I am running a query against DBQLogTbl and soon as I do, I see that the ?user DBC is being blocked by my ID. More details from PMON reveal that lock requested by "selected session is Lock mode :read, status : granted".
Against DBC session info details I see this "Artificial session , blocker information for all internal DBQL and TWM requests"
Just what is this session and any explanation. I've never seen it before . Is it something done by TWM
