I can get the Maxisize information using:

./twiddle.sh get jboss.jca:name=CatalogDB,service=ManagedConnectionPool MaxSize
MaxSize=200

I can also update the jboss.jca:name=CatalogDB,service=ManagedConnectionPool MaxSize parameter using the JMX web console.

But I cannot do it with twiddle, how to fix it?

Any help is highly appreciated,
Thank you,
Zhenzhen

I just tried it, works for me.

Which version of JBoss AS? Which version of the JVM?

[zhenzhen_liu]

JBoss Version is jboss-3.2.7RC1.
JVM is jdk1.5.0_03

I realized it might be a version problem. But is there any other way to solve it except installing a new version. Because someone else installed and modified it and I dont want to recompile it and mess up with it.

Thank you very much!
