About this task
If the hostname or IP address for a cluster node gets updated, you must reconnect the
nodes in the cluster as described in the following steps. Note that if you are not using a
remote join or zone, node in the following steps refers to a node that is part
of the cluster. If you are using a remote join or zone, node refers to a node
that is part of the remote join or zone.
Procedure
-
In a text editor, create a file with name remote_realms_bootstrap.conf and save the
file in the new_Software
AG_directory/UniversalMessaging/server/instance_name/bin
directory.
-
In the remote_realms_bootstrap.conf file, add a cross-host mapping property for each
node within the cluster in the following format:
instance_name.address=new_host_name_or_IP_address
For example, umserver1.address=myUM1.com or
umserver2.address=192.168.0.1.
-
Copy the file to the new_Software
AG_directory/UniversalMessaging/server/instance_name/bin
directory for each cluster node.
-
Start all nodes within the cluster.
At startup the Universal Messaging server
reads the remote_realms_bootstrap.conf file and updates its internal server data with the
new file entries. After the Universal Messaging server completes the reading of the file, it renames the file to
remote_realms_bootstrap_old.conf.
What to do next
To verify that the nodes in the cluster connect successfully, open Enterprise Manager and check if the cluster is
running.
