Title: RE: MQ Triggering in CICS

Is there a way to dynamically set the userid? As long as we are creating a SIL in CICS, is there a way for the SIL to specify the userid when issuing the EXEC CICS START ?   Peter Heggie -----Original Message----- From: MQSeries List [mailto:[EMAIL PROTECTED] On Behalf Of Adiraju, Rao Sent: Tuesday, March 02, 2004 3:11 PM To: [EMAIL PROTECTED] Subject: Re: MQ Triggering in CICS   Few more points to add: (I was quick in pressing the send button):    As a design principle the CICS program always should issue a EXEC CICS RETRIEVE  - 1) as Joe mentioned, to determine whether this transaction has triggered by CKTI (or one of the equivalents) and secondly to retrieve the trigger message. Trigger message gives you the information about which queue has resulted the trigger, trigger data (that is defined on the base queue), Process name, application data and user data that was put in the PROCESS definitions etc..  Usually the program should determine the queue that it is supposed to read from this trigger message (which is more reliable) rather than hard-coding / soft-coding in the program.    Also, most of the times CKTI starts with a default user-id (or CICS userid) and hence your transaction also runs under the same user-id. So watch out for your security rules.      Cheers   Rao    From: Adiraju, Rao Sent: 3 March 2004 8:59 AM To: 'MQSeries List' Subject: RE: MQ Triggering in CICS John   Additional point to what Joe mentioned - yes, the default you look for is "CKTI" in Rtransid field. But check with your CICS guys as well - because it is possible one CICS region to have multiple initiators and/or different transaction codes (for various reasons).   If that's  case you need to check for those codes as well (or instead).   Cheers   Rao Adiraju WebSphere MQ Specialist The National Bank of NZ Ltd.

EXEC CICS RETRIEVE                          SET (ADDRESS OF MQTM)         LENGTH (LENGTH  OF MQTM)       RTRANSID (VARIABLE-RTRANSID)                RESP (VARIABLE-EIBRESP)        END-EXEC. Make sure you include copybook CMQTML in your linkage section. And define the variables in working storage.
