Re: Library Cache Lock

Thanks for the note - I think it may have been
your bug that I found on metalink; your description
sounds familiar.

I'm hoping that I get called back to the site, as
it's hard to find interesting problems with things
like the library cache - but at present I'm following
it up for curiosity, rather than necessary.

If I get another shot at the site, I'll get back to you
if I find anything interesting.

Subject: RE: Library Cache Lock


We have had many similar situations where we had lib cache locks/pins on a
_table_ - did you notice that all the waiters were queueing up behind
another session that was 'hanging' on a 'row cache lock'? (for this happened
consistently in our siutation). This is a fairly large Oracle Apps 11.5.7
installation - this occurred in a schema that has a number of partitioned
tables and MVs. It is possible that there were partial refreshes of the MVs
occurring at the time of the problem.

In any case, we had a large reduction in the occurrences when we upgraded
from to, and obtained another reduction when we re-arranged
and serialized some background jobs (Apps concurrent managers). A TAR with
Oracle was useless - we were sent on a runaround and passed from one to
another until we dropped the issue (since the pain went away). I did take
some system dumps, but they might have been purged (I can dig around).
