DFS4199W A new mode of Resume TPIPE request needs to be submitted for IMS synchronous callout messages
Explanation
There were IMS synchronous callout messages in the OTMA TPIPE queue waiting to be retrieved. However, the Resume TPIPE request received was only targeted for asynchronous output messages.
System action
Processing continues for only asynchronous callout messages.
Operator response
Issue a new Resume TPIPE request with the correct processing mode for synchronous callout messages that are waiting to be processed.
The byte-3 of OTMA state data prefix can be used to set the Resume TPIPE processing mode. When the flag X'80' is set in the byte, it means the Resume TPIPE can be issued to retrieve only the synchronous callout messages.
When the flag X'40' is set in the byte, it means the Resume TPIPE can be issued to retrieve both synchronous callout messages and asynchronous messages. The synchronous callout messages are processed and delivered before the asynchronous messages.
