Hey!
I would like to run, on different CICS, CKTI that will both listen to the same initiationQ.
My motivation to do this:I have a trigger application that i like to be run simultaniously from 2 cics at the same time (for performance reasons, or failre of one cics).
Thank you  |

Are both CICS systems attached to the same queue manager?

hi,
should be possible, but what Vitor asked must be true, and only if CKTI does not use exclusive open (dont know that, but you can check that easily by looking at the queue status).

Available messages get attributed on a first come, first serve basis. I doubt you will have any control over that

Yes - have separate initiation queues and control workload (you mentioned performance) via MQ clustering.
I discount this whole "failure of one CICS" reason of yours. CICS regions do not fail. If they do, the standard response is to take any of the sys progs who have not killed themselves to avoid the shame out into the car park & do unspeakable things to them. Like recite "I love Windows" for 10 minutes.
Or that cruel and unusual? 
Seriously, what CICS failure scenarios to do envisage?
Also, have you investigated Mr Butcher's point about CKTI using exclusive access (or not)? If it does, and I believe it does, that scuppers your plan good and proper. I would be interested to know if I'm right (because it's only a belief) and I don't have a mainframe to hand.

Hi Vitor, I am not the thread starter.
I was curious about how hilla's statement "i like to be run simultaniously from 2 cics at the same time" can become true. That's why I asked my questions. |

Hey all,
Thanks for the advices.
The two cics's are connected to the same QMGR.
About the exclusive access - the default option is exclusive. I'll try to change that and see what's going on.
Do you know about a way to start ckti (manualy and not by plt) with a system user? (If i start it via ckbr, it takes my user and not the cics's user).
10X!

check the system administraiton guide for the possibilities to start ckti transaction.
i would write a small program / transaction that could either be executed via plt on cics start, or you can use start trransid user() to start the transaction that is starting ckti.
maybe there is a direct way using ceci but you may want to try yourself.
