Configuration Considerations

The configuration considerations in the subsections that follow affect the installation and configuration of Sun Cluster HA for SAP DB.

Device Group for the SAP DB Application

Ensure that you create a device group for the SAP DB application as follows:

• Install SAP DB on its own global device group. For more information, see Installing and Configuring SAP DB. This separate global device group for SAP DB ensures that the SAP DB resource can depend only on the HAStoragePlus resource for SAP DB.

• Create an HAStoragePlus resource for the global device group on which SAP DB is installed. For more information, see Configuring the HAStoragePlus Resource Type to Work With Sun Cluster HA for SAP DB.

• Ensure that the resource for Sun Cluster HA for SAP DB depends on the HAStoragePlus resource for the global device group on which SAP DB is installed. For more information, see Registering and Configuring Sun Cluster HA for SAP DB.

Administration of SAP xserver by a User Other Than Root

You might be required to administer SAP xserver as a user other than root. In this situation, you must create and define that user as follows:

• You must create that user on all cluster nodes that master SAP xserver.

• You must define that user when you register and configure Sun Cluster HA for SAP DB. For more information, see Registering and Configuring Sun Cluster HA for SAP DB.
