ODP.NET

I'm just confused about how this setup works. I understand that ODP.NET is in autocommit mode by default, and any INSERT, UPDATE, or DELETE commands are committed automatically. If they fail for any reason, obviously the row(s) are not modified.

But how about sprocs? Do they autocommit as well? If so how are rollbacks handled? Do I need to explicitly create a transaction and commit/rollback? Is it best practice to commit/rollback in the .NET transaction or in the sproc itself?

As you can see, I'm just really looking for info on how these two interact. Any info you can provide will be extremely helpful.

Thanks!
