My system prior to batch cycle Closes the CICS files and Deallocates them using the IPCP utility. IPCP Utility is just same as CEMT commands.

1. CLOS DB xyz
2. DEALLOC DDNAME=xyz

My question is if we Close the files, so why do we need to Dealloc the files?

Is it because until we deallocate the CICS files, we will not be able to REORG the respeactive files in Batch environment.


Thanks,
Chirag

When the files are closed, they are still allocated to the CICS region and can be reopened by any program accessing them. If they are allocated to CICS, they cannot be allocated with exclusive access to a batch job, hence they cannot be deleted or reorganized.

consider using different vendor product >> www.batchcics.com
and control close / opening of files from within your batch COBOL
program.
