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.
To lock a client queue
1. In My webMethods: Messaging > Broker Server s > Clients.
2. In the Client List, click the client ID of the client whose queue you want to lock. If the client does not appear in the list, use the Search tab to locate it.
3. On the Client Details page, click the Configuration tab.
4. Click Lock Queue.
