Installing and Configuring the Sun Java System Message Queue

The Sun Java System Message Queue is a Java 2 Enterprise Edition (J2EE™) 1.3 compliant messaging service. This queue is designed to meet the needs of enterprise customers and run under the control of Sun Cluster software. This section describes the steps to install and enable the Sun Java System Message Queue to run as the Sun Cluster HA for Sun Java System Message Queue.

If you run the Sun Java System Message Queue and another messaging service server and they use the same network resources, configure them to listen on different ports. Otherwise, a port conflict might occur between the two services.

Use the following procedure to install the Sun Java System Message Queue.

How to Install the Sun Java System Message Queue

Use the following procedure to install the Sun Java System Message Queue. Only the sections that are specific to the Sun Java System Message Queue are included here. See the Sun Java System Message Queue for Solaris OS documentation for details.

Do not set the AUTOSTART property to YES in the /etc/imq/imqbrokerd.conf file. The AUTOSTART property is set to NO by default because Sun Cluster HA for Sun Java System Message Queue starts and stops the application after you have configured the data service.

1. Install the Sun Java System Message Queue package on all the nodes of the cluster if they are not already installed.

2. Identify a location on a global file system where you intend to keep your message queue (for example, /global/s1mq).

   You can create a separate directory for this file system.

3. On any node set IMQ_VARHOME and run the imqbrokerd command to create the configuration directory and files.

   # IMQ_VARHOME=/global/s1mq # export IMQ_VARHOME # imqbrokerd -name hamq1

4. Set the imq.portmapper.hostname property to the logical hostname by editing $IMQ_VARHOME/instances/hamq1/props/config.properties.
