Not sure about 1 & 2, but I believe v$db_object_cache is what you want for #3.

Subject: Which packages to pin


Oracle 8.1.7.4 - Aix 5.2.

As a cure for the ORA-4031 errors which we are getting (up to 5 per
day), I am looking at the possibility of pinning some of my stored
procedures and triggers.  Looking at the Toad   Pinned Code screen
combined with what I know about the application gives me a good idea of
what parts of the application code should be pinned, but I do have some
questions:

1.  Are triggers normally candidates for pinning?  (Toad lists them on
its screen, so I infer that they are.)

2.  Should I also pin some of the system packages which are displayed on
the Toad Pinned Code screen?  (e.g. DBMS_OUTPUT, STANDARD,
DBMS_STANDARD, DBMS_SQL...)

3.  Which of the dynamic views (V$... ) lists the packages, stored
procedures, and triggers currently in the shared pool?

Thanks,
Peter Schauss
