Summary :
When using Oracle Real Application Clusters (RAC) in SAP environments, a cluster file system such as the Oracle ASM cluster file system (ACFS) or a common NFS must be available to ensure high availability without single points of failure. Essential components including Oracle CRS Home (for specific versions), Oracle RDBMS Home, SAP Home, Voting Disks, and OCR must also be stored on the shared system for operational integrity. Load balancing is prohibited, and specific Oracle release combinations are stipulated for compatibility. Extensive testing in a replica test environment is strongly recommended to validate the installation and configuration. Supported configurations must adhere strictly to specifications provided in SAP’s guidance to ensure supported operation of RAC systems with the SAP environment.
