DOAG Konferenz 2009: Impressions Day 2

As promised, today my impressions of yesterday (confusing, I know). Clarification: This is about Wednesday, November 18th. I’m still at DOAG Conference 2009 in Nuremberg.

DOAG Konferenz 2009: Impressions Day 1

Oracle: Tracing of another session

I simply love 10046 level 12 traces. I described session tracing based on a logon trigger quite earlier, but some situations in real DBA life need this trace event switched on for a session other than my own AND for a short peroid in time (with no need for the connected user to log out). […]
