Stops processing of messages enqueued for the specified channel. This command prevents you from having to stop the Job Controller and recompiling the configuration. The channel does not process messages until a start command is issued for that channel. This state persists across restarts of the Job Controller, the Messaging Server, and the host computer itself. This command takes effect whether the Job Controller is running or not.
The channel parameter specifies the channel to stop.
The command imsimta qm start/stop channel may fail if run simultaneously for many channels at the same time. The tool might have trouble updating the hold_list and could report: "QM-E-NOTSTOPPED, unable to stop the channel; cannot update the hold list." imsimta qm start/stop channel should only be used sequentially with a few seconds interval between each run. If you only want the channel to run between certain hours, use the following options in the channel definition section in the job controller configuration file: urgent_delivery=08:00-20:00
