Switch Users on a Node
After connecting to an Oracle Java Cloud Service node, you can change operating system (OS) users in order to perform specific administration tasks.
By default, you must connect to a node only as the opc
user. This user has root privileges on the OS running in the node. For example, opc
can be used to create other OS users on a node. Simply prefix root operations with the sudo
command. For example:
sudo useradd myuser
Note:
There is no default password for theopc
user.
Switch 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 node, or to run other Oracle applications and utilities on the node.
Type the following to become the oracle
user:
sudo su - oracle
Note:
There is no default password for theoracle
user.
Switch to the Root User
An alternative to using the sudo
command to perform root OS operations with the opc
user is to switch to the root
user.
Type the following to become the root
user:
sudo -s
Caution:
Avoid using theroot
user except to perform privileged OS administration tasks.
