Work with queue manager channels

We can use the IBM MQ Console work with queue manager channels: we can add and delete queue manager channels, start and stop channels, reset and resolve channels, and ping channels. We can also view and set the properties of a queue manager channel, and manage authority records for the channel.

About this task

A queue manager channel is a logical communication link for transmitting messages between queue managers across a network. The queue manager channel view includes a panel that shows a quick view of how many channels are running, how many retrying, and how many stopped.

We cannot view or edit authority records for a channel on z/OS .

Procedure

• To add a queue manager channel:
  1. In the Communication tab, ensure the queue manager channels view is displayed and click the create button .
  2. Select the type of queue manager channel that we want to create and click the next button .
  3. Provide the required information for the channel we are creating. By default the minimum recommended properties are displayed for you to provide values for. We can view all of the available properties by selecting Show all available options.
  4. Click Create. The new channel is created with the inactive status.

• To reset a queue manager channel:
