I deleted a large volume of data then tried to rollback and had to kill the session. How would oracle 10.2.0.3.0 handle this ?
I deleted data from 13 tables, one of which deleted 4.2 M rows. So I killed the delete (in Pl*Sql Developer). The kill of my query worked and then I clicked the button to rollback, at which time the Pl*Sql Developer window froze up.
So I killed the Pl*Sql Developer window via Windows Task Manager, but the session was still running in Oracle. I then tried to kill the session (twice) via Sql*Plus using "exec manage_sessions.kill ('SID','SERIAL NUMBER')". That did NOT kill the session. In the morning it was finally gone.
After some initial triage, it looks like the deletes were NOT committed, as I had hoped was the case.
But I just wondered how Oracle would handle this.
