloud Database Backup that are helping customers like Amazon save millions every year. Our cloud solution portfolio is also the broadest and most deep in the industry - covering public, private, hybrid, Infrastructure, platform and applications clouds. It is no coincidence therefore that the Oracle Cloud today offers the most comprehensive set of public cloud services in the industry. And to a large part, this has been made possible thanks to our years on investment in creating cloud enabling technologies. I will dedicated the third and final part of the blog “Clouds, Clouds Everywhere But not a Drop of Rain” to Oracle Cloud Technologies Building Blocks and how they mapped into our vision of Enterprise Cloud. Stay Tuned.
