Solaris Cluster HA for SAP liveCache Overview

Use the information in this section to understand how Solaris Cluster HA for SAP liveCache makes liveCache highly available.

For conceptual information on scalable services, see the Oracle Solaris Cluster Concepts Guide.

To eliminate a single point of failure in an SAP Advanced Planner & Optimizer (APO) System, Solaris Cluster HA for SAP liveCache provides fault monitoring and automatic failover for liveCache and fault monitoring and automatic restart for SAP xserver. The following table lists the data services that best protect SAP Supply Chain Management (SCM) components in a Solaris Cluster configuration. Figure 1-1 also illustrates the data services that best protect SAP SCM components in a Solaris Cluster configuration.
