Hi, I need some help in setting-up and testing a datasource as I am pretty new to JBoss. We have a clustered jboss environment that connects to a RAC Oracle Database. Wanted to find out how do I configure my Datasource and what is the best approach and where exactly do I need to make changes. Using JBoss4.2.3 How do I make sure my datasource setting is such that anytime a cluster server or RAC node goes done any transactions in between should go to completion. How can I test different scenarios are there any java programs that I can use for testing. Any help is really appreciated.
