Introduction
When a Nirvana cluster needs to be deleted, all cluster
channels and queues that exist in all cluster member
realms will also be deleted. Removal of a cluster is
a simple operation that can be achieved using the Enterprise
Manager. This section will describe the process of removing
a cluster.
In order to remove a Nirvana Realm cluster, you must
first of all select the 'Clusters' node from the Enterprise
Manager. Right-clicking on this node will present a
pop up menu, as shown in the image below.

Selecting the menu option 'Delete Cluster' will prompt
you with a dialog that asks you to select a cluster
node from a list. This list will contain all known clusters
within the realms you have connected to. This dialog
is shown in the image below.
Clicking on the 'OK' button once you have selected
the cluster you wish to delete will prompt you to answer
a question. This question gives you 2 choices with regard
to the cluster channels and queues that may exist within
the cluster. These are:
- Delete all cluster wide channels and queues from
each cluster realm
- Convert all cluster wide channels and queues to
local within each realm
Choosing to delete all cluster channels and queues
will not remove any locally created channels, only those
created for the cluster.
Choosing to convert each one to local, will keep any
data that may be contained with the channels or queues.
This dialog is shown in the image below. Choosing 'Yes'
will remove the cluster objects, 'No' will make them
all local, 'Cancel' will take no action at all.
