6. Click Test connection for successfull connection.
7. Exit and Click import Icon.
8. Select the default directory location to C:\program files\ibm\WID7_WTE\runtimes\bi_v7.
9. Click next and import it.
10. Now, you can able to install Websphere Test Environment without any issue.

Restarting Application Servers With Nodeagent – WebSphere Application Server V7,V8

In WebSphere 7 or 8, by default, the Nodeagent will take no action if an application server fails.  To have the Nodeagent intervene and automatically restart a failed application server instance, the ‘monitoring policy’ must be set for that application server.  In the admin console, perform the following:

1 . –> Java and Process Management –> Monitoring Policy
2.  Check the box next to “Automatic Restart”
3.  In the “Node Restart State“, set the state to “STOPPED”


The actions above will allow the nodeagent to auto-restart a failed or killed application server.  It is important that the ‘Node Restart State” be set to ‘STOPPED“.  If set to “RUNNING“, not only will the nodeagent restart a failed or killed application server, but it will autostart the application server upon a nodeagent restart.  This may be unwanted in certain environments where application servers are only supposed to run at certain times or if there is a specific application start order.
If you wish to have the nodeagent automatically start application servers when it comes online, set the state to “RUNNING“.

Stuck messages occur for WebSphere Process Server (WPS) and WebSphere Enterprise Service Bus (WESB) on SCA.SYSTEM.etail_cell01.Bus destinations.

Environment

The problem can occur in WebSphere Process Server or WebSphere Enterprise Service Bus-related modules that are deployed on a server or clustered environment. This problem occurs only for asynchronous messaging on SCA modules.

Diagnosing the problem

To diagnose the problem, monitor the queue destinations for the message counter and review the settings for the forward routing path of the affected queue destinations.

Monitor the queue destinations in an asynchronous communication scenario. If the number of messages on the queue only increases, then the messages are not routed forward. This scenario applies to destinations that do not have a defined forward routing path (except the module destination, which has an applied MDB, which reads the messages from the queue).

Use the Service Integration Bus Explorer to monitor module-related queues or review the number of messages on the queue using the administrative console:

Administrative console Service integration Buses SCA.SYSTEM.cellName.Bus Destinations sca/destinationName Queue points destinationName@messagingEngineName Runtime tab Current message depth

Use the refresh button to get the current value of the message counter to monitor the behavior over time:





Stuck messages on the module destination queue (optional)
If messages remain on the module destination queue, verify that the activation specification of the MDB that is listening on that queue is configured correctly:

Administrative console Resources Resource adapters J2C activation specifications sca/moduleName/ActivationSpec J2C activation specification custom properties

Check that busName refers to the correct SCA bus (SCA.SYSTEM.cellName.Bus) and that destinationName refers to the module destination (sca/moduleName).

Resolving the problem

Follow this procedure to resolve the problem:

1. Identify the destination where messages are stuck.
2. Set the correct forward routing path on the destination (set the path to the module destination).
3. Save the master configuration. 

Example :

Destination Name : sca/PubProdMED/component/PubProdMF
ModuleName :  PubProdMED
Routing Path:


The messages should immediately be routed to the specified target destination. You do not need to restart the server.

Deleting Records From Failed Event Manager In Websphere Application Server [ WESB & WPS ]

The WebSphere application server stores all exception's in failed event manager. If FEM is full, then clearing FEM Records through Admin Console is not possible.

In this situation, we have two options to remove all FEM.

Option 1:
=======

Delete FEM records from WPSDB database . Run the below query in order.

delete from FAILEDEVENTS;
delete from FAILEDEVENTBOTYPES;
delete from FAILEDEVENTDETAIL;


Option 2:
=======

Delete FEM by jython scripts.

The script must be saved in a file and can be run on a single server profile as well as a
clustered environment (run on deployment manager) using the following command:

1.  cd Deployment manager  [ or ] Profile Name/bin 
2.   Run wsadmin.(bat|sh) -lang jython -f jythonScriptName -user wpsAdminUserName -password wpsAdminPassword

Ex: wsadmin.bat -lang jython -f /opt/Websphere/AppServer/scripts/FEMScript.py -user admin -password admin


FEMScript.py
===========
# lookup the failed event manager
objstr = AdminControl.completeObjectName('WebSphere:*,type=FailedEventManager')
obj = AdminControl.makeObjectName(objstr)

# count the overall number of failed events
fecount = AdminControl.invoke(objstr,"getFailedEventCount")
print "Failed event number before discarding: ", fecount

delnum = 100
fecount = int(fecount)

while (fecount > 0):
    if fecount < 100:
        delnum = fecount
        fecount = 0
    else:
        delnum = 100
        fecount = fecount - 100
      
    # get 100 failed events
    msglist = AdminControl.invoke_jmx(obj,'getAllFailedEvents',[delnum],['int'])

    # discard 100 events in single batch run
    print "Discarding ", delnum, " failed events"
    AdminControl.invoke_jmx(obj,'discardFailedEvents', [msglist],['java.util.List'])

# count the overall number of failed events
fecount2 = AdminControl.invoke(objstr,"getFailedEventCount")
print "Failed event number after discarding: ", fecount2

WPS : Unable to Install appllication on server "Application is already Exist on Server". Module status is unknown in SCA module section.

Issue: I am trying to install one application on server. It's unable to install giving exception as " already exist on server".
In admin console go to --> SCAModules : there i am finding my module over there but the state of the module is unknown. i tryed to un-deploy from there. it's not able to un-deploy. Even i am unable to remove that application from server from admin consol too..

Solution :
1. first we have to stop the server.
2. we have to remove particular application from all the folder in server profile.
3.One more main thing is go to installation folder-->  \profiles\qbpmaps\config\cells\qcell go to this path and open "cell-core.xml" file and remove SCAModules entry of that particular application from this file.
4. Start the server
now we can able to deploy that same application successfully.


OR

You can also force the uninstall with the following command:

<>\bin\wsadmin.bat -user <> -password <> -lang jacl -f <>\ProcessChoreographer\admin\bpcTemplates.jacl -uninstall <> -force

WAS 7 – Busines level Application can not be removed

In WAS 7, IBM introduced the new concept BLA (business level application) which can include EAR, JAR or share libraries.

However, some times when you update a EAR file from console but failed, which cause the Enterprise Application was removed but BLA was still left. When you redeploy the same module, the module can not be deployed, and you will see the following error when you want to delete the existing BLA:
CWWMH0149E: Cannot delete business-level application “WebSphere:blaname=AppEAR” because it contains composition units. Delete all composition units which belong to the business-level application, and then delete the business-level application. Check log for details.
As a matter of fact, you already removed all composition units, and you can not see any composition units belong to this BLA from administrative console or even using wsadmin scripts.

Here is a way for how to remove the isolated BLA if BLA can not be removed without any composition units belonging to it.

1) stop the WebSphere Application Server.
2) backup the WebSphere profile configuration using “backupConfig.sh” command
3) go to directory /config/cells//blas
4) remove the directory of specified BLA
5) go to directory /config/cells//cus
6) remove the directory of specified BLA
7) go to directory config, remove temp directory
8) go to directory , remove wstemp and temp directory
9) restart the WebSphere Application Server
10) redeploy the module.
this is the way I solved this problem. I hope someone can provide the better way to solve this issue.

Using WebSphere variable in JavaEE application

There is a section in the WebSphere Admin console called WebSphere variables (located under Environment), where you can … manage WebSphere variables (WAS variables). But how can one use these WAS variables within a JavaEE application? There is a proprietary way to load them which I will not mention here.

A better way in my opinion is to bridge the WAS variable to an environment variable. Then it can simply be accessed through System.getProperty(“varName”); It’s also easy to access the variable on Tomcat without touching the code.

To bridge a WAS variable:

1. Log on to your WAS console.
2. Add a WAS variable “myapp.myVar” under Environment -> WebSphere variables
3. Go to (something llike) Servers -> Server Types -> Websphere application servers -> YOUR_SERVER -> Java and process management -> Process definition -> Java virtual machine -> Custmo properties
4. Define a new variable myapp.myVar = ${myapp.myVar}
5. Save and restart.

The value of myapp.myVar can now be obtained: System.getProperty(“myapp.myVar”)

Note : 

If you have cluster environment then this configuration should be in all server of cluster. 

WebSphere Message Broker version 8 is out!

Hot on the heels of the latest goodness in WebSphere MQ, it’s the turn of IBM’s Enterprise Service Bus – WebSphere Message Broker – to get a major new update.
WMB v8.0 was announced back in early October and has just arrived ready for  download in versions for distributed platforms, System z mainframes, and as a Hypervisor Edition for Linux and AIX (to be provisioned via the IBM Workload Deployer appliance).
As I did with WMQ last month, I wanted to take a moment to break out and highlight some of the key things in this release that you may have missed from the announcement letter. This won’t be a comprehensive list of everything, but I  want to point out some of the cooler features that you’ll want to be aware of. So, here we go…
(I’ve included a few screenshots to whet your appetite, click for larger versions!)
A simpler development experience
Version 8 brings a number of enhancements to the development experience, but one worth highlighting is what we call “Apps and Libs” – the idea that sets of message flows may be grouped into a unit called an Application which can be deployed, stopped and started as a whole. With Libraries, there are also truly re-usable assets like .esql files, or sub-flows, which can be deployed and updated separately, and invoked dynamically at runtime. This is a key change in the way that the Broker works – previously, sub-flows were compiled into the main flow and changing one required redeployment of all flows using it… they are now dynamically linked when needed, so they can be deployed and replaced more easily.
A new standards-based parser and message modeler
A new Data Format Description Language (DFDL, which you’ll sometimes hear called “daffodil”) enables any text or binary data to be understood within the message model. The Broker has had the “MRM” for many years, so of course could already do this, but DFDL is a new industry standard which can supersede the MRM (of course, you can continue to use your existing flows and message formats – you’re not forced to use DFDL). There’s a new mapper, too.
More importantly, coming along with DFDL and the mapper is a really, really nice set of utilities for testing message models inside the Toolkit – you’ll now be able to confirm that the model matches the test data without having to go through a full model->deploy-> test-at-runtime cycle. I saw this demo’ed at the WebSphere Technical Conference in Berlin during October and was blown away by it – it would have saved me a lot of time back in my consulting days!
Comprehensive .NET support
If you have .NET applications, assemblies, or services on the Windows platform, and you want to access those from your message flows – you can. If you want to write your message flow logic using C# or VB.NET or any .NET 4.0 CLR-supported language, using Visual Studio – you can.
If you don’t know how to get started with this stuff, the Toolkit has a new .NET Pattern to lead you by the hand and get you going quickly, and project wizards for Visual Studio.So, if you want a high-performance ESB platform that connects “anything to anything”, with minimal need to learn new skills, and run it on Windows with deep .NET integration – this release is going to cover your requirements.
Web administration
Delivered in version 8 is a first stage in making the Broker more easy to administer from a lightweight client – a web browser. Whilst power users and existing administrators can continue to use the Message Broker Explorer GUI, there is now an easy way to enable an optional web interface for basic administration tasks. Continuing the theme of simplicity the product has followed for a while, no additional moving parts (app or web servers) are required! Version 8.0 provides read-only views of running Applications and access to the log – more capabilities will be rolled into this interface in the future.

Record and Replay
Sometimes, when you are dealing with a set of end-to-end flows of data between applications, you may want the capability to record what is going on, and to replay specific scenarios and sets of events. This could be the case in audit, test, and many other scenarios. Another of the massive enhancements in version 8 is the Broker’s response to this requirement – again delivered using the same simple, lightweight interface offered by the web administration tool.
This also builds on technology around monitoring that has been progressively built into the Broker over the past couple of releases, so there are some really solid foundations and it is straightforward to set up.
Richer, yet easier to use
Just as I highlighted in my piece about WebSphere MQ 7.1, the Hursley teams have been strongly focused on “consumability” (translation for non-IBM-speakers = UX) for a number of years now. WMB continues to add capabilities that make it a richer, stronger integration platform, but also smooths out rough edges seen in earlier releases and is just… well… more productive to use. There’s even a drive to reduce the jargon and make the Broker logs more easy to understand, with new Activity Logging which aims to explain what a flow is doing in plain language (“GET message queue X”, “Update DB table Z”, and so on).
Taken together, the new wizards, web interfaces, integrated testing tools, message modelling tools, reduced dependencies, lightweight deployment with apps and libs… the combination just makes it a much more enjoyable experience for developer and administrators. And there’s a new installer, too.
The “papercuts” and node additions lists are huge: new JMSReceive node; new options for the File nodes; new Connect:Direct nodes; WS-ReliableMessaging support in the SOAP nodes; ability to install without root privileges; dynamic configuration of services without the need to restart execution groups… the list just goes on! Check out the product Information Center for more details on all of the features I just don’t have space to list.
… and finally…
Huge congratulations to some hard-working development teams in Hursley, Toronto and Bangalore in getting this release out there. As I’ve said before, I’ve been using the Broker for 10 years now and it just keeps getting better, and better. These guys are a very strong set of developers who turn out a fantastic, high quality product every time. Special thanks to MGK, @mqmatt, and @domstorey for some of the screenshots in this post
Footnote: version 8.0 is friendly to developers who use Ubuntu, too! Anton (my go-to guy on all things Debian – listen to him!) has some good advice about running WMB or WMQ on Ubuntu and Debian
