Query regarding MQCB

Postby pranav283 » Wed May 02, 2018 12:11 am

Hi,

We are deploying the CICS Asynchronous Message Consumption in our site.
To achieve this, a typical registration CICS module registers MVRG0001 (transid MVRG) a callback CICS module MVMC0001 (using MQCB call) that is responsible for consuming the message from the queue/topic.

The problem is while registering the consumer module MVMC0001 using MQCB, I am getting an error - RC 2495 which is MQRC_MODULE_NOT_FOUND.
This could be because we are not defining the PPT entry for the consumer module. Instead, we assumed that it will loaded to CICS whenever it is invoked by the queue manager whenever a message arrives on the queue.
However, the consumer module got register successfully when we newcopied it in the first run of MVRG and it started consuming messages.

So, is there is a way to check whether MVMC0001 has been registered in the MQ setup? If yes, then I will skip this step itself as it will be redundant.
