Hello All,

I want to set change the default parameters of statistics collection some specific schemas as per vendor recommendation.Instead of disabling auto stats job and creating a cronjob to collect stats.

i am just plannning to use SET_SCHEMA_PREFS(which i havent used before) and change following params for those schemas.

METHOD_OPT       => 'FOR ALL INDEXED COLUMNS SIZE AUTO',

GRANULARITY      => 'ALL',

CASCADE          => TRUE,

NO_INVALIDATE    => FALSE

version -  Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

As per ..How to Change Default Parameters for Gathering Statistics in Oracle 11g or Later (Doc ID 1493227.1)
