I tend to consider myself more of an application architect than an infrastructure expert when it comes to WebSphere Application Server and this is exemplified by my total lack of knowledge about WebSphere’s proxy server. Although shipped as part of WebSphere Application Server Network Deployment I have to confess to only having a rather fuzzy idea about its capabilities. It was therefore good to read Erik Burckart’s column reviewing the capabilities of the product and discussing where and when it may be used.

WebSphere proxy server
Tuesday, June 19th, 2007WebSphere and Oracle RAC
Tuesday, June 19th, 2007The question of Oracle RAC support for WebSphere Application Server has come up with a number of customers I’ve worked with and Soloman Barghouthi has always had the answers. So, when teamed up with my ISSW colleague Deb Banerjee and WBI Chief Architect Eric Herness, this developerWorks article has to be the definitive statement of using Oracle RAC with WebSphere Process Server.
Real-time Java
Tuesday, June 19th, 2007Having plugged my mentor’s musings it seems only fair that I do the same for my mentee, Andrew Hall. Andrew currently works in the Java 5.0 service team but in a previous role in test he became intimately acquainted with the WebSphere Real Time product. I mentioned the Metronome Garbage Collector following Gerry Cuomo’s demo at the WebSphere Service Technical Conference. You can read all about it (along with much more) in the developerWorks article to which Andrew has contributed.
My Tasks
Tuesday, June 12th, 2007The WebSphere Application Server administrative console isn’t always the easiest beast to navigate and I often find myself having to repeat those five clicks to get back to the page I was just on a moment ago and wishing that there was some sort of bookmarking support. I’m therefore surprised I’ve failed to spot the My Tasks support in Version 6.1 before, which goes at least part of the way to solving that problem.
Performance Tuning Guide
Tuesday, June 12th, 2007The WebSphere Business Integration Performance Tuning Redpaper has now been updated to cover Version 6.0.2 of WebSphere ESB and Process Server. The information in this paper comes from the product development performance teams and, if anyone knows how to squeeze the last ounce out of these products, it’s those guys.
Service Life Cycle
Monday, June 11th, 2007Arnauld Desprets and Laurent Rieu are two of IBM’s European leaders in the SOA governance space so it’s worth reading their developerWorks article on implementing and enforcing a service lifecycle with WebSphere Service Registry and Repository. A reminder though that WebSphere Integration Developer isn’t the only mechanism to create SACL and OWL files.
REST and Web services in WSDL 2.0
Saturday, June 9th, 2007REST versus SOAP is one of those holy wars it doesn’t pay to get too passionate about. Each has its own merits, for example the simplicity of REST versus the transport neutrality of SOAP. It was therefore interesting to read a developerWorks article that describes how the HTTP binding in WSDL 2.0 enables REST-style interactions for Web services. As the author indicates, this support doesn’t let you do everything you could with a truly REST based service but it’s good to see the WS-* spec writers taking the move for simplicity on board.
JAX-RPC Web Services
Saturday, June 9th, 2007There is an interesting developerWorks article covering the JAX-RPC Web Services support in WebSphere Application Server Version 6.1. It demonstrates how this support alone can provide some of the benefits normally associated with an enterprise service bus, namely location transparency (WSDL endpoints can be overridden in the administrative console) and protocol transparency (SOAP/HTTP, SOAP/JMS or RMI/IIOP). As the article goes on to state, the combination of WebSphere ESB and Service Registry and Repository can give you much more dynamic behaviour when trying to achieve the first of these but if all you need is the ability to modify endpoints when, for example, moving from the development environment in to production, then this may suffice.
