Hi Ron and all, I have captured the strobe report for the full run of the job. I will try to send it to later. In addition to strobe, i snapped the below statistics of the job from Mainview. The report shows that the EXCP and the SSCH counts are almost equal. I am of the understanding that if SSCH count can be reduced it can help in CPU reduction. Could you please provide some direction on to reduce the SSCH count.
FYI,I also tried with data CISZ of 18K, 30K and 32K. 18K and 26K look to show almost similar performance of taking 6.5 CPU minutes for the test files with 32M records. 26K CISZ showed the least EXCP counts amongst all..
