Section
Column

 supports clustered form servers for both high availablity, load balancing and fault tolerance. The software can be installed and configured either as a stand-alone single form server or as a cluster of form servers behind an load balancer.

A Form Server Cluster is instrumental in heavy load scenarios where a single form server cannot handle the load alone. Clustering also enables fault tolerance should one node fail for either design time or use mode forms. If one form server is shutdown the form instances automatically get transferred to another running form server node.

 supports clusters running under either Apache web servers or Oracle Web Logic servers. This chapter details how to enable a  cluster running under an Apache web server.
