Yesterday I headed down to Bedfont with a car load of IBMers to present at the WebSphere User Group meeting. I was presenting an update covering new function in WebSphere ESB and Process Server 6.2. After days of pulling together slides from all the various product architects I ditched my pitch in favour of a few minor modifications to an excellent presentation from one of the worldwide tech sales team. Obviously I know the WebSphere ESB material well enough but this was a good opportunity to brush up my knowledge of the new function in Process Server. I also went to a couple of interesting presentations on OSGI, JAX-RS and JPA as well as my colleague Brian Hulse’s detailed presentation on the Service Gateway and Policy support in 6.2. With attendance down on usual, I felt the large number of parallel tracks led to smaller than desirable audiences for many of the presentations. It was also a horrendous drive back home along the M3 through torrential rain.

Wednesday, March 4th, 2009Security Bulletin for WebSphere Application Server
Tuesday, February 10th, 2009I now try to avoid just re-posting material from developerWorks and other IBM sources but this one is worth highlighting. IBM is now publishing a list of risk assessed security vunerabilities for WebSphere Application Server.
WebSphere MQ non-ASF in WAS
Wednesday, February 4th, 2009Application Server Facilities (ASF) are the part of the JMS specification originally designed, amongst other things, to allow application server’s to retrieve messages for delivery to message-driven beans. Now WebSphere MQ’s ASF implementation had one significant flaw when it comes to multiple consumers pulling messages from the same queue. Each consumer was effectively browsing the queue looking for suitable messages and, when they found one, they then attempted to take a lock in order to consume the message. Unfortunately, inbetween the browse and the lock there’s a good chance that another consumer would have nipped in and stolen the message. This inefficient behaviour meant that you were unlikely to see linear scalability when adding multiple MDB consumers to a deep queue. As a result, some customers have switched their WebSphere Application Server listener port service to use non-ASF mode (the custom properties required for this can be found in the InfoCenter). This use a standard message consumer to poll the queue for messages – the downside being that you need a separate thread for each consumer.
WebSphere ESB 6.2
Friday, December 12th, 2008One of the disadvantages of being back in development is that much of my work is confidential. As the quantity of technical posts on here recently demonstrates – this is not conducive to blogging. Thankfully Version 6.2 of the entire BPM stack became generally available today so the flood gates have opened. developerWorks already has articles covering the new functionality in WebSphere Integration Developer and WebSphere Process Server so, rather than just relisting the features, I’m going to provide a slightly more personal view, focussing on the new content in WebSphere ESB.
10 years on
Wednesday, November 19th, 2008Being presented with my “10 year pen” at a departmental meeting on Monday seems like a good excuse for a bit of a retrospective on my career with IBM…
New WebSphere blogs
Wednesday, September 24th, 2008There has been a recent push to get more of the WebSphere development team out in to the blogosphere in the run up to the release of V7 of the Application Server. The standard form seems to be to advertise new blogs on the WebSphere Community Blog. So far there is one covering WebSphere and Java Persistence, and likely to be of particular interest to readers of this blog, one on WebSphere and Messaging. Note that the latter doesn’t cover WebSphere MQ (see this blog if that’s your area of interest) but rather the default messaging provider in WebSphere Application Server. Expect to see lots of good material on some of the new features and make the most of the chance to interact with the development team. Whilst on the subject of new blogs, if DataPower is your bag then you can read all about a forthcoming book from some of my ex-ISSW colleagues here.
Messaging Engine Startup Problems
Thursday, September 11th, 2008Another heads up for some Service Integration Bus education. On 17 September there is a free webcast entitled Messaging Engine Startup Problems given by Level 2 service and followed by a Q&A session. You can see a list of all the upcoming webcasts or, to receive information about events such as this, along with information about publications and support issues, sign up at My Support.
Update: the replay for this webcast is now available.
Changing jobs
Saturday, September 6th, 2008No – I’m not about to leave IBM but, after nearly four years in IBM Software Services for WebSphere it’s time to hang up my travelling bag and, as in all good resignation speeches, spend some more time with my family. I’ve really enjoyed the chance to work closely with customers on some very interesting projects during that time and in many different countries (let’s see, from the top: Norway, Sweden, Finland, Denmark, Germany, UK, Switzerland, Italy, Spain and the US). I have also had the opportunity to work with some very talented and knowledgeable IBMers. I can’t really claim to have enjoyed the travelling – one business hotel looks much like another after a while – but for some reason customers insist of the consultant coming to them rather than vice-versa! The real killer though is not knowing where you’re going to be next week or perhaps even tomorrow.
