Main Success Scenario
Trigger: The direct actor triggers this use case based on the actions of the primary actor.
The steps involved in the use case for creation or modification of a private queue are:
The application sends a request to the queue manager to create a private queue on that queue manager or to modify an existing private queue hosted by the queue manager.
The queue manager creates or modifies the queue and sends a response back to the application.
The steps involved in public queue creation or modification are:
The application sends a request to a queue manager to create a public queue on any queue manager in the directory or to modify an existing public queue hosted by any queue manager in the directory.
The queue manager sends a message to the Directory Service to make the necessary changes in the directory. On receipt of this message, the Directory Service creates the public queue in the directory.
The queue manager sends a notification message to the queue manager that is hosting the queue to notify it of the changes. On receipt of such a notification message, the hosting queue manager synchronizes the changes identified in the notification message.
The queue manager sends a response back to the application.
Postcondition
