Subprograms

Creates a file system of type specified by file system type and name similar to mkfs on Unix

dbms_fs.make_oracle_fs(
fstype IN VARCHAR2,
fsname IN VARCHAR2,
fsoptions IN VARCHAR2); -- comma separated file system create options

exec dbms_fs.make_oracle_fs('FUBAR', 'FUBAR', 'FUBAR');

The fact that this runs successfully, and there are no dependencies, unfortunately tells us nothing about it.

MOUNT_ORACLE_FS

Mount an Oracle file system on the specified mount point similar to mount in Unix

dbms_fs.mount_oracle_fs (
fstype        IN VARCHAR2,
fsname        IN VARCHAR2,
mount_point   IN VARCHAR2,
mount_options IN VARCHAR2);

exec dbms_fs.mount_oracle_fs('FUBAR', 'FUBAR', '/fubar', 'FUBAR');

-- Doing this hang the session and the system ... SYSDBA can log on but a SHUTDOWN IMMEDIATE does not work forcing an ABORT.

UNMOUNT_ORACLE_FS

Unmount an Oracle file system on the specified mount point similar to umount in Unix

dbms_fs.unmount_oracle_fs(
fsname IN VARCHAR2,
mount_point IN VARCHAR2);

exec dbms_fs.unmount_oracle_fs('FUBAR', '/fubar');

-- Doing this hang the session and the system ... SYSDBA can log on but a SHUTDOWN IMMEDIATE does not work forcing an ABORT.
