So, how do you experience/see this corruption? ORA-600’s?

Perhaps the jobs are not actually corrupting the index but they are just victims, the first ones who access a corrupt block.

With corruptions, the sequence of things to do is roughtly this:

1) check OS syslogs to find out whether any hardware issues are reported. You may also ask storage admins to check their sources about storage.

2) run dbverify or RMAN test backup to detect the scale of corruptions in the database

3) if this truly is an Oracle job which corrupts some blocks then its possible to find out more details using logminer, log dumps etc, however I would check point 1/2 first.

Hi Tanel,

Just have a question, is there a way to identify a process that causes certain indexes to get corrupted, All I do know is that my client is running SAS jobs which calls stored proc’s, but not sure which process is causing the pains.

I heard about you from a friend who had attended your seminar before. My friend said your seminar is very helpful for DBAs.
And I found the scripts you privoded here is also very helpful.
Thanks a lot.

One was related related to a problem that was showing up in the alert log every morning at around 5am. Rather than taking the ‘old’ approach of trying to look around the DB (early) in the morning, I just set an event to have the SQL dumped the next time the error condition occurred. I passed that along to the development database engineer so they could investigate further. I followed the systematic approach. (Was didn’t have to get up @ 5am in the morning!)

Awesome! Good to hear that :)

Just out of curiosity – what kind of problems did you troubleshoot?
