## HA for SAP MaxDB Overview

To eliminate single points of failure in an SAP MaxDB system, HA for SAP MaxDB provides the following features:

- Fault monitoring and automatic failover for the SAP MaxDB application. You must configure HA for SAP MaxDB as a failover data service.

- Fault monitoring and automatic restart for SAP xserver. You must configure SAP xserver as a multiple master data service.

For conceptual information about failover data services and multiple master data services, see the Oracle Solaris Cluster Concepts Guide.

Each component of SAP MaxDB has data service that protects the component when the component is configured in Oracle Solaris Cluster. See the following table.

Note - The files that are associated with the `SUNW.sap_xserver` resource type are supplied with the Oracle Solaris Cluster HA for SAP liveCache data service. The Oracle Solaris Cluster HA for SAP liveCache data service is installed when you install HA for SAP MaxDB data service.
