Decision Flowchart for OracleAS 10g (9.0.4)Infrastructure Highly Available Architectures

This “animated guide” is intended to provide System architects an overview of the various HA architectures and a method to choose an architecture suitable to their requirements. Please read “OracleAS 10g (9.0.4) Infrastructure Highly Available Architectures” white paper for a detailed description of every topology described in this flow chart
