Installation of Product Components

The Java ES installer can install product components as well as the shared components needed to support each product component. Before installing a selected product component, the installer checks for the existence of current and previous versions of shared components. If the installer detects that a shared component required by the selected component is of a previous version or is missing, the installer will upgrade all shared components currently installed and install any missing shared components required by the selected component. This behavior, which meets the requirements of Synchronization of Shared Components, applies to non-zone operating systems, global zones, and all non-global zones.

However, there are two exceptions to this behavior:

• In sparse root zones, some shared components cannot be installed or upgraded (see Shared Components and Sparse Root Zones), and installation is halted until such time as such shared components have been installed or upgraded in the global zone. The installer provides the following message: “The following shared components, required by the components you have selected, cannot be installed or upgraded in a sparse root zone. Please install or upgrade these shared components in the global zone before proceeding. Use the All Shared Components option.” For more information see Synchronize All Shared Components.

• In a global zone, if non-global zones are present, instead of upgrading all shared components currently installed and installing any missing shared components required by a selected component, the installer synchronizes all Java ES shared components, whether or not they are needed by any specific product component. This allows all shared components to be propagated to non-global zones, thus assuring that there is no intermixing of shared component versions in non-global zones.
