This article provides basic installation requirements and tasks for Oracle customers intending to install Oracle RAC Database with IBM Spectrum Scale file system on IBM POWER servers with the AIX operating system.
Please see the performance tuning and availability recommendations after the installation section.

Acceptable uses of the IBM Spectrum Scale (GPFS) file system include:

1. Shared ORACLE_HOME directory for Oracle database installation
2. Shared database files for tablespaces and other general database object containers
3. Oracle Clusterware registry and membership files (i.e. Oracle Cluster Registry (OCR) and Vote Disks)*
