Thanks Laurentiu for responding. Please find the below link which contains
the sql monitor report. This was taken 5 minutes after it was started.The
SQL ran for more than 5 hours and hence we had to cancel that. I don't see
SQL in RTSM history too. I am not sure how far this will be useful.

Hi All,

We have a SQL performance issue and as per ASH the SQL is spending most
of its time on CPU. Not sure which operation is taking more time.  Can
someone guide me how to troubleshoot what is causing the SQL to spend time
on the CPU?
