General Information

Library Note

Morgan's Library Page Header

ACE Director Alum Daniel Morgan, founder of Morgan's Library, is scheduling complimentary technical Workshops on Database Security for the first 30 Oracle Database customers located anywhere in North America, EMEA, LATAM, or APAC that send an email to asra_us@oracle.com. Request a Workshop for your organization today.

Purpose The Oracle documentation states: "SQL*PLUS command file to create statistics package." At one time that was probably an adequate description. Now, with AWR, the more accurate definition might be that this is a PL/SQL package of utilities support StatsPack and unfortunately also named StatsPack. For information about StatsPack functionality, which was the original AWR and which can still be deployed and used for much of what AWR does ... one of the largest distinguishing characteristics is that StatsPack does not require additional licensing such as Diagnostic and Tuning pack.

We strongly advise installing the PERFSTAT schema and objects in a PDB to avoid having to replicate the PERFSTAT tablespace in every PDB.
