Namelists
A namelist is an IBM MQ object that contains a list of cluster names, queue names or authentication information object names. In a cluster, it can be used to identify a list of clusters for which the queue manager holds the repositories.
A namelist is an IBM MQ object that contains a list of other IBM MQ objects. Typically, namelists are used by applications such as trigger monitors, where they are used to identify a group of queues. The advantage of using a namelist is that it is maintained independently of applications; it can be updated without stopping any of the applications that use it. Also, if one application fails, the namelist is not affected and other applications can continue using it.
Namelists are also used with queue manager clusters to maintain a list of clusters referred to by more than one IBM MQ object.
We can define and modify namelists by using MQSC commands. Alternatively, on z/OS, we can use the IBM MQ for z/OS operations and control panels
Programs can use the MQI to find out which queues are included in these namelists. The organization of the namelists is the responsibility of the application designer and system administrator.
