IIRC, when you issue a rollback and there isn't actually anything to be rolled back, then the 'transaction rollbacks' value in v$sysstat will not be incremented - only the 'user rollbacks' will be incremented. Someone please correct me if I'm wrong. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Ken Payton Sent: Wednesday, December 28, 2005 7:00 AM To: bnsarma@xxxxxxxxx Cc: Oracle-L Subject: STATSPACK - Rollback per transaction % You might want to check your application connection pooling. A connection pool might rollback a pre-established connection before returning it to the pool, regardless of whether something is being rolled back or not. . . . In this case, since you do not actually have anything to rollback you are probably fine. Kenny Privileged/Confidential Information may be contained in this message or attachments hereto.
