The following figure illustrates how components of the Geographic Edition configuration interrelate.
Figure 4 Overview of Geographic Edition Software Architecture
The clusters in a Geographic Edition configuration can run different versions of Oracle Solaris Cluster software, as long as the versions are no more than one consecutive release different. For example, the clusters in one Geographic Edition configuration could run either version 4.2 or 4.3, or run either version 4.2 or 4.1. But you cannot have clusters running either version 4.1 or 4.3 in the same Geographic Edition configuration.
You can install and remove the Geographic Edition software independently of the underlying Oracle Solaris Cluster installation. The installation and the uninstallation processes do not require an additional node reboot or cluster downtime.
