The dmpmqmsg command is used to perform a number of tasks, including moving messages from queue "a" to queue "b". In this example, the messages on QUEUE01 are moved to QUEUE02.

dmpmqmsg -m MANAGER01 -I QUEUE01 -o QUEUE02

The following will be displayed after issuing the command. In this example, 4 messages were moved from QUEUE01 to QUEUE02.
