# OS_ROLES

Property | Description
--- | ---
Parameter type | Boolean
Default value | `false`
Modifiable | No
Range of values | `true | false`

`OS_ROLES` determines whether Oracle or the operating system identifies and manages the roles of each username.

Values:

- `TRUE`

  The operating system completely manages the role grants for all database usernames. When a user attempts to create a session, the username's security domain is initialized using the roles identified by the operating system. A user can subsequently enable as many roles identified by the operating system as specified by the parameter `MAX_ENABLED_ROLES`.

  Revocation by Oracle of roles granted by the operating system is ignored, as are any roles previously granted by Oracle.

- `FALSE`

  Oracle identifies and manages the roles.
