Understanding the Oracle RAC Directory Structure

When you install Oracle Database 12c Release 2 (12.2) with Oracle RAC, all subdirectories except for the Oracle Inventory directory, the Oracle Automatic Storage Management home (if applicable), and the Oracle Clusterware home, are under a top-level Oracle base directory. The Oracle home and admin directories are also located under the Oracle base directory.
