So the number 23136534 is a latch number. I would think additional D GRS commands could help.
D GRS,ANALYZE,LATCH,DEPENDENCY,DETAIL Would be helpful in this case. Did you have any jobs running that were backing up the catalog(s)? Who was the owner of the Enqueue (D GRS,C) What latch was in play (D GRS,ANALYZE,LATCH,DEPENDENCY,DETAIL) There are a few other D GRS commands that might be helpful with these conditions D GRS,ANALYZE,BLOCKER D GRS,ANALYZE,WAITER D GRS,ANALYSE,LATCH,BLOCKER <-- the commands book may be wrong, Might be ANAYLZE. I always start with the OWNER in a D GRS,C command then see how long it is held. And work down from there.
