Re: MQ Trigger Monitor - Load Balancing?
Hi, In a few words, we use the following configuration : We have special CICS region for MQ : called MOR for MQ-owning region. Trigger monitors are running in the MOR. The triggered transaction is defined as dynamic in MOR and as static in AOR. In this configuration, triggered transaction are routed dynamically to the AOR. So, the best practice is compute by WLM (CICS choose the region, MQ stay independant). For high availability, we have 2 MOR reading the same shared initiation queue. Hope this help you.

Dear MQA, We are studying on sharing of a single queue manager by multiple CICS regions. If we use CICS trigger monitor (i.e. CTKI), can the trigger monitor distribute workload equally among the two CICS regions? If otherwise, which component (MQ, CICS or else) can govern the workload distribution. Besides, if one of the CICS regions fails, can all the incoming messages be distributed to the remaining one for processing. TIA.

Re: MQ Trigger Monitor - Load Balancing?
Hi, For the first part, no, MQ can't distribute the workload, but CICSPLEX can. The trigger message gets picked up by whichever CKTI instance MQGETs it first, which in turn initiates a CICS transaction. CICSPLEX will then schedule the CICS transaction to a CICS system, according to its configuration. The second: not as such, but to an equivalent outcome - If one CICS system is dead, only the other system's CKTI is active, so it gets the trigger message. All the above assume that both CICS systems' CKTI's monitor the same MQ initiation queue, and that the MQ and CICS systems are hosted by the same Sysplex member. To get one stage smarter, if your systems are Sysplex'ed, you could consider sharing the initiation and application queue. In this case, a message could be serviced by any CICS system in the plex. However, only consider this after thorough analysis of volumes, message length etc., so as to not break your coupling facility.
