For the life of me, I can’t seem to find a simple tool that will allow me to generate a DDL from an XSD definition. I’ve checked out XML Spy, StylusStudio and even the entire suite of Rational Products (Rational Software Architect & Rational Data Architect). It seems like this option was present in older […]
Seven Reasons Why Corporate Blogs Suck
From the blog ‘Ben means Business‘, Ben Jones lists the 7 reasons why corporate blogs suck. I really like the first reason: Reason#1: Fear of Transparency People who read blogs expect to “know” the author, and participate in discussions with the author and other readers. They enjoy an atmosphere that is genuine and has a […]
IBM Installation Manager Tip: Don’t “Save Files For Rollback”
The ability to roll back a update is a nifty idea. The theory is that you installed something that broke your platform. You can now just ‘undo’ the install. In practice, it’s a feature that next to nobody uses. It requires a deep-faith in the programmers of the rollback logic to return the system to […]
WebSphere Integration Developer Upgrade from 6.1 to 6.1.2 – Two Hours
I started my update from 6.1 to 6.1.2 and the process took two hours (not including download times). That’s unacceptable. Most of the time was spent installing the WebSphere Process Server fixes. The UI appeared frozen for about an hour (still responsive, just that the progress bar didn’t move). When I jumped down to the […]
Upgrading WebSphere Integration Developer v6.1 – Installation Manager
In v6.1 you now use the installation manager to update WID to the various fixpacks. I had a very old install of v6.1 GM in a VM that I started up and couldn’t seem to update. I was getting the message “No updates found.”. Then I realized that the VM’s network card was set to […]
WebSphere Application Server: High Availability to JMS Clients?
I was asked an interesting question. If your messaging engine is in a cluster and it fails over from one node to the next, how to my clients know which node is now hosting the Messaging Engine? I haven’t run this scenario myself so I don’t know. I do know that the datapower allow you […]
WebSphere Enterprise Service Bus does not support Event Sequencing
Cheers to David Currie for pointing out that while the WebSphere Integration Developer user interface allows you to specify an event sequencing qualifier inside a mediation module, if you attempt to deploy the solution to an WebSphere Enterprise Service Bus Server, you’ll get exceptions. Interestingly enough, if you deploy the same Mediation Module to WebSphere […]
BPEL: Beware the use of nested loops in a short running process
One of the restrictions when dealing with a short running process is that it must always run within a single transaction. The implication is that the process must complete within the default transaction timeout window. On an application server, this is 120s. We had an issue where our Process Server was creating a large number […]
WebSphere Process Server v6.1 API
There are various API’s that are provided as a part of WebSphere Process Server. EJB API There is the standard EJB lookup method for the four JNDI’s (Human Task, BusinessFlow, Relationship etc). EJB provides slightly more functionality than the Web service or JMS interface. The generic EJB API supports Remote Artifact loading so you don’t […]

My Next Opportunity: Oracle Fusion
As my gig here in Toronto doing WebSphere Process Server implementations comes to a close, I’m going to be moving on to a new opportunity using Oracle Fusion and Oracle BPEL. This should be very interesting as I will be able to directly compare and contrast the two integration engines from the perspective of someone […]
WebSphere Adapter for JDBC Export and SQL Server 2000: Table Locking while Polling
A technote was published for customers who use the WebSphere Adapter for JDBC for inbound processing of an SQL Server 2000 database. Apparently, the adapter will lock the entire event table (bad!). The ‘fix’ aka workaround is to use a view to the event table and then set a custom property inside the adapter.
Passed Certification Test 284: IBM WebSphere DataPower SOA Appliances Firmware V3.6.0
I re-wrote IBM DataPower Certification test 284 over the weekend and passed with a 75% when requiring a 60%. Taking the course made my life a lot easier. I still spent two hours writing and reviewing the answers but I was a lot more confident about passing when I ended the test. I did notice […]

The Support Authority: A systematic approach to problem solving
Problem determination is not an exact science, but it’s also not rocket
science. A methodical approach will help your problem solving techniques become more
organized, systematic, and, ultimately, more effective. (IBM WebSphere Developer Technical Journal)
Taking component testing to the next level in WebSphere Integration Developer
Test case support, a new feature of WebSphere Integration Developer V6.1, lets you create a test suite, a collection of test cases. The test client allows you to test each component in
isolation or as part of the whole module, or system of modules. You can run the suites of test cases at any time to show you whether your latest changes cause tests to fail.
WAS: Resolution to Messages in the SIB locked forever
In a cluster where the messaging engine has failed over between nodes, a situation could arise where the transaction log (‘tranlog’) has become corrupt or is unrecoverable. In this situations, you may see messages on SIB Queues that are in the LOCKED state but are unprocessed. If you factor in a sequential delivering of messages, […]
WebSphere Application Server: -recovery flag
If you have a server that crashed without a clean shutdown, you may have transactions that are in progress and need to be recovered. In development, you would likely jusy delete the tranlog. On a production machine, you will likely need the following useful command line option when starting your server: startServer <server> -recovery This […]
Tip: WebSphere Process Server – Do not delete the ‘tranlog’ on a production server
In development mode, one of the steps to ‘clean up’ from a wonky process server instance is to delete the wstemp, temp directories along with the ‘tranlog’. The ‘tranlog’ is an internal file that WebSphere Application Server uses to manage in-flight transactions and attempt to recover them should the server crash. When you delete the […]

WebSphere Process Server: Messages sitting on queues unprocessed
We’re battling another runtime problem. We’re on 6.0.2.3 and WAS 6.0.2.23 and have a situation where our modules that enable Event Sequencing seem to deadlock when trying to pick messages up off the queue. The transactions then time-out in a sea of exceptions. We have a messaging engine cluster (set to 1 of N) and […]
