Configure the primary companion for asymmetric configuration. From the secondary companion, issue:
sp_companion "primary_server_name", configure, with_proxydb, login_name, password
Where:
primary_server_name is the name of the primary Adaptive Server as defined in the interfaces file entry and in sysservers.
with_proxydb indicates that proxy databases are created on the secondary companion for all databases other than system databases. Any subsequent databases that are added also create proxy databases.
login_name is the name of the user performing this cluster operation (they must have the ha_role permission).
password is the password of the person performing this cluster operation.
This example configures an Adaptive Server named PERSONEL1 as a secondary companion:
sp_companion "MONEY1", configure, "Think2Odd", "password"
Server 'PERSONNEL1' is alive and cluster configured. Step: Access verified from Server:'PERSONEL1' to Server:'MONEY1'. Server 'MONEY1' is alive and cluster configured. Step: Access verified from Server:'MONEY1' to Server:'PERSONEL1'. (1 row affected) (1 row affected) (1 row affected) (1 row affected) ... (1 row affected) (1 row affected) (1 row affected) Step: Companion server's configuration check succeeded. Step: Server handshake succeeded. Step: Master device accessible from companion. Step: Added the servers 'PERSONEL1' and 'MONEY1' for cluster configuration. Step: Server configuration initialization succeeded. Step: Synchronizing Application Specific information from companion server Step: Synchronizing Roles from companion server Step: Synchronizing Login Roles from companion server Step: Synchronizing Remote Logins from companion server Step: Synchronizing Groups in sysusers from companion server Step: Synchronizing Sysattributes from companion server Step: Synchronizing server logins from companion server Step: Synchronizing server-wide privs from companion server Step: User information synchronization succeeded. Step: Server configured in normal companion mode.
If user databases already exist while you are using sp_companion, you see messages similar to these:
Step: Created proxy database ‘pubs2’ Step: Proxy status for database has been set. Please Checkpoint the database 'pubs2' Step: Server configured in normal companion mode” Starting companion watch thread
See “Asymmetric Companion Configuration” for more information about asymmetric configuration.
The login_name and password in sp_companion
configure cannot be null. After you successfully execute sp_companion
configure, it creates a new file, /etc/VRTSvcs/conf/config/ha_companion.remote_server_name.
Verify this file has read and write access only for the user who
runs the server. Otherwise, security is compromised.
