TYPE VARCHAR2(2) Snapshot type. Possible types are read-only (RO) or read/write (RW).
PARENT VARCHAR2(1024) Parent name used to create the snapshot. If the snapshot was created using the mount point as a base, parent name will be NULL. If the snapshot was created using an existing snapshot as the base, the parent name will be the name of the snapshot passed to the acfsutil snap create -p operation.
CON_ID NUMBER The ID of the container to which the data pertains. Possible values include:
  • 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

For this view, the value is always 0.

Note:

To display information about Oracle ACFS file systems or volumes that are located on nodes in an Oracle Flex ASM configuration, you must connect to the Oracle ASM proxy instance instead of the local Oracle ASM instance. For information about Oracle Flex ASM, refer to Oracle Automatic Storage Management Administrator's Guide.
