RE: ora-4031 & large_pool

Rachel Carmichael


we run weblogic as well, so I'd bet you are running XA...

check into large pool. We found it by accident, the symptom was that
none of the XA connections could actually connect to the db. So we
rolled back the init.ora changes, even though the other DBA kept
insisting there was no way his changes could have been the problem.
Changes gone (one of which was changing the large pool size) and
connections miraculously were made. He insisted it was just "the order
in which things were shut down and restarted"

Oh yeah, one of his changes was to increase the db_cache_size "because
the BCHR was at 70%"

Yes I screamed over that one. And I keep screaming. And he keeps
ignoring me.

I wonder sometimes if the reason they don't listen to me is because
"I'm a girl"
