This section provides information about Linux user accounts that are provisioned on Oracle Database Exadata Cloud at Customer .
Every Exadata Cloud at Customer compute node is provisioned with the following operating system user accounts.
The system administrator account you use in conjunction with the sudo command to gain root user access to your compute nodes.
The Oracle Database administrator account you use to access the system and perform 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.
The root administrator for the system. You do not have direct access to this account. To perform operations that require root user access, execute sudo -s as the opc user.
The Oracle Grid Infrastructure administrator account you use to perform ASM and Oracle Clusterware administration tasks. A home directory, /home/grid , is created for this user. This user cannot use the sudo command to perform operations that require root user access. You do not have direct access to this account. To perform operations that require grid user access, execute sudo -s as the opc user to get root access, and then execute su — grid to become the grid user.
The following environment variable settings are created for the opc , oracle and grid users.
The home directory of the user, either /home/opc , /home/oracle or /home/grid .
The host name of the compute node.
The system language, en_US.UTF-8 .

This topic does not apply to Oracle Cloud Infrastructure or to Oracle Cloud at Customer.
Both compute nodes are provisioned with the following operating system user accounts.
The system administrator account you use to connect to the compute node using SSH. This user can use the sudo command to perform operations that require root-user access.
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. Additionally, by default you cannot connect as this user to the compute node using SSH. You can add the public key to the user’s $HOME/.ssh/authorized_keys file to grant persistent SSH access, or you can connect as the opc user and then use the sudo -s command to start a root-user command shell, followed by an su — oracle command to switch to the oracle user.
The Oracle Grid Infrastructure administrator account you use to perform ASM, ACFS, and clusterware administration tasks. A home directory, /home/grid , is created for this user. This user cannot use the sudo command to perform operations that require root-user access. Additionally, by default you cannot connect as this user to the compute node using SSH. You can add the public key to the user’s $HOME/.ssh/authorized_keys file to grant persistent SSH access, or you can connect as the opc user and then use the sudo -s command to start a root-user command shell, followed by an su — grid command to switch to the grid user.
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 variable settings are created for the opc , oracle and grid users.
The home directory of the user, either /home/opc , /home/oracle or /home/grid .
The host name of the compute node:
deployment-name 1 for the first compute node
deployment-name 2 for the second compute node
The system language, en_US.UTF-8 .
The default shell, /bin/bash .
The user name, either opc , oracle or grid .
In addition, the PATH variable is also created for all three users, but its value differs (line breaks added to improve clarity):
For the opc user:
For the oracle user:
where db-version is 18.0.0 , 12.2.0.1 , 12.1.0.2 or 11.2.0.2 , depending on which version of Oracle Database was installed.
For the grid user:
In addition, the following environment variable settings are created for the oracle user.
The Oracle Database library directory:
For Oracle Database 18c, /u01/app/oracle/product/18.0.0/dbhome_1/lib
For Oracle Database 12c Release 2, /u01/app/oracle/product/12.2.0.1/dbhome_1/lib

The database system identifier (SID) for the database instance on the compute node:
db-sid 1 for the first compute node
db-sid 2 for the second compute node
where db-sid is the database system identifer (SID) provided as the DB Name (SID) value during the database deployment creation process.
The database system identifer (SID) provided as the DB Name (SID) value during the database deployment creation process.
In addition, the following environment variable settings are created for the grid user.
Set to /u01/app/12.1.0.2/grid/lib .
