Purpose

High-availability across distributed application and database clusters is natively supported by OSM application architecture in a typical single site deployment; OSM operation is continuous regardless of the failure of a single application or database node in the OSM site. In some cases however, continuation of operation with minimal loss of service is required in the event of complete failure in the primary OSM/OSS application stack, e.g. due to natural disaster.

This document describes a generic architecture for OSM across multiple geographically redundant sites in a primary-standby, i.e. active-passive, deployment. The architecture described in this document is intended to provide guidelines for projects with geographically redundant site availability requirements. This document does not include information for high-availability installation of other OSS applications that may be deployed with OSM. The following information is included:
» Geographically redundant (GR) architecture for OSM
» Installation, configuration, and operational best practices
» Switchover and failover test procedures and test results.

Scope

This document is intended for OSM architects, administrators, developers, customer support, and testers. The reader should be familiar with Oracle Enterprise Linux, OSM installation and operation, Oracle database, Oracle Data Guard, and Oracle WebLogic prior to reading this document. This document is applicable for OSM 7.2.4 and up to OSM 7.3.5.0.  For all OSM release 7.3.5.0 and up using WebLogic 12.2 and higher, please contact Oracle Support for more detailed and up to date information.
