Specifying the purge function for undeliverable commit-then-send output

If you are using either the HWSSMPL0 or the HWSSMPL1 IMS Connect user message exit, you can enable the purge function for undeliverable commit-then-send output by specifying the IRM_F3_PURGE flag (X'04') in the IRM_F3 field on certain types of input messages.

You can specify the purge function on the following input messages from a client application:

  • A SEND of a commit-then-send (CM0) transaction.
  • A SEND of a send-then-commit (CM1) transaction. A purge request on CM1 input applies only to any CM0 output that the CM1 input generates.
  • A SEND of a NAK response to CM0 output.
Restriction: You cannot specify the purge function and the reroute function at the same time. If both functions are specified, the output messages are neither purged nor rerouted from the original output queue and OTMA issues message DFS2407W.
