    Maintaining maximum system uptime is increasingly critical to the success of on demand computing. Unfortunately, many off-the-shelf solutions for high availability (HA) are expensive and require expertise. This series of five articles offers a lower-cost alternative to achieving HA services using publicly available software.

    The step-by-step procedures in this series show how to build a highly available Apache Web server, WebSphere® MQ queue manager, LoadLeveler cluster, WebSphere Application Server cluster, and DB2® Universal Database on LinuxTM. A systems administrator can learn to use and maintain this system with minimal time investment. The techniques described in this series also apply to any number of services on Linux.

    To get the most out of this series, you should have a basic understanding of WebSphere MQ, WebSphere Application Server, IBM LoadLeveler, DB2 Universal Database, and high-availability clusters.
