Pre-Upgrade Tasks

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

• Verify Current Version Information

• Upgrade Java DB Dependencies

• Backing Up Java DB Data

Verify Current Version Information

Verify the current version of Java DB before you upgrade.

To Verify Current Version Information

1. Type the following command:

   java -cp JavaDB-base\lib\derby.jar org.apache.derby.tools.sysinfo

   This command returns the Java DB version information.

   Release 5U1

   Java DB 10.2.2.1

   Release 5

   Java DB 10.1.3.1

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.
