22.1.1 OFS Client Interface
The OFS interface includes views and procedures that support OFS operations.
22.1.1.1 DBMS_FS Package
The DBMS_FS
package enables users to perform operations on
Oracle file system (make, mount, unmount and destroy) in the Oracle database.
See Also:
Oracle Database PL/SQL Packages and Types Reference for more information about Oracle OFS procedures.
The following example illustrates the use of DBMS_FS
package.
BEGIN
DBMS_FS.MAKE_ORACLE_FS (
fstype => 'dbfs',
fsname => 'dbfs_fs1',
mount_options => 'TABLESPACE=dbfs_fs1_tbspc');
END;
/
BEGIN
DBMS_FS.MOUNT_ORACLE_FS (
fstype => 'dbfs',
fsname => 'dbfs_fs1',
mount_point => '/oracle/dbfs/testfs',
mount_options => 'default_permissions, allow_other, persist');
END;
/
/************** Now you can access the file system. All the FS operations go here ***************/
BEGIN
DBMS_FS.UNMOUNT_ORACLE_FS (
fsname => 'dbfs_fs1',
mount_point => '/oracle/dbfs/testfs',
mount_options => 'force');
END;
/
BEGIN
DBMS_FS.DESTROY_ORACLE_FS (
fstype => 'dbfs',
fsname => 'dbfs_fs1');
END;
/
