What are the different types of channels in MQ?
IBM® WebSphere® MQ uses two different types of channels:
- A message channel, which is a unidirectional communications link between two queue managers.
- An MQI channel, which is bidirectional and connects an application (MQI client) to a queue manager on a server machine.
How do I check my MQ channels?
You can display channel status by using MQSC commands, or by using the operations and control panels. To display the status of a channel or a set of channels using the MQSC commands, use DISPLAY CHSTATUS. Note: Displaying channel status information can take some time if you have lots of channels.
How do I check my queue Manager properties?
Select the name of the queue that the queue manager uses as the dead-letter queue. Type the number of milliseconds, from 0 to 999999999, that the queue manager must wait between triggering messages for a queue. This attribute is used only when the Trigger type attribute in the Queue properties is set to First .
What is MQ sender channel?
A sender channel is a message channel that the queue manager uses to send messages to other queue managers. To send messages using a sender channel, you must also create, on the other queue manager, a receiver channel with the same name as the sender channel.
What is MQ channel?
Introduction. The MQ Channel plug-in is part of a suite of plug-ins designed to monitor an IBM WebSphere MQ server. MQ is a middleware product which allows independent client programs to communicate by passing messages to each other via a message queue.
What is MQ channel name?
MQI channels A Message Queue Interface (MQI) channel connects an IBM MQ MQI client to a queue manager on a server machine, and is established when you issue an MQCONN or MQCONNX call from an IBM MQ MQI client application.
How do I check my channel initiator status?
You can display information about the channel initiator using MQSC commands or using the operations and control panels. To display information about the channel initiator using the MQSC commands, use DISPLAY CHINIT. You are presented with another panel. Select function type 1 on this panel.
What is remote and local queue in MQ?
When an Adapter connects to a remote queue manager and accesses one of its queues, then that queue, is also a local queue. In WebSphere MQ terms, a remote queue is a queue that is managed by a queue manager other than the one to which the application (in this case, the Adapter) is connected.
How do you create an MQ channel?

- In the Navigator view, expand the queue manager QM_APPLE that you created earlier.
- Right-click the Channels folder, then click New > Receiver Channel. The New Receiver Channel wizard opens.
- In the Name field, type QM_ORANGE.QM_APPLE.
- Click Finish.
How do you create a channel in MQ?
What is server connection channel in MQ?
A server connection channel is a bidirectional MQI channel that is used to connect an IBM MQ client to an IBM MQ server. The server connection channel is the server end of the channel. A client connection channel is a bidirectional MQI channel that is used to connect an IBM MQ client to an IBM MQ server.
What is namelist in MQ?
A namelist is an IBM® MQ object that contains a list of cluster names, queue names or authentication information object names. In a cluster, it can be used to identify a list of clusters for which the queue manager holds the repositories. A namelist is an IBM MQ object that contains a list of other IBM MQ objects.
How do I list queues in IBM MQ?
Use the MQSC command DISPLAY PROCESS to display the attributes of one or more WebSphere MQ processes. Use the MQSC command DISPLAY PUBSUB to display publish/subscribe status information for a queue manager. Use the MQSC command DISPLAY QMGR to display the queue manager parameters for this queue manager.
