7.5 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. WebSphere Application Server, coupled with IBM HACMP for AIX, delivers a proven and reliable software portfolio for mission-critical On Demand Business applications.
