Configuration Considerations

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

Device Group for the MaxDB Application

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

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

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

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

Dependencies of the MaxDB Application on SAP xserver

Configure MaxDB so that MaxDB starts only on a node where SAP xserver is running. To implement this configuration, configure resources and resource groups as follows:

• Ensure that the resource for MaxDB depends on the resource for SAP xserver.

• Create on the MaxDB resource group a strong positive affinity for the SAP xserver resource group.

For more information, see Registering and Configuring Sun Cluster HA for MaxDB.

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 or zones that master SAP xserver.

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