Adding New Members to an Existing Cluster
To add additional MashZone NextGen Servers to an existing cluster
1. Install the MashZone NextGen Server. See Installing Software AG Products for instructions.
3. If the cluster has a shared external configuration folder, add this folder and any subfolders to the classpath for the MashZone NextGen 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 MashZone NextGen Server in the cluster to the new MashZone NextGen Server.
6. Update the application server that hosts the new MashZone NextGen 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, MashZone NextGen 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 MashZone NextGen Server.
