We have a PeopleSoft system (Finanacials) that is just moving into
production. Some of the conversion and data entry stuff was running slowly
so I peaked at our system and session wait events (as well as looking at
some recent history with statspack). There was  a huge amount of time_waited
for 'library cache load lock'. Never came across this one before. According
to the Docs, it is a lock used to load an object into the library cache (you
don't want the same object loaded more than once). I am trying to find more
information so I can debug this. Of course the problem isn't there today
(other modules are being worked on. Maybe that is why).

Just trying to be ready when/if this happens again. I'm thinking a 10046
trace might give me some object information about what is being
loaded/locked. Metalink suggests taking a systemstate dump (though they seem
to mix up 'library cache lock' with 'library cache load lock'. Don't know if
the same tracking techniques work on both.).

Anybody else see this before? Suggestions on what to do if it shows up
again?

Thanks.

Henry
