Adding New Members to an Existing Cluster

Appendix : Administration : Business Analytics Server Administration : Deploying Business Analytics Instances, Clusters or Artifacts : Clustering Business Analytics Servers : Adding New Members to an Existing Cluster

To add additional Business Analytics Servers to an existing cluster

1. Install the Business Analytics Server. See Installing Software AG Products for instructions.

2. Configure the Business Analytics Server to use the shared Business Analytics Repository for the cluster. See Share an Existing Business Analytics Repository for instructions.

3. If the cluster has a shared external configuration folder, add this folder and any subfolders to the classpath for the Business Analytics Server’s application server to enable access to this shared configuration.

Depending on your application server, you may update the classpath in the administration console, in configuration files or in the startup script for the application server. See documentation for your application server for more information.

4. If the cluster does not have a shared external configuration folder, copy the configuration and extension files from an existing Business Analytics Server in the cluster to the new Business Analytics Server.

See Business Analytics File-Based Configuration and Extensions for a list of files and folders to copy.

5. Copy the server configuration that cannot be shared from an existing Business Analytics Server in the cluster to the new Business Analytics Server. See Business Analytics File-Based Configuration and Extensions for details on the files and locations for this step.

6. Update the application server that hosts the new Business Analytics Server with the same cluster configuration as other cluster members.

In addition to the basic cluster configuration required by your application server and load balancer, Business Analytics has a single requirement for application-layer cluster configuration. You must either:

Enable session replication in each application server in the cluster.

Enable session affinity, sometimes also called ’sticky sessions,’ in the load balancer.

Or do both.

See documentation for your application server and/or load balancer for information on how to do this.

7. Restart the new Business Analytics Server.
