Change VM Users
You can change users on a VM in order to perform specific administration tasks.
You must SSH to a VM only as the opc
user. This user has root
privileges on the operating system (OS) running in the VM. For example,
opc
can be used to create other OS users on a VM. Simply prefix
root operations with the sudo
command. For example:
sudo useradd myuser
Note:
There is no default password for theopc
user.
Changing to the oracle
user
The oracle
user has regular OS user permissions. It is intended to
be used to start and stop Oracle products that have been installed on the VM, or to
run other Oracle applications and utilities on the VM.
To change to the oracle
user, enter the following command:
sudo su - oracle
Note:
There is no default password for theoracle
user.
Changing to the root
user
An alternative to using the sudo
command to perform root OS
operations as the opc
user is to change to the
root
user.
To change to the root
user, enter the following
command:
sudo -s
Note:
Avoid using theroot
user except to perform privileged OS administration tasks.
