Note the following general restrictions and guidelines about Oracle ACFS:

• Oracle Automatic Storage Management Cluster File System (Oracle ACFS) provides a general purpose file system. You can place Oracle Database binaries and Oracle Database files on this system, but you cannot place Oracle Clusterware files on Oracle ACFS.

  For policy-managed Oracle Flex Cluster databases, be aware that Oracle ACFS can run on Hub Nodes, but cannot run on Leaf Nodes. For this reason, Oracle RAC binaries cannot be placed on Oracle ACFS on Leaf Nodes.

• Oracle Restart does not support root-based Oracle Clusterware resources. For this reason, the following restrictions apply if you run Oracle ACFS on an Oracle Restart Configuration

  • You must manually load and unload Oracle ACFS drivers.

  • You must manually mount and unmount Oracle ACFS file systems, after the Oracle ASM instance is running

  • With Oracle Restart no Oracle Grid Infrastructure resources can be defined for filesystems. Therefore ACFS filesystems cannot be used for database homes or data files.

  • You cannot place Oracle ACFS database home filesystems into the Oracle ACFS mount registry. The mount registry is entirely removed with Oracle Grid Infrastructure 12c release 1.

• You cannot store Oracle Clusterware binaries and files on Oracle ACFS.

• Starting with Oracle Grid Infrastructure 12c Release 1 (12.1) for a cluster, creating Oracle data files on an Oracle ACFS file system is supported.

• You can store Oracle Database binaries, data files, and administrative files (for example, trace files) on Oracle ACFS.
