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

Message Queue Data

Message Queue, like other Java ES components, makes use of various kinds of data that for any specific upgrade might need to be migrated to an upgraded version. Table 8–2 shows the type of data that could be impacted by an upgrade of Message Queue software.

In the table, Instance-Name identifies the name of the Message Queue broker instance with which the data is associated and MessageQueue-base is the installation directory for Message Queue.

For Java ES 5 Update 1, C:\Program Files\Sun\JavaES5\mq is the default installation location for Message Queue . For Java ES 4, C:\Sun\MessageQueue is the default installation location.
