Use the MQSC command DELETE CHANNEL to delete a channel definition.

Usage notes
- Successful completion of the command does not mean that the action completed. To check for true completion, see the DELETE CHANNEL step in Checking that async commands for distributed networks have finished.
- On z/OS systems, the command fails if the channel initiator and command server have not been started, or the channel status is RUNNING, except client-connection channels, which can be deleted without the channel initiator or command server running.
- On z/OS systems, you can only delete cluster-sender channels that have been created manually.
Parameter descriptions
- (channel-name)
- The name of the channel definition to be deleted. This is required. The name must be that of an existing channel.
- CHLTABLE
- Specifies the channel definition table that contains the channel to be deleted. This is optional.
- QMGRTBL
- The channel table is that associated with the target queue manager. This table does not contain any channels of type CLNTCONN. This is the default.
- CLNTTBL
- The channel table for CLNTCONN channels. On z/OS, this is associated with the target queue manager, but separate from the main channel table. On all other platforms, this channel table is normally associated with a queue manager, but can be a system-wide, queue manager independent channel table if you set up a number of environment variables. For more information about setting up environment variables, see Using IBM MQ environment variables.
- CMDSCOPE
- This parameter applies to z/OS only and specifies
how the command is executed when the queue manager is a member of a queue-sharing group. CMDSCOPE must be blank, or the local queue manager, if QSGDISP is set to GROUP.
- ' '
- The command is executed on the queue manager on which it was entered. This is the default value.
- qmgr-name
- The command is executed on the queue manager you specify, providing the queue manager is active
within the queue-sharing group.
You can specify a queue manager name, other than the queue manager on which the command was entered, only if you are using a queue-sharing group environment and if the command server is enabled.
- *
- The command is executed on the local queue manager and is also passed to every active queue manager in the queue-sharing group. The effect of this is the same as entering the command on every queue manager in the queue-sharing group.
- QSGDISP
-
This parameter applies to z/OS only.
Specifies the disposition of the object to which you are applying the command (that is, where it is defined and how it behaves).
- COPY
- The object definition resides on the page set of the queue manager that executes the command. The object was defined using a command that had the parameters QSGDISP(COPY). Any object residing in the shared repository, or any object defined using a command that had the parameters QSGDISP(QMGR), is not affected by this command.
- GROUP
- The object definition resides in the shared repository. The object was defined using a command
that had the parameters QSGDISP(GROUP). Any object residing on the page set of the queue manager
that executes the command (except a local copy of the object) is not affected by this command. If the command is successful, the following command is generated and sent to all active queue managers in the queue-sharing group to delete local copies on page set zero:
The deletion of the group object takes effect even if the generated command with QSGDISP(COPY) fails.DELETE CHANNEL(channel-name) QSGDISP(COPY)
- QMGR
- The object definition resides on the page set of the queue manager that executes the command.
The object was defined using a command that had the parameters QSGDISP(QMGR). Any object residing in
the shared repository, or any local copy of such an object, is not affected by this command.
This is the default value.
