To Connect Brokers Using Instance Configuration Files

1. For each broker in the cluster:

   1. Start the broker at least once, using the imqbrokerd command.

      The first time a broker instance is run, an instance configuration file (config.properties) is automatically created.

   2. Shut down the broker.

      Use the imqcmd shutdown bkr command.

   3. Edit the instance configuration file to specify the broker’s high-availability-related configuration properties.

      Enhanced Broker Cluster Properties shows the required property values. Be sure to set the brokerid property uniquely for each broker.

   4. Specify any additional, vendor-specific JDBC configuration properties that might be needed.

      The vendor-specific properties required for MySQL and HADB are shown in Example 8–1 and Example 8–2, respectively.

2. Place a copy of, or a symbolic link to, your JDBC driver’s .jar file in the Message Queue external resource files directory, depending on your platform (see Appendix A, Platform-Specific Locations of Message Queue Data):

   Solaris: /usr/share/lib/imq/ext

   
   

   Linux: /opt/sun/mq/share/lib/ext

   
   

   AIX: IMQ_HOME/lib/ext

   
   

   Windows: IMQ_HOME\lib\ext

   
   

3. Create the database schema needed for Message Queue persistence.

   Use the imqdbmgr create tbl command; see Database Manager Utility.

4. Restart each broker with the imqbrokerd command.

   The brokers will automatically register themselves into the cluster on startup.
