If we are configuring our application for high availability and disaster recover, it is mandatory to have failover configurations at DB datasource level as well. In this page, we described how to configure database failover in JBoss 7. Close watch below JBoss datasource configurations. The "connection-url" tag contains two connection urls with a delimiter "|". The delimiter character also required to mention with "url-delimiter" tag.

With this failover configuration, JBoss connects to the first specified DB. On any failure, JBoss tries to connect to second DB url.

<datasource jndi-name="java:jboss/jdbc/HADatasource" pool-name="HADatasource" 
												enabled="true" use-java-context="true">
	<connection-url>
		jdbc:oracle:thin:@db-host:db-port/service|jdbc:oracle:thin:@db-host:db-port/service
	</connection-url>
	<url-delimiter>|</url-delimiter>
