Creating a queue manager cluster

IBM MQ Explorer treats queue manager clusters as objects so that we can create and administer them like other MQ objects.

About this task

All the queue manager clusters that are known to IBM MQ Explorer are displayed in the Queue Manager Clusters folder.

Before we can create a new queue manager cluster:

• Create two queue managers that will have the full repositories for the cluster.
• Each full repository queue manager in the cluster must have a running listener.
• You must know the connection details of each full repository queue manager in the cluster because the you are asked to enter these details in the wizard.

Note: We cannot use the Create Cluster wizard if the full repository queue managers already belong to another cluster. If you want to use queue managers that already belong to another cluster, you must configure the cluster using the MQSC commands.

To create a new cluster, complete the following steps.

Procedure

1. In the Navigator view, right-click the Queue Manager Clusters folder, then click New... The Create Cluster wizard opens.
2. Work through the pages in the wizard to enter the following information about the new cluster:
   1. Page 1: The name of the new cluster. This name must be unique in your organization.
   2. Page 2: The name of a queue manager that will have a full repository of information about the cluster. The queue manager must already exist; click Add queue manager to MQ Explorer if the queue manager is not already known to IBM MQ Explorer.
   3. Page 3: The name of a second queue manager that will have a full repository of information about the cluster. The queue manager must already exist; click Add queue manager to MQ Explorer if the queue manager is not already known to IBM MQ Explorer.
   4. Page 4: The connection name of the first full repository queue manager. The format of the connection name depends on the transport protocol that the queue manager uses. For example, if the queue manager uses TCP/IP, we can use the format computer_name(port_number) where computer_name is the name of the computer that hosts the queue manager, and port_number is the port number on which the queue manager listens for connections.
3. Click Finish to create the cluster.

Results

The new cluster is displayed in the Queue Manager Clusters folder. The cluster's full repositories are shown in its Full Repositories folder.
