HA-OSCAR "High Availability Open Source Cluster Application Resources" is an open source project that aims to provide a combined power of High Availability and Performance Computing solution. Our goal is to enhance computing infrastructures such as Beowulf cluster systems, Web Servers, e.t.c for mission critical grade applications. To achieve high availability, component redundancy is adopted in HA OSCAR cluster to eliminate this single point of failure. HA-OSCAR incorporates a self-healing mechanism; failure detection & recovery, automatic failover and fail-back
