Overview of a Shared Installation

In a shared 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 common $SYBASE directory.

• All server binaries (for example dataserver) and all scripts (for example installmaster).

• All configuration files, including the cluster input file.
• The interfaces file, unless LDAP is used for server lookup.
• A quorum device used to coordinate the instances with the cluster.
