Join Default Cluster

To make the default configuration cluster, one of the queue managers in the cluster must hold the cluster repository, and all the others must point to it (this is slightly different to clusters in general. For more information about clusters and repositories, see the Quick Tour.

Table 1.
If.. Then..
This is the first installation of WebSphere MQ Version 6.0 on a computer in this cluster.. Choose Yes to make this one a repository.
Note: If this computer uses DHCP (dynamic allocation of IP address) you are normally recommended not to put a repository on it (because if its IP address changes, other queue managers, even on this computer, will no longer be able to find it). However, if this will be the only queue manager in the cluster then it is all right to make it the repository
WebSphere MQ has already been installed on another computer and a queue manager on that computer has been defined as a repository for the cluster.. Choose No, and on the next panel (Remote Repository) specify the name of the computer holding the repository queue manager.
