Can't remember where I copied this from, but I believe it came from metalink. I don't have a version associated with it, so things might have changed in v9.
HTH Barb Public vs. Private Rollback Segments ------------------------------------ A common misconception about `Private' rollback segments is that they are segments reserved for a particular use or a particular transaction. The only difference between Public and Private rollback segments is in relation to the Parallel Server Option. A public rollback segment can be acquired implicitly by any instance in a parallel server environment. A private rollback segment must be explicitly acquired by a particular instance using the rollback_segments parameter. If not using OPS, the difference between the two is insignificant. > ---------- > From: dist cash[SMTP:[EMAIL PROTECTED]] > Reply To: [EMAIL PROTECTED] > Sent: Thursday, October 17, 2002 9:18 AM > To: Multiple recipients of list ORACLE-L > Subject: [Q] Public and private rollback segment? > > > > > We have ORACLE 8.1.7.4 running on NT.
