Yes, it would not work if there is any explicit or implicit commit, including all DLL statment.

It will only work for long running DML statement (with no commit in the=

middle).

Thank Alex for making this point clear.

No, there is no guarantee that a rollback segment can be delicated to a=

specific user only.

Even the set transaction thing cannot forbid other user from using that=

rollback segment.

But there is a trick that you can use to get what you want.

Right before you issue that set transaction thing, bring the rollback segment online, then after that user put in the statement. Take the rollback segment offline.

Notice that the rollback segment is on the OFFLINE PENDING status. It w= ill
only go offline after the active transaction is done. But at the mean t= ime,
no new transaction will grip this rollback segment.

All,

Is there any method of tieing an individual user to a rollback segment = to
the exception of all others. I know about the set transaction thing but=

what
I want is to avoid other users on the db using the one created for a specific task.
