Adding a Server Back into the Cluster
You can add a server back into a cluster by enabling clustering on the server again. When clustering was previously enabled, the server stored the configured settings in the server.cnf file in the Integration Server_directory /instances/instance_name/config directory.
Configuration information is stored on the Terracotta Server Array. If you re-enable clustering and specify the same Terracotta Server Array URLs and the same cluster name, Integration Server retrieves the cache configuration information from the Terracotta Server Array.
When you enable clustering, ensure that the server has the same licensed capabilities as the rest of the servers in the cluster.
To add a server back into the cluster
1. If it is not already running, start the Integration Server Administrator of the server you want to add back into the cluster. See webMethods Integration Server Administrator’s Guide if you need help with this step.
2. In the Settings menu of the navigation area, click Clustering.
3. Click Edit Cluster Settings.
4. Click Enable Cluster to turn clustering on for this server.
5. Make any changes you want to the configuration.
6. Click Save Settings.
7. Restart the server.
Note: | Until you restart the server, it will not appear in the list of cluster hosts on other Integration Servers in the cluster. |
Important: | If you are using guaranteed delivery, the server you are returning to the cluster might be offline. When a server is offline, it can only be accessed through a single, unpublished port. Before you can use the server, you must first bring it back online. See Bringing a Server Back Online for instructions. |
