38.2.2. Dedicated JCA Backup Server
For the backup server, the
hornetq-configuration.xml is unchanged. Because there is no live server, you must ensure the hornetq-jboss-beans.xml instantiates all the beans needed. You configure this using the same configuration as in the live server, with the exception of changing the location of the hornetq-configuration.xml parameter for the Configuration bean.
Procedure 38.11. Configure Dedicated Backup Server
Follow this procedure to configure a dedicated HornetQ backup instance, located on a separate JBoss Enterprise Application Platform server.
Prerequisites
- A HornetQ Live Server, configured according to the procedures contained within Section 38.2.1, “Dedicated JCA Live Server”
- A correctly configured JBoss Enterprise Application Platform instance, installed on a separate server instance to the live server.
- HornetQ installed on the platform instance.
- On the backup server, navigate using the command line to
/extras/hornetq/. - Execute
sh ./switch.sh -Dbackup=true.The script executes and creates aproduction-backupserver profile in$JBOSS_HOME/server/ - Copy the
production-backupserver profile, and rename it toHornetQ_Dedicated_Backup. - Open
$JBOSS_HOME/server/HornetQ_Dedicated_Backup/hornetq/hornetq-configuration.xml - Add the <shared-store>true</shared-store> element as a child element to the <configuration> element.
- Change the data directory locations to match the following values:
- <large-messages-directory>/media/shared/data/large-messages</large-messages-directory>
- <bindings-directory>/media/shared/data/bindings</bindings-directory>
- <journal-directory>/media/shared/data/journal</journal-directory>
