DBMS_AUTO_TASK_IMMEDIATE.GATHER_OPTIMIZER_STATS DOESN'T GATHER TABLE STATISTICS

in SQL Performance (MOSC) 9 comments

Dear ，

my database is Oracle Database 12c Enterprise Edition Release 12.2.0.1.0. When i run :DBMS_AUTO_TASK_IMMEDIATE.GATHER_OPTIMIZER_STATS, i find all the tables LAST_ANALYZED date is not updated.

I find all the DBA_TAB_STATISTICS's STATTYPE_LOCKED is null.

any setting can fix it?

Thanks.

Howdy, Stranger!
