This document discusses two ways to create directories within ASM disk groups in Oracle: using the ASMCMD utility or using SQLPlus connected to the ASM instance. It provides examples of using ASMCMD commands like mkdir to create directories within specific disk groups, and using SQL queries to create multiple directories at the same time within ASM.

1. CREATE DIRECTORY
UNDER ASM
DISKGROUP

2. In this activity, you will understand how to create directories
inside disk groups to place data. Unlike OS level commands,
Adding directories to ASM disk groups is little different.
There are two ways to do this:
Using ASMCMD utility
Using SQLPLUS (for ASM)

3. CREATE DIRECOTRY USING ASMCMD UTILITY
Type asmcmd at command prompt.
Under asmcmd, you can use many OS level commands like
ls – to list contents,
pwd – check present working directory,
mkdir – create new directory,.
rm – remove directory or file,
cp – copy file or directory

5. Let us create directory under RMANVOL diskgroup:

6. You can create multiple directories in one single command too
CREATE DIRECTORY USING SQLPLUS (FOR ASM)
Connect to Oracle (or grid) user and export Oracle home and
SID variables to point Grid home and ASM instance

7. Issue below SQL queries to create directories:
