There is a Redpaper which provides some excellent advice when it comes to tuning WebSphere ESB 6.0.2 for performance. However, you’ll have to wait a little bit for the Version 6.1 update. In the meantime, whilst all of the current best practice still stands, I thought I would post a couple of additional tips that are specific to the latest release.

Performance tuning WebSphere ESB 6.1
Monday, January 28th, 2008Jython scripting
Monday, January 28th, 2008I’ve had the pleasure of working with my UKISA colleague Andrew Simms on a number of occasions. Some may have been luck enough to see his “Monty Jython’s Scripting Circus” presentation on the conference circuit recently. If not, fear not, as he now has a developerWorks article to set you on the path to being a Jython pro!
WebSphere ESB Version 6.1 installation
Thursday, January 24th, 2008I thought I’d post a few notes based on some experiences installing a network deployment environment of WebSphere ESB Version 6.1.

WebSphere MQ Java in J2EE
Wednesday, January 2nd, 2008Thanks once again to Paul Titheridge, this time for pointing me to this technote covering the use of the WebSphere MQ Java APIs in a J2EE/JEE environment. It seems that IBM does now support the use of the WebSphere MQ Java interfaces in a WebSphere Application Server environment (check the supported software for your release) but this technote provides you with lots of reasons why you shouldn’t! The Java interfaces do have functionality that isn’t currently available in the JMS API (for example message segmentation and important parts of message grouping) but that needs to be weighed carefully against the drawbacks. JMS should always be the default option unless you have a very good reason not to use it.
Cleaning up dumps
Saturday, December 1st, 2007No – this has nothing to do with nappy changing! I’ve spent the past two weeks as part of the support team for a customer’s WebSphere Application Server environment. Although I know all the theory (I’m an IBM Certified System Administrator for Versions 5.0, 6.0 and 6.1) it’s not very often I spend long enough at any one customer to get my hands dirty. My Korn shell scripting, Jython and vi skills certainly improved rapidly during the time I was there!

Flat file custom data bindings
Monday, October 22nd, 2007Having written a very similar exercise for the Connecting Enterprise Application to WebSphere Enterprise Service Bus ITSO Workshop, it was interesting to read Rich Johnson’s article on creating custom data bindings for the WebSphere Flat File adapter. In particular, the step required to actually add the custom data binding so that it shows up in the Enterprise Service Discovery wizard is not exactly obvious.
Best Practices for Large WebSphere Topologies
Monday, October 22nd, 2007If you’re looking to scale out your WebSphere solution then this paper on developerWorks is one you must read. It provides guidelines on cell sizes and discusses when you should consider multiple core groups and how to bridge them, as well as other important considerations. Go read it!
