    Abstract

    This IBM Redbooks publication provides detailed instructions and scripts on managing failover and switchback in a bidirectional Q replication environment for the AIX platform.

    A typical business scenario is used to showcase the bidirectional failover/switchback implementation. The book also includes a HADR high availability scenario for the source system in a Q replication environment involving unidirectional replication. Key considerations in designing and implementing such environments are discussed.

    This book is organized into the following topics:

    - High availability concepts

    - WebSphere Replication Server Q replication overview

    - Failover and switchback scenarios

    - HADR and Q replication coexistence scenario

    - Summary of code and scripts used in the scenarios

    - Exception processing in a bidirectional Q replication environment

    - Overview of HADR and DB2 Client Reroute
