Platform Issues

This section describes issues specific to the Solaris, Linux, and Windows platforms.

Solaris

On the Solaris platform, you can install Message Queue 3.7 UR1 on top of Versions 3.0.x, 3.5, and 3.6, and your existing instance data (configuration properties, file-based persistent data store, log files, flat-file user repository, and access control properties file) will be used by Version 3.7 UR1 (see Compatibility Issues).

If you depended on the .jar files listed below to be in their Version 3.0.x locations, please note that they have been moved to the /usr/share/lib directory:

In Message Queue 3.0, these files were in the /usr/share/lib/imq directory; in Message Queue 3.0.1, they were in the /usr/share/lib directory with symbolic links in the /usr/share/lib/imq directory. In Message Queue 3.7 UR1, there are no symbolic links files.

Linux

On the Linux platform, you should not try to install Message Queue 3.7 UR1 on top of earlier versions, but should instead uninstall any earlier versions of Message Queue before installing Version 3.7 UR1. This is because the installed directory structure has been changed as of Message Queue 3.6, and this complicates the migration of instance data (configuration properties, file-based persistent data store, log files, flat-file user repository, and access control properties file) from Versions 3.0.x and 3.5 to Version 3.7 UR1. A utility program, mqmigrate, is provided to ease the migration of these data files from versions earlier than 3.6 (see Finding and Removing Earlier Message Queue Versions). (If you are upgrading from Message Queue 3.6, you do not need to use the mqmigrate utility, since the files are already in the correct locations.) After migrating the instance data files if necessary, you should uninstall any Message Queue 3.0.x, 3.5, and 3.6 Red Hat Package Manager (RPM) packages and then install the 3.7 UR1 RPM packages using mqinstall.

Scripts that use hard-coded paths to the Linux installations of Message Queue Versions 3.0.x or 3.5 will need to be changed to the new directory location for Message Queue 3.7 UR1. If you need symbolic links that point the old locations to the new locations, you must install the sun-mq-compat RPM package; this package may not be supported in future releases.

Windows

The upgrade procedure for Message Queue 3.7 UR1on the Windows platform varies depending on the previously installed version of Message Queue, as described in the following sections.

Message Queue 3.5 and 3.6

Before installingMessage Queue 3.7 UR1, you should uninstall any existing installations of Message Queue 3.5 or 3.6. If you are installing Version 3.7 UR1 in a different location than Versions 3.5 or 3.6, you must first move any instance data (configuration properties, file-based persistent data store, log files, flat-file user repository, and access control properties file) that you want to preserve from its old location, corresponding to the old value of the directory variable IMQ_VARHOME/instances/, to the new location, corresponding to the new value of IMQ_VARHOME/instances.

Message Queue 3.0.x

If you are upgrading from Message Queue 3.0.x to 3.7 UR1, it is likely that you will have to manually migrate any previous instance data (configuration properties, file-based persistent data store, log files, flat-file user repository, and access control properties file) from its Message Queue 3.0.x location to the new Message Queue 3.7 UR1 location, specified as follows:

IMQ_VARHOME\instances\instanceName
