GATHERING STATISTICS For most of the objects, gathering stats once a week is enough If there are volatile objects, gather stats only for those objects Supported ways: using Gather Schema Statistics concurrent program or FND_STATS Don t use DBMS_STATS directly for EBS objects (because FND_HISTOGRAM_COLS) Consider using GATHER_AUTO option Modification threshold defaults to 10%, but can be changed Stats will be gather on objects that have %DML > 10% of (total number of rows) Consider using Auto Sample Size In DB 11g and 12c, Auto Sample Size is the default Uses new hash algorithm that Oracle says that is almost as good as 100% sample size Remember of Data Dictionary and Fixed Objects stats Review: Best Practices for Gathering Statistics with Oracle E-Business Suite (Doc ID 1586374.1) Copyright 2016 Accenture All rights reserved. 11
