Because Message Queue is installed with other products (such as Solaris 9, Solaris 10, and Sun Java System Application Server), you should check whether Message Queue has already been installed on your system. To do so, enter the following command:
imqbrokerd -version
If Message Queue is already installed, the version number is displayed.
If you find that a previous installation already exists on your system, see Upgrading From Previous Versionsfor information on upgrading to Message Queue 3.7 UR1.
