The configuration requirements in this section apply only to Sun Cluster HA for SAP DB.
If your data service configuration does not conform to these requirements, the data service configuration might not be supported.
For requirements that apply to all data services, see Configuration Guidelines for Sun Cluster Data Services in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.
Use SAP DB version 7.4 or compatible versions.
Configure Sun Cluster HA for SAP DB as a failover data service. You cannot configure Sun Cluster HA for SAP DB as a scalable data service. For more information, see the following sections:
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. For more information, see How to Register and Configure an SAP xserver Resource.
