In a private installation, each instance of Adaptive Server
in the cluster shares:
-
All databases and database
devices (for example, all instances share the same master database)
-
A quorum device used to coordinate the instances
with the cluster
In a private configuration, each instance maintains its own:
-
$SYBASE directory
-
Interfaces file, unless LDAP is used for server
lookup
-
Server configuration file
Note:
Although each instance has its own server configuration
file, the quorum device maintains the master configuration file.
Adaptive Server uses the master configuration file to ensure that
each instance has the latest version of this file.
