Setting a transaction expiration time with IMS Connect

You can instruct IMS Connect to set an expiration time for transactions submitted to IMS that matches the timeout value of the socket connection on which the transaction is submitted.

For IMS Connect to set a transaction expiration time, a timeout value for the socket connection must first be specified in either the TIMEOUT parameter of the TCPIP configuration statement or the IRM_TIMER field in the fixed section of the IRM prefix.

You can instruct IMS connect to set a transaction expiration time for a transaction by using one of the following methods:

Specify X'01' (IRM_F1_TRANEXP) in the IRM_F1 field of the user section in the IRM prefix of the input message.
When IRM_F1 is set to X'01', the user message exit sets the OMHDRIST field to X'01' (OMHDRXP1) in the state data section of the OTMA header.
Modify any of the following user message exit routines to set the IRM_F1 field to X'01' (IRM_F1_TRANEXP).
- HWSSMPL0
- HWSSMPL1
- HWSSOAP1
When IRM_F1 is set to X'01', the user message exit sets the OMHDRIST field to X'01' (OMHDRXP1) in the state data section of the OTMA header.
