Understanding the Oracle RAC Directory Structure
When you install Oracle Database 19c 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.
