Two issues arise when installing or uninstalling Enterprise Server with High Availability packages in a Global Zone:
HA packages get installed in all zones, which may not be desirable.
When uninstalling, HA, MQ, JDK packages get removed from all zones, which may not be desirable.
This problem does not occur when installing or uninstalling from a root local zone.
Perform installation and uninstallations from a local root zone rather than a global zone.
