Pre-Upgrade Tasks

Before you upgrade Message Queue, perform the tasks described below.

• Verify Current Version Information

• Upgrade Message Queue Dependencies

• Back Up Message Queue Data

Verify Current Version Information

Verify the current version of Message Queue before you upgrade.

   imqbrokerd -version

2. The outputs that indicate the Message Queue version are:

   Release 5U1

   Sun Java System Message Queue 3.7 UR2

   Release 5

   Sun Java System Message Queue 3.7 UR1

Upgrade Message Queue 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 Message Queue has no hard upgrade dependencies, so upgrade of shared components is optional.

Back Up Message Queue Data

It is always a good practice to back up application data in a production environment before performing an upgrade. Note the location of the persistent store for the dynamic application data indicated in Table 8–2.
