If we write the bellow connection URL it works fine, without providing Server=SHARED. <connection-url>jdbc:oracle:thin:@(description=((address=(protocol=tcp)(host=mana-jb)(port=1521)))(connect_data=(SID=testdb) I would like to know how to find out the JBOss is using Shared Server connection pool? What are the approaches we need to test to make sure the Database connections are SHARED?
