@MOMINIT

Identifies the type of Message Oriented Middleware (MOM) message manager, and initializes its environment (map and control structures) to enable subsequent @MOM calls. (C)

Invocation

CALL @MOMINIT(buflen, mom_type)

 

buflen	The size of the largest message to be processed.
mon_type	The type of queue manager you want to use in the current session. If mom_type is null, an appropriate queue manager is selected. The only queue manager currently available is MQSERIES.

Usage Notes

•	If you prefer to allocate your own record storage map table, set buflen to 0 and update @MQSMAP.BUFFER_ADDRESS and @MQSMAP.BUFFER_LENGTH with the corresponding information after the @MOMINIT call.

•	WebSphere MQ on z/OS is TCB-specific. Therefore, @MOMINIT sets TCB affinity for the transaction and an interpreter TCB is held for the duration of the transaction. In a multi-user Execution Environment, consider increasing the value of your TASKEXECNUM Execution Environment parameter.

Exceptions

 

MOM_INV_@MOMMAP	The address received does not point to a valid control block.
MOM_INV_COMMAND	The command received is invalid.
MOM_INV_MOMMSG	The control message received is invalid.
MOM_NO_MQSSTUB	The stub program for WebSphere MQ has not been link-edited into the HRNDRSES load module.
MOM_SMALL_MAPSTG	The control block passed is too small.

Example

Refer to the example in the section on the Service Gateway for WMQ in TIBCO Object Service Broker for z/OS External Environments or TIBCO Object Service Broker for Open Systems External Environments.
