Ok, so you are doing a REPRO ODS, not OFILE, like you had stated, I would try to have the VSAM file allocated with DISP=OLD and doing the repro OFILE, I believe that should guarantee you don't get the "DATASET IN USE BY ANOTHER TASK" message.
Considering you free the dataset from the CICS region, you should be able to DISP=OLD it.

Then the IDCAMS REPRO step The SYSS.HISTTEMP.BKUP is the data that will be reloaded back into the SYSS.HISTFILE. The sort step is just to put the records in correct sequence before reloading. //STEP1G EXEC PGM=SORT,COND=(0,LT) //SORTIN DD DSN=SYSS.HISTTEMP.BACKUP,DISP=SHR //SORTOUT DD DSN=SYSS.HISTTEMP.BKUP,DISP=SHR //SYSOUT DD SYSOUT=* (sort statements removed) /* //STEP1H EXEC PGM=IDCAMS //SYSPRINT DD SYSOUT=* //SYSIN DD * REPRO IDS(SYSS.HISTTEMP.BKUP) - ODS(SYSS.HISTFILE) REUSE As I stated, this runs 99% successfully. Just one or two times a year does it get the message in use by another task.
