SAP xserver Configuration Requirements

To enable client applications to access Sun Cluster HA for SAP DB, you must use SAP xserver. Configure SAP xserver as a scalable data service. Do not configure SAP xserver as a failover data service.

Configure SAP xserver so that SAP xserver starts on all nodes to which the SAP DB resource can fail over. To implement this configuration, ensure that the node list of the SAP xserver resource group contains all nodes that are in the node list of the SAP DB resource group.
