After you configure the companions for asymmetric fail over, you can set them up for symmetric configuration. In a symmetric configuration, both servers act as primary and secondary companions. See Figure 3-2 for a description of symmetric configuration.
Issue sp_companion from the secondary companion to configure it for symmetric configuration. You can use the same syntax as the asymmetric setup, except you cannot add with_proxydb.
The following example adds an Adaptive Server named MONEY1 as the secondary companion to the Adaptive Server named PERSONNEL1. Log in to the primary server MONEY1, and enter:
sp_companion 'PERSONNEL1', configure, go
Log in to the secondary server PERSONNEL1, and enter:
sp_companion “MONEY1”, configure go
Server 'MONEY1' is alive and cluster configured. Step: Access verified from Server:'MONEY1' to Server:'PERSONNEL1' Server 'PERSONNEL1' is alive and cluster configured. Step: Access verified from Server:'PERSONNEL1' to Server:'MONEY1' (1 row affected) (1 row affected) (1 row affected) (1 row affected) (1 row affected) (1 row affected) ..... Step: Companion servers configuration check succeeded Step: Server handshake succeeded Step: Master device accessible from companion Step: Added the servers 'MONEY1' and 'PERSONNEL1' for cluster config Step: Server configuration initialization succeeded Step: Synchronizing server logins from companion server Step: Synchronizing remoteserver from companion server Step: Synchronizing roles from companion server Step: Synchronizing server-wide privs from companion server Step: User information syncup succeeded Step: Server configured in normal companion mode
