Oracle Database Appliance configuration creates operating system groups and users whose members are granted system administration privileges on the appliance.
During configuration, two administrative accounts are created for Oracle Database Appliance: the user grid, with a user ID (UID) of 1000, and the user oracle, with a UID of 1001. The user grid is the Oracle Grid Infrastructure installation owner. The user oracle is the Oracle Database installation owner, and the owner of all Oracle Database homes (Oracle homes). By default, these users are members of operating system groups whose members are granted privileges to start up and administer Oracle Database and Oracle Automatic Storage Management.
The following table describes the Oracle system privileges groups, and information about the operating system authentication groups:

If you create an initial database during deployment, then the password for the SYS and SYSTEM users is welcome1. Change this password for both users as soon as possible after configuration to prevent unauthorized access to your database using these privileged accounts.
