Hi,
i had a production failure. on saturday the cics on z/OS was shut down and restarted just on monday morning. meanwhile we were receiving messages in mqs from where i'm triggering through an initiaton queue and system cics bridge a cics transaction. as far as i can see my prepared messages are available on the different message queues. But i'm not abel to find the triggering cics messages.
Shouldn't I find them on the DeadLetterQueue ?
cheers and a nice weekend

No. Because if I remember correctly, the Trigger Initiation program also runs in CICS. So, if CICS was down, no Initiation Program running. So, no trigger message generated.
See the Application Programmers Guide for a full list of conditions that must be satisfied before a trigger message is generated.
Cheers,

make sure your triggering interval (qmgr property) is low enough (300,000 => 5 min) before starting production.
Enjoy  |

What was the CICS doing for two days? CKTI is an always running tran that will do it's EXEC CICS START immediately. If the trans are not able to start you've lost your trigger message.

What presumably happened is just that you have (I suppose) trigger type FIRST. This means your transaction will be started only if there is 0-to-1 change in queue depth. Now, you had had the queue(s) filled with messages and that's why no trigger message was generated.
