Clear WebSphere MQ Publish/Sub (CLRMQMBRK)

The Clear WMQ broker (CLRMQMBRK) is used to clear the broker's memory of a neighboring broker. The broker cancels all subscriptions from the target broker. The broker must be stopped when this command is issued. The command is synchronous, and when it has completed the broker can be restarted normally. No messages are read from any of the input queues. After restart, the broker detects any messages on its input queues that came from this broker, and processes them according to their report options.
