8.1 Sun Cluster HA for Netscape Overview

The Sun Cluster HA for Netscape data services consist of a group of Netscape^TM applications that can be made highly available by running them in the Sun Cluster environment. Table 8-1 displays the data service application and its associated highly available data service.

Table 8-1 Sun Cluster HA for Netscape Data Services

Netscape Application	Highly Available Data Service Name	Package Name

See the Sun Cluster 2.2 Release Notes for a list of the supported release levels for the data services.

Table 8-2 describes the high-level procedures to set up Netscape data service applications to run with Sun Cluster.

Note -

If you are running multiple data services in your Sun Cluster configuration, you can set up the data services in any order, with one exception: if you use Sun Cluster HA for DNS, you must set it up before setting up Sun Cluster HA for NFS. DNS software is included in the Solaris environment. See Chapter 12, Setting Up and Administering Sun Cluster HA for DNS, for details. If the cluster is to obtain the DNS service from another server, then configure the cluster to be a DNS client first.

After installation, do not manually start and stop the Netscape data services. Once started, they are controlled by Sun Cluster.

The procedures described in this chapter assume that you are familiar with the Sun Cluster concepts of disksets, logical hosts, physical hosts, switchover, takeover, and data services.
