IMS termination and IMS-to-IMS TCP/IP messages

If a tpipe is in a WAIT_R state when IMS terminates normally or abnormally, OTMA reroutes the messages on the tpipe to the default timeout queue, DFS$$TOQ, during restart processing.

The WAIT_R status of a tpipe indicates that OTMA is waiting for an acknowledgment of receipt for a message sent to a remote IMS system.

You can clear the WAIT_R status of a tpipe by issuing the /STOP TMEMBER TPIPE command.

You can use the /DISPLAY TMEMBER command to determine which OTMA tpipes have a WAIT_R status.
