Home -> Community -> Mailing Lists -> Oracle-L -> RE: OT RE: 24 x 7 on NT?
Mark,
You list ALL the SQL the blocker has or only the SQL that is doing the blocking? I've been looking for a tool that does the latter for a long time and never found one that can identify the statement, if other SQL has happened in the meantime
