What is that in-house Java application ? Running in a servlet container
(e.g. Tomcat), an EJB container (e.g. JBoss), ... ?
You should consider two things:
1) a cluster software to provide high availability of the cluster nodes
themselves (most importantly: heartbeat checking between the nodes +
migrating the cluster's IP address (the "VIP")) - I use heartbeat [1]
for that, works nicely and necessary RPMs are shipped with SUSE Linux
2) cluster your Java application: you can do that with Tomcat and JBoss
(and Weblogic, and Websphere, and Glassfish, and ...)

You _can_ cluster Oracle, but... you'll have to set up Oracle RAC, which
is both very complex *and* very expensive (different license fees).

The Java application is in a JAR that runs on a schedule (batch).
is there anything similar to RAC in the open-source community?
what would be missing with linux-ha compared to RAC?
