You can install Sun Cluster Geographic Edition software on a running cluster without disruption. Because the Sun Cluster Geographic Edition software installation process does not require you to restart Sun Cluster software, the cluster remains in production with services running.
The Sun Java Enterprise System (Java ES) installer program offers two interactive installation modes, graphical user interface (GUI) and text-based interface. The graphical mode provides a wizard that guides you, step by step, through the tasks that you need to perform to install the Sun Cluster Geographic Edition components. The text-based mode provides the same functions that the GUI provides. However, this mode prompts you for responses on a line-by-line basis, rather than by means of a wizard.
Ensure that you have installed all the required patches for your cluster configuration on each node of every cluster before you start installing the software. See Required Patches in Sun Cluster Geographic Edition 3.2 Release Notes for the location of patches and installation instructions.
You must install Sun Cluster Geographic Edition software on all nodes of all clusters in a partnership.
