OC4J Standalone is for use by development and small-medium scale production deployments. Specifically, OC4J Standalone supports HTTP and HTTPS natively without the use of Oracle HTTP Server. It does not have support for load balancing, clustering, or management through Oracle Enterprise Manager 10g. To use those features, customers must install one of the Oracle Application Server installation types, such as J2EE + WebCache. The standalone version is supported in a single instance, single JVM, and single machine configuration.
