E Directory Structure for Oracle Real Application Clusters Environments

This appendix describes the directory structures for Oracle Real Application Clusters (Oracle RAC) software environments. The topics in this appendix are:

E.1 Understanding the Oracle Real Application Clusters Directory Structure

When you install Oracle Database with Oracle RAC, all subdirectories are under a top-level Oracle base directory, which is named by default ORACLE_BASE. The ORACLE_HOME and ADMIN directories are also located under the Oracle base directory.

E.2 Directory Structures for Oracle Real Application Clusters

Table E-1 shows the hierarchical directory tree of a sample OFA-compliant database for Oracle RAC on Windows-based systems:
