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 role is automatically transferred to the secondary server.
Before you begin
- Ensure that you have an expansion server available. 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, move it to an expansion
server.NOTE: If you must host the plugin role on the main server, you must also configure the Directory failover. For more information, see Directory failover and load balancing.
- Ensure that the plugin role and the plugin role database are not hosted on the same server. For more information, see Connecting roles to remote database servers.
What you should know
- For more information, see Role failover on the TechDoc Hub.IMPORTANT: Security Center does not handle the failover of role databases. For roles that connect to a database, the database server must be hosted on a third computer, separate from the servers hosting the role. All role servers must have read and write access to the database server. To protect your data, perform regular backups of the role database.
- If the plugin is configured to use HTTPS, the Events certificate needs to be valid for the main and failover server. The option to Create a self-signed certificate will not work as that certificate would be only valid for the server where the plugin is currently running.
