RESET CHANNEL

For an explanation of the symbols in the z/OS column, see Using commands in z/OS.

Use RESET CHANNEL to reset the message sequence number for a WebSphere MQ channel with, optionally, a specified sequence number to be used the next time that the channel is started.

  1. On z/OS, the command server and channel initiator must be running.

  2. This command can be issued to a channel of any type except SVRCONN and CLNTCONN channels, (including those that have been defined automatically). However, if it is issued to a sender or server channel, then in addition to resetting the value at the end at which the command is issued, the value at the other (receiver or requester) end is also reset to the same value the next time this channel is initiated (and resynchronized if necessary). Issuing this command on a cluster-sender channel may reset the message sequence number at either end of the channel. However, this is not significant because the sequence numbers are not checked on clustering channels.

  3. If the command is issued to a receiver, requester, or cluster-receiver channel, the value at the other end is not reset as well; this must be done separately if necessary.

  4. Where there is both a locally defined channel and an auto-defined cluster-sender channel of the same name, the command applies to the locally defined channel. If there is no locally defined channel but more than one auto-defined cluster-sender channel, the command applies to the channel that was last added to the local queue manager’s repository.
