Oracle Fusion Middleware High Availability - Version 10.1.2.0.0 to 10.1.4.3.0 [Release AS10gR2 to AS10gR3] Oracle Fusion Middleware - Version 10.1.2.0.0 to 10.1.4.3.0 [Release AS10gR2 to AS10gR3] Information in this document applies to any platform.
Oracle Application Server 10g Enterprise Edition - Version: 10.1.2.0.0 to 10.1.4.3.0
The base OracleAS architecture supports many availability features, such as automatic process monitoring and restart (OPMN), application server backup and recovery (via scripts or AS Console). It does not, however, provide complete high availability. Several single points of failure exist. To eliminate them, redundancy has to be provided for each component. This can be achieved by extending the base architecture with additional high availability architectures
The objective of this article is to provide an overview and a roadmap with regards to the topic of Oracle Application Server High Availability (HA). This is a complex subject area which is documented in a number of different places. The article contains:
a clear outline of what should be considered before embarking on an OracleAS HA implementation
links to the salient documentation
hints and tips
The article does not intend to provide a step by step technical guide to implementing the various OracleAS HA topologies as this detail can be ascertained from the documentation.
The article is intended for system architects / administrators, consultants, support engineers who first getting to know the subject of OracleAS High Availability and are looking for a good place to start.
The reader should already be familiar with the basic Oracle Application Server architecture and different install types.
