AIX: 4.3.2.0
RDBMS 8.1.6.3
We have two instances on two different servers. There is replication from
serverA to serverB. Periodically SID_A starts filling its alertlog with
"ORA-00020 Max sessions" errors. It is reporting a failure of the replication
into SID_B. It is SID_B that has the max sessions error (this is verified by
connection to SQLNET on both instances). A
At the same time the listener on serverA freezes up with anywhere from 400-600
ESTABLISHED connections against port 1521 - the SQLNET LISTENER.
I'm capturing TNSPING times from server_B to SID_A. I'm also capturing a
session count every 2 minutes. In my opinion the session count starts going up
about 20 minutes before the TNSPING time get very long and ultimately stops
returning.
We've had a TAR open for weeks and Oracle cannot solve it.
Any ideas for further troubleshooting?
