It is highly recommended to run the WebLogic Server as a limited user process. The root user account in Unix/Linux and the Administrator account in Windows should not be used to run WebLogic Server since they are privileged user accounts. Other privileged accounts should also not be used to run the WebLogic server.

Hence, it is preferable to create a limited user account say WebLogic Owner for running the application server. Additional user accounts are not recommended; in the eventuality, that an additional account is required (say, if the WebLogic owner account is locked out), one of the system administrator accounts can be used to remedy the situation. Having two system administrator accounts is recommended, as it always ensures backup.
