I have a CICS program accessing IMS DB (DBCTL) . When two transactions accessing the same PSB (Schedules the same PSB) is invoked, one of them goes thru and the other gives me a staus code of 'TE' . (both transaction corresponds to the same CICS Program)

Why am I not able to schedule the same PSB in two different transactions concurrenlty? If it is not possible, then is there a solution?

I want high concurrency since its an online program. Can you please tell me a work around for this?

TE is a PSB scheduling error, more info is needed to diagnose the issue
working with Your support will solve the issue faster than asking on a forum

Enrico! I have gone thru theses manuals. They have been of no help for me. I know why we get a 'TE' . The problem here is when one transaction schedules a PSB another transaction is not able to schedule the PSB at the same time.

could this be a problem with the PGM or with the DRA setup?

PSB is defined. I am able to use it. The support says there is no problem on their side. They say the program has to handle it.

what kind of support do You have ???

Quote:
If multiple CICS transactions or BMPs are to schedule a PSB concurrently, the APPLCTN macro for that PSB must specify SCHDTYP=PARALLEL. If you do not specify SCHDTYP=PARALLEL, only one transaction at a time will be able to schedule a PSB. You can change the SCHDTYP of a PSB using the online change process and the /MODIFY command, which you enter at the DBCTL console.


and IIRC You are going to get a DHTE CICS abend which corresponds to a TE return code
but everything as usual, depends on Your customization
so as I said before have Your support investigate better!

Thank you Enrico! SCHDTYPE=PARALLEL worked.
