DFS0809E IMS region region-id (in IMS back-end aaaaaaaa) has timed out for OTMA client yyyyyyyy tpipe xxxxxxxx for nn seconds.

Explanation

OTMA detected a timeout for a transaction running in a dependent region for a CM1 message. The information in the message is as follows:
aaaaaaaa
IMS name
yyyyyyyy
OTMA client name
xxxxxxxx
The transaction pipe name
nn
Time in seconds that the region has been in a wait state

System action

For MPP regions, IMS terminates the transaction abnormally and issues an abend 0119.

For IFP regions, the action depends on the shared queue environment.
  • Without shared queues, or with shared queues but when processing a local transaction (originating on processing IMS), no abend is issued. IMS backs out the updates and sends a deallocate abnormal flow to the end-client.
  • For IFP regions, operating in a shared queue environment and processing as a back-end (message origin is not the processing IMS), an abend 0119 is issued.

Programmer response

Check the OTMA client application to determine why the required ACK or NAK response is not sent to IMS OTMA.
