Hi,

Can I invoke a CICS transaction using REXX.


Thanks in advance,

Ramkumar.

Ramkumar,

I worked on CICS for a very short time, that too longggg back...So, I am not sure if this is possible. But just a guess.

When we use TDQs to invoke a JCL from CICS, couldn't that be leveraged to do the reverse operation. If you can write some data to the TDQ (I'm not sure how - need to find out) using REXX/COBOL, then you can setup a Queue manager to trigger a transaction in CICS.

Thanks,
Phantom

Ramkumar,

CICS MVS/ESA EXCI interface to REXX provides a full function External CICS Interface program which allows a REXX EXEC to invoke a CICS program. A REXX variable may represent the COMMAREA for input to the CICS program and any modifications to the COMMAREA made by the CICS program are reflected in the REXX variable upon returning from CICS. Return codes are passed back to the REXX EXEC in specialized REXX variables.

Check this link which explains in detail about REXX for CICS

Hope this helps...

Cheers

Kolusu

Wow, Thanks a lot kolusu,

I never made an attempt to take a copy of/read through the REXX-CICS manual. The main problem I face with CICS & DB2 is authorization. If my project doesn't require CICS/DB2 then I don't even have the authorization to try out anything.....I'm really missing lots of things.

Thanks.

FYI, as an alternative, we use OSPI (Open Systems Procedural Interface) from BMC to logon, start, and monitor CICS transactions from the REXX-based automation of BMC's MainView AutoOPERATOR.

Hi,

Thanks a lot everybody....
The REXX/CICS manual is really helpful.

Thanks & Regards,
