2.8 Creating an Oracle RAC Database on Direct NFS

There are different configuration processes you must perform when installing and create an Oracle RAC database that uses Direct NFS (dNFS) for the database files.

Note:

• Starting with Oracle Database 21c, the name of Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is changed to Oracle Advanced Cluster File System (Oracle ACFS).
• Starting with Oracle Database 21c, the Oracle Grid Infrastructure feature Oracle Advanced Cluster File System (Oracle ACFS) is desupported with Microsoft Windows.

• For Oracle Real Application Clusters files, Oracle recommends that you use Oracle ASM. For generic files, depending on your use case, Oracle recommends that you either move files to Oracle Database File System (DBFS), or move files to Microsoft Windows shared files.

Caution:

Oracle ACFS and Oracle Automatic Storage Management Dynamic Volume Manager (Oracle ADVM) will not be accessible after you install or upgrade to Oracle Grid Infrastructure 21c.

• Performing a Software-Only Installation of Oracle Database
  In a software-only installation you install the Oracle Database software but do not create a database as part of the installation process.
• Using Oracle DBCA to Create and Configure the Oracle RAC Database
  Use Oracle Database Configuration Assistant (DBCA) to create an Oracle Real Application Clusters (Oracle RAC) database that uses Direct NFS for datafile storage.
• Enabling and Configuring Direct NFS
  You must manually enable the Direct NFS option after installing the Oracle Database software.
