Use the information in this section to plan the installation and configuration of Sun Cluster HA for SAP liveCache. The information in this section encourages you to think about the impact your decisions have on the installation and configuration of Sun Cluster HA for SAP liveCache.
Install liveCache on its own global device group, separate from the global device group for the APO Oracle database and SAP R/3 software. This separate global device group for liveCache ensures that the liveCache resource can depend on the HAStoragePlus resource for liveCache only.
If you want to run SAP xserver as any user other than user root, create that user on all nodes on which SAP xserver runs, and define this user in the Xserver_User extension property. SAP xserver starts and stops based on the user you identify in this extension property. The default for this extension property is user root.
Configure SAP xserver as a failover resource unless you are running multiple liveCache instances that overlap.
