Atomikos Forum

We are working with multiple environments, but one issue pops up consistently with Oracle 11G RAC systems.  Not on 10G, or non-RAC at all, only RAC 11G.

Interestingly, the data is actually committed - I can open up Oracle and see it there.  Yet, we get hanging during the commit operation, with this stack trace being printed over and over in the log:

Does this sound like a familiar situation ?

Only the first node/branch is committed.  The rest become pending transactions upon killing Atomikos due to the hanging.  So part of the XA transaction commits, the rest are left pending.

Actually, the first *two* branches commit, while the rest become pending transactions.

Very strange.

Is there any other exception info in the tm.out?

Thanks
