Hi,
I'm trying to trigger a CICS transaction when a message comes into my MQ Local Queue in Mainframe. The following is the process that I have followed. Please let me know if there is anything wrong in this..
Created a Local Queue
Created an Initiation Queue
Created a Process
Now in the Process in the Application ID I have given the CICS Transaction Name. Is this correct ???
Then I went to CKTI and started the Initiation Queue.
Now When I put a message in my Local Queue, my CICS pgm related to that Transaction should start. But its not happening in that way.
Please clarify what I have missed. I did check the Local Queue, Initiation Queue and Process Definitions and they seem to be ok.
Thanks,
Deepesh |

Pedantically, you can't start a queue. You start CKTI (trigger monitor) and point it at the initiation queue you're using.
Aside from this possibly irrelevant point, are all the other conditions for whatever trigger type you've specified (which you don't mention) set up correctly? For instance, are you trying to start a trigger first with messages already in the queue?

Vitor,
The Trigger Type is First (F). Yes I'm already having some messages in my Local Queue.
What should be the value in the Application ID in the Process Definition. In the IBM Manual, they have given an example of a program in Unix Env for which they are specifiy the exe path in Appl ID. In CICS what should be the value for Application ID.
Thanks,
Deepesh |

If you refer back to the IBM manual, you'll notice it states the a trigger type first message is raised when the queue depth goes from 0 -> 1 (i.e. the first message is received) among other conditions.
Hence if you have messages on the queue, this condition will never be met and the trigger message never sent.

I read my local queue till all the messages are read and the Current queue depth = 0. Then I started the CKTI (trigger monitor) and pointed it at the initiation queue that I'm using.
Now when i tried a message to the local queue, the Current queue depth becomes 1 but it does not trigger the CICS txn that i have given in Application id of my process definition.
Any thoughts ?

Is this maybe a security related problem? Have you checked the logs (MQ, CICS, and system)?

Are you sure that your transaction is not being started and then failing quietly?
Does it issue any 'Hello World' messages to show that is has started up?
Has it been coded to expect an MQTM on input?
Are there any console messages from the trigger monitor?
Are there any messages on the Dead Letter Queue?
If you are able to run CKQC what does the CKTI display show for the number of APIs issued by the trigger monitor?
If you temporarily change your process to specify transaction CKBR does the CICS bridge transaction start?

Bob,
Here r the answers

Yes the transaction did start and from the CICS Admin i got the abend ABM3. The description of the error is as below
=========================================
ERZ062007E Abnormal termination ABM3. Basic Mapping Support (BMS) operation requested by a non-terminal transaction.
Explanation: A non-terminal transaction, such as an Automatic Transaction Initiation (ATI) transaction with no terminal specification, requested a BMS operation.
System Action: CICS terminates the transaction with abend code ABM3.
User Response: Either remove the BMS commands from the transaction, or initiate the transaction from a terminal.
=========================================

NO

NO
I think the program is failing at the EXEC CICS SEND Command. Is it that i have to accept MQTM as input always ? If you have any sample program which accepts MQTM as input, plz send me the link.
Thanks,

Then it sounds like the trigger process is working fine, but you're trying to send a BMS map to a non-terminal context. In any event, it's a application issue and you need to resolve it outside the strict MQ arena.

All triggered applications receive a triggered header; how else would they know how, why or where they'd been triggered from? Samples are provided in all the usual places and the header format is described in the APR. The use of the fields is described in the APG, not far from where you read about the triggering conditions.

You might want to take a look at the MA1K SupportPac. Program J7200506 has some example code which may be helpful. |
