Subject: isolation levels
Hi list.
There is an isolation="serializable|committed|uncommitted|repeatable_read"
attribute for <entity-deployment> that isn't very clearly documented.
Does anyone know what these levels do (or where I should look to find
out)? In particular, on one finder method (findByParent for a tree-based
data structure) I get a deadlock (in the app server, not the database) if
the finder method is fired twice in rapid succession, and I'm wondering
whether changing the isolation to "repeatable_read" might cure this?
Or am I barking up a completely inappropriate tree?
Thanks,
Dan/tastapod
