Timeout specifications for IMS-to-IMS connections

For IMS application programs that send transactions to a remote IMS system by way of OTMA, you can specify timeout values on the RMTIMSCON and DATASTORE configuration statements.

The IDLETO keyword in the RMTIMSCON configuration statement controls how long IMS Connect keeps open a persistent socket connection if no additional messages are received from IMS for the connection.

The ACKTO keyword on the DATASTORE configuration statement controls how long OTMA waits for an acknowledgement from IMS Connect before rerouting the output to the timeout tpipe queue and issuing an error message.

The timeout interval for acknowledgements can also be set in OTMA by either the TIMEOUT keyword of the /START TMEMBER command or the T/O parameter in the OTMA client descriptor in the DFSYDTx PROCLIB member.
