Disk Group Templates
ALTER DISKGROUP dskgrp01 ALTER TEMPLATE
DBAHELPER1 ATTRIBUTES (COARSE);
To drop an existing template, use the DROP
TEMPLATE clause. This can be applied to one or more templates
from a disk group. System defined templates supplied by Oracle
cannot be dropped. Only user defined templates can be dropped.
To drop the DBAHELPER1 template, issue the
following command:
ALTER DISKGROUP dskgrp01 DROP TEMPLATE
DBAHELPER1;

Disk Group Directories
A disk group contains a hierarchical
directory structure with fully qualified file names

automatically created by ASM. To create more friendly aliases
for filenames, a directory
structure has to be created to support the
new naming conventions.
To create a new directory, use the ADD
DIRECTORY clause of the ALTER DISKGROUP command. The directory
path should begin with a plus (+) sign, followed by subdirectory
names separated by forward slash (/) characters.
An example using the dskgrp01 disk group
would be as follows:
