Oracle ASM - Create ASMDBA Account and Groups

Oracle ASM - Create ASMDBA Account and Groups

Colleagues hello to all.

In today's article, we'll talk about what kind of account is needed and what groups are needed for the normal operation of Oracle Automatic Storage Management.

When you install Oracle Automatic Storage Management on a server for the first time, before installing you need to make sure that the account and groups have been created on the server. This will allow you to successfully apply the necessary security settings and settings to the software without having to change the settings for other users on the server.


The first thing we need to do is create an account on the server. Oracle recommends using an account called grid.

Create an account on the server.

$. useradd grid


After creating the grid account, the next step is to create the necessary groups in the operating system.

List of required groups and their descriptions.

  • asmdba - Provides access to files managed by Oracle ASM.
  • asmadmin - Administrative access to the Oracle ASM instance.
  • asmoper - Restricted set of administrative privileges, starting and stopping an Oracle ASM instance.
  • oinstall - Primary group for installing Oracle ASM software as an Oracle Inventory group.

Creating groups.

$. groupadd oinstall
$. groupadd asmdba
$. groupadd asmadmin
$. groupadd asmoper


The next step is to add our grid account to each of the groups. In order to do this, we need to use a Linux command called usermod.

Add user to groups.

$. usermod -a -G oinstall grid
$. usermod -a -G asmdba grid
$. usermod -a -G asmadmin grid
$. usermod -a -G asmoper grid


Now after all our steps, you can now try installing Oracle Grid Infrastructure.

Thank you all, I hope that my article helped you in some way.
