Creating Required Operating System Groups and Users

If you are installing Oracle software for the first time and on the products that you are installing, create several operating system groups and users.

You can choose to create one administrative user and use one group for operating system authentication for all system privileges on the storage and database tiers. For example, you can designate the oracle user to be the Oracle Installation user for all Oracle software and use only the ORA_DBA group for authentication. You can also create custom configuration groups and users based on job role separation that divide access privileges.

Log in as an Administrator user, and use the following instructions to create the Oracle Installation user for Oracle Database.
