• How to Collect Debug Info for Oracle SQL Developer

  - by thatjeffsmith

  In a perfect world, there would be no software bugs. Developers would always test their code. QA would find any scenarios and bugs the developers hadn’t already thought of. Regression tests would be complete and flawless. But alas, we can only afford to pay mere humans here, so we will have bugs from time to time. Or sometimes you are trying to do something the software wasn’t designed for, or perhaps your machine has exhausted it’s resources trying to build the un-buildable. When you run into problems, you will need help. Developers need your help so they can help you. Surprisingly enough, feedback like this isn’t very helpful: Your program isn’t working. How can I make it work? When you are ready to work with us on the SQL Developer OTN forum, you will most likely be asked to run SQL Developer and capture the output from the command console. In case you need help with this, ere’s a step-by-step process you can follow in Windows 7 (should work in XP too.) Open a windows command window Start – Run – CMD Once it’s open, click on the window icon and select ‘Defaults.’ Change the default buffer size to be something bigger, much bigger. Set the CMD window default buffer size HIGHER Note: you only need to do this once. Navigate to your SQL Developer Installation Folder Instead of running the ‘sqldeveloper.exe’ file in the root directory, we are going to go several sub-directories down. Find the ‘bin’ sub-directory and run the ‘sqldeveloper.exe’ there. When you do this, a CMD window will open, and then you’ll see the SQL Developer application load. The SQL Developer bin directory - run the tool from here and get a logging window Use SQL Developer as normal, until it ‘breaks’ or ‘hangs’ Now, you are ready to grab the nitty-gritty information that MIGHT tell the developer what is going wrong or happening in your scenario. Click back into the CMD window Send a Ctrl+Break or a Ctrl+Pause. If you on a newer laptop that doesn’t have this key, be sure to check the ‘Fn’ subset of keys. If you need to map the BREAK or PAUSE buttons, this article might help. You can also try the on-screen keyboard in windows – just type ‘OSK’ in your START – RUN prompt. Copy the logging information from the command window – all of it We need this information, help us get it! Open a case with Oracle Support or Start a Thread on the Forums Or email me. If you’re on my blog reading this, it’s the least I can do to help Now, before you hit ‘Send’ or ‘Post’ or ‘Submit’ – be sure to add a brief description of what you were doing in the application when you ran into the problem. Even if you were doing ‘nothing,’ let us know how many connections you had open, what windows were active, etc. The more you can tell us, the higher your odds go up to getting a quick fix or at least an answer as to what is happening. Also include the following information: The version of SQL Developer you are running The version of the JDK you are using The OS you are using The version of Oracle you are connected to Now, don’t be surprised if you get asked to upgrade to a supported configuration, say ‘version 3.1 and the 1.6 JDK.’ Supporting older versions of software is fun, and while we enjoy a challenge, it may be easier for you to upgrade your way out of the problem at hand.

• CQRS &ndash; Questions and Concerns

  - by Dylan Smith

  I’ve been doing a lot of learning on CQRS and Event Sourcing over the last little while and I have a number of questions that I haven’t been able to answer. 1. What is the benefit of CQRS when compared to a typical DDD architecture that uses Event Sourcing and properly captures intent and behavior via verb-based commands? (other than Scalability) 2. When using CQRS what do you do with complex query-based logic? I’m going to elaborate on #1 in this blog post and I’ll do a follow-up post on #2. I watched through Greg Young’s video on the business benefits of CQRS + Event Sourcing and first let me say that I thought it was an excellent presentation that really drives home a lot of the benefits to this approach to architecture (I watched it twice in a row I enjoyed it so much!). But it didn’t answer some of my questions fully (I wish I had been there to ask these of Greg in person!). So let me pick apart some of the points he makes and how they relate to my first question above. I’m completely sold on the idea of event sourcing and have a clear understanding of the benefits that it brings to the table, so I’m not going to question that. But you can use event sourcing without going to a CQRS architecture, so my main question is around the benefits of CQRS + Event Sourcing vs Event Sourcing + Typical DDD architecture Architecture with Event Sourcing + Commands on Left, CQRS on Right Greg talks about how the stereotypical architecture doesn’t support DDD, but is that only because his diagram shows DTO’s coming up from the client. If we use the same diagram but allow the client to send commands doesn’t that remove a lot of the arguments that Greg makes against the stereotypical architecture? We can now introduce verbs into the system. We can capture intent now (storing it still requires event sourcing, but you can implement event sourcing without doing CQRS) We can create a rich domain model (as opposed to an anemic domain model) Scalability is obviously a benefit that CQRS brings to the table, but like Greg says, very few of the systems we create truly need significant scalability Greg talks about the ability to scale your development efforts. He says CQRS allows you to split the system into 3 parts (Client, Domain/Commands, Reads) and assign 3 teams of developers to work on them in parallel; letting you scale your development efforts by 3x with nearly linear gains. But in the stereotypical architecture don’t you already have 2 separate modules that you can split your dev efforts between: The client that sends commands/queries and receives DTO’s, and the Domain which accepts commands/queries, and generates events/DTO’s. If this is true it’s not really a 3x scaling you achieve with CQRS but merely a 1.5x scaling which while great doesn’t sound nearly as dramatic (“I can do it with 10 devs in 12 months – let me hire 5 more and we can have it done in 8 months”). Making the Query side “stupid simple” such that you can assign junior developers (or even outsource it) sounds like a valid benefit, but I have some concerns over what you do with complex query-based logic/behavior. I’m going to go into more detail on this in a follow-up blog post shortly. He also seemed to focus on how “stupid-simple” it is doing queries against the de-normalized data store, but I imagine there is still significant complexity in the event handlers that interpret the events and apply them to the de-normalized tables. It sounds like Greg suggests that because we’re doing CQRS that allows us to apply Event Sourcing when we otherwise wouldn’t be able to (~33:30 in the video). I don’t believe this is true. I don’t see why you wouldn’t be able to apply Event Sourcing without separating out the Commands and Queries. The queries would just operate against the domain model instead of the database. But you’d still get the benefits of Event Sourcing. Without CQRS the queries would only be able to operate against the current state rather than the event history, but even in CQRS the domain behaviors can only operate against the current state and I don’t see that being a big limiting factor. If some query needs to operate against something that is not captured by the current state you would just have to update the domain model to capture that information (no different than if that statement were made about a Command under CQRS). Some of the benefits I do see being applicable are that your domain model might end up being simpler/smaller since it only needs to represent the state needed to process commands and not worry about the reads (like the Deactivate Inventory Item and associated comment example that Greg provides). And also commands that can be handled in a Transaction Script style manner by the command handler simply generating events and not touching the domain model. It also makes it easier for your senior developers to focus on the command behavior and ignore the queries, which is usually going to be a better use of their time. And of course scalability. If anybody out there has any thoughts on this and can help educate me further, please either leave a comment or feel free to get in touch with me via email:

• How to Get All the Windows 8 Editions on One Install Disk

  - by Taylor Gibb

  There are a lot of different versions of Windows, but you probably didn’t know that short of the Enterprise edition, the disc or image that you own contains all versions for that architecture. Read on to see how we can use them to make a universal Windows 8 install disc. Things You Will Need A x86 Version of Windows 8 A x64 Version of Windows 8 A x86 Version of Windows 8 Enterprise A x64 Version of Windows 8 Enterprise A Windows 8 PC Note: While we will use all the images above you don’t really need the Enterprise Edition. You could always leave out parts of the tutorial if you know what you are doing, if you are not comfortable with that and still want to follow through you could always grab the Enterprise evaluation images that are available for free to the public, on MSDN. Getting Started To get started you will need to Download the Windows 8 ADK from Microsoft. Once downloaded go ahead and install it, you will only need the Deployment tools so be sure to uncheck the rest of the options. Lastly you will also need to create the following folder structure on the root of your C:\ drive to make things a bit easier. C:\Windows8Root C:\Windows8Root\x86 C:\Windows8Root\x64 C:\Windows8Root\Enterprisex86 C:\Windows8Root\Enterprisex64 C:\Windows8Root\Temp C:\Windows8Root\Final OK lets get started. Making The Image The first thing we need to do is create a base image, so mount the x86 version of Windows 8 and copy its files to: C:\Windows8Root\Final Now move the install.wim file from: C:\Windows8Root\Final\sources To: C:\Windows8Root\x86 Next go ahead and copy the install.wim file from the other 3 images, Windows 8 x64, Windows 8 Enterprise x86 and Windows 8 Enterprise x64 to the respective folders in Windows8Root, the install.wim file can be located at: D:\sources\install.wim Note: The above assumes that the images are always mounted at drive D. Remember that each install.wim is different so don’t copy them to the wrong directories or the rest of the tutorial wont work. Next switch to the Metro Start Screen and open the Deployment and Imaging Tools Environment. Note: If you are not a local administrator on your PC, you will need to right-click on it and choose to run it as an administrator. Now run the following commands: Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:2 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8″ /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro with Media Center” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\Enterprisex86\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Enterprise” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:2 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8″ /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\x64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Pro with Media Center” /compress:maximum Dism /Export-Image /SourceImageFile:c:\Windows8Root\Enterprisex64\install.wim /SourceIndex:1 /DestinationImageFile:c:\Windows8Root\Final\sources\install.wim /DestinationName:”Windows 8 Enterprise” /compress:maximum Next navigate to: C:\Windows8Root\sources\ And create a new text file. You will need to call it: EI.cfg Then edit it to look like the following: The last thing we need to do is work some magic to get Windows Media Center added to the WMC editions of Windows 8. For that I have written a little script to make it easier for everybody, you can grab it here. Once you have downloaded it extract it. In order to use it right-click in the bottom left hand corner of the screen, and open an elevated command prompt. Then go ahead and paste the following into the command prompt window. powershell.exe -ExecutionPolicy Unrestricted -File C:\Users\Taylor\Documents\HTGWindows8Converter.ps1 Note: You will need to replace the path to the script, another thing to note is that if the path you replace it with has spaces you will need to enclose the path in quotes. The script should kick off straight away and has some progress bars you can watch while it does its thing. Half way through another Window will pop open, which will start creating your final ISO image. When its complete, close the command prompt and you should have an ISO image on the root of your C drive called: HTGWindows8.iso That’s all there is to it. 7 Ways To Free Up Hard Disk Space On Windows HTG Explains: How System Restore Works in Windows HTG Explains: How Antivirus Software Works

• Browsing Your ADF Application Module Pooling Params with WLST

  - by Duncan Mills

  In ADF 11g you can of course use Enterprise Manager (EM) to browse and configure the settings used by ADF Business Components  Application Modules, as shown here for one of my sample deployed applications. This screen you can access from the EM homepage by pulling down the Application Deployment menu, and then ADF > Configure ADF Business Components. Then select the profile that you are actually using (Hint: look in the DataBindings.cpx file to work this out - probably the "Local" version unless you've explicitly changed it. )So, from this screen you can change the pooling parameters and the world is good. But what if you don't have EM installed? In that case you can use the WebLogic scripting capabilities to view (and Update) the MBean Properties. Explanation The pooling parameters and many others are handled through Message Driven Beans that are created for the deployed application in the server. In the case of the ADF BC pooling parameters, this MBean will combine the configuration deployed as part of the application, along with any overrides defined as -D environement commands on the JVM startup for the application server instance. Using WLST to Browse the Bean ValuesFor our purposes here I'm doing this interactively, although you can also write a script or write Java to achieve the same thing.Step 0: Before You Start You will need the followingAccess to the console on the machine that is running the serverThe WebLogic Admin username and password (I'll use weblogic/password as my example here - yours will be different)The name of the deployed application (in this example FMWdh_application1)The package path to the bc4j.xcfg file (in this example oracle.demo.fmwdh.model.service.common.bc4j.xcfg) This is based on the default path for your model project so it shoudl be fairly easy to work out.The BC configuration your AM is actually running with (look in the DataBindings.cpx for that. In this example DealHelpServiceDeployed is the profile being used..)Step 1: Start the WLST consoleTo start at the beginning, you need to run the WLST command but that needs a little setup:Change to the wlserver_10.3/server/bin directory e.g. under your Fusion Middleware Home[oracle@mymachine] cd /home/oracle/FMW_R1/wlserver_10.3/server/binSet your environment using the setWLSEnv script. e.g. on Oracle Enterprise Linux:[oracle@mymachine bin] source setWLSEnv.shStart the WLST interactive console[oracle@mymachine bin] java weblogic.WLSTInitializing WebLogic Scripting Tool (WLST) ...Welcome to WebLogic Server Administration Scripting ShellType help() for help on available commandswls:/offline> Step 2:Enter the WLST commandsConnect to the server wls:> connect('weblogic','password')Change to the Custom root, this is where the AMPooling MBeans are registered wls:> custom()Change to the b4j MBean directorywls:> cd ('oracle.bc4j.mbean.config')Work out the correct directory for the AM configuration you need. This is the difficult bit, not because it's hard to do, but because the names are long. The structure here is such that every child MBean is displayed at the same level as the parent, so for each deployed application there will be many directories shown. In fact, do an ls() command here and you'll see what I mean. Each application will have one MBean for the app as a whole, and then for each deployed configuration in the .xcfg file you'll see: One for the config entry itself, and then one each for Security, DB Connection and AM Pooling. So if you deploy an app with just one configuration you'll see 5 directories, if it has two configurations in the .xcfg you'll see 9 and so on.The directory you are looking for will contain those bits of information you gathered in Step 0, specifically the Application Name, the configuration you are using and the xcfg name: First of all narrow your list to just those directories returned from the ls() command that begin oracle.bc4j.mbean.config:name=AMPool. These identify the AM pooling MBeans for all the deployed applications. Now look for the correct application name e.g. Application=FMWdh_application1The config setting in that sub-list should already be correct and match what you expect e.g. oracle.bc4j.mbean.config=oracle.demo.fmwdh.model.service.common.bc4j.xcfgFinally look for the correct value for the AppModuleConfigType e.g. oracle.bc4j.mbean.config.AppModuleConfigType=DealHelpServiceDeployedNow you have identified the correct directory name, change to that (keep the name on one line of course - I've had to split it across lines here for clarity:wls:> cd ('oracle.bc4j.mbean.config:name=AMPool,     type=oracle.bc4j.mbean.config.AppModuleConfigType.AMPoolType,    oracle.bc4j.mbean.config=oracle.demo.fmwdh.model.service.common.bc4j.xcfg,    Application=FMWdh_application1,    oracle.bc4j.mbean.config.AppModuleConfigType=DealHelpServiceDeployed') Now you can actually view the parameter values with a simple ls() commandwls:> ls()And here's the output in which you can view the realtime values of the various pool settings: -rw- AmpoolConnectionstrategyclass oracle.jbo.common.ampool.DefaultConnectionStrategy -rw- AmpoolDoampooling true -rw- AmpoolDynamicjdbccredentials false -rw- AmpoolInitpoolsize 2 -rw- AmpoolIsuseexclusive true -rw- AmpoolMaxavailablesize 40 -rw- AmpoolMaxinactiveage 600000 -rw- AmpoolMaxpoolsize 4096 -rw- AmpoolMinavailablesize 2 -rw- AmpoolMonitorsleepinterval 600000 -rw- AmpoolResetnontransactionalstate true -rw- AmpoolSessioncookiefactoryclass oracle.jbo.common.ampool.DefaultSessionCookieFactory -rw- AmpoolTimetolive 3600000 -rw- AmpoolWritecookietoclient false -r-- ConfigMBean true -rw- ConnectionPoolManager oracle.jbo.server.ConnectionPoolManagerImpl -rw- Doconnectionpooling false -rw- Dofailover false -rw- Initpoolsize 0 -rw- Maxpoolcookieage -1 -rw- Maxpoolsize 4096 -rw- Poolmaxavailablesize 25 -rw- Poolmaxinactiveage 600000 -rw- Poolminavailablesize 5 -rw- Poolmonitorsleepinterval 600000 -rw- Poolrequesttimeout 30000 -rw- Pooltimetolive -1 -r-- ReadOnly false -rw- Recyclethreshold 10 -r-- RestartNeeded false -r-- SystemMBean false -r-- eventProvider true -r-- eventTypes java.lang.String[jmx.attribute.change] -r-- objectName oracle.bc4j.mbean.config:name=AMPool,type=oracle.bc4j.mbean.config.AppModuleConfigType.AMPoolType,oracle.bc4j.mbean.config=oracle.demo.fmwdh.model.service.common.bc4j.xcfg,Application=FMWdh_application1,oracle.bc4j.mbean.config.AppModuleConfigType=DealHelpServiceDeployed -rw- poolClassName oracle.jbo.common.ampool.ApplicationPoolImpl Thanks to Brian Fry on the JDeveloper PM Team who did most of the work to put this sequence of steps together with me badgering him over his shoulder.

• Make a Drive Image Using an Ubuntu Live CD

  - by Trevor Bekolay

  Cloning a hard drive is useful, but what if you have to make several copies, or you just want to make a complete backup of a hard drive? Drive images let you put everything, and we mean everything, from your hard drive in one big file. With an Ubuntu Live CD, this is a simple process – the versatile tool dd can do this for us right out of the box. We’ve used dd to clone a hard drive before. Making a drive image is very similar, except instead of copying data from one hard drive to another, we copy from a hard drive to a file. Drive images are more flexible, as you can do what you please with the data once you’ve pulled it off the source drive. Your drive image is going to be a big file, depending on the size of your source drive – dd will copy every bit of it, even if there’s only one tiny file stored on the whole hard drive. So, to start, make sure you have a device connected to your computer that will be large enough to hold the drive image. Some ideas for places to store the drive image, and how to connect to them in an Ubuntu Live CD, can be found at this previous Live CD article. In this article, we’re going to make an image of a 1GB drive, and store it on another hard drive in the same PC. Note: always be cautious when using dd, as it’s very easy to completely wipe out a drive, as we will show later in this article. Creating a Drive Image Boot up into the Ubuntu Live CD environment. Since we’re going to store the drive image on a local hard drive, we first have to mount it. Click on Places and then the location that you want to store the image on – in our case, a 136GB internal drive. Open a terminal window (Applications > Accessories > Terminal) and navigate to the newly mounted drive. All mounted drives should be in /media, so we’ll use the command cd /media and then type the first few letters of our difficult-to-type drive, press tab to auto-complete the name, and switch to that directory. If you wish to place the drive image in a specific folder, then navigate to it now. We’ll just place our drive image in the root of our mounted drive. The next step is to determine the identifier for the drive you want to make an image of. In the terminal window, type in the command sudo fdisk -l Our 1GB drive is /dev/sda, so we make a note of that. Now we’ll use dd to make the image. The invocation is sudo dd if=/dev/sda of=./OldHD.img This means that we want to copy from the input file (“if”) /dev/sda (our source drive) to the output file (“of”) OldHD.img, which is located in the current working directory (that’s the “.” portion of the “of” string). It takes some time, but our image has been created…Let’s test to make sure it works. Drive Image Testing: Wiping the Drive Another interesting thing that dd can do is totally wipe out the data on a drive (a process we’ve covered before). The command for that is sudo dd if=/dev/urandom of=/dev/sda This takes some random data as input, and outputs it to our drive, /dev/sda. If we examine the drive now using sudo fdisk –l, we can see that the drive is, indeed, wiped. Drive Image Testing: Restoring the Drive Image We can restore our drive image with a call to dd that’s very similar to how we created the image. The only difference is that the image is going to be out input file, and the drive now our output file. The exact invocation is sudo dd if=./OldHD.img of=/dev/sda It takes a while, but when it’s finished, we can confirm with sudo fdisk –l that our drive is back to the way it used to be! Conclusion There are a lots of reasons to create a drive image, with backup being the most obvious. Fortunately, with dd creating a drive image only takes one line in a terminal window – if you’ve got an Ubuntu Live CD handy!

• CQRS - Benefits

  - by Dylan Smith

  Thanks to all the comments and feedback from the last post I think I have a better understanding now of the benefits of CQRS (separate from the benefits of Event Sourcing). I’m going to try and sum it up here, and point out some areas where I could still use some advice: CQRS Benefits Sounds like the primary benefit of CQRS as an architecture is it allows you to create a simpler domain model by sucking out everything related to queries. I can definitely see the benefit to this, in general the domain logic related to commands is the high-value behavior in the software, but the logic required to service the queries would add a lot of low-value “noise” to the domain model that would dilute the high-value (command) behavior – sorting, paging, filtering, pre-fetch paths, etc. Also the most appropriate domain structure for implementing commands might not be the most optimal for implementing queries. To paraphrase Greg, this usually results in a domain model that is mediocre at both, piss-poor at one, or more likely piss-poor at both commands and queries. Not only will you be able to simplify your domain model by pulling out all the query logic, but at least a handful of commands in most systems will probably be “pass-though” type commands with little to no logic that just generate events. If these can be implemented directly in the command-handler and never touch the domain model, this allows you to slim down the domain model even more. Also, if you were to do event sourcing without CQRS, you no longer have a database containing the current state (only the domain model would) which makes it difficult (or impossible) to support ad-hoc querying and/or reporting that is common in most business software. Of course CQRS provides some great scalability benefits, not only scalability but I have to assume that it provides extremely low latency for most operations, especially if you have an asynchronous event bus. I know Greg says that you get a 3x scaling (Commands, Queries, Client) of your ability to perform parallel development, but IMHO, it seems like it only provides 1.5x scaling since even without CQRS you’re going to have your client loosely coupled to your domain - which is still a great benefit to be able to realize. Questions / Concerns If all the queries against an aggregate get pulled out to the Query layer, what if the only commands for that aggregate can be handled in a “pass-through” manner with the command handler directly generating events. Is it possible to have an aggregate that isn’t modeled in the domain model? Are there any issues or downsides to this? I know in the feedback from my previous posts it was suggested that having one domain model handling both commands and queries requires implementing a lot of traversals between objects that wouldn’t be necessary if it was only servicing commands. My question is, do you include traversals in your domain model based on the needs of the code, or based on the conceptual domain model? If none of my Commands require a Customer.Orders traversal, but the conceptual domain includes the concept of a set of orders belonging to a customer – should I model that in my domain model or not? I like the idea of using the Query side of the architecture as a place to put junior devs where the risk of them screwing something up has minimal impact. But I’m not sold on the idea that you can actually outsource it. Like I said in one of my comments on my previous post, the code to handle a query and generate DTO’s is going to be dead simple, but the code to process events and apply them to the tables on the query side is going to require a significant amount of domain knowledge to know which events to listen for to update each of the de-normalized tables (and what changes need to be made when each event is processed). I don’t know about everybody else, but having Indian/Russian/whatever outsourced developers have to do anything that requires significant domain knowledge has never been successful in my experience. And if you need to spec out for each new query which events to listen to and what to do with each one, well that’s probably going to be just as much work to document as it would be to just implement it. Greg made the point in a comment that doing an aggregate query like “Total Sales By Customer” is going to be inefficient if you use event sourcing but not CQRS. I don’t understand why that would be the case. I imagine in that case you’d simply have a method/property on the Customer object that calculated total sales for that customer by enumerating over the Orders collection. Then the application services layer would generate DTO’s off of the Customers collection that included say the CustomerID, CustomerName, TotalSales, or whatever the case may be. As long as you use a snapshotting implementation, I don’t see why that would be anymore inefficient in a DDD+Event Sourcing implementation than in a typical DDD implementation. Like I mentioned in my last post I still have some questions about query logic that haven’t been answered yet, but before I start asking those I want to make sure I have a strong grasp on what benefits CQRS provides.  My main concern with the query logic was that I know I could just toss it all into the query side, but I was concerned that I would be losing the benefits of using CQRS in the first place if I did that.  I want to elaborate more on this though with some example situations in an upcoming post.

• Lync Server 2010

  - by ManojDhobale

  Microsoft Lync Server 2010 communications software and its client software, such as Microsoft Lync 2010, enable your users to connect in new ways and to stay connected, regardless of their physical location. Lync 2010 and Lync Server 2010 bring together the different ways that people communicate in a single client interface, are deployed as a unified platform, and are administered through a single management infrastructure. Workload Description IM and presence Instant messaging (IM) and presence help your users find and communicate with one another efficiently and effectively. IM provides an instant messaging platform with conversation history, and supports public IM connectivity with users of public IM networks such as MSN/Windows Live, Yahoo!, and AOL. Presence establishes and displays a user’s personal availability and willingness to communicate through the use of common states such as Available or Busy. This rich presence information enables other users to immediately make effective communication choices. Conferencing Lync Server includes support for IM conferencing, audio conferencing, web conferencing, video conferencing, and application sharing, for both scheduled and impromptu meetings. All these meeting types are supported with a single client. Lync Server also supports dial-in conferencing so that users of public switched telephone network (PSTN) phones can participate in the audio portion of conferences. Conferences can seamlessly change and grow in real time. For example, a single conference can start as just instant messages between a few users, and escalate to an audio conference with desktop sharing and a larger audience instantly, easily, and without interrupting the conversation flow. Enterprise Voice Enterprise Voice is the Voice over Internet Protocol (VoIP) offering in Lync Server 2010. It delivers a voice option to enhance or replace traditional private branch exchange (PBX) systems. In addition to the complete telephony capabilities of an IP PBX, Enterprise Voice is integrated with rich presence, IM, collaboration, and meetings. Features such as call answer, hold, resume, transfer, forward and divert are supported directly, while personalized speed dialing keys are replaced by Contacts lists, and automatic intercom is replaced with IM. Enterprise Voice supports high availability through call admission control (CAC), branch office survivability, and extended options for data resiliency. Support for remote users You can provide full Lync Server functionality for users who are currently outside your organization’s firewalls by deploying servers called Edge Servers to provide a connection for these remote users. These remote users can connect to conferences by using a personal computer with Lync 2010 installed, the phone, or a web interface. Deploying Edge Servers also enables you to federate with partner or vendor organizations. A federated relationship enables your users to put federated users on their Contacts lists, exchange presence information and instant messages with these users, and invite them to audio calls, video calls, and conferences. Integration with other products Lync Server integrates with several other products to provide additional benefits to your users and administrators. Meeting tools are integrated into Outlook 2010 to enable organizers to schedule a meeting or start an impromptu conference with a single click and make it just as easy for attendees to join. Presence information is integrated into Outlook 2010 and SharePoint 2010. Exchange Unified Messaging (UM) provides several integration features. Users can see if they have new voice mail within Lync 2010. They can click a play button in the Outlook message to hear the audio voice mail, or view a transcription of the voice mail in the notification message. Simple deployment To help you plan and deploy your servers and clients, Lync Server provides the Microsoft Lync Server 2010, Planning Tool and the Topology Builder. Lync Server 2010, Planning Tool is a wizard that interactively asks you a series of questions about your organization, the Lync Server features you want to enable, and your capacity planning needs. Then, it creates a recommended deployment topology based on your answers, and produces several forms of output to aid your planning and installation. Topology Builder is an installation component of Lync Server 2010. You use Topology Builder to create, adjust and publish your planned topology. It also validates your topology before you begin server installations. When you install Lync Server on individual servers, the installation program deploys the server as directed in the topology. Simple management After you deploy Lync Server, it offers the following powerful and streamlined management tools: Active Directory for its user information, which eliminates the need for separate user and policy databases. Microsoft Lync Server 2010 Control Panel, a new web-based graphical user interface for administrators. With this web-based UI, Lync Server administrators can manage their systems from anywhere on the corporate network, without needing specialized management software installed on their computers. Lync Server Management Shell command-line management tool, which is based on the Windows PowerShell command-line interface. It provides a rich command set for administration of all aspects of the product, and enables Lync Server administrators to automate repetitive tasks using a familiar tool. While the IM and presence features are automatically installed in every Lync Server deployment, you can choose whether to deploy conferencing, Enterprise Voice, and remote user access, to tailor your deployment to your organization’s needs.

• How to Sync Any Folder With SkyDrive on Windows 8.1

  - by Chris Hoffman

  Before Windows 8.1, it was possible to sync any folder on your computer with SkyDrive using symbolic links. This method no longer works now that SkyDrive is baked into Windows 8.1, but there are other tricks you can use. Creating a symbolic link or directory junction inside your SkyDrive folder will give you an empty folder in your SkyDrive cloud storage. Confusingly, the files will appear inside the SkyDrive Modern app as if they were being synced, but they aren’t. The Solution With SkyDrive refusing to understand and accept symbolic links in its own folder, the best option is probably to use symbolic links anyway — but in reverse. For example, let’s say you have a program that automatically saves important data to a folder anywhere on your hard drive — whether it’s C:\Users\USER\Documents\, C:\Program\Data, or anywhere else. Rather than trying to trick SkyDrive into understanding a symbolic link, we could instead move the actual folder itself to SkyDrive and then use a symbolic link at the folder’s original location to trick the original program. This may not work for every single program out there. But it will likely work for most programs, which use standard Windows API calls to access folders and save files. We’re just flipping the old solution here — we can’t trick SkyDrive anymore, so let’s try to trick other programs instead. Moving a Folder and Creating a Symbolic Link First, ensure no program is using the external folder. For example, if it’s a program data or settings folder, close the program that’s using the folder. Next, simply move the folder to your SkyDrive folder. Right-click the external folder, select Cut, go to the SkyDrive folder, right-click and select Paste. The folder will now be located in the SkyDrive folder itself, so it will sync normally. Next, open a Command Prompt window as Administrator. Right-click the Start button on the taskbar or press Windows Key + X and select Command Prompt (Administrator) to open it. Run the following command to create a symbolic link at the original location of the folder: mklink /d “C:\Original\Folder\Location” “C:\Users\NAME\SkyDrive\FOLDERNAME\” Enter the correct paths for the exact location of the original folder and the current location of the folder in your SkyDrive. Windows will then create a symbolic link at the folder’s original location. Most programs should hopefully be tricked by this symbolic location, saving their files directly to SkyDrive. You can test this yourself. Put a file into the folder at its original location. It will be saved to SkyDrive and sync normally, appearing in your SkyDrive storage online. One downside here is that you won’t be able to save a file onto SkyDrive without it taking up space on the same hard drive SkyDrive is on. You won’t be able to scatter folders across multiple hard drives and sync them all. However, you could always change the location of the SkyDrive folder on Windows 8.1 and put it on a drive with a larger amount of free space. To do this, right-click the SkyDrive folder in File Explorer, select Properties, and use the options on the Location tab. You could even use Storage Spaces to combine the drives into one larger drive. Automatically Copy the Original Files to SkyDrive Another option would be to run a program that automatically copies files from another folder on your computer to your SkyDrive folder. For example, let’s say you want to sync copies of important log files that a program creates in a specific folder. You could use a program that allows you to schedule automatic folder-mirroring, configuring the program to regularly copy the contents of your log folder to your SkyDrive folder. This may be a useful alternative for some use cases, although it isn’t the same as standard syncing. You’ll end up with two copies of the files taking up space on your system, which won’t be ideal for large files. The files also won’t be instantly uploaded to your SkyDrive storage after they’re created, but only after the scheduled task runs. There are many options for this, including Microsoft’s own SyncToy, which continues to work on Windows 8. If you were using the symbolic link trick to automatically sync copies of PC game save files with SkyDrive, you could just install GameSave Manager. It can be configured to automatically create backup copies of your computer’s PC game save files on a schedule, saving them to SkyDrive where they’ll be synced and backed up online. SkyDrive support was completely rewritten for Windows 8.1, so it’s not surprising that this trick no longer works. The ability to use symbolic links in previous versions of SkyDrive was never officially supported, so it’s not surprising to see it break after a rewrite. None of the methods above are as convenient and quick as the old symbolic link method, but they’re the best we can do with the SkyDrive integration Microsoft has given us in Windows 8.1. It’s still possible to use symbolic links to easily sync other folders with competing cloud storage services like Dropbox and Google Drive, so you may want to consider switching away from SkyDrive if this feature is critical to you.

• Package Manager Console For More Than Managing Packages

  - by Steve Michelotti

  Like most developers, I prefer to not have to pick up the mouse if I don’t have to. I use the Executor launcher for almost everything so it’s extremely rare for me to ever click the “Start” button in Windows. I also use shortcuts keys when I can so I don’t have to pick up the mouse. By now most people know that the Package Manager Console that comes with NuGet is PowerShell embedded inside of Visual Studio. It is based on its PowerConsole predecessor which was the first (that I’m aware of) to embed PowerShell inside of Visual Studio and give access to the Visual Studio automation DTE object. It does this through an inherent $dte variable that is automatically available and ready for use. This variable is also available inside of the NuGet Package Manager console. Adding a new class file to a Visual Studio project is one of those mundane tasks that should be easier. First I have to pick up the mouse. Then I have to right-click where I want it file to go and select “Add –> New Item…” or “Add –> Class…”   If you know the Ctrl+Shift+A shortcut, then you can avoid the mouse for adding a new item but you have to manually assign a shortcut for adding a new class. At this point it pops up a dialog just so I can enter the name of the class I want. Since this is one of the most common tasks developers do, I figure there has to be an easier way and a way that avoids picking up the mouse and popping up dialogs. This is where your embedded PowerShell prompt in Visual Studio comes in. The first thing you should do is to assign a keyboard shortcut so that you can get a PowerShell prompt (i.e., the Package Manager console) quickly without ever picking up the mouse. I assign “Ctrl+P, Ctrl+M” because “P + M” stands for “Package Manager” so it is easy to remember:   At this point I can type this command to add a new class: PM> $dte.ItemOperations.AddNewItem("Code\Class", "Foo.cs") which will result in the class being added: At this point I’ve satisfied my original goal of not having to pick up a mouse and not having the “Add New Item” dialog pop up. However, having to remember that $dte method call is not very user-friendly at all. The best thing to do is to make this a re-usable function that always loads when Visual Studio starts up. There is a $profile variable that you can use to figure out where that location is for your machine: PM> $profile C:\Users\steve.michelotti\Documents\WindowsPowerShell\NuGet_profile.ps1 If the NuGet_profile.ps1 file does not already exist, you can just create it yourself and place it in the directory. Now you can put a function inside like this: 1: function addClass($className) 2: { 3: if ($className.EndsWith(".cs") -eq $false) { 4: $className = $className + ".cs" 5: } 6: 7: $dte.ItemOperations.AddNewItem("Code\Class", $className) 8: } Since it’s in the NuGet_profile.ps1 file, this function will automatically always be available for me after starting Visual Studio. Now I can simply do this: PM> addClass Foo At this point, we have a *very* nice developer experience. All I did to add a new class was: “Ctrl-P, Ctrl-M”, then “addClass Foo”. No mouse, no pop up dialogs, no complex commands to remember. In fact, PowerShell gives you auto-completion as well. If I type “addc” followed by [TAB], then intellisense pops up: You can see my custom function appear in intellisense above. Now I can type the next letter “c” and [TAB] to auto-complete the command. And if that’s still too many key strokes for you, then you can create your own PowerShell custom alias for your function like this: PM> Set-Alias addc addClass PM> addc Foo While all this is very useful, I did run into some issues which prompted me to make even further customization. This command will add the new class file to the current active directory. Depending on your context, this may not be what you want. For example, by convention all view model objects go in the “Models” folder in an MVC project. So if the current document is in the Controllers folder, it will add your class to that folder which is not what you want. You want it to always add it to the “Models” folder if you are adding a new model in an MVC project. For this situation, I added a new function called “addModel” which looks like this: 1: function addModel($className) 2: { 3: if ($className.EndsWith(".cs") -eq $false) { 4: $className = $className + ".cs" 5: } 6: 7: $modelsDir = $dte.ActiveSolutionProjects[0].UniqueName.Replace(".csproj", "") + "\Models" 8: $dte.Windows.Item([EnvDTE.Constants]::vsWindowKindSolutionExplorer).Activate() 9: $dte.ActiveWindow.Object.GetItem($modelsDir).Select([EnvDTE.vsUISelectionType]::vsUISelectionTypeSelect) 10: $dte.ItemOperations.AddNewItem("Code\Class", $className) 11: } First I figure out the path to the Models directory on line #7. Then I activate the Solution Explorer window on line #8. Then I make sure the Models directory is selected so that my context is correct when I add the new class and it will be added to the Models directory as desired. These are just a couple of examples for things you can do with the PowerShell prompt that you have available in the Package Manager console. As developers we spend so much time in Visual Studio, why would you not customize it so that you can work in whatever way you want to work?! The next time you’re not happy about the way Visual Studio makes you do a particular task – automate it! The sky is the limit.

• Branching and Merging Improvements in TFS2010

  - by jehan

  Introducing the concept of “first class branches” is a significant improvement as part of the 2010 release with respect to version control.  Not only does it help to distinguish between folders and branches, but it enables branch visualizations. Let us see improvements in detail. ·         In TFS2008, you don’t know which of the folders are Branches: All folders looks the same, all have the folder icon. Now, In TFS 2010 there is a new icon that shows which of the folder is a Branch.       ·      There is no visual means to manage branches in TFS2008:   You dont have any means to identify which branches are related and the relation type. Now, In TFS 2010 you have visual tools to see the Branches Hierarchy. In order to see a Branch Hierarchy just Right Click the Branch and choose: Branching and Merging –> View Hierarchy     ·         In TFS2008, there is no option to track changes path between the Branches:  If you have made a merge in a Branch you can’t track from which Branch this Merge came from. Now, you have the tools that shows the path of change between the Branches, you can also see where change was added on a timeline.  In order to track a change do the following: Step1: Right click the Branch and click View History   Step 2: Choose a changeset to track and click the “Track Changeset” button.     Step 3: Choose the branches that will be in the view and click “Visualize”. In above visual, you can see that Changesets 108,109,110 and 119 where merged from Main to Release1.0 Branch and then “Release_1.0” Branched to “Dev1.0. Step4: You can also see the Merges on a Timeline by clicking on the “Timeline Tracking” button.   Creating New Branches: In TFS 2010, the creation of branches has been streamlined a bit from the process in 2008.  In 2008, creating a new branch was like every other action in the system – changes were pended on the client, and then checked in to the server. Because of this creating new branch in TFS2008 was time-consuming process.  In TFS2010, the step where changes are pended has been bypassed and now performing the branch creation is entirely on the server.  With this approach, the round trip time for downloading a copy of each file on the branch and then uploading each file again has been eliminated.  Note: In TFS2010, the new branch will be created and committed as a single operation on the server. Pending changes will not be created, it doesn’t require a check-in as it will be carried out as a single operation and it’s not possible to cancel.     Manage Branch Permissions: The properties view for branches is also different than that of ordinary folders or file, containing some metadata for the branch, relationship information, and permissions for the branch. In TFS2008, the users who have checkout and Check-in permissions can create a branch. But, In TFS2010 you can control the permissions for Branches using Manage Branch permissions.   Reparent option in TFS2010: In TFS2008, if we have two branches which don’t have parent-child relation and we want perform merge between these two branches then we have to perform baseless merge using tf.exe command line. I have two branches Release_1.0 and Dev1.0_F2 which don’t have any relation between them, that’s why when I click on merge option in Release_1.0, in Target Branch it’s not showing Dev1.0_F2 branch to perform the merges.     Let us see what can we do for this in TFS2010, first perform a TFS baseless merge to establish a relationship between the parent branch and the child branches.  It will only merge the folder, not its contents. TFS baseless merges are performed via the command line using VS2010 command prompt and do the following:   tf merge /baseless <ParentBranch> <childBranch> Check in your pending changes. It will create the link between the branches but the relationships are still not completed.  Now, select the child branch in Source Control Explorer and from the File menu choose Source Control –> Branching and Merging –> Reparent.      In the dialog box,  choose the appropriate branch as the new parent.   Click Reparent and then go to parent branch and click merge. Now, will see that in Target Branch option Dev1.0_F2 branch is added.         Converting Folders to Branches and Branches to Folders: You can convert any Folder as Branch from Context Menu by performing right click on the folderàBranching and MergingàConvert to Branch. In similar way, you can convert the Branches to Folder using Convert to Folder option available in File Menu (FileàSource ControlàBranching and MergingàConvert to Branch). This option is not available in context menu.

• Introducing sp_ssiscatalog (v1.0.0.0)

  - by jamiet

  Regular readers of my blog may know that over the last year I have made available a suite of SQL Server Reporting Services (SSRS) reports that provide visualisations of the data in the SQL Server Integration Services (SSIS) 2012 Catalog. Those reports are available at http://ssisreportingpack.codeplex.com. As I have built these reports and used them myself on a real life project a couple of things have dawned on me: As soon as your SSIS Catalog gets a significant amount of data in it the performance of the reports degrades rapidly. This is hampered by the fact that there are limitations as to the SQL statements that I can embed within a SSRS report. SSIS professionals are data guys at heart and those types of people feel more comfortable in a query environment rather than having to go through the rigmarole of standing up a reporting server (well, I know I do anyway) Hence I have decided to take a different tack with the reporting pack. Taking my lead from Adam Machanic’s sp_whoisactive and Brent Ozar’s sp_blitz I have produced sp_ssiscatalog, a stored procedure that makes it easy to get at the crucial data in the SSIS Catalog. I will spend the rest of this blog explaining exactly what sp_ssiscatalog does and how to use it but if you would rather just download the bits yourself and start to play you can download v1.0.0.0 from DB v1.0.0.0. Usage Scenarios Most Recent Execution I find that the most frequent information that one needs to get from the SSIS Catalog is information pertaining to the most recent execution. Hence if you execute sp_ssiscatalog with no parameters, that is exactly what you will get. EXEC [dbo].[sp_ssiscatalog] This will return up to 5 resultsets: EXECUTION - Summary information about the execution including status, start time & end time EVENTS - All events that occurred during the execution OnError,OnTaskFailed - All events where event_name is either OnError or OnTaskFailed OnWarning - All events where event_name is OnWarning EXECUTABLE_STATS - Duration and execution result of every executable in the execution All 5 resultsets will be displayed if there is any data satisfying that resultset. In other words, if there are no (for example) OnWarning events then the OnWarning resultset will not be displayed. The display of these 5 resultsets can be toggled respectively by these 5 optional parameters (all of which are of type BIT): @exec_execution @exec_events @exec_errors @exec_warnings @exec_executable_stats Any Execution As just explained the default behaviour is to supply data for the most recent execution. If you wish to specify which execution the data should return data for simply supply the execution_id as a parameter: EXEC [dbo].[sp_ssiscatalog] 6 All Executions sp_ssiscatalog can also return information about all executions: EXEC [dbo].[sp_ssiscatalog] @operation_type='execs' The most recent execution will appear at the top. sp_ssiscatalog provides a number of parameters that enable you to filter the resultset: @execs_folder_name @execs_project_name @execs_package_name @execs_executed_as_name @execs_status_desc Some typical usages might be: //Return all failed executions EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_status_desc='failed' //Return all executions for a specified folder EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_folder_name='My folder' //Return all executions of a specified package in a specified project EXEC [dbo].[sp_ssiscatalog] @operation_type='execs',@execs_project_name='My project', @execs_package_name='Pkg.dtsx' Installing sp_ssicatalog Under the covers sp_ssiscatalog actually calls many other stored procedures and functions hence creating it on your server is not simply a case of running a CREATE PROCEDURE script. I maintain the code in an SQL Server Data Tools (SSDT) database project which means that you have two ways of obtaining it. Download the source code You can download the latest (at the time of writing) source code from http://ssisreportingpack.codeplex.com/SourceControl/changeset/view/70192. Hit the download button to download all the source code in a zip file. The contents of that zip file will include an SSDT database project which you can open up in SSDT and publish just like any other SSDT database project. You can publish to a new database or any existing database, even [SSISDB] if you prefer. Download a dacpac Maintaining the code in an SSDT database project means that it can all get packaged up into a dacpac that you can then publish to your SQL Server. That dacpac is available from DB v1.0.0.0: Ordinarily a dacpac can be deployed to a SQL Server from SSMS using the Deploy Dacpac wizard however in this case there is a limitation. Due to sp_ssiscatalog referring to objects in the SSIS Catalog (which it has to do of course) the dacpac contains a SqlCmd variable to store the name of the database that underpins the SSIS Catalog; unfortunately the Deploy Dacpac wizard in SSMS has a rather gaping limitation in that it cannot deploy dacpacs containing SqlCmd variables. Hence, we can use the command-line tool, sqlpackage.exe, instead. Don’t worry if reverting to the command-line sounds a little daunting, I assure you it is not. Simply open a Visual Studio command-prompt and cd to the folder containing the downloaded dacpac: Type: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /action:Publish /TargetDatabaseName:SsisReportingPack /SourceFile:SSISReportingPack.dacpac /Variables:SSISDB=SSISDB /TargetServerName:(local) or the shortened form: "%PROGRAMFILES(x86)%\Microsoft SQL Server\110\DAC\bin\sqlpackage.exe" /a:Publish /tdn:SsisReportingPack /sf:SSISReportingPack.dacpac /v:SSISDB=SSISDB /tsn:(local) remembering to set your server name appropriately (here mine is set to “(local)” ). If everything works successfully you will see this: And you’re done! You’ll have a new database called [SsisReportingPack] which contains sp_ssiscatalog:   Good luck with sp_ssiscatalog. I have been using it extensively on my own projects recently and it has proved to be very useful indeed. Rest-assured however, I will be adding many new capabilities in the future. Feedback is welcome. @Jamiet

• RDA Health Checks for SOA

  - by ShawnBailey

  What is a health check in RDA? A health check evaluates something in your environment to determine whether a change needs to be considered in order to avoid a problem or optimize fuctionality. Examples of what this 'something' might be are: Configuration Parameters JVM Options Runtime Statistics What have we done for SOA? In the latest release of RDA, 4.30, we have added a Rule Set for SOA called 'Oracle SOA 11g (11.1.1) Post Installation (Generic)'. This Rule Set contains 14 SOA related health checks. These checks were all derived from common issues / solutions we see in support of the SOA product. Many of the recommendations come from the product documentation while others are covered in the SOA Knowledge Base. Our goal is that you will be able to easily identify the areas of concern and understand the guidance available from the output of the Rule Set. Running the health checks for SOA The rules that the checks use are installed with RDA and bundled by product or functional area into what are called 'Rule Sets'. To view the available Rule Sets simply run the command from the RDA home location: rda.cmd (or .sh) -dT hcve This will bring up a list of the available HCVE (Health Check / Verification Engine) Rule Sets. Each Rule Set contains a group of related rules that are used for evalutation and display of results. A rule can be considered synonymous with a single health check and they are assigned an ID, Name and Description that can be seen when they are executed. The Rule Set for SOA is option number 11 and you just enter this selection at the prompt. The Rule Set will then execute to completion. After running an HCVE Rule Set the tool will write the output to the RDA_HOME/output folder. The simplest way to view the output is to drag the .htm file to a browser but of course it can also be uploaded to a Service Request for evaluation by Oracle Support. Many of the Rule Sets will prompt you for information before they can execute their rules but the SOA Rule Set will identify the SOA domains configured in your RDA setup.cfg file. This means that you don't need to answer all of the questions again about where stuff is but it also means that you must have configured RDA for SOA. To run the Rule Set: Download the latest version of RDA from MOS Doc ID 314422.1 Configure RDA for your SOA domains. Detailed steps can be found here In it's simplest form the command is 'rda.cmd (.sh) -S SOA' Go to the RDA home location and enter the command 'rda.cmd (or .sh) -dT hcve' Select option '11' It should be noted that this our first release of a SOA Rule Set so there will probably be some things we need to clean up or fix. None of these rules will actually modify anything on your system as they are read only and do the evaluations internally. Please let us know if you have any issues with the rules or ideas for new ones so we can make them as useful as possible. The Checks Here is a list of the SOA health checks by ID, Name and Description. ID Name Description A00100 SOA Domain Homes Lists the SOA domains that were indentified from the RDA setup.cfg file A00200 Coherence Protocol Conflict Checks to see if you have both Unicast and Multicast configured in the same domain. Checks both the setDomainEnv and config.xml entries (if it exists). We recommend Unicast with fully qualified host names or IP addresses. A00210 Coherence Fully Qualified Host Checks that the host names are fully qualified or that IP addresses are used. Will fail if unqualified host names are detected. A00220 Unicast Local Host Checks that the Coherence localhost is specified for use with Unicast A00300 JTA Timeout Checks that the JTA timeout is configured for the domain and lists the value. The bundled rule will only list the current values of the JTA timeout for each SOA Domain. In the future the rule with fail with a warning if the value is 300 seconds or lower. It is recommended that timeouts follow the pattern 'syncMaxWaitTime' < EJB Timeouts < JTA Timeout. The 300 second value is important because the EJB Timeouts default to 300 seconds. Additional information can be found in MOS Doc ID 880313.1. A00310 XA Max Time Checks that the JTA Maximum XA call time is set for the domain. Fails if it is not explicitly set or if the value is less than or equal to the default of 12000 ms. A00320 XA Timeout Checks that the XA timeout is enabled and that the value is '0' for the SOA Data Source (SOADataSource-jdbc.xml) A00330 JDBC Statement Timeout Checks that the Statement Timeout is set for all SOA Data Sources. Fails if the value is not set or if it is set to the default of -1. A00400 XA Driver Checks that the SOA Data Source is configured to use an XA driver. Fails if it is not. A00410 JDBC Capacity Settings Checks that the minimum and maximum capacity are equal for all SOA Data Sources. Fails if they are not and lists specifically which data sources failed. A00500 SOA Roles Checks that the default SOA roles 'SOAAdmin' and 'SOAOperator' are configured for the soa-infra application in the file sytem-jazn-data.xml. Fails if they are not. A00700 SOA-INFRA Deployment Checks that the soa-infra application is deployed to either a cluster, all members of a cluster or a stand alone server. A00710 SOA Deployments Checks that the SOA related applications are deployed to the same domain members as soa-infra. A00720 SOA Library Deployments Checks that the SOA related libraries are deployed to the same domain members as soa-infra. A00730 Data Source Deployments Checks that the SOA Data Sources are all targeted to the same domain members as soa-infra

• Scripting custom drawing in Delphi application with IF/THEN/ELSE statements?

  - by Jerry Dodge

  I'm building a Delphi application which displays a blueprint of a building, including doors, windows, wiring, lighting, outlets, switches, etc. I have implemented a very lightweight script of my own to call drawing commands to the canvas, which is loaded from a database. For example, one command is ELP 1110,1110,1290,1290,3,8388608 which draws an ellipse, parameters are 1110x1110 to 1290x1290 with pen width of 3 and the color 8388608 converted from an integer to a TColor. What I'm now doing is implementing objects with common drawing routines, and I'd like to use my scripting engine, but this calls for IF/THEN/ELSE statements and such. For example, when I'm drawing a light, if the light is turned on, I'd like to draw it yellow, but if it's off, I'd like to draw it gray. My current scripting engine has no recognition of such statements. It just accepts simple drawing commands which correspond with TCanvas methods. Here's the procedure I've developed (incomplete) for executing a drawing command on a canvas: function DrawCommand(const Cmd: String; var Canvas: TCanvas): Boolean; type TSingleArray = array of Single; var Br: TBrush; Pn: TPen; X: Integer; P: Integer; L: String; Inst: String; T: String; Nums: TSingleArray; begin Result:= False; Br:= Canvas.Brush; Pn:= Canvas.Pen; if Assigned(Canvas) then begin if Length(Cmd) > 5 then begin L:= UpperCase(Cmd); if Pos(' ', L)> 0 then begin Inst:= Copy(L, 1, Pos(' ', L) - 1); Delete(L, 1, Pos(' ', L)); L:= L + ','; SetLength(Nums, 0); X:= 0; while Pos(',', L) > 0 do begin P:= Pos(',', L); T:= Copy(L, 1, P - 1); Delete(L, 1, P); SetLength(Nums, X + 1); Nums[X]:= StrToFloatDef(T, 0); Inc(X); end; Br.Style:= bsClear; Pn.Style:= psSolid; Pn.Color:= clBlack; if Inst = 'LIN' then begin Pn.Width:= Trunc(Nums[4]); if Length(Nums) > 5 then begin Br.Style:= bsSolid; Br.Color:= Trunc(Nums[5]); end; Canvas.MoveTo(Trunc(Nums[0]), Trunc(Nums[1])); Canvas.LineTo(Trunc(Nums[2]), Trunc(Nums[3])); Result:= True; end else if Inst = 'ELP' then begin Pn.Width:= Trunc(Nums[4]); if Length(Nums) > 5 then begin Br.Style:= bsSolid; Br.Color:= Trunc(Nums[5]); end; Canvas.Ellipse(Trunc(Nums[0]),Trunc(Nums[1]),Trunc(Nums[2]),Trunc(Nums[3])); Result:= True; end else if Inst = 'ARC' then begin Pn.Width:= Trunc(Nums[8]); Canvas.Arc(Trunc(Nums[0]),Trunc(Nums[1]),Trunc(Nums[2]),Trunc(Nums[3]), Trunc(Nums[4]),Trunc(Nums[5]),Trunc(Nums[6]),Trunc(Nums[7])); Result:= True; end else if Inst = 'TXT' then begin Canvas.Font.Size:= Trunc(Nums[2]); Br.Style:= bsClear; Pn.Style:= psSolid; T:= Cmd; Delete(T, 1, Pos(' ', T)); Delete(T, 1, Pos(',', T)); Delete(T, 1, Pos(',', T)); Delete(T, 1, Pos(',', T)); Canvas.TextOut(Trunc(Nums[0]), Trunc(Nums[1]), T); Result:= True; end; end else begin //No space found, not a valid command end; end; end; end; What I'd like to know is what's a good lightweight third-party scripting engine I could use to accomplish this? I would hate to implement parsing of IF, THEN, ELSE, END, IFELSE, IFEND, and all those necessary commands. I need simply the ability to tell the scripting engine if certain properties meet certain conditions, it needs to draw the object a certain way. The light example above is only one scenario, but the same solution needs to also be applicable to other scenarios, such as a door being open or closed, locked or unlocked, and draw it a different way accordingly. This needs to be implemented in the object script drawing level. I can't hard-code any of these scripting/drawing rules, the drawing needs to be controlled based on the current state of the object, and I may also wish to draw a light a certain shade or darkness depending on how dimmed the light is.

• Yippy &ndash; the F# MVVM Pattern

  - by MarkPearl

  I did a recent post on implementing WPF with F#. Today I would like to expand on this posting to give a simple implementation of the MVVM pattern in F#. A good read about this topic can also be found on Dean Chalk’s blog although my example of the pattern is possibly simpler. With the MVVM pattern one typically has 3 segments, the view, viewmodel and model. With the beauty of WPF binding one is able to link the state based viewmodel to the view. In my implementation I have kept the same principles. I have a view (MainView.xaml), and and a ViewModel (MainViewModel.fs).     What I would really like to illustrate in this posting is the binding between the View and the ViewModel so I am going to jump to that… In Program.fs I have the following code… module Program open System open System.Windows open System.Windows.Controls open System.Windows.Markup open myViewModels // Create the View and bind it to the View Model let myView = Application.LoadComponent(new System.Uri("/FSharpWPF;component/MainView.xaml", System.UriKind.Relative)) :?> Window myView.DataContext <- new MainViewModel() :> obj // Application Entry point [<STAThread>] [<EntryPoint>] let main(_) = (new Application()).Run(myView) You can see that I have simply created the view (myView) and then created an instance of my viewmodel (MainViewModel) and then bound it to the data context with the code… myView.DataContext <- new MainViewModel() :> obj If I have a look at my viewmodel (MainViewModel) it looks like this… module myViewModels open System open System.Windows open System.Windows.Input open System.ComponentModel open ViewModelBase type MainViewModel() = // private variables let mutable _title = "Bound Data to Textbox" // public properties member x.Title with get() = _title and set(v) = _title <- v // public commands member x.MyCommand = new FuncCommand ( (fun d -> true), (fun e -> x.ShowMessage) ) // public methods member public x.ShowMessage = let msg = MessageBox.Show(x.Title) () I have exposed a few things, namely a property called Title that is mutable, a command and a method called ShowMessage that simply pops up a message box when called. If I then look at my view which I have created in xaml (MainView.xaml) it looks as follows… <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="F# WPF MVVM" Height="350" Width="525"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="*"/> </Grid.RowDefinitions> <TextBox Text="{Binding Path=Title, Mode=TwoWay}" Grid.Row="0"/> <Button Command="{Binding MyCommand}" Grid.Row="1"> <TextBlock Text="Click Me"/> </Button> </Grid> </Window>   It is also very simple. It has a button that’s command is bound to the MyCommand and a textbox that has its text bound to the Title property. One other module that I have created is my ViewModelBase. Right now it is used to store my commanding function but I would look to expand on it at a later stage to implement other commonly used functions… module ViewModelBase open System open System.Windows open System.Windows.Input open System.ComponentModel type FuncCommand (canExec:(obj -> bool),doExec:(obj -> unit)) = let cecEvent = new DelegateEvent<EventHandler>() interface ICommand with [<CLIEvent>] member x.CanExecuteChanged = cecEvent.Publish member x.CanExecute arg = canExec(arg) member x.Execute arg = doExec(arg) Put this all together and you have a basic project that implements the MVVM pattern in F#. For me this is quite exciting as it turned out to be a lot simpler to do than I originally thought possible. Also because I have my view in XAML I can use the XAML designer to design forms in F# which I believe is a much cleaner way to go rather than implementing it all in code. Finally if I look at my viewmodel code, it is actually quite clean and compact…

• EM CLI, diving in and beyond!

  - by Maureen Byrne

  v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Doing more in less time… Isn’t that what we all strive to do? With this in mind, I put together two screen watches on Oracle Enterprise Manager 12c command line interface, or EM CLI as it is also known. There is a wealth of information on any topic that you choose to read about, from manual pages to coding documents…might I even say blog posts? In our busy lives it is so nice to just sit back with a short video, watch and learn enough to dive in. Doing more in less time, is the essence of EM CLI. It enables you to script fundamental and complex administrative tasks in an elegant way, thanks to the Jython scripting language. Repetitive tasks can be scripted and reused again and again. Sure, a Graphical User Interface provides a more intuitive step by step approach to tasks, and it provides a way of quickly becoming familiar with a product and its many features, and it is definitely the way to go when viewing performance data and historical trending…but for repetitive and complex tasks, scripting is the way to go! Lets us take the everyday task of creating an administrator. Using EM CLI in interactive mode the command could look like this.. emcli>create_user(name='jan.doe', type='EXTERNAL_USER') This command creates an administrator called jan.doe which is an externally authenticated user, possibly LDAP or SSO, defined by the EXTERNAL_USER tag. The create_user procedure takes many arguments; see the documentation for more information. Now, where EM CLI really shines and shows power is in creating multiple users. Regardless of the number, tens or thousands, the effort is the same. With the use of a standard programming construct, a loop, you can place your create_user() procedure within it. Using a loop allows you to iterate through a previously created list, creating new users until the list is complete. Using EM CLI in Script mode, your Jython loop would look something like this… for user in list_of_users:       create_user(name=user, expire=’true’, password=’welcome123’) This Jython code snippet iterates through a previously defined list of names, list_of_users, and iterates through the list, taking each name, user in this case, and creates an administrator sets the password to welcome123, but forces the user to reset it when they first login. This is only one of over four hundred procedures created to expose Oracle Enterprise Manager 12c functionality in a powerful and programmatic way. It is a few months since we released EM CLI with scripting option. We are seeing many users adapt to this fun and powerful way of using Oracle Enterprise Manager 12c. What are the first steps? Watch these screen watches, and dive in. The first screen watch steps you through where and how to download and install and how to run your first few commands. The Second screen watch steps you through a few scripts. Next time, I am going to show you the basic building blocks to writing a Jython script to perform Oracle Enterprise Manager 12c administrative tasks. Join this growing group of EM CLI users…. Dive in!

• Atheros AR2413 wireless not working after shutdown

  - by Chandrasekhar

  I am using a Ubuntu 11.04 on an Acer aspire 3680 laptop and my wifi is not working. I followed the below commands to install the madwifi driver: sudo su apt-get install subversion cd /usr/src svn checkout http://madwifi-project.org/svn/madwifi/trunk madwifi tar cfvz madwifi.tgz cd madwifi make && make install echo "blacklist ath5k" /etc/modprobe.d/blacklist.conf echo "ath_pci" /etc/modules modprobe ath_pci sudo reboot After installation I am facing the same problem. My wifi wont work after I shutdown. Infact it didn't work after suspend but I rectified that problem by the following commands: Command 1: sudo rmmod -f ath_pci sudo rfkill unblock all sudo modprobe ath_pci along with the command SUSPEND_MODULES=ath_pci added to the /etc/pm/config.d/madwifi directory. So if I suspend and then on my laptop the wifi loads well and doesn't create a problem. But if I shutdown my laptop the wifi never loads again and eachtime I have to run a Ubuntu 9.04 live CD to load it. I did try adding the Command 1 to the /etc/rc.local directory but still it doesn't work. So my question is: What should I do in order to make my wireless work without having to run a live CD of ubuntu 9.04 everytime after shutdown? Thanks.

• SQL Server - Rebuilding Indexes

  - by Renso

  Goal: Rebuild indexes in SQL server. This can be done one at a time or with the example script below to rebuild all index for a specified table or for all tables in a given database. Why? The data in indexes gets fragmented over time. That means that as the index grows, the newly added rows to the index are physically stored in other sections of the allocated database storage space. Kind of like when you load your Christmas shopping into the trunk of your car and it is full you continue to load some on the back seat, in the same way some storage buffer is created for your index but once that runs out the data is then stored in other storage space and your data in your index is no longer stored in contiguous physical pages. To access the index the database manager has to "string together" disparate fragments to create the full-index and create one contiguous set of pages for that index. Defragmentation fixes that. What does the fragmentation affect?Depending of course on how large the table is and how fragmented the data is, can cause SQL Server to perform unnecessary data reads, slowing down SQL Server’s performance.Which index to rebuild?As a rule consider that when reorganize a table's clustered index, all other non-clustered indexes on that same table will automatically be rebuilt. A table can only have one clustered index.How to rebuild all the index for one table:The DBCC DBREINDEX command will not automatically rebuild all of the indexes on a given table in a databaseHow to rebuild all indexes for all tables in a given database:USE [myDB]    -- enter your database name hereDECLARE @tableName varchar(255)DECLARE TableCursor CURSOR FORSELECT table_name FROM information_schema.tablesWHERE table_type = 'base table'OPEN TableCursorFETCH NEXT FROM TableCursor INTO @tableNameWHILE @@FETCH_STATUS = 0BEGINDBCC DBREINDEX(@tableName,' ',90)     --a fill factor of 90%FETCH NEXT FROM TableCursor INTO @tableNameENDCLOSE TableCursorDEALLOCATE TableCursorWhat does this script do?Reindexes all indexes in all tables of the given database. Each index is filled with a fill factor of 90%. While the command DBCC DBREINDEX runs and rebuilds the indexes, that the table becomes unavailable for use by your users temporarily until the rebuild has completed, so don't do this during production  hours as it will create a shared lock on the tables, although it will allow for read-only uncommitted data reads; i.e.e SELECT.What is the fill factor?Is the percentage of space on each index page for storing data when the index is created or rebuilt. It replaces the fill factor when the index was created, becoming the new default for the index and for any other nonclustered indexes rebuilt because a clustered index is rebuilt. When fillfactor is 0, DBCC DBREINDEX uses the fill factor value last specified for the index. This value is stored in the sys.indexes catalog view. If fillfactor is specified, table_name and index_name must be specified. If fillfactor is not specified, the default fill factor, 100, is used.How do I determine the level of fragmentation?Run the DBCC SHOWCONTIG command. However this requires you to specify the ID of both the table and index being. To make it a lot easier by only requiring you to specify the table name and/or index you can run this script:DECLARE@ID int,@IndexID int,@IndexName varchar(128)--Specify the table and index namesSELECT @IndexName = ‘index_name’    --name of the indexSET @ID = OBJECT_ID(‘table_name’)  -- name of the tableSELECT @IndexID = IndIDFROM sysindexesWHERE id = @ID AND name = @IndexName--Show the level of fragmentationDBCC SHOWCONTIG (@id, @IndexID)Here is an example:DBCC SHOWCONTIG scanning 'Tickets' table...Table: 'Tickets' (1829581556); index ID: 1, database ID: 13TABLE level scan performed.- Pages Scanned................................: 915- Extents Scanned..............................: 119- Extent Switches..............................: 281- Avg. Pages per Extent........................: 7.7- Scan Density [Best Count:Actual Count].......: 40.78% [115:282]- Logical Scan Fragmentation ..................: 16.28%- Extent Scan Fragmentation ...................: 99.16%- Avg. Bytes Free per Page.....................: 2457.0- Avg. Page Density (full).....................: 69.64%DBCC execution completed. If DBCC printed error messages, contact your system administrator.What's important here?The Scan Density; Ideally it should be 100%. As time goes by it drops as fragmentation occurs. When the level drops below 75%, you should consider re-indexing.Here are the results of the same table and clustered index after running the script:DBCC SHOWCONTIG scanning 'Tickets' table...Table: 'Tickets' (1829581556); index ID: 1, database ID: 13TABLE level scan performed.- Pages Scanned................................: 692- Extents Scanned..............................: 87- Extent Switches..............................: 86- Avg. Pages per Extent........................: 8.0- Scan Density [Best Count:Actual Count].......: 100.00% [87:87]- Logical Scan Fragmentation ..................: 0.00%- Extent Scan Fragmentation ...................: 22.99%- Avg. Bytes Free per Page.....................: 639.8- Avg. Page Density (full).....................: 92.10%DBCC execution completed. If DBCC printed error messages, contact your system administrator.What's different?The Scan Density has increased from 40.78% to 100%; no fragmentation on the clustered index. Note that since we rebuilt the clustered index, all other index were also rebuilt.

• Multi Monitor Setup Problems

  - by Shamballa

  I have Ubuntu 10.04 LTS - the Lucid Lynx. I have until recently been using a nVida Graphics card (NVIDIA GeForce 9800 GT) with two monitors attached, this all worked fine and dandy. A couple of days ago I bought two new identical LCD monitors for a multi monitor setup and two ATI graphics cards (ATI Sapphire Radeon HD5450). NOTE *All monitors work fine in Windows XP, 2k, Vista and 7 After I had booted into Ubuntu only one display came on, that I kind of expected anyway, then I removed the driver for the nVidia card and downloaded the ATI version which gave me the ATI Catalyst Control Center - in that only two of the displays were showing the third was disabled and showing unknown driver. I enabled the third monitor that stated "Unkown Driver" and had to reboot, upon reboot none of the displays work. I restarted and booted up into recovery mode and from now that is only what I can get into using a failsafe driver. It seems according to the log that a server is already active for Display 0 and I have to remove /tmp/.X0-lock and start again. This is what the log file is saying: Fatal Server Error Server is already active for display 0 if this server is no longer running, remove /tmp/.X0-lock and start again. (WW) xf86 closeconsole: KDSETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETMODE failed: Bad file descriptor (WW) xf86 closeconsole: VT_GETSTATE failed: Bad file descriptor ddxSigGiveUp: closing log I have tried looking at my xorg.config file but unfortunately I have not really got a clue as to how it "should" be - I have tried regenerating it using this command from a terminal: sudo dpkg-reconfigure -phigh xserver-xorg but that had no effect so I am currently stuck in failsafe driver mode but two monitors are active but are mirroring each other. I hope that this is not to long - looking back I have been going on a bit! but I am just trying to explain as much as I can... I have asked this on Linuxquestions but nobody seems to know either or at least I have not had any responses. Could some kind soul please help explain what I can do from here? I would be eternally grateful. Chris * Update * Removing xorg.conf does nothing other than allowing me to use only two monitors - using the command: sudo aticonfig --initial generates the xorg.conf file below: but does not work either - I just get two monitors...

This is so much harder than I thought it would be, I don't think Ubuntu likes ATI for multi (3) monitors or maybe the other way around. Can anyone help still?

The problem only occurs on the first two that are running 2008 non R2. Running depends.exe on all three servers gives equal results for the nonR2 servers: My DLL is shown as x86 (compiled as AnyCPU, running in x64 w3wp), all other modules show as x64. Missing IESHIMS.DLL and LINKINFO.DLL - both of these seem to be red herrings according to Google. The third server shows the same, except it does not miss LINKINFO.DLL All servers are running IIS7 (7.5 for the R2 one) under a custom domain account that has been granted the necessary permissions: aspnet_regiis -ga [user] Load user profile is set to false on all three servers. I've tried setting this to true on one of the faulting servers, according to: http://stackoverflow.com/questions/1846816/iis7-failed-to-grant-minimum-permission-requests By running processmonitor I can see that it's now using the C:\Users\TEMP\AppData\Local\Temp directory for various temp files - the other ones are not using any such directory. So far I'll let it run in this way to see if this changes anything. I'm in doubt however given that the third server is not exhibiting the problems, yet still has "Load user profile" set to the same value, false. I've also tried running Fuslogvw on all three servers, logging binding failures to disk. All three servers report the same binding errors for VJSharpCodeProvider and CppCodeProvider, but these seem to be normal as well and can be solved by not defining the DEBUG and TRACE constants during build. We're running about 500 websites on each server (identical, load balanced), of which 50 are under moderate load, the problem has arisen both under heavy load as well as under minimal load however. Right now I'm waiting for the errors to happen again so I can hopefully see a pattern and determine whether "Load user profile" alleviates the issue. Any suggestions in the meantime would be very welcome! Also, I don't understand how the lack of "Load user profile" would cause an issue like this? And even further, how it would seemingly work on R2 but not on plain 2008? Thanks!

• Problem deploying portlets on JBoss Portal 2.7.2: Not a canonical value

  - by Dee

  I just downloaded the JBoss Portal Server 2.7.2 (JBoss Portal + JBoss AS 4.2.3 bundle to be precise) and tried deploying portlets just as the SimpleHelloWorld provided in the samples. The portlet gets deployed fine but when I put it on a page I get the following exception. I tried adding other Portlets as well (such as the booking MVC portelt supplied with Spring WebFlow dist) but the same problem happens. The problem happens when the new instances are created by me, example when i create a new instance of CMS Portlet, I get the same error. If I use an existing instance it works. If I deploy a portlet that creates an instance using the "portle-instances.xml" then it works fine, but creating additional instances using the Admin and deploying them on page fails due to the following error. What am I doing wrong? Can anyone please help? javax.servlet.ServletException: java.lang.IllegalArgumentException: Not a canonical value SimplestHelloWorldWindow

• javax.validation.ConstraintViolationException: validation failed for classes during update time for groups

  - by Tim

  Hello all! I have a Java / Spring MVC 3 application, using Hibernate and a MySQL database. In my controller, I have this source code: Set<ConstraintViolation<Person>> failures = validator.validate(p); if (failures.isEmpty()) { Project project = this.projectService.findProjectById(projectid); Person newPerson = this.personService.addPerson(p); Set<Person> persons = this.personService.getAllPersonsByProjectId(projectid); persons.add(newPerson); project.setPersons(persons); Set<ConstraintViolation<Project>> failures1 = validator.validate(project); if (!failures1.isEmpty()) { System.out.println("ERROR"); } else { System.out.println("NO ERROR"); } this.projectService.updateProject(project); return Collections.singletonMap("person", newPerson); } Project and Person are a many-to-many relation annotated with @manytomany and Project is the mapping owner. The new Person is added, but on the line with this.projectService.updateProject(project); I get an error. What it does it this in a Dao Hibernate implementation: public void updateProject(Project p) { SessionFactory sessionFactory = HibernateUtil.getSessionFactory(); Session sess = sessionFactory.getCurrentSession(); Transaction tx = sess.beginTransaction(); sess.update(p); tx.commit(); } It failed on the line tx.commit();. My check with if (!failures1.isEmpty()) { tell me that there are nor errors in my project. So what's wrong here? And why there is a validation of my project? I did not call a validation method... so why is there a org.hibernate.cfg.beanvalidation.BeanValidationEventListener.validate()? I hope, someone can help me how to fix this! Best Regards, Tim.

• How to go about converting this classic asp to asp.net

  - by Phil

  I have some classic asp code that needs converting to asp.net. So far I have tried to achieve this using datareaders and repeaters and had no luck as the menu loops through 4 different record sets, passing along the menuNid before moving to the next record. Please can you tell me what method you would use to conver this code... i.e datareaders? dataset? etc? Thanks <% set RSMenuLevel0 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from T where (DepartmentID = 0 and GroupingID = 0 and Publish <> 0) order by OrderID") %> <% if session("JavaScriptEnabled") = "False" Then %> <% while not RSMenuLevel0.EOF if RSMenuLevel0("Publish") <> 0 then Menu0heading = RSMenuLevel0("Heading") Menu0id = RSMenuLevel0("id") %> <%if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then%> &nbsp;<a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>"><%=Menu0heading%></a> <%else%> &nbsp;<a href="/default.asp?id=<%=Menu0id%>"><%=Menu0heading%></a> <%end if%> <% end if RSMenuLevel0.MoveNext wend %> <% else %> <ul id="Menu1" class="MM"> <%if home <> 1 then%> <!-- <li><a href="/default.asp"><span class="item">Home</span></a> --> <%end if%> <% numone=0 while not RSMenuLevel0.EOF ' numone = numone + 1 Menu0heading = RSMenuLevel0("Heading") 'itemID = lcase(replace(Menu0heading," ","")) Menu0id = RSMenuLevel0("id") if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then url = RSMenuLevel0("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%else%> <li><a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel0("id")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <% set RSMenuLevel1 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from T where (DepartmentID = 0 and GroupingID = " & Menu0id & " and Publish <> 0) order by OrderID") if not RSMenuLevel1.EOF then %> <ul> <% while not RSMenuLevel1.EOF Menu1heading = RSMenuLevel1("Heading") Menu1id = RSMenuLevel1("id") if RSMenuLevel1("url") > "" and RSMenuLevel1("moduleid") = 0 then url = RSMenuLevel1("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%else%> <li><a href="http://<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel1("id")%>"><%=Menu1heading%></a> <%end if%> <% set RSMenuLevel2 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from T where (DepartmentID = 0 and GroupingID = " & Menu1id & " and Publish <> 0) order by OrderID") if not RSMenuLevel2.EOF then %> <ul> <% while not RSMenuLevel2.EOF Menu2heading = RSMenuLevel2("Heading") Menu2id = RSMenuLevel2("id") if RSMenuLevel2("url") > "" and RSMenuLevel2("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel2("url")%>" target="<%=RSMenuLevel2("urltarget")%>"><%=Menu2heading%></a> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel2("id")%>"><%=Menu2heading%></a> <%end if%> <% set RSMenuLevel3 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from T where (DepartmentID = 0 and GroupingID = " & Menu2id & " and Publish <> 0) order by OrderID") if not RSMenuLevel3.EOF then %> <ul> <% while not RSMenuLevel3.EOF Menu3heading = RSMenuLevel3("Heading") Menu3id = RSMenuLevel3("id") if RSMenuLevel3("url") > "" and RSMenuLevel3("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel3("url")%>" target="<%=RSMenuLevel3("urltarget")%>"><%=Menu3heading%></a></li> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel3("id")%>"><%=Menu3heading%></a></li> <%end if%> <% RSMenuLevel3.MoveNext wend %> </ul> <% end if RSMenuLevel2.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel1.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel0.MoveNext %> </li> <% wend %> </ul> <% end if %>

• Is it possible to convert this asp to asp.net?

  - by Phil

  I have been tasked with sifting through the worst classic asp spaghetti i've ever come across. The script runs a series of recordsets in sequence, getting 1 record at a time. As the record is built it takes the id and passes it to the next loop, which gets data, and passes on the id to the next loop. It then continues in this manner and builds an unordered list, kicking out the required html as it goes. Here are my efforts so far: have a class delivering data via sqldatareaders and output these to nested repeaters (this failed due to not being able to loop and get the id) Have a datatable populated with all the required data, then datatable.select to filter it out. have 4 datareaders looping and building the ul arraylists (I couldnt get the id's to match up) Please can you suggest the best method (with a bit of sample code if possible) to go about doing this conversion? Here is the code (sorry its long / horrible / spaghetti!!!) <% set RSMenuLevel0 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = 0 and Publish <> 0) order by OrderID") %> <% if session("JavaScriptEnabled") = "False" Then %> <% while not RSMenuLevel0.EOF if RSMenuLevel0("Publish") <> 0 then Menu0heading = RSMenuLevel0("Heading") Menu0id = RSMenuLevel0("id") %> <%if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then%> &nbsp;<a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>"><%=Menu0heading%></a> <%else%> &nbsp;<a href="/default.asp?id=<%=Menu0id%>"><%=Menu0heading%></a> <%end if%> <% end if RSMenuLevel0.MoveNext wend %> <% else %> <ul id="Menu1" class="MM"> <%if home <> 1 then%> <!-- <li><a href="/default.asp"><span class="item">Home</span></a> --> <%end if%> <% numone=0 while not RSMenuLevel0.EOF ' numone = numone + 1 Menu0heading = RSMenuLevel0("Heading") 'itemID = lcase(replace(Menu0heading," ","")) Menu0id = RSMenuLevel0("id") if RSMenuLevel0("url") > "" and RSMenuLevel0("moduleid") = 0 then url = RSMenuLevel0("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%else%> <li><a href="http://<%=RSMenuLevel0("url")%>" target="<%=RSMenuLevel0("urltarget")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel0("id")%>" <%if numone=1 then%>class="CURRENT"<%end if%>><span class="item"><%=Menu0heading%></span></a> <%end if%> <% set RSMenuLevel1 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu0id & " and Publish <> 0) order by OrderID") if not RSMenuLevel1.EOF then %> <ul> <% while not RSMenuLevel1.EOF Menu1heading = RSMenuLevel1("Heading") Menu1id = RSMenuLevel1("id") if RSMenuLevel1("url") > "" and RSMenuLevel1("moduleid") = 0 then url = RSMenuLevel1("url") if instr(url,"file:///") > 0 then %> <li><a href="<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%else%> <li><a href="http://<%=RSMenuLevel1("url")%>" target="<%=RSMenuLevel1("urltarget")%>"><%=Menu1heading%></a> <%end if%> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel1("id")%>"><%=Menu1heading%></a> <%end if%> <% set RSMenuLevel2 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu1id & " and Publish <> 0) order by OrderID") if not RSMenuLevel2.EOF then %> <ul> <% while not RSMenuLevel2.EOF Menu2heading = RSMenuLevel2("Heading") Menu2id = RSMenuLevel2("id") if RSMenuLevel2("url") > "" and RSMenuLevel2("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel2("url")%>" target="<%=RSMenuLevel2("urltarget")%>"><%=Menu2heading%></a> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel2("id")%>"><%=Menu2heading%></a> <%end if%> <% set RSMenuLevel3 = conn.execute("select id, DepartmentID, GroupingID, Heading, OrderID, Publish, moduleid, url, urltarget " &_ "from Grouping where (DepartmentID = 0 and GroupingID = " & Menu2id & " and Publish <> 0) order by OrderID") if not RSMenuLevel3.EOF then %> <ul> <% while not RSMenuLevel3.EOF Menu3heading = RSMenuLevel3("Heading") Menu3id = RSMenuLevel3("id") if RSMenuLevel3("url") > "" and RSMenuLevel3("moduleid") = 0 then %> <li><a href="http://<%=RSMenuLevel3("url")%>" target="<%=RSMenuLevel3("urltarget")%>"><%=Menu3heading%></a></li> <%else%> <li><a href="/default.asp?id=<%=RSMenuLevel3("id")%>"><%=Menu3heading%></a></li> <%end if%> <% RSMenuLevel3.MoveNext wend %> </ul> <% end if RSMenuLevel2.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel1.MoveNext %> </li> <% wend %> </ul> <% end if RSMenuLevel0.MoveNext %> </li> <% wend %> </ul> <% end if %>
