(Doc ID 1549503.1)
Last updated on FEBRUARY 01, 2019
Applies to:Siebel CRM - Version 126.96.36.199  and later
Information in this document applies to any platform.
In the white paper 'Performance Tuning Guidelines for Siebel CRM Application on Oracle Database (Doc ID 781927.1)' it is recommended to use - DBMS_STATS.AUTO_SAMPLE_SIZE.
In the code itself, there is a comment:
-- if 11g then use auto sample size instead (ok only if gathering with no histograms)
-- this part has been eliminated due to bug 10174050: AUTO_SAMPLE_SIZE is causing some histograms to miss important buckets
--IF l_rdbms_release >= 11 THEN
-- estimate_percent := 'DBMS_STATS.AUTO_SAMPLE_SIZE';
Which is the right description of sample size needed in Oracle 11g for Siebel.
