Resolve MQ Channel (RSVMQMCHL)

Where allowed to run: All environments (*ALL)
Threadsafe: Yes

The Resolve MQ Channel (RSVMQMCHL) command requests a channel to commit or backout in-doubt messages.

This command is used when the other end of a link fails during the confirmation period, and for some reason it is not possible to reestablish the connection.

In this situation, the sending end remains in an in-doubt state, about whether the messages were received. Any outstanding units of work need to be resolved with either backout or commit.

*BCK restores messages to the transmission queue and *CMT discards them.

Use this command for sender (*SDR) and server (*SVR) channels only.
