Linux User Accounts

This section provides information about Linux user accounts that are provisioned on an Oracle Database Classic Cloud Service database deployment that uses Oracle Data Guard.

Every Database Classic Cloud Service compute node is provisioned with the following operating system user accounts.

User	Description
opc	The system administrator account you use with the sudo command to perform operations that require root-user access.
oracle	The Oracle Database administrator account you use to access the system and perform non-root database administration tasks. A home directory, /home/oracle, is created for this user. This user cannot use the sudo command to perform operations that require root-user access.
root	The root administrator for the system. You do not have direct access to this account. To perform operations that require root-user access, use the sudo command as the opc user.

The following environment variables are created for the opc and oracle users.
