4.3 HACMP

In general, High Availability is achieved by making systems redundant. The more system redundancy, the higher the level of availability that can be achieved. IBM HACMP for AIX provides a highly available computing environment by adding software and redundant hardware components. It automatically switches applications and data from one system to another in an HACMP cluster after a hardware or software failure.

In a WebSphere Commerce environment, HACMP is most commonly used for the database tier. For more detailed information about HACMP setup, refer to the HACMP documentation available at:
