Channel control function

The channel control function provides facilities for you to define, monitor, and control channels.

Commands are issued through panels, programs, or from a command line to the channel control function. The panel interface also displays channel status and channel definition data. You can use Programmable Command Formats or those IBM® MQ commands (MQSC) and control commands that are detailed in Monitoring and controlling channels on Windows, UNIX and Linux platforms.

The commands fall into the following groups:
  • Channel administration
  • Channel control
  • Channel status monitoring
Channel administration commands deal with the definitions of the channels. They enable you to:
  • Create a channel definition
  • Copy a channel definition
  • Alter a channel definition
  • Delete a channel definition
Channel control commands manage the operation of the channels. They enable you to:
  • Start a channel
  • Stop a channel
  • Re-synchronize with partner (in some implementations)
  • Reset message sequence numbers
  • Resolve an in-doubt batch of messages
  • Ping; send a test communication across the channel
Channel monitoring displays the state of channels, for example:
  • Current channel settings
  • Whether the channel is active or inactive
  • Whether the channel terminated in a synchronized state
