John,

Thanks for this advice. I will try to get this data tonight on the updated version.

We do not have the old version around anymore to try this out.

If you have access to the ANALYZE scripts, could you modify it to obtain _what_ this session is waiting for and how much (from V$SESSION_EVENT) as well as look at V$MYSTAT to determine the volume of work. It would be a good
idea if you can back-test (is there such an equivalent for back-port?!) on the older environment. This may give us some clues.... I am not aware of ANALYZE changing, although the CBO decisions between the two versions (given
the same stats/values) may differ.
