I currently have an application that runs Oracle under one SuSE server and Java in-house code in another SuSE server. I was wondering if anybody can suggest a cluster solution so I can have my Java code duplicated in two+ SuSE servers.
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 ...)

How about Oracle, can I cluster Oracle to run on two+ servers? I am trying to achieve not only higher availability but also put to work some hardware servers I have on the floor collecting dust.
You _can_ cluster Oracle, but... you'll have to set up Oracle RAC, which
is both very complex *and* very expensive (different license fees).
