Database pool only showing half the minimum connections allo

[daorriss]

Perhaps I'm misunderstanding something here, but I have the following configured for my oracle connection pool - 20 for a minimum pool size and 100 for a max pool size. However the DBA is only seeing 10 connections being made from JBoss. What's going on here??. (code included - trimmed for brevity). TIA!

OK after finding the section in the Administrators guide on this. I find that connections aren't created by default until they're needed. OK.. but what if I want to initially create that pool of 20? Is there any way to configure this?

This element specifies the minimum number of connections a pool should hold. These pool instances are not created until an initial request for a connection is made.
