High Availability and Disaster Recovery Configuration Guide for IBM Security Manager 6.x / 7.x

Summary

In order to ensure critical data is readily available or to reduce system downtime resulting from temporary or large-scale failures, many customers will have requirements to set up IBM Security Identity Manger (ISIM) in either a High Availability (HA) environment, a Disaster Recover (DR) environment or in both configurations.

This document discusses how to configure either ISIM 6.x or the ISIM 7.x Virtual Appliance (VA) for HA, DR or HA/DR environments. The deployment topology and configuration are consistent with current documentation for IBM Security Identity Manager (ISIM) 6.x /7.x. Both high availability and data replication features provided by the associated middleware are leveraged to provide a complete solution. This article covers the high availability configuration steps that were tested in Security Performance labs and describes fail-over scenarios for stand-by DB2 databases and stand-by Websphere Application Server (WAS) cluster systems. This document also details subject matter expert recommendations on configuring ISIM and its accompanying middleware in separate Data Centers for Disaster Recovery.
