Sun Java Enterprise System 5 Update 1 Upgrade Guide for Microsoft Windows

Pre-Upgrade Tasks

Before you upgrade Java DB, perform the tasks described below.

Verify Current Version Information

Verify the current version of Java DB before you upgrade.

ProcedureTo Verify Current Version Information

  1. Type the following command:

    java -cp JavaDB-base\lib\derby.jar

    This command returns the Java DB version information.

    Release 5U1

    Java DB

    Release 5

    Java DB

Upgrade Java DB Dependencies

It is generally recommended that all Java ES components on a computer system (and in a computing environment) be upgraded to Release 5U1. Release 5U1 Java DB has no hard upgrade dependencies, so upgrade of shared components is optional. However, the upgrade of Java DB to Release 5U1 requires that Windows Installer patch (126910–02) is already applied.

Backing Up Java DB Data

The Java DB upgrade from Release 5 to Release 5U1 does not modify the Release 5 configuration data. However, for the sake of security, you should back up your entire Java DB installation and your data.
