Sun Java Enterprise System 5 Installation Planning Guide

Upgrade of Product Components

A new capability has been implemented in the Java ES Release 5 to upgrade product components in a few special cases: Application Server, Message Queue, HADB, and Java DB. When the Java ES installer detects the previously installed release versions of these product components, it marks them as upgradable in the Component Selection page. If any of these four product components are selected, the installer will upgrade them using logic similar to that used for a fresh installation.

In particular, before upgrading 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 described in Synchronize All Shared Components, applies to non-zone operating systems, global zones, and all non-global zones.

However, there are three exceptions to this behavior:


Note –

There are a number of special cases or exceptions that might interfere with the installation or upgrade of product components in non-global zones. These cases are described in Special Cases or Exceptions.
