Hi ALL,

If I do a LISTCAT on a production VSAM file (whilst it is been used by a job), would I face any issue such as abend or hold issue? I tried this in test but in test I don't have such a huge file that keeps on updating/reading the VSAM file for few seconds which I require to run listcat on vsam.

In my opinion, it shouldn't throw any issue or error.

Please advise.

Regards,
Mohit

The answer to your question depends upon the VSAM data set -- and specifically how the SHAREOPTIONS are set. For most systems and most VSAM data sets, the answer is that there would be no chance of hold or abend issues. On the other hand, the statistics displayed might not be accurate if the VSAM data set is open by other address spaces (such as CICS).
