Hi all,

I have to access a file both in online and batch.

Online program will only update the file and the batch program will take the read the data from the file.

But its possible that before the batch job ends the online program can access the file.

Waiting for reply.

Regards,
Umesh

hi,
its possible,bcz,mvs has an options like SHAREOPTIONS(Cross region,Crosssystem).And also,by pseudo conversation,if the system wants to wait,u can do the programming like that.
anyway,i am not sure in this and correct me if you got the correct method!

VSAM SHAREOPTS(2,3) should serve your need. However, for cross-region sharing, VSAM does not ensure Read Integrity.

I have not seen any shop that uses an online file in batch when CICS is UP. I hope you don't wish to do it in production!

Hi gsnvsr,

My shop uses CICS-OPENED-FILES in batch jobs. and dozens of them. OF course they are used in read mode in batch jobs and update mode in CICS. and of course with VSAM SHAREOPTS(2,3).

It should then be okay for the business! I mentioned that I've not seen a shop doing it. Good that you alerted. Old mainframe is being used differently across different places. So, no wonder. Cheers
