My UNDO utilization is very high and most of the undo is eaten by (CJQ0) process, how can I find which JOB in this queue is highly utilizing the UNDO.

Thanks

How many times will you repeat the same question?
Don't tell me there was a problem with your browser between the first and last topics there was 1 hour.

Hi Micheal,

I am telling you, there was a problem with the browser.
Anyways, I have already checked the JOB details there is no other job running except the routine ones.

This type of issue has popped up first time in this database.

Pls suggest!

How are you determining that the UNDO is being used by this process?

>My UNDO utilization is very high
You can't have high UNDO without high REDO; as they are cojoined twins.
What is size of REDO & how often do they switch?
