DFS3495W OTMA HAS BEEN WAITING FOR AN ACK FROM TMEMBER/TPIPE xxxx/yyyy FOR OVER zzzz SECONDS.

Explanation

OTMA detected that member xxxx with transaction pipe (tpipe) yyyy has been waiting for an acknowledgment for more thanzzzz seconds. Because the OTMA CM0 ACK timeout function has been turned off, OTMA does not take the timeout action to reroute the output message.

System action

Processing continues. The tpipe remains in a hang status. All of the queued output messages on the tpipe are not delivered until the ACK or NAK is received.

Operator response

Identify the cause of the missing ACK or NAK for this timeout condition. The problem might be an application program, or a failure in the network component. You can restart the tpipe manually with a /STOP TMEMBER tpipe and then a /START TMEMBER tpipe command.

Programmer response

Make sure that your program issues an ACK or NAK to IMS for the received CM0 output message. Also, it is possible that there is a network failure so that the ACK or NAK cannot arrive at IMS OTMA.

Problem determination

Examine the network trace to identify which component in the network did not forward the ACK or NAK to IMS.
