The Java ES installer performs a simple pkgadd installation of the core Sun Cluster packages and sets up the /usr/cluster/bin directory. No configuration is done during installation, so your first postinstallation task is to configure the cluster framework as described in the Sun Cluster Software Installation Guide for Solaris OS.
During this phase, the scinstall utility verifies the Sun Cluster packages. If packages are missing, an error message is displayed. If this happens, you must verify that the correct Sun Cluster packages were installed. Refer to Chapter 5, List of Installable Packages, in Sun Java Enterprise System 5 Installation Reference for UNIX.
