GATHER DICTIONARY / SYSTEM / FIXED OBJECTS STATISTICS & IO CALIBRATION : PROCEDURE OF ROLLBACK

edited Apr 15, 2014 4:30AM in Database Tuning (MOSC) 1 commentAnswered

Hi ,
I have to gather dictionary , system and fixed objects statistics for performance reasons by using :
DBMS_STATS.GATHER_DICTIONARY_STATS
DBMS_STATS.GATHER_SYSTEM_STATS
DBMS_STATS.GATHER_FIXED_OBJECTS_STATS

Also perform an IO calibration by using DBMS_RESOURCE_MANAGER.CALIBRATE_IO
My question is :
Is there a procedure of rollback for each operation ?
Best regards.
GD.

Howdy, Stranger!
