Oracle Fusion Middleware High Availability - Version to [Release Oracle11g]
Information in this document applies to any platform.
This document is limited to 11g. For 12c, see the Oracle Documentation for your version and the following White Paper:

Oracle offers both High Availability (HA) and Disaster Recovery (DR) solutions for Fusion Middleware (FMW) 11g.

HA solutions address maintaining a service in the event of loss of an individual process, resource or node - see:

Oracle Fusion Middleware High Availability Guide
11g Release 1 (11.1.1)
Part Number E10106-15
1 Introduction to High Availability
1.1 What is High Availability

In contrast, DR is intended to ensure continuity of service in the event of loss of a complete site - see:

Oracle Fusion Middleware Disaster Recovery Guide
11g Release 1 (11.1.1)
Part Number E15250-03
1 Disaster Recovery Introduction

There has been a recent trend to attempt to combine elements of HA and DR architectures into a single solution. This bulletin explores the supportability of such solutions for FMW 11g.


This bulletin is intended to be of use to systems architects, implementers and administrators, who are responsible for defining and building HA/DR FMW 11g systems.

It is assumed that the reader is already familiar with the HA and DR concepts outlined in the above-referenced documents.
