The Server Configuration Tool’s System Configuration>Partners settings include Type, which you can use to define the type of server architecture to which the server you are configuring belongs. For example, if you are configuring a server that is to be a Standby server in a Triple Standby architecture, you should set the Type to Triple Standby.
The Type setting defines the server’s role in the system architecture and can be set to:
- Lone Server—The server is a stand-alone server (see Lone Server Architecture). The server you are configuring does not connect to any other server in the system.
- Hot-Standby Pair—The server is part of a Hot-Standby Pair (either the Main server or the Standby server). For more information, see Hot-Standby Pair Architecture.
- Triple Standby—The server is part of a Triple Standby architecture (either the Main server or one of the two Standby servers). For more information, see Triple Standby Architecture.
- Permanent Standby—The server is a Permanent Standby that is used in conjunction with a Hot-Standby Pair or Triple Standby architecture (see Permanent Standby Servers).
- DMZ Permanent Standby—The server is a Permanent Standby that is used in conjunction with a Hot-Standby Pair or Triple Standby architecture and has the DMZ (De-militarized Zone) setting enabled (see De-Militarized Zone (DMZ) Permanent Standby Servers).
WARNINGCOMPLETE LOSS OF CONFIGURATION
When setting up a main-standby system, make sure that you restart the servers in the correct order if objects are already configured in your database. Make sure that the server with objects already configured is started first and is running as main, then start the partner servers and allow them to synchronize with the main server.
Failure to follow these instructions can result in death, serious injury, or equipment damage. Failure to start the servers in the correct order can result in the complete loss of configuration from the system, requiring recovery from a backup.
