Speed up your Gather Schema Statistics process

Well , again to get the best of performance in the system , we had observed that the gather schema statistics , with time , had started to take almost 15 hours. The DB size was about 1700 Gb growing daily by 4-5 GB. 

Most of us generally run Gather Schema Statistics on the weekend with gather option , however we are not aware of the gather_auto option. Gather_auto is the new and recommended way of running the GSS in the EBS system. 

Have adopted the same .Requires a patch :

16410424:R12.FND.B as per Note 1586374.1. 


Post application of this patch , the GSS now completes within 7-8 hours on weekends. 

And yes , since we are always worried about performance , this did not cause any performance harm. None of the end users came back with any issues.


Cheers
