Sun Cluster HA for PostgreSQL Overview

Sun Cluster HA for PostgreSQL enables the Sun Cluster software to manage PostgreSQL by providing components to perform the orderly startup, shutdown, and fault monitoring of PostgreSQL.

You can configure Sun Cluster HA for PostgreSQL as a failover service. You cannot configure Sun Cluster HA for PostgreSQL as a multiple-masters service or as a scalable service.

When a PostgreSQL database cluster is managed by the Sun Cluster HA for PostgreSQL data service, the PostgreSQL instance becomes a failover PostgreSQL resource across the Sun Cluster nodes. The failover is managed by the Sun Cluster HA for PostgreSQL data service, which runs within the global zone and failover zones.

For conceptual information about failover data services, multiple-masters data services, and scalable data services, see Sun Cluster Concepts Guide for Solaris OS.
