How to check a jdbc configuration

[agorka]

Hello
I've started with JBoss AS as administrator. I configured the datasource according to doc. I set also a min pool, new connection sql (select 1 from sys.dual). But I can't see any connection from the JBoss in the database level (It is Oracle). Should this connection automatically appear in the database ? or should I run something?

Connections are lazy-loaded - none will be made until an app requests one, then min connections are made.

Thanks, is it something I can do to force JBoss to open the min connections? I have none application yet.

Write a service with a startup class and have it access the database. To write a startup class, see http://www.jboss.org/community/wiki/CreateAStartupClass. That wiki page is rather sparse, but the example MBean should get you started.

Thank you, i'll try to do it.
