6.3.1 OTMA Client Gateway

The request message presented to the server transaction contains the name of the transaction pipe (tpipe) in the LTERM field of the I/O PCB. If the security feature is in use, the USERID and GROUPID fields of I/O PCB also contain relevant data.

If a response is required, the response message is inserted into the IMS message queue and routed back to the gateway by OTMA. The response message is inserted either as a single segment, or as multiple segments. The TMA TCP for IMS gateway can handle either format.
