Subprograms

DESTROY_ORACLE_FS	LIST_FILES	MOUNT_ORACLE_FS
FS_EXISTS	MAKE_ORACLE_FS	UNMOUNT_ORACLE_FS

DESTROY_ORACLE_FS

Drops a file system of type specified by file system type and name similar to mkfs on Unix dbms_fs.destroy_oracle_fs( fstype IN VARCHAR2, fsname IN VARCHAR2);

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

FS_EXISTS

Returns 1 if file system exists, 0 if not dbms_fs.fs_exists(fsname IN VARCHAR2) RETURN INTEGER; PRAGMA SUPPLEMENTAL_LOG_DATA(fs_exists, READ_ONLY);

TBD

LIST_FILES

Provides all available file details present within a directory or subdirectories dbms_fs.list_files(objdir_path IN VARCHAR2) RETURN listdir_entries_t PIPELINED; PRAGMA SUPPLEMENTAL_LOG_DATA(list_files, READ_ONLY);

TBD

MAKE_ORACLE_FS

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.
