Presentation slides of Weblogic server 9.0

Nice slides of a presentation of Weblogic server 9.0 made duringJavapolis 2004 are available on-line.

I have discovered some new features like deployment planswhich can be useful when you need to support manyconfiguration environments: test, integration, qualification and production without having to unjar and modify the deployment descriptors.

Some new features are purely technical and useless : like the usage of XMLschema for the config.xml or the usage of log4j as the logging framework.

For developers, the integration of Webservices Metadata looks nice.BTW, this feature is more tied to the usage of J2SDK 5.0 metadata.

Many new features on the JMS stack look promising and make the Weblogic JMS server more attractive as a MOM on its own like Websphere MQ or Sonic MQ.See ( you need to register)

BTW, merry christmas !

JRockit rocks on IA64

I did some benchmark on a web application which runs on Weblogic8.1 sp2. Weblogic was installed on a 4 IA64 CPU Linux server .
The benchmark between the Sun JVM 1.4.1 for IA64 and the BEA JRockit providedwith Weblogic showed that the application ran 10x times fasteron JRockit. The ratio was even higher with more than 50 virtual users.

I couldn't even believe it. I thought I had done mistakes trying to tunethe Sun JVM with the -XX options but no the results were the samewithout the -XX options. I haven't figured outwhy the Sun JVM ran so slowly… But if you need to run Weblogicserver on IA64 give JRockit a try, it's really worth it.

To be honest, the Sun JVM 1.4.1 for Itanium 64seems to be a beta one (java -version gives build 1.4.1-b21) and the JRockit JVM is the only one supported on IA64 by BEA. So the comparision was obviously biased. By the way,i'll do some tests with Weblogic 8.1 sp4 with a JVM 1.4.2
