Can OC4J instances in a non-J2EE install types be clustered?
Due to an implementation limitation, only J2EE and Web Cache installations can get their configuration automatically replicated with Distributed Configuration Management (OracleAS DCM) tool and OracleAS Control. However, mod_oc4j can be manually configured to route from an OHS to multiple OC4J instances and this can work together replicating state between them no matter the type of install type that they reside at.
