Tuning

Postby gali prasad » Tue Aug 03, 2010 12:43 pm

Dear all,

I have following SORT job whereas Input file has records of around 62,000 and splits into individual records based on type
We are going to increase file size to 30,00,000 records.

//STEP EXEC PGM=SORT
//SORTIN DD DSN=Input file,
// DISP=SHR,BUFNO=60
//OUT1 DD DSN=&PTEF..NVS.PTEFA391.CORR.DIV1,
// UNIT=SYSDA,
// DCB=PRD.LRECL150,
// SPACE=(CYL,(20,20),RLSE),
// DISP=(NEW,CATLG,DELETE)
Similarily OUT2,OUT3,,,OUT20...


Please can anyone let me know if there is a way to reduce CPU time and my application relates to SYNCSORT.
Thanks a lot

Please identify which release of SyncSort for z/OS you are currently running. Please also show us your control cards. How can we help you tune your application if we cannot see what your application is doing?

I think it would be most helpful if you could send me the complete job listing (JES Job Log, JCL and SYSOUT messages) from the original run. Feel free to send it as a text attachment to alissa.margulies@syncsort.com and I would be happy to further assist you.
