Recovery from database faults

[nicknewman]

I have JBoss (3.0.7) working fine, but I have been asked a question about how it recovers from database faults. I hope someone can help!

If I try to start JBoss without the database being available it (of course) throws exceptions. But can it recover if the database later becomes available? Is there something I can do to help?

Or if JBoss is running and the database goes down for a while, will JBoss recover when it comes back up?

Thanks.

I should add that based on limited tests it seems NOT to recover if the DB is unavailable at startup, but DOES recover if the DB is lost AFTER startup.

But limited tests can be misleading, and there may be settings that I'm unaware of. So I'd still value other input.
