A get cursor operation is provided within the queue to point to a current starting place for a getting application to start searching for a message to retrieve. A first lock is provided for putting operations, in response to there being more than one putting application, to ensure only one application is putting to the queue at a time. A second lock is provided for getting operations, in response to there being more than one getting application, to ensure that only one application is getting from the queue at a time. Putting applications and getting applications are synchronized to check and update the get cursor operation. |
