Locking a Client Queue
Before you can modify the contents of a queue, you must lock the queue. (If you just want to browse the contents of a queue, you do not need to lock it.) Keep the following points in mind when working with locked client queues:
*You can have multiple queues locked at one time.
*You must have administrative privileges to lock a queue.
*Other users, including the queue owner, cannot clear the contents of a queue or delete the queue while it is locked.
*Broker continues to place documents to which the client subscribes in a locked queue.
*A client cannot retrieve documents from a locked queue.
*While the queue is locked, Broker processes document acknowledgements for documents that the client retrieved before you locked the queue.
*When you lock a queue, My webMethods creates a volatile client to own the queue lock. This client belongs to the admin client group and has an application name that matches the following format: Messaging Management Queue Browser on ClientID (username) Click the client ID in the Client List to view details about this client.
*The queue remains locked until you specifically unlock the queue, your My webMethods session ends, or the volatile client created to hold the queue lock is destroyed.
