This is great information. Thank you so much. How do you turn off the trace? also are there any commands to stop the error from occurring? for example flushing the shared pool?

Hi Tanel:
How do we dig deep in to the output once we run the head dump. In your example, you have explained about KGL handles for library cache handles, KGR PO for dictionary cache parent objects etc.
How do you go further from this? I think I have two questions
(a) How do you know KGL handles = library cache handles. If I get a different output how do I interpret what that handle is being held for?
(b) Once you get information on (a), how do you proceed further to get to the acutal application or object causing the issue?

Thank you
Kumar
