• How does rsync --daemon know which way it is being run?

  - by Skaperen

  I am wanting to run rsync over an SSL/TLS encrypted connection. It does not do this directly so I am exploring options. The stunnel program looks promising, although more complicated than designed due to the need to hop connections with the -r option. However, I do find there is a -l option to run a program. I am assuming this works by having two processes, one to carry out the SSL/TLS work, and one to be the worker which the client is communicating to. These would then communicate by a pipe pair or two way socket between them. What struck me as odd when I surveyed a number of web pages to see how to properly set this up is that whether running as a standalone daemon, or under a super daemon like inetd, the arguments for rsync are the same. How does rsync --daemon know whether it should open a socket and listen on it for many connections, or just service one connection by communicating with the stdin/stdout descriptors is has when it starts up (which really would go through the extra process to handle the encryption, description, and SSL/TLS protocol layer)? And then I need to find a way to wrap the client to have it do SSL/TLS in one simple command (as opposed to connection hopping that stunnel seems to favor).

• Multiple Routers, Failover, DHCP and multiple gateways. NOT WAN-failover

  - by u_b

  I've had a look around google and this forum but could not find an answer to my question. So probably one of you can help me a little. My intended setup is: Router R1: wan connection to isp. connected backup server. provides some wireless SSID. other connected devices like printer, laptop, etc. both wired and wireless. Router R2: no wan connection to isp but connected to R2. connects mp3-streamer and music server. also serves as a wireless access point with same SSID. other than described connections only wireless connections. I would like to be able to control music even if R1 is off, e.g. with no internet connection. On the other hand I would like to access internet also in the case that R2 is off, i.e. no music access. Last but not least I would like to stream internet radio, i.e., R1 and R2 are on, and music is streamed from internet to R1 to R2 to streamer. I would like to realize all this using DHCP (also using static assignments) so i do not have to configure statically on android, laptop, etc. So my questions are: Can I make DHCP provide a list of two default gateways R1,R2? In order to make clients fallback to other gateway if currently assigned gateway is turned off? Thanks in advance, u_b

• Why is my server performance degrading to the point of stopping, periodically?

  - by Pascal Aschwanden

  So, once in a while, I see in firebug that a request takes over 15 or even 60 seconds to respond and sometimes never. Here is what I've ruled out: It's not the CPU, cuz every time I check the Server load its less then 6 for all 3 numbers It's not the memory, because thats fairly low too, less the 50% It's not the I/O anymore, because I've seen the graphs that Joyent sent back to me when I requested them, and they show less then 3MB of I/O (mostly all read). It's not the SQL performance - I've profiled every last SQL command that runs, and they're all (99.9% of them anyway) running in less then 30ms, most run in less then 5ms. Oh and I've been profiling all the script execution times, and even the when the problem occurs, the script always manages to finish in 50ms or less (that's 1 / 20th of a second ). Now, I do run alot of ajax calls. 1 every 2 seconds per user and I have 300 DAU+. But, even if all 300 are playing simultaneously, thats still only 150 calls per second max. The only other thing I can think of is that one of my neighbors is funky. The problem is highly intermittent. 99% of the time it works perfectly and there's excellent performance. but 99%+ is not good enough. Eventually the performance gets so bad I have to restart the server, at which point everything is fine again. I've done this about 4 times now. Any ideas? Note: this is on joyent, vps, intro package 256mb of ram with bursting. here are the mysql dump info: Traffic ø per hour Received 18 MiB 29 MiB Sent 134 MiB 221 MiB Total 151 MiB 251 MiB Connections ø per hour % max. concurrent connections 5 --- --- Failed attempts 0 0.00 0.00% Aborted 0 0.00 0.00% Total 9,418 15.59 k 100.00%

• MysqlTunner and query_cache_size dilemma

  On a busy mysql server MySQLTuner 1.2.0 always recommends to add query_cache_size no matter how I increase the value (I tried up to 512MB).

• System With Two Network Adapters [closed]

  - by Synetech inc.

  Hi, My system has a NIC (Marvell Yukon) built-into the motherboard, but I also have a D-Link (RealTek) card. I figure that using the D-Link and disabling the Marvell makes the most sense, though I'm wondering if maybe the built-in one has better throughput (not that my Internet connection is so fast). Also, I'm wondering about the merits of using both at the same time. My router has four ports and I have experimented with enabling and plugging both NICs into the router. I was able to connect to the Internet, but the pattern of usage seemed irregular (which adapter was chosen for the transfer and any given point). I also considered bridging the two, but am having difficulty in finding out what exactly creating network bridge does in the context of the Windows Network Connections window. I am familiar with the concept of connecting networks, so it seems to me that birding two connections on the same segment is pointless at best (and can cause problems like loops?) Does anyone have any tips on what to do if a system has more than one NIC and any clarification on the bridge option? Thanks a lot.

• How do I automatically connect my client to an ODBC data source on another machine with dynamic IP?

  - by Kdansky

  At the customer's place, we've got a postgres DB on a server, and a few clients. We connect them through ODBC-drivers, and all machines run windows (usually XP). Now we had a few annoying issues: The client "forgets" some flags in the ODBC drivers, such as ByteA as LO. Every time anything changes, we have to reset that, and type in the password, and sometimes even the IP of the server. On x64 machines running Windows 7, configuring this is a pain as the system settings dialogue will only show 64-bit connections by default. And most importantly: If the server changes IP because the customer restarts or replaces a switch, all connections are lost. Annoyingly, this cannot be fixed with just correcting the IP, but rather, we have to check every single place (even hba_conf) because all the settings magically disappear. Our customers often are very small companies, where "server" means "that one PC in the other room", and not "Oracle mainframe in the dungeon", so we don't want to rely on them not restarting switches. Is there a better way than to rely on these really unstable settings? Are these settings somewhere in a file which I could edit manually, to make fixing it easier?

• Are there any other causes of this error that are NOT related to initial setup?

  - by LordScree

  I'm trying to diagnose an issue at a customer site. They are receiving the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server I've seen this a few times, but only during the initial setup - it's often caused by one of the following: The database server is turned off The network connection between the database server and the application is closed or somehow blocked (e.g. a firewall) The SQL Server instance is not set up to receive remote connections from the application server (e.g. TCP is turned off, remote connections are disabled, or the "SQL Server Browser" service is stopped/disabled) However, if I assume that no configuration changes have been made, I'm trying to postulate on what the reason might be for getting this error at a random point after the initial setup. My initial thought is: SQL Server machine has run out of resources (e.g. RAM) and is unable to accept new requests from the application server Is this a valid theory? What other possible causes are there of this error that are not related to the initial setup of the server / application connection? Or is it simply impossible that this error could occur without a configuration change having been made (either on the SQL Server side, application side, or somewhere in-between (network))? NOTE: I believe this question differs from the plethora of questions related to this error message because the application and server have been talking to each other quite happily until now (most, if not all, other questions seem to relate to initial setup).

• Log Problem and bash script

  - by GvWorker

  Hello Guys, I have 11 Debian servers running on rackspace cloud hosting. All running VHCS2 for hosting management. 1 server is used for application and 10 are used for only smtp. My question is regarding smtp servers. Each server hosted 1 domain. My problem is when my client use smtp there's a log created in this directory /var/log/ but within 24 hours drives are full and server refuse all smtp connections. Then I deleted the logs and ran following command to check the disk space. df -h but it shows hdd still full and server is still refusing the smtp connections. Then I ran following command to see the truth du --max-depth=1 -h It shows the truth. The real disk space used. Then I rebooted the server and now server working fine. But after few hours same situation happened. Then I created the following script. #!/bin/sh rm -fr /var/log/* rm -fr /var/log/apache2/*.log rm -fr /var/log/apache2/*.log.* rm -fr /var/log/apache2/users/* rm -fr /var/log/apache2/backup/* reboot It worked for days but after that logs are again filling the hdd. Now I want the following solutions. If anybody can help me. When I delete files from server hdd will free up without rebooting Log should be in specific range. Like a specific size of file where old data overwrite with new data

• Is 40+ Logons on Exchange 2003 per user normal?

  - by cbsch

  Hello! We've had a problem at work where users sometimes randomly can't connect to exchange. I've found out that it's because they reached the limit of 32 concurrent logons. I increased the maximum allowed connections by adding the key "Maximum Allowed Sessions Per User" in HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem. But I'm not sure if this is a real good fix. Looking at the logons some users has as many as 15 logons with the exact same logon time. I know for sure that Outlook 2007 does this, as I was watching them while a user connected with Outlook after a restart on the Exchange service. Every user also has an iPhone connected to exchange, I don't know if these cause the same thing. Is this normal? Could there be a bug in the software? (The Outlook 2007 has nothing configured, except added the user, pure vanilla installs). The users are mobile, and when Outlook generates up to 15 connection every time it connects, and I've read (no sources, sorry) that Outlook doesn't time out connections before 2 hours. I might have to set this number real high to prevent it from being a problem.

• How to route outbound traffic to specific domain "XYZ.org" via a specific NIC or public/static IP?

  - by user139943

  Within the next week or so, I'll be setting up an AT&T U-verse modem with 5 usable static public IP addresses. I plan to register a domain name to 1 of the 5 static IPs (remaining 4 unregistered), and run a website from a single server setup in my home LAN. I'll skip the long winded reason why, but I need to somehow route outbound traffic (originating from my server) destined for one public domain (i.e. http://www.sample.org) through one of the UNREGISTERED static IP addresses ONLY. Basically, I want this public domain to see connections coming from an IP address and not my domain name. If it makes it easier, this can apply to all outbound traffic from my server as long as it doesn't impact users browsing my website! Inbound connections should go through the domain name / registered public IP. Can I accomplish this with my single server with one or multiple NICs? Do I need multiple servers and set one up as a proxy? Please help as my background is in software and not networking, and I don't think I can accomplish this at a software level (e.g. Java). Thanks.

• Does Mac OS X throttle the RATE of socket creation?

  - by pbhogan

  This may seem programming related, but this is an OS question. I'm writing a small high performance daemon that takes thousands of connections per second. It's working fine on Linux (specifically Ubuntu 9.10 on EC2). On Mac OS X if I throw a few thousand connections at it (roughly about 16350) in a benchmark that simply opens a connection, does it's thing and closes the connection, then the benchmark program hangs for several seconds waiting for a socket to become available before continuing (or timing out in the process). I used both Apache Bench as well as Siege (to make sure it wasn't the benchmark application). So why/how is Mac OS X limiting the RATE at which sockets can be used, and can I stop it from doing this? Or is there something else going on? I know there is a file descriptor limit, but I'm not hitting that. There is no error on accepting a socket, it's simply hangs for a while after the first (roughly) 16000, waiting -- I assume -- for the OS to release a socket. This shouldn't happen since all prior the sockets are closed at that point. They're supposed to come available at the rate they're closed, and do on Ubuntu, but there seems to be some kind of multi (5-10?) second delay on Mac OS X. I tried tweaking with ulimit every-which-way. Nada.

• Integrating external computer into a domain - some recommendations please

  - by TomTom

  Given: * A multi loation company. Every office has local routers that connect to a central VPN capable rouer in a data center. All fine so far. We now need to move a computer off site into a hosting center across the globe, to get it closer to some supplier computers we work for. it will run limited logic but latency is important, and our latency so far is too large. This computer will be in a data center and does no require incoming connections except for adminsitrative purposes, although it needs outgoing connetions. I have no real chance to put one of my VPN routers there, sadly - otherwise I would have no problem. Usage of RRAs is not recommended (we had various probblems there over time). I could deal with it. The computer MUSt integrate into the corporate structure via VPN and join the domain and be fully "tracked" (controlled for performance). What is the best suggestion? So far it looks like my best bets woudl be to log in via RRAS and deal with whatever issues arise there plus uise the local firewall the limit incoming connections to this computer to what is needed (which runs down to an emergency RDP connection allowance). Anyone a better idea?

• how to throttle http requests on a linux machine?

  - by hooraygradschool

  EDIT: here is the summery: i need to reduce max connections preferably system wide on Ubuntu 11.04 but at least within Google Chrome. i do not need or want to throttle bandwidth, Verizon seems to only care about the number of connections so that is all i want to change. also, i don't want to use firefox unless i have to, i have three other machines all using chrome and synced and i just prefer it over firefox. i use tethering for my home internet connection via my verizon cell phone. without paying for it. this works just fine for streaming netflix via my nintendo wii and pretty much every other conceivable use ive had for it. except, during heavy usage with multiple tabs open on my laptop, the network connection on my phone will just turn off, then on again, then off, but it never fully connects. i think, based on this and other questions that this is caused by verizon getting too many http requests from my phone. is there some software, script, setting or otherwise that would allow me to throttle my requests to say, 5 or 10 or whatever it turns out is 1 less than verizon is looking for, so that my cell's network connection is not lost? i would far prefer a slow down rather than complete shut off of my internet connection. i am almost certain is from quantity of requests and not related to data, because, as i mentioned, netflix will run all day without a hitch, and that uses more data than anything else i would be doing. if i had a router i am pretty sure there are settings i could easily change to only allow so many requests at a time ... but in this case, my phone is my router, so no settings. im using ubuntu 11.04 on my netbook with an htc incredible on verizon (not that the phone details are relevant) i have been trying to figure this out for quite some time, currently the only fix is ensure that all requests are stopped and then sometimes it works again, other times i have to manually turn my 3g service off and then back on. thank you so much for any assistance!

• Our Look at Opera 10.50 Web Browser

  - by Asian Angel

  Everyone has been talking about the newest version of Opera recently but perhaps you have not looked at it too closely yet. Today we will take a look at 10.50 and let you see what this “new browser” is all about. The New Engines Carakan JavaScript Engine: Runs web applications up to 7 times faster than its predecessor Futhark Vega Graphics Library: Enables super fast and smooth graphics on everything from tab switching to webpage animation Presto 2.5: Provides support for HTML5, CSS2.1 and the latest CSS3 standards A Look at the Features Available If you have installed or used older versions of Opera before then the default look after a clean install will probably seem rather different. The main differences in appearance are mainly located within the “glass border” areas of the browser. The “Speed Dial” setup looks and works just as well as in previous versions. You can set a favorite wallpaper or image as your background and choose the number of “dials” using the “Configure Speed Dial Command”. One of the “standout” differences is the “O Button”. All of the menus have been condensed into this single access point but it only takes a few moments to find what you are looking for. If you have used the style before in earlier versions of Opera some of the items have been moved around. For those who prefer the “Menu Bar” that can be easily restored using the “Show Menu Bar Command”. If desired you can actually “extend” the “Tab Bar” downwards to display thumbnails of your open tabs. Just use your mouse to grab the bottom of the “Tab Bar” and adjust it to suit your personal needs. The only problem with this feature is that it will quickly use up a good sized portion of your available UI and browser window space. The “Password Manager” is ready to access when needed…the background for the button will turn a shiny metallic blue when you open a webpage that you have “Login Information” saved for. One of the new features is a small “Recycle Bin Button” in the upper right corner. Clicking on this will display a list of recently closed tabs letting you have easy access to any tabs that you may have accidentally closed. This is definitely a great feature to have as an easy access button. For those who were used to how the “Zoom Feature” looked before it has a new “look” to it. Instead of the pop-up menu-type listing of “view sizes” present before you now have a slider button that you can use to adjust the zooming level. For our default setup here the “Sidebar Panels” available were: “Bookmarks, Widgets, Unite, Notes, Downloads, History, & Panels”. Additional panels such as “Links, Windows, Search, Info, etc.” are available if you want and/or need them (accessible using the “Panels Plus Sign Button”). The “Opera Link Button” makes it easy for you to synchronize your “Speed Dial, Bookmarks, Personal Bar, Custom Searches, History & Notes”. Note: “Opera Link” requires an account and can be signed up for using the link provided below. Want to share files with your family and friends? “Unite” allows you to do that and more. With “Unite” you can: “Stream Music, Show Photo Galleries, Share Files and/or Folders, & host webpages directly from your browser”. We have a more in-depth look at “Unite” in our article here. Note: Use of “Unite” requires an Opera account. Got a slow internet connection? “Opera Turbo” can help with that by running the web traffic through their “compression servers” to speed up your web browsing. Keep in mind that “Opera Turbo” will not engage if you are accessing a secure website (i.e. your bank’s website) thus preserving your security. Note: “Opera Turbo” can be set up to automatically detect slow internet connections (i.e. crowded Wi-Fi in a cafe). Opera has a built-in “Private Browsing Mode” now for those who prefer anonymous browsing and want to keep the “history records clean” on their computer. To access it go to “Tabs and windows” and select “New private tab” or “New private window” as desired. When you open your new “Private Tab or Window” you will see the following message with details on how Opera will handle browsing information and a large “door hanger symbol”. Notice that the one tab is locked into “Private Browsing Mode” while the others are still working in “Regular Browsing Mode”. Very nice! A miniature version of the “door hanger symbol” will be present on any tab that is locked into “Private Browsing Mode”. If you are using Windows 7 then you will love how things look from your “Taskbar”. Here you can see four very nice looking thumbnails for the tabs that we had open. All that you have to do is click on the desired thumbnail… The “Context Menu” looks just as lovely as the thumbnails and definitely has some terrific functionality built into it. Add Enhanced Aero Capability If you love “Aero” and want more for your new Opera install then we have the perfect theme for you. The theme’s name is Z1-AV69 and once you have downloaded it you will need to place it in the “Skins Subfolder” in Opera’s “Program Files Folder”. Note: For our example we used version 1.10 but version 2.00 is now available (link provided below). Once you have restarted Opera, go to the “O Menu” and select “Appearance”. When the “Appearance Window” opens click on “Z1-Glass Skin” and then click “OK”. All of a sudden you will have more “Aero Goodness” to enjoy. Compare this screenshot with the one at the top of this article…the only part that is not transparent now is the browser window area itself. Want even more “Aero Goodness”? Right click on the “Tab Bar” and set “Tab Bar Placement” to “Left”. Note: You can achieve the same effect by setting the “Tab Bar Placement” to “Right”. With the “Speed Dial” visible you will be able to see your wallpaper with ease. While this is obviously not for everyone it does make for a great visual trick. Portable Versions Perhaps you need this wonderful new version of Opera to go with you wherever you do during the day. Not a problem…just visit the Opera USB website to choose a version that works best for you. You can select from “Zip or Exe” setup files and if needed update an older portable version using a “Zipped Update Files Package”. If you are updating an older version keep in mind that you will need to delete the old “OperaUSB.exe. File” due to changes with the new setup files. During our tests updating older portable versions went well for the most part but we did experience a few “odd UI quirks” here and there…so we recommend setting up a clean install if possible. Conclusion The new 10.50 release is a pleasure to use and is a recommended install for your system. Whether you are considering trying Opera for the first time or have been using it for a bit we think that you will pleased with everything that the 10.50 release has to offer.

• Stream Music and Video Over the Internet with Windows Media Player 12

  - by DigitalGeekery

  A new feature in Windows Media Player 12, which is included with Windows 7, is being able to stream media over the web to other Windows 7 computers.  Today we will take a look at how to set it up and what you need to begin. Note: You will need to perform this process on each computer that you want to use. What You’ll Need Two computers running Windows 7 Home Premium, Professional, or Ultimate. The host, or home computer that you will be streaming the media from, cannot be on a public network or part of domain. Windows Live ID UPnP or Port Forwarding enabled on your home router Media files added to your Windows Media Player library Windows Live ID Sign up online for a Windows Live ID if you do not already have one. See the link below for a link to Windows Live.   Configuring the Windows 7 Computers Open Windows Media Player and go to the library section. Click on Stream and then “Allow Internet access to home media.”   The Internet Home Media Access pop up window will prompt you to link your Windows Live ID to a user account. Click “Link an online ID.” If you haven’t already installed the Windows Live ID Sign-In Assistant, you will be taken to Microsoft’s website and prompted to download it. Once you have completed the Windows Live download assistant install, you will see Windows Live ID online provider appear in the “Link Online IDs” window. Click on “Link Online ID.” Next, you’ll be prompted for a Windows Live ID and password. Enter your Windows Live ID and password and click “Sign In.” A pop up window will notify you that you have successfully allowed Internet access to home media. Now, you will have to repeat the exact same configuration on the 2nd Windows 7 computer. Once you have completed the same configuration on your 2nd computer, you might also need to configure your home router for port forwarding. If your router supports UPnP, you may not need to manually forward any ports on your router. So, this would be a good time to test your connection. Go to a nearby hotspot, or perhaps a neighbor’s house, and test to see if you can stream your media. If not, you’ll need to manually forward the ports. You can always choose to forward the ports anyway, just in case. Note: We tested on a Linksys WRT54GL router, which supports UPnP, and found we still needed to manually forward the ports. Finding the ports to forward on the router Open Windows Media Player and make sure you are in Library view. Click on “Stream” on the top menu, and select “Allow Internet access to home media.”   On the “Internet Home Media Access” window, click on “Diagnose connections.” The “Internet Streaming Diagnostic Tool” will pop up. Click on “Port forwarding information” near the bottom.   On the “Port Forwarding Information” window you will find both the Internal and External Port numbers you will need to forward on your router. The Internal port number should always be 10245. The external number will be different depending on your computer. Microsoft also recommends forwarding port 443. Configuring the Router Next, you’ll need to configure Port Forwarding on your home router. We will show you the steps for a Linksys WRT54GL router, however, the steps for port forwarding will vary from router to router. On the Linksys configuration page, click on the Administration Tab along the top, click the “Applications & Gaming Tab, and then the “Port Range Forward” tab below it. Under “Application,” type in a name. It can be any name you choose. In both the “Start” and “End” boxes, type the port number. Enter the IP address of your home computer in the IP address column. Click the check box under “Enable.” Do this for both the internal and external port numbers and port 443. When finished, click the “Save Settings” button. Note: It’s highly recommended that you configure your home computer with a static IP address When you’re ready to play your media over the Internet, open up Windows Media Player and look for your host computer and username listed under “Other Libraries.” Click on it expand the list to see your media libraries. Choose a library and a file to play. Now you can enjoy your streaming media over the Internet. Conclusion We found media streaming over the Internet to work fairly well. However, we did see a loss of quality with streaming video. Also, Recorded TV .wtv and dvr-ms files did not play at all. Check out our previous article to see how to stream media share and stream media between Windows 7 computers on your home network.

• The new workflow management of Oracle´s Hyperion Planning: Define more details with Planning Unit Hierarchies and Promotional Paths

  - by Alexandra Georgescu

  After having been almost unchanged for several years, starting with the 11.1.2 release of Oracle´s Hyperion Planning the Process Management has not only got a new name: “Approvals” now is offering the possibility to further split Planning Units (comprised of a unique Scenario-Version-Entity combination) into more detailed combinations along additional secondary dimensions, a so called Planning Unit Hierarchy, and also to pre-define a path of planners, reviewers and approvers, called Promotional Path. I´d like to introduce you to changes and enhancements in this new process management and arouse your curiosity for checking out more details on it. One reason of using the former process management in Planning was to limit data entry rights to one person at a time based on the assignment of a planning unit. So the lowest level of granularity for this assignment was, for a given Scenario-Version combination, the individual entity. Even if in many cases one person wasn´t responsible for all data being entered into that entity, but for only part of it, it was not possible to split the ownership along another additional dimension, for example by assigning ownership to different accounts at the same time. By defining a so called Planning Unit Hierarchy (PUH) in Approvals this gap is now closed. Complementing new Shared Services roles for Planning have been created in order to manage set up and use of Approvals: The Approvals Administrator consisting of the following roles: Approvals Ownership Assigner, who assigns owners and reviewers to planning units for which Write access is assigned (including Planner responsibilities). Approvals Supervisor, who stops and starts planning units and takes any action on planning units for which Write access is assigned. Approvals Process Designer, who can modify planning unit hierarchy secondary dimensions and entity members for which Write access is assigned, can also modify scenarios and versions that are assigned to planning unit hierarchies and can edit validation rules on data forms for which access is assigned. (this includes as well Planner and Ownership Assigner responsibilities) Set up of a Planning Unit Hierarchy is done under the Administration menu, by selecting Approvals, then Planning Unit Hierarchy. Here you create new PUH´s or edit existing ones. The following window displays: After providing a name and an optional description, a pre-selection of entities can be made for which the PUH will be defined. Available options are: All, which pre-selects all entities to be included for the definitions on the subsequent tabs None, manual entity selections will be made subsequently Custom, which offers the selection for an ancestor and the relative generations, that should be included for further definitions. Finally a pattern needs to be selected, which will determine the general flow of ownership: Free-form, uses the flow/assignment of ownerships according to Planning releases prior to 11.1.2 In Bottom-up, data input is done at the leaf member level. Ownership follows the hierarchy of approval along the entity dimension, including refinements using a secondary dimension in the PUH, amended by defined additional reviewers in the promotional path. Distributed, uses data input at the leaf level, while ownership starts at the top level and then is distributed down the organizational hierarchy (entities). After ownership reaches the lower levels, budgets are submitted back to the top through the approval process. Proceeding to the next step, now a secondary dimension and the respective members from that dimension might be selected, in order to create more detailed combinations underneath each entity. After selecting the Dimension and a Parent Member, the definition of a Relative Generation below this member assists in populating the field for Selected Members, while the Count column shows the number of selected members. For refining this list, you might click on the icon right beside the selected member field and use the check-boxes in the appearing list for deselecting members. -------------------------------------------------------------------------------------------------------- TIP: In order to reduce maintenance of the PUH due to changes in the dimensions included (members added, moved or removed) you should consider to dynamically link those dimensions in the PUH with the dimension hierarchies in the planning application. For secondary dimensions this is done using the check-boxes in the Auto Include column. For the primary dimension, the respective selection criteria is applied by right-clicking the name of an entity activated as planning unit, then selecting an item of the shown list of include or exclude options (children, descendants, etc.). Anyway in order to apply dimension changes impacting the PUH a synchronization must be run. If this is really necessary or not is shown on the first screen after selecting from the menu Administration, then Approvals, then Planning Unit Hierarchy: under Synchronized you find the statuses Yes, No or Locked, where the last one indicates, that another user is just changing or synchronizing the PUH. Select one of the not synchronized PUH´s (status No) and click the Synchronize option in order to execute. -------------------------------------------------------------------------------------------------------- In the next step owners and reviewers are assigned to the PUH. Using the icons with the magnifying glass right besides the columns for Owner and Reviewer the respective assignments can be made in the ordermthat you want them to review the planning unit. While it is possible to assign only one owner per entity or combination of entity+ member of the secondary dimension, the selection for reviewers might consist of more than one person. The complete Promotional Path, including the defined owners and reviewers for the entity parents, can be shown by clicking the icon. In addition optional users might be defined for being notified about promotions for a planning unit. -------------------------------------------------------------------------------------------------------- TIP: Reviewers cannot change data, but can only review data according to their data access permissions and reject or promote planning units. -------------------------------------------------------------------------------------------------------- In order to complete your PUH definitions click Finish - this saves the PUH and closes the window. As a final step, before starting the approvals process, you need to assign the PUH to the Scenario-Version combination for which it should be used. From the Administration menu select Approvals, then Scenario and Version Assignment. Expand the PUH in order to see already existing assignments. Under Actions click the add icon and select scenarios and versions to be assigned. If needed, click the remove icon in order to delete entries. After these steps, set up is completed for starting the approvals process. Start, stop and control of the approvals process is now done under the Tools menu, and then Manage Approvals. The new PUH feature is complemented by various additional settings and features; some of them at least should be mentioned here: Export/Import of PUHs: Out of Office agent: Validation Rules changing promotional/approval path if violated (including the use of User-defined Attributes (UDAs)): And various new and helpful reviewer actions with corresponding approval states.

• Integrating Flickr with ASP.Net application

  - by sreejukg

  Flickr is the popular photo management and sharing application offered by yahoo. The services from flicker allow you to store and share photos and videos online. Flicker offers strong API support for almost all services they provide. Using this API, developers can integrate photos to their public website. Since 2005, developers have collaborated on top of Flickr's APIs to build fun, creative, and gorgeous experiences around photos that extend beyond Flickr. In this article I am going to demonstrate how easily you can bring the photos stored on flicker to your website. Let me explain the scenario this article is trying to address. I have a flicker account where I upload photos and share in many ways offered by Flickr. Now I have a public website, instead of re-upload the photos again to public website, I want to show this from Flickr. Also I need complete control over what photo to display. So I went and referred the Flickr documentation and there is API support ready to address my scenario (and more… ). FlickerAPI for ASP.Net To Integrate Flicker with ASP.Net applications, there is a library available in CodePlex. You can find it here http://flickrnet.codeplex.com/ Visit the URL and download the latest version. The download includes a Zip file, when you unzip you will get a number of dlls. Since I am going to use ASP.Net application, I need FlickrNet.dll. See the screenshot of all the dlls, and there is a help file available in the download (.chm) for your reference. Once you have the dll, you need to use Flickr API from your website. I assume you have a flicker account and you are familiar with Flicker services. Arrange your photos using Sets in Flickr In flicker, you can define sets and add your uploaded photos to sets. You can compare set to photo album. A set is a logical collection of photos, which is an excellent option for you to categorize your photos. Typically you will have a number of sets each set having few photos. You can write application that brings photos from sets to your website. For the purpose of this article I already created a set Flickr and added some photos to it. Once you logged in to Flickr, you can see the Sets under the Menu. In the Sets page, you will see all the sets you have created. As you notice, you can see certain sample images I have uploaded just to test the functionality. Though I wish I couldn’t create good photos so please bear with me. I have created 2 photo sets named Blue Album and Red Album. Click on the image for the set, will take you to the corresponding set page. In the set “Red Album” there are 4 photos and the set has a unique ID (highlighted in the URL). You can simply retrieve the photos with the set id from your application. In this article I am going to retrieve the images from Red album in my ASP.Net page. For that First I need to setup FlickrAPI for my usage. Configure Flickr API Key As I mentioned, we are going to use Flickr API to retrieve the photos stored in Flickr. In order to get access to Flickr API, you need an API key. To create an API key, navigate to the URL http://www.flickr.com/services/apps/create/ Click on Request an API key link, now you need to tell Flickr whether your application in commercial or non-commercial. I have selected a non-commercial key. Now you need to enter certain information about your application. Once you enter the details, Click on the submit button. Now Flickr will create the API key for your application. Generating non-commercial API key is very easy, in couple of steps the key will be generated and you can use the key in your application immediately. ASP.Net application for retrieving photos Now we need write an ASP.Net application that display pictures from Flickr. Create an empty web application (I named this as FlickerIntegration) and add a reference to FlickerNet.dll. Add a web form page to the application where you will retrieve and display photos(I have named this as Gallery.aspx). After doing all these, the solution explorer will look similar to following. I have used the below code in the Gallery.aspx page. The output for the above code is as follows. I am going to explain the code line by line here. First it is adding a reference to the FlickrNet namespace. using FlickrNet; Then create a Flickr object by using your API key. Flickr f = new Flickr("<yourAPIKey>"); Now when you retrieve photos, you can decide what all fields you need to retrieve from Flickr. Every photo in Flickr contains lots of information. Retrieving all will affect the performance. For the demonstration purpose, I have retrieved all the available fields as follows. PhotoSearchExtras.All But if you want to specify the fields you can use logical OR operator(|). For e.g. the following statement will retrieve owner name and date taken. PhotoSearchExtras extraInfo = PhotoSearchExtras.OwnerName | PhotoSearchExtras.DateTaken; Then retrieve all the photos from a photo set using PhotoSetsGetPhotos method. I have passed the PhotoSearchExtras object created earlier. PhotosetPhotoCollection photos = f.PhotosetsGetPhotos("72157629872940852", extraInfo); The PhotoSetsGetPhotos method will return a collection of Photo objects. You can just navigate through the collection using a foreach statement. foreach (Photo p in photos) {     //access each photo properties } Photo class have lot of properties that map with the properties from Flickr. The chm documentation comes along with the CodePlex download is a great asset for you to understand the fields. In the above code I just used the following p.LargeUrl – retrieves the large image url for the photo. p.ThumbnailUrl – retrieves the thumbnail url for the photo p.Title – retrieves the Title of the photo p.DateUploaded – retrieves the date of upload Visual Studio intellisense will give you all properties, so it is easy, you can just try with Visual Studio intellisense to find the right properties you are looking for. Most of hem are self-explanatory. So you can try retrieving the required properties. In the above code, I just pushed the photos to the page. In real time you can use the retrieved photos along with JQuery libraries to create animated photo galleries, slideshows etc. Configuration and Troubleshooting If you get access denied error while executing the code, you need to disable the caching in Flickr API. FlickrNet cache the photos to your local disk when retrieved. You can specify a cache folder where the application need write permission. You can specify the Cache folder in the code as follows. Flickr.CacheLocation = Server.MapPath("./FlickerCache/"); If the application doesn’t have have write permission to the cache folder, the application will throw access denied error. If you cannot give write permission to the cache folder, then you must disable the caching. You can do this from code as follows. Flickr.CacheDisabled = true; Disabling cache will have an impact on the performance. Take care! Also you can define the Flickr settings in web.config file.You can find the documentation here. http://flickrnet.codeplex.com/wikipage?title=ExampleConfigFile&ProjectName=flickrnet Flickr is a great place for storing and sharing photos. The API access allows developers to do seamless integration with the photos uploaded on Flickr.

• It's not just “Single Sign-on” by Steve Knott (aurionPro SENA)

  - by Greg Jensen

  It is true that Oracle Enterprise Single Sign-on (Oracle ESSO) started out as purely an application single sign-on tool but as we have seen in the previous articles in this series the product has matured into a suite of tools that can do more than just automated single sign-on and can also provide rapidly deployed, cost effective solution to many demanding password management problems. In the last article of this series I would like to discuss three cases where customers faced password scenarios that required more than just single sign-on and how some of the less well known tools in the Oracle ESSO suite “kitbag” helped solve these challenges. Case #1 One of the issues often faced by our customers is how to keep their applications compliant. I had a client who liked the idea of automated single sign-on for most of his applications but had a key requirement to actually increase the security for one specific SOX application. For the SOX application he wanted to secure access by using two-factor authentication with a smartcard. The problem was that the application did not support two-factor authentication. The solution was to use a feature from the Oracle ESSO suite called authentication manager. This feature enables you to have multiple authentication methods for the same user which in this case was a smartcard and the Windows password.  Within authentication manager each authenticator can be configured with a security grade so we gave the smartcard a high grade and the Windows password a normal grade. Security grading in Oracle ESSO can be configured on a per application basis so we set the SOX application to require the higher grade smartcard authenticator. The end result for the user was that they enjoyed automated single sign-on for most of the applications apart from the SOX application. When the SOX application was launched, the user was required by ESSO to present their smartcard before being given access to the application. Case #2 Another example solving compliance issues was in the case of a large energy company who had a number of core billing applications. New regulations required that users change their password regularly and use a complex password. The problem facing the customer was that the core billing applications did not have any native user password change functionality. The customer could not replace the core applications because of the cost and time required to re-develop them. With a reputation for innovation aurionPro SENA were approached to provide a solution to this problem using Oracle ESSO. Oracle ESSO has a password expiry feature that can be triggered periodically based on the timestamp of the users’ last password creation therefore our strategy here was to leverage this feature to provide the password change experience. The trigger can launch an application change password event however in this scenario there was no native change password feature that could be launched therefore a “dummy” change password screen was created that could imitate the missing change password function and connect to the application database on behalf of the user. Oracle ESSO was configured to trigger a change password event every 60 days. After this period if the user launched the application Oracle ESSO would detect the logon screen and invoke the password expiry feature. Oracle ESSO would trigger the “dummy screen,” detect it automatically as the application change password screen and insert a complex password on behalf of the user. After the password event had completed the user was logged on to the application with their new password. All this was provided at a fraction of the cost of re-developing the core applications. Case #3 Recent popular initiatives such as the BYOD and working from home schemes bring with them many challenges in administering “unmanaged machines” and sometimes “unmanageable users.” In a recent case, a client had a dispersed community of casual contractors who worked for the business using their own laptops to access applications. To improve security the around password management the security goal was to provision the passwords directly to these contractors. In a previous article we saw how Oracle ESSO has the capability to provision passwords through Provisioning Gateway but the challenge in this scenario was how to get the Oracle ESSO agent to the casual contractor on an unmanaged machine. The answer was to use another tool in the suite, Oracle ESSO Anywhere. This component can compile the normal Oracle ESSO functionality into a deployment package that can be made available from a website in a similar way to a streamed application. The ESSO Anywhere agent does not actually install into the registry or program files but runs in a folder within the user’s profile therefore no local administrator rights are required for installation. The ESSO Anywhere package can also be configured to stay persistent or disable itself at the end of the user’s session. In this case the user just needed to be told where the website package was located and download the package. Once the download was complete the agent started automatically and the user was provided with single sign-on to their applications without ever knowing the application passwords. Finally, as we have seen in these series Oracle ESSO not only has great utilities in its own tool box but also has direct integration with Oracle Privileged Account Manager, Oracle Identity Manager and Oracle Access Manager. Integrated together with these tools provides a complete and complementary platform to address even the most complex identity and access management requirements. So what next for Oracle ESSO? “Agentless ESSO available in the cloud” – but that will be a subject for a future Oracle ESSO series!

• Java FAQ: Tudo o que você precisa saber

  - by Bruno.Borges

  Com frequência recebo e-mails de clientes com dúvidas sobre "quando sairá a próxima versão do Java?", ou então "quando vai expirar o Java?" ou ainda "quais as mudanças da próxima versão?". Por isso resolvi escrever aqui um FAQ, respondendo estas dúvidas e muitas outras. Este post estará sempre atualizado, então se você possui alguma dúvida, envie para mim no Twitter @brunoborges. Qual a diferença entre o Oracle JDK e o OpenJDK?O projeto OpenJDK funciona como a implementação de referência Open Source do Java Standard Edition. Empresas como a Oracle, IBM, e Azul Systems suportam e investem no projeto OpenJDK para continuar evoluindo a plataforma Java. O Oracle JDK é baseado no OpenJDK, mas traz outras ferramentas como o Mission Control, e a máquina virtual traz algumas features avançadas como por exemplo o Flight Recorder. Até a versão 6, a Oracle oferecia duas máquinas virtuais: JRockit (BEA) e HotSpot (Sun). A partir da versão 7 a Oracle unificou as máquinas virtuais, e levou as features avançadas do JRockit para dentro da VM HotSpot. Leia também o OpenJDK FAQ. Onde posso obter binários beta Early Access do JDK 7, JDK 8, JDK 9 para testar?A partir do projeto OpenJDK, existe um projeto específico para cada versão do Java. Nestes projetos você pode encontrar binários beta Early Access, além do código-fonte. JDK 6 - http://jdk6.java.net/ JDK 7 - http://jdk7.java.net/ JDK 8 - http://jdk8.java.net/ JDK 9 - http://jdk9.java.net/ Quando acaba o suporte do Oracle Java SE 6, 7, 8? Somente produtos e versões com release oficial são suportados pela Oracle (exemplo: não há suporte para binários beta do JDK 7, JDK 8, ou JDK 9). Existem duas categorias de datas que o usuriário do Java deve estar ciente:  EOPU - End of Public UpdatesMomento em que a Oracle não mais disponibiliza publicamente atualizações Oracle SupportPolítica de suporte da Oracle para produtos, incluindo o Oracle Java SE O Oracle Java SE é um produto e portando os períodos de suporte são regidos pelo Oracle Lifetime Support Policy. Consulte este documento para datas atualizadas e específicas para cada versão do Java. O Oracle Java SE 6 já atingiu EOPU (End of Public Updates) e agora é mantido e atualizado somente para clientes através de contrato comercial de suporte. Para maiores informações, consulte a página sobre Oracle Java SE Support.  O mais importante aqui é você estar ciente sobre as datas de EOPU para as versões do Java SE da Oracle.Consulte a página do Oracle Java SE Support Roadmap e busque nesta página pela tabela com nome Java SE Public Updates. Nela você encontrará a data em que determinada versão do Java irá atingir EOPU. Como funciona o versionamento do Java?Em 2013, a Oracle divulgou um novo esquema de versionamento do Java para facilmente identificar quando é um release CPU e quando é um release LFR, e também para facilitar o planejamento e desenvolvimento de correções e features para futuras versões. CPU - Critical Patch UpdateAtualizações com correções de segurança. Versão será múltipla de 5, ou com soma de 1 para manter o número ímpar. Exemplos: 7u45, 7u51, 7u55. LFR - Limited Feature ReleaseAtualizações com correções de funcionalidade, melhorias de performance, e novos recursos. Versões de números pares múltiplos de 20, com final 0. Exemplos: 7u40, 7u60, 8u20. Qual a data da próxima atualização de segurança (CPU) do Java SE?Lançamentos do tipo CPU são controlados e pré-agendados pela Oracle e se aplicam a todos os produtos, inclusive o Oracle Java SE. Estes releases acontecem a cada 3 meses, sempre na Terça-feira mais próxima do dia 17 dos meses de Janeiro, Abril, Julho, e Outubro. Consulte a página Critical Patch Updates, Security Alerts and Third Party Bulleting para saber das próximas datas. Caso tenha interesse, você pode acompanhar através de recebimentos destes boletins diretamente no seu email. Veja como assinar o Boletim de Segurança da Oracle. Qual a data da próxima atualização de features (LFR) do Java SE?A Oracle reserva o direito de não divulgar estas datas, assim como o faz para todos os seus produtos. Entretanto é possível acompanhar o desenvolvimento da próxima versão pelos sites do projeto OpenJDK. A próxima versão do JDK 7 será o update 60 e binários beta Early Access já estão disponíveis para testes. A próxima versão doJDK 8 será o update 20 e binários beta Early Access já estão disponíveis para testes. Onde posso ver as mudanças e o que foi corrigido para a próxima versão do Java?A Oracle disponibiliza um changelog para cada binário beta Early Access divulgado no portal Java.net. JDK 7 update 60 changelogs JDK 8 update 20 changelogs Quando o Java da minha máquina (ou do meu usuário) vai expirar?Conheçendo o sistema de versionamento do Java e a periodicidade dos releases de CPU, o usuário pode determinar quando que um update do Java irá expirar. De todo modo, a cada novo update, a Oracle já informa quando que este update deverá expirar diretamente no release notes da versão. Por exemplo, no release notes da versão Oracle Java SE 7 update 55, está escrito na seção JRE Expiration Date o seguinte: The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 7u55) will expire with the release of the next critical patch update scheduled for July 15, 2014. For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u55) on August 15, 2014. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.Ou seja, a versão 7u55 irá expirar com o lançamento do próximo release CPU, pré-agendado para o dia 15 de Julho de 2014. E caso o computador do usuário não possa se comunicar com o servidor da Oracle, esta versão irá expirar forçadamente no dia 15 de Agosto de 2014 (através de um mecanismo embutido na versão 7u55). O usuário não é obrigado a atualizar para versões LFR e portanto, mesmo com o release da versão 7u60, a versão atual 7u55 não irá expirar.Veja o release notes do Oracle Java SE 8 update 5. Encontrei um bug. Como posso reportar bugs ou problemas no Java SE, para a Oracle?Sempre que possível, faça testes com os binários beta antes da versão final ser lançada. Qualquer problema que você encontrar com estes binários beta, por favor descreva o problema através do fórum de Project Feebdack do JDK.Caso você encontre algum problema em uma versão final do Java, utilize o formulário de Bug Report. Importante: bugs reportados por estes sistemas não são considerados Suporte e portanto não há SLA de atendimento. A Oracle reserva o direito de manter o bug público ou privado, e também de informar ou não o usuário sobre o progresso da resolução do problema. Tenho uma dúvida que não foi respondida aqui. Como faço?Se você possui uma pergunta que não foi respondida aqui, envie para bruno.borges_at_oracle.com e caso ela seja pertinente, tentarei responder neste artigo.

• Easier ASP.NET MVC Routing

  - by Steve Wilkes

  I've recently refactored the way Routes are declared in an ASP.NET MVC application I'm working on, and I wanted to share part of the system I came up with; a really easy way to declare and keep track of ASP.NET MVC Routes, which then allows you to find the name of the Route which has been selected for the current request. Traditional MVC Route Declaration Traditionally, ASP.NET MVC Routes are added to the application's RouteCollection using overloads of the RouteCollection.MapRoute() method; for example, this is the standard way the default Route which matches /controller/action URLs is created: routes.MapRoute(     "Default",     "{controller}/{action}/{id}",     new { controller = "Home", action = "Index", id = UrlParameter.Optional }); The first argument declares that this Route is to be named 'Default', the second specifies the Route's URL pattern, and the third contains the URL pattern segments' default values. To then write a link to a URL which matches the default Route in a View, you can use the HtmlHelper.RouteLink() method, like this: @ this.Html.RouteLink("Default", new { controller = "Orders", action = "Index" }) ...that substitutes 'Orders' into the {controller} segment of the default Route's URL pattern, and 'Index' into the {action} segment. The {Id} segment was declared optional and isn't specified here. That's about the most basic thing you can do with MVC routing, and I already have reservations: I've duplicated the magic string "Default" between the Route declaration and the use of RouteLink(). This isn't likely to cause a problem for the default Route, but once you get to dozens of Routes the duplication is a pain. There's no easy way to get from the RouteLink() method call to the declaration of the Route itself, so getting the names of the Route's URL parameters correct requires some effort. The call to MapRoute() is quite verbose; with dozens of Routes this gets pretty ugly. If at some point during a request I want to find out the name of the Route has been matched.... and I can't. To get around these issues, I wanted to achieve the following: Make declaring a Route very easy, using as little code as possible. Introduce a direct link between where a Route is declared, where the Route is defined and where the Route's name is used, so I can use Visual Studio's Go To Definition to get from a call to RouteLink() to the declaration of the Route I'm using, making it easier to make sure I use the correct URL parameters. Create a way to access the currently-selected Route's name during the execution of a request. My first step was to come up with a quick and easy syntax for declaring Routes. 1 . An Easy Route Declaration Syntax I figured the easiest way of declaring a route was to put all the information in a single string with a special syntax. For example, the default MVC route would be declared like this: "{controller:Home}/{action:Index}/{Id}*" This contains the same information as the regular way of defining a Route, but is far more compact: The default values for each URL segment are specified in a colon-separated section after the segment name The {Id} segment is declared as optional simply by placing a * after it That's the default route - a pretty simple example - so how about this? routes.MapRoute(     "CustomerOrderList",     "Orders/{customerRef}/{pageNo}",     new { controller = "Orders", action = "List", pageNo = UrlParameter.Optional },     new { customerRef = "^[a-zA-Z0-9]+$", pageNo = "^[0-9]+$" }); This maps to the List action on the Orders controller URLs which: Start with the string Orders/ Then have a {customerRef} set of characters and numbers Then optionally a numeric {pageNo}. And again, it’s quite verbose. Here's my alternative: "Orders/{customerRef:^[a-zA-Z0-9]+$}/{pageNo:^[0-9]+$}*->Orders/List" Quite a bit more brief, and again, containing the same information as the regular way of declaring Routes: Regular expression constraints are declared after the colon separator, the same as default values The target controller and action are specified after the -> The {pageNo} is defined as optional by placing a * after it With an appropriate parser that gave me a nice, compact and clear way to declare routes. Next I wanted to have a single place where Routes were declared and accessed. 2. A Central Place to Declare and Access Routes I wanted all my Routes declared in one, dedicated place, which I would also use for Route names when calling RouteLink(). With this in mind I made a single class named Routes with a series of public, constant fields, each one relating to a particular Route. With this done, I figured a good place to actually declare each Route was in an attribute on the field defining the Route’s name; the attribute would parse the Route definition string and make the resulting Route object available as a property. I then made the Routes class examine its own fields during its static setup, and cache all the attribute-created Route objects in an internal Dictionary. Finally I made Routes use that cache to register the Routes when requested, and to access them later when required. So the Routes class declares its named Routes like this: public static class Routes{     [RouteDefinition("Orders/{customerName}->Orders/Index")]     public const string OrdersCustomerIndex = "OrdersCustomerIndex";     [RouteDefinition("Orders/{customerName}/{orderId:^([0-9]+)$}->Orders/Details")]     public const string OrdersDetails = "OrdersDetails";     [RouteDefinition("{controller:Home}*/{action:Index}*")]     public const string Default = "Default"; } ...which are then used like this: @ this.Html.RouteLink(Routes.Default, new { controller = "Orders", action = "Index" }) Now that using Go To Definition on the Routes.Default constant takes me to where the Route is actually defined, it's nice and easy to quickly check on the parameter names when using RouteLink(). Finally, I wanted to be able to access the name of the current Route during a request. 3. Recovering the Route Name The RouteDefinitionAttribute creates a NamedRoute class; a simple derivative of Route, but with a Name property. When the Routes class examines its fields and caches all the defined Routes, it has access to the name of the Route through the name of the field against which it is defined. It was therefore a pretty easy matter to have Routes give NamedRoute its name when it creates its cache of Routes. This means that the Route which is found in RequestContext.RouteData.Route is now a NamedRoute, and I can recover the Route's name during a request. For visibility, I made NamedRoute.ToString() return the Route name and URL pattern, like this: The screenshot is from an example project I’ve made on bitbucket; it contains all the named route classes and an MVC 3 application which demonstrates their use. I’ve found this way of defining and using Routes much tidier than the default MVC system, and you find it useful too

• Portal And Content - Content Integration - Best Practices

  - by Stefan Krantz

  Lately we have seen an increase in projects that have failed to either get user friendly content integration or non satisfactory performance. Our intention is to mitigate any knowledge gap that our previous post might have left you with, therefore this post will repeat some recommendation or reference back to old useful post. Moreover this post will help you understand ground up how to design, architect and implement business enabled, responsive and performing portals with complex requirements on business centric information publishing. Design the Information Model The key to successful portal deployments is Information modeling, it's a key task to understand the use case you designing for, therefore I have designed a set of question you need to ask yourself or your customer: Question: Who will own the content, IT or Business? Answer: BusinessQuestion: Who will publish the content, IT or Business? Answer: BusinessQuestion: Will there be multiple publishers? Answer: YesQuestion: Are the publishers computer scientist?Answer: NoQuestion: How often do the information changes, daily, weekly, monthly?Answer: Daily, weekly If your answers to the questions matches at least 2, we strongly recommend you design your content with following principles: Divide your pages in to logical sections, where each section is marked with its purpose Assign capabilities to each section, does it contain text, images, formatting and/or is it static and is populated through other contextual information Select editor/design element type WYSIWYG - Rich Text Plain Text - non-format text Image - Image object Static List - static list of formatted informationDynamic Data List - assembled information from multiple data files through CMIS query The result of such design map could look like following below examples: Based on the outcome of the required elements in the design column 3 from the left you will now simply design a data model in WebCenter Content - Site Studio by creating a Region Definition structure matching your design requirements.For more information on how to create a Region definition see following post: Region Definition Post - note see instruction 7 for details. Each region definition can now be used to instantiate data files, a data file will hold the actual data for each element in the region definition. Another way you can see this is to compare the region definition as an extension to the metadata model in WebCenter Content for each data file item. Design content templates With a solid dependable information model we can now proceed to template creation and page design, in this phase focuses on how to place the content sections from the region definition on the page via a Content Presenter template. Remember by creating content presenter templates you will leverage the latest and most integrated technology WebCenter has to offer. This phase is much easier since the you already have the information model and design wire-frames to base the logic on, however there is still few considerations to pay attention to: Base the template on ADF and make only necessary exceptions to markup when required Leverage ADF design components for Tabs, Accordions and other similar components, this way the design in the content published areas will comply with other design areas based on custom ADF taskflows There is no performance impact when using meta data or region definition based data All data access regardless of type, metadata or xml data it can be accessed via the Content Presenter - Node. See below for applied examples on how to access data Access metadata property from Document - #{node.propertyMap['myProp'].value}myProp in this example can be for instance (dDocName, dDocTitle, xComments or any other available metadata) Access element data from data file xml - #{node.propertyMap['[Region Definition Name]:[Element name]'].asTextHtml}Region Definition Name is the expect region definition that the current data file is instantiatingElement name is the element value you like to grab from the data file I recommend you read following  useful post on content template topic:CMIS queries and template creation - note see instruction 9 for detailsStatic List template rendering For more information on templates:Single Item Content TemplateMulti Item Content TemplateExpression Language Internationalization Considerations When integrating content assets via content presenter you by now probably understand that the content item/data file is wired to the page, what is also pretty common at this stage is that the content item/data file only support one language since its not practical or business friendly to mix that into a complex structure. Therefore you will be left with a very common dilemma that you will have to either build a complete new portal for each locale, which is not an good option! However with little bit of information modeling and clear naming convention this can be addressed. Basically you can simply make sure that all content item/data file are named with a predictable naming convention like "Content1_EN" for the English rendition and "Content1_ES" for the Spanish rendition. This way through simple none complex customizations you will be able to dynamically switch the actual content item/data file just before rendering. By following proposed approach above you not only enable a simple mechanism for internationalized content you also preserve the functionality in the content presenter to support business accessible run-time publishing of information on existing and new pages. I recommend you read following useful post on Internationalization topics:Internationalize with Content Presenter Integrate with Review & Approval processes Today the Review and approval functionality and configuration is based out of WebCenter Content - Criteria Workflows. Criteria Workflows uses the metadata of the checked in document to evaluate if the document is under any review/approval process. So for instance if a Criteria Workflow is configured to force any documents with Version = "2" or "higher" and Content Type is "Instructions", any matching content item version on check in will now enter the workflow before getting released for general access. Few things to consider when configuring Criteria Workflows: Make sure to not trigger on version one for Content Items that are Data Files - if you trigger on version 1 you will not only approve an empty document you will also have a content presenter pointing to a none existing document - since the document will only be available after successful completion of the workflow Approval workflows sometimes requires more complex criteria, the recommendation if that is the case is that the meta data triggering such criteria is automatically populated, this can be achieved through many approaches including Content Profiles Criteria workflows are configured and managed in WebCenter Content Administration Applets where you can configure one or more workflows. When you configured Criteria workflows the Content Presenter will support the editors with the approval process directly inline in the "Contribution mode" of the portal. In addition to approve/reject and details of the task, the content presenter natively support the user to view the current and future version of the change he/she is approving. See below for example: Architectural recommendation To support review&approval processes - minimize the amount of data files per page Each CMIS query can consume significant time depending on the complexity of the query - minimize the amount of CMIS queries per page Use Content Presenter Templates based on ADF - this way you minimize the design considerations and optimize the usage of caching Implement the page in as few Data files as possible - simplifies publishing process, increases performance and simplifies release process Named data file (node) or list of named nodes when integrating to pages increases performance vs. querying for data Named data file (node) or list of named nodes when integrating to pages enables business centric page creation and publishing and reduces the need for IT department interaction Summary Just because one architectural decision solves a business problem it doesn't mean its the right one, when designing portals all architecture has to be in harmony and not impacting each other. For instance the most technical complex solution is not always the best since it will most likely defeat the business accessibility, performance or both, therefore the best approach is to first design for simplicity that even a non-technical user can operate, after that consider the performance impact and final look at the technology challenges these brings and workaround them first with out-of-the-box features, after that design and develop functions to complement the short comings.

• Accessing SharePoint 2010 Data with REST/OData on Windows Phone 7

  - by Jan Tielens

  Consuming SharePoint 2010 data in Windows Phone 7 applications using the CTP version of the developer tools is quite a challenge. The issue is that the SharePoint 2010 data is not anonymously available; users need to authenticate to be able to access the data. When I first tried to access SharePoint 2010 data from my first Hello-World-type Windows Phone 7 application I thought “Hey, this should be easy!” because Windows Phone 7 development based on Silverlight and SharePoint 2010 has a Client Object Model for Silverlight. Unfortunately you can’t use the Client Object Model of SharePoint 2010 on the Windows Phone platform; there’s a reference to an assembly that’s not available (System.Windows.Browser). My second thought was “OK, no problem!” because SharePoint 2010 also exposes a REST/OData API to access SharePoint data. Using the REST API in SharePoint 2010 is as easy as making a web request for a URL (in which you specify the data you’d like to retrieve), e.g. http://yoursiteurl/_vti_bin/listdata.svc/Announcements. This is very easy to accomplish in a Silverlight application that’s running in the context of a page in a SharePoint site, because the credentials of the currently logged on user are automatically picked up and passed to the WCF service. But a Windows Phone application is of course running outside of the SharePoint site’s page, so the application should build credentials that have to be passed to SharePoint’s WCF service. This turns out to be a small challenge in Silverlight 3, the WebClient doesn’t support authentication; there is a Credentials property but when you set it and make the request you get a NotImplementedException exception. Probably this issued will be solved in the very near future, since Silverlight 4 does support authentication, and there’s already a WCF Data Services download that uses this new platform feature of Silverlight 4. So when Windows Phone platform switches to Silverlight 4, you can just use the WebClient to get the data. Even more, if the OData Client Library for Windows Phone 7 gets updated after that, things should get even easier! By the way: the things I’m writing in this paragraph are just assumptions that I make which make a lot of sense IMHO, I don’t have any info all of this will happen, but I really hope so. So are SharePoint developers out of the Windows Phone development game until they get this fixed? Well luckily not, when the HttpWebRequest class is being used instead, you can pass credentials! Using the HttpWebRequest class is slightly more complex than using the WebClient class, but the end result is that you have access to your precious SharePoint 2010 data. The following code snippet is getting all the announcements of an Annoucements list in a SharePoint site: HttpWebRequest webReq =     (HttpWebRequest)HttpWebRequest.Create("http://yoursite/_vti_bin/listdata.svc/Announcements");webReq.Credentials = new NetworkCredential("username", "password"); webReq.BeginGetResponse(    (result) => {        HttpWebRequest asyncReq = (HttpWebRequest)result.AsyncState;         XDocument xdoc = XDocument.Load(            ((HttpWebResponse)asyncReq.EndGetResponse(result)).GetResponseStream());         XNamespace ns = "http://www.w3.org/2005/Atom";        var items = from item in xdoc.Root.Elements(ns + "entry")                    select new { Title = item.Element(ns + "title").Value };         this.Dispatcher.BeginInvoke(() =>        {            foreach (var item in items)                MessageBox.Show(item.Title);        });    }, webReq); When you try this in a Windows Phone 7 application, make sure you add a reference to the System.Xml.Linq assembly, because the code uses Linq to XML to parse the resulting Atom feed, so the Title of every announcement is being displayed in a MessageBox. Check out my previous post if you’d like to see a more polished sample Windows Phone 7 application that displays SharePoint 2010 data.When you plan to use this technique, it’s of course a good idea to encapsulate the code doing the request, so it becomes really easy to get the data that you need. In the following code snippet you can find the GetAtomFeed method that gets the contents of any Atom feed, even if you need to authenticate to get access to the feed. delegate void GetAtomFeedCallback(Stream responseStream); public MainPage(){    InitializeComponent();     SupportedOrientations = SupportedPageOrientation.Portrait |         SupportedPageOrientation.Landscape;     string url = "http://yoursite/_vti_bin/listdata.svc/Announcements";    string username = "username";    string password = "password";    string domain = "";     GetAtomFeed(url, username, password, domain, (s) =>    {        XNamespace ns = "http://www.w3.org/2005/Atom";        XDocument xdoc = XDocument.Load(s);         var items = from item in xdoc.Root.Elements(ns + "entry")                    select new { Title = item.Element(ns + "title").Value };         this.Dispatcher.BeginInvoke(() =>        {            foreach (var item in items)            {                MessageBox.Show(item.Title);            }        });    });} private static void GetAtomFeed(string url, string username,     string password, string domain, GetAtomFeedCallback cb){    HttpWebRequest webReq = (HttpWebRequest)HttpWebRequest.Create(url);    webReq.Credentials = new NetworkCredential(username, password, domain);     webReq.BeginGetResponse(        (result) =>        {            HttpWebRequest asyncReq = (HttpWebRequest)result.AsyncState;            HttpWebResponse resp = (HttpWebResponse)asyncReq.EndGetResponse(result);            cb(resp.GetResponseStream());        }, webReq);}
