Issue/Introduction

Question about NJOBS during RESTORE CAIJTRK.

CADC006W WRAP-AROUND HAS OCCURRED DDNAME=CAIJTRK

We have a VSE machine that runs up to 2500 scheduled jobs at the end of the month.
Do we have any benefit relating to the
wrap around if we use a higher value of NJOBS during "RESTORE CAIJTRK"? 

Do you suggest using NJOBS=2500 ?
Or, NJOBS=4000 ?

What do you recommend ?


 

Environment

SCHEDULER VSE
CA Scheduler 7.3, Service Pack 0304
Operating System: zVSE 5.2
 

Resolution

We recommend a higher value than 2500 to allow a cushion before reaching the end of the tracking file data area.

To determine a good value we would need to know how many jobs are run between REORGS
and how often do you do a REORG of the tracking file? 

Additional Information

Two other factors are the # of jobs you run between REORGS and how often you do a REORG of the tracking file.
