Subj: | | Re: Sessions holding locks after query completes? |
|
From: | | McBride, Michael |
Well, I tried a simulation with a blocked session using a Cognos user (X) in an Impromptu query session, and ETL user (Z) requesting an
EXCL lock this is the results....
When X runs impromptu report, access lock is granted
When Z asks for exclusive lock, access blocked....
When X report is completed, residual blocking access lock remains
When X runs another report, residual blocking access lock remains
When X opens another catalog, residual blocking access lock remains
When X closes ALL catalogs, residual blocking access lock remains
When X terminates impromptu application (in Windows), access lock is released, Z is granted EXCL lock.
