Forgive me for asking what is probably a simple question, but we are having performance issues with our messaging cluster, specifically on the database side of things. I am trying to see if I can improve performance by tuning somethings and I am looking for a way to set the number of statements included in a batch update. I have the following set in my persistance-service.xml: true Is there an additional parameter to change the number of statements in a batch? Or is there a setting on the datasource to change this? Also, what is the default number of statements in a batch? Thanks for any help you can provide. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4168657#...
