To improve the availability of your plugin role, you can add a secondary server on standby. If the primary server hosting the role becomes unavailable, the secondary server is automatically used.
Before you begin
- Ensure that you have an expansion server available as a secondary server for your plugin role. If you do not have an expansion server available, add an expansion server to your system.
- If your plugin role is hosted on the
main server, you must first move it to an expansion
server.NOTE: If you must host the plugin role on the main server, configuring the plugin role failover is not enough: you must also configure the Directory failover. Role failover is managed by the Directory role, and Directory failover is managed by the Directory Manager role. For more information, see Directory failover and load balancing.
