In this example you end up on the same instance - and the original SID with the ORIGINAL SERIAL# is still alive. What was the status of the old session ? ACTIVE, SNIPED, KILLED etc. ? And what was the state and event ?

This looks a little unexpected - buggy even - but are you using any new(-ish) features that might be related; the first one that springs to mind is database resident connection pooling.

Subject: Fwd: Session migrated to another instance

Testing today
Curious. My SID has changed from 1234 to 6789 sometime between 09:56 and 11:28. I've verified that no instance in the cluster has been restarted. I had issued NO commands from this SQLPlus session. The TNS connect-string I use is a simple connect string specifying the SCAN address.

So, my session has been migrated maybe from instance 1 to instance 2 or 3 and then back to instance 1 in that 1.5 hours (while it was idle) ? Was it migrated because the service was migrated ? I think I can discount server-side TAF because no instance was restarted.-- http://www.freelists.org/webpage/oracle-l Received on Thu Jun 20 2013 - 19:13:32 CEST
