Adding a Server Back into a Stateful Cluster

Software AG Products 10.7 | Integrating On-Premises and Cloud Applications | Clustering | Managing Server Clustering | Adding a Server Back into a Stateful Cluster

You can add a server back into a cluster by re-enabling clustering on the server. 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.

Distributed caching 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 re-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. In Integration Server Administrator, go to Settings > Clustering > Edit Cluster Settings and click Enable Cluster.

2. Change the settings to enable clustering.

3. Click Save Settings and then 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.

4. If you are using guaranteed delivery, the server you are returning to the cluster might be offline. Before you can use the server, bring it back online. For instructions, see Bringing a Server Back Online to a Stateful or Stateless Cluster.
