A shared component synchronization option is provided to meet situations in which all shared components must be synchronized. When the All Shared Components option is selected, the installer will upgrade all shared components currently installed and install any missing shared components, whether or not they are needed by any specific product component. This option applies to global zones and whole root zones, but not to sparse root zones.
The All Shared Components option, is needed in the following two zone-based scenarios:
Manually upgrading product components. The All Shared Components option is needed to perform the shared component installation and upgrade needed when upgrading product components that cannot be upgraded using the Java ES installer.
Installations or Upgrades in a Sparse Root Zone. Some shared components cannot be installed in default sparse root zones. (For details, see Installation of Product Components and Upgrade of Product Components.) Hence when running the installer in sparse root zones, you might first be required to synchronize shared components in the global zone, depending on the shared components involved. You use the All Shared Components option in the global zone to perform the shared component installation and upgrade required in this case.
