Hi,
I'm a WO 5.4 newbie. We have a WO app that uses EOF for db access.
I believe this makes the WO inherently single-threaded.
It makes database access single threaded within one EOF stack. That
is not all of WO by any means. And one application instance can have
multiple stacks.
We have this new requirement wherein, we want to have a thread-pool
via java Executor within this WO app for non-EOF purposes to perform
some asynchronous background tasks.
Is it safe to have such a thread pool without jeopardizing the WO
app in any way?
As long as it does not touch sessions or EOEnterpriseObjects or
anything else EOF related, yes. If you want to touch sessions or EOF,
you need to be careful in how you do locking to avoid deadlock and
data inconsistency.
