PURGE CHANNEL

Use the MQSC command PURGE CHANNEL to stop and purge a telemetry channel. Purging a telemetry channel disconnects all the MQTT clients connected to it, cleans up the state of the MQTT clients, and stops the telemetry channel. Cleaning the state of a client deletes all the pending publications and removes all the subscriptions from the client.

(channel name)
The name of the telemetry channel to be stopped and purged. This parameter is required.
CHLTYPE(MQTT)
Channel type. This parameter is required. It must follow immediately after the (channel-name) parameter on all platforms except z/OS®, and the value must currently be MQTT.
CLIENTID(string)
Client identifier. The client identifier is a 23 byte string that identifies a IBM® WebSphere® MQ Telemetry Transport client.
