Configuring SIB J2SE client with SSL
Wednesday, July 16th, 2008Dynamic JMS endpoints
Tuesday, July 15th, 2008In an earlier post I promised an example of where service integration bus mediations still have a role to play in a WebSphere ESB environment. WebSphere ESB currently only supports dynamic endpoints on an import or callout (those that can be changed at runtime by a mediation flow) for SCA and web service bindings. In this post I’ll show how a service integration bus mediation can be used to add dynamic behaviour to a JMS binding.

Deployment environments during profile creation
Tuesday, July 8th, 2008Today I was trying to work out why a WebSphere ESB customer wasn’t seeing the default deployment environment created when using manageprofiles to create a Network Deployment topology. They had specified the appropriate topologyPattern and topologyRole parameters. It turned out that they were missing the ndtopology option which should be set to true. This was perhaps excusable as the help for the template doesn’t list this option and even the InfoCenter documentation manages to get the case incorrect. As on previous occasions, I spotted this omission by running through the graphical Profile Management Tool and comparing the parameters that it generates in the invokeWSProfile entry near the top of the logs/manageprofiles/<profile_name>_create.log file.
Event sequencing qualifier and WebSphere ESB
Saturday, June 14th, 2008As this has cropped up a couple of times recently and, as far as I’m aware, there is still no information in the public domain, I thought I’d stick my neck out and post about it. WebSphere Integration Developer allows you to add an event sequencing qualifier to components in a mediation module but the required runtime support for that qualifier only exists in WebSphere Process Server not in WebSphere ESB. In other words, for that qualifier to work, the mediation module must then be deployed to WebSphere Process Server.
Mediation handler tooling broken
Tuesday, June 10th, 2008Despite being sidelined by the arrival of WebSphere ESB, there are still times when it is useful to use the mediation support in WebSphere’s service integration bus (of which more in another post). It’s obviously a while since I’ve done it though as apparently the mediation handler tooling in Rational Application Developer has been broken since v7 was released. I’m told that the fix will finally make it in to 7.0.0.7.
Feature Pack for Web Services notes
Friday, May 30th, 2008A couple of notes if you have, or are thinking of, embarking on use of the Feature Pack for Web Services, based on a recent client’s experiences. Firstly, make sure you heed the rules on profile augmentation in the InfoCenter. In particular, note that augmentation of a Cell profile is not supported. For Network Deployment you must have a separate deployment manager profile.
Secondly, if you are experiencing sluggish response times, 100% CPU or even hangs when either deploying or accessing applications following augmentation, then consider applying APAR PK58537. Note that the application need not be using any new functionality in order to experience this behaviour and it’s possible that you might not see the particular IOException stated in the problem description. This fix is targeted for inclusion in 6.1.0.17.
Thursday @ WSTC
Thursday, May 8th, 2008Went along to see my UK colleague Andy Piper‘s presentation on "Using Social Software to Improve Your Effectiveness at Work". Andy’s an engaging speaker and his presentation was well thought out and put together. As a result I signed up for a twitter account but we’ll have to wait and see whether it gets much use let alone improving my effectiveness at work. It did also prompt me to revisit an internal file sharing tool which, having previously not realised that access could be restricted, I had discarded as much of the material I want to share is of a confidential nature.
Wednesday @ WSTC
Thursday, May 8th, 2008The first slot of the day was one of those rare occasions where I wasn’t quite sure what to attend. In the end I opted for Alex Polozoff’s "Large Topology Tactics and Tradeoffs" presentation as I have great respect for his opinions. The emphasis here was not so much on the technology but the processes and the people. Most of it seemed common sense (at least to me) but the presentation should be a useful resource for anyone embarking on large scale WebSphere topologies.
