Oracle Database Vault provides schemas that contain Database Vault objects, roles that provide separation of duty for specific tasks, and default user accounts.
Topics:
The Oracle Database Vault schemas, DVSYS
and DVF
, support the administration and run-time processing of Oracle Database Vault.
The DVSYS
and DVF
contain the following:
DVSYS Schema: Owns the Oracle Database Vault schema and related objects
DVF Schema: Owns the Oracle Database Vault functions that are created to retrieve factor identities
The DVSYS
schema contains Oracle Database Vault database objects.
These objects store Oracle Database Vault configuration information and support the administration and run-time processing of Oracle Database Vault.
In a default installation, the DVSYS
schema is locked. The DVSYS
schema also owns the AUDIT_TRAIL$
table.
In a multitenant environment, the DVSYS
schema is considered a common schema, which means that the objects within DVSYS
(tables, views, PL/SQL packages, and so on) are automatically available to any child pluggable databases (PDBs). In addition, the DVSYS
schema account cannot switch to other containers using the ALTER SESSION
statement.
Oracle Database Vault secures the DVSYS
schema by using a protected schema design. A protected schema design guards the schema against improper use of system privileges (for example, SELECT ANY TABLE
, CREATE ANY VIEW
, or DROP ANY
).
Oracle Database Vault protects and secures the DVSYS
schema in the following ways:
The DVSYS
protected schema and its administrative roles cannot be dropped. By default, the DVSYS
account is locked.
By default, users cannot directly log into the DVSYS
account. To control the ability of users to directly log into this account, you can run the DBMS_MACADM.DISABLE_DV_DICTIONARY_ACCTS
procedure to prevent users from logging in and the DBMS_MACADM.ENABLE_DV_DICTIONARY_ACCTS
procedure to allow users to log in.
Statements such as CREATE USER
, ALTER USER
, DROP USER
, CREATE PROFILE
, ALTER PROFILE
, and DROP PROFILE
can only be issued by a user with the DV_ACCTMGR
role. A user logged in with the SYSDBA
administrative privilege can issue these statements only if it is allowed to do so by modifying the Can Maintain Accounts/Profiles rule set.
The powerful ANY
system privileges for database definition language (DDL) and data manipulation language (DML) commands are blocked in the protected schema. This means that the objects in the DVSYS
schema must be created by the schema account itself. Also, access to the schema objects must be authorized through object privilege grants.
Object privileges in the DVSYS
schema can only be granted to Database Vault administrative roles in the schema. This means that users can access the protected schema only through predefined administrative roles.
Only the protected schema account DVSYS
can issue ALTER ROLE
statements on Database Vault predefined administrative roles of the schema. Oracle Database Vault Roles describes Oracle Database Vault predefined administrative roles in detail.
The SYS.DBMS_SYS_SQL.PARSE_AS_USER
procedure cannot be used to run SQL statements on behalf of the protected schema DVSYS
.
Note:
Database users can grant additional object privileges and roles to the Oracle Database Vault administrative roles (DV_ADMIN
and DV_OWNER
, for example) provided they have sufficient privileges to do so.
The DVF
schema is the owner of the Oracle Database Vault DBMS_MACSEC_FUNCTION
PL/SQL package.
This package contains the functions that retrieve factor identities. After you install Oracle Database Vault, the installation process locks the DVF
account to better secure it. When you create a new factor, Oracle Database Vault creates a new retrieval function for the factor and saves it in this schema.
In a multitenant environment, the DVF
user cannot switch to other containers using the ALTER SESSION
statement.
By default, users cannot directly log into the DVF
account. To control the ability of users to directly log into this account, you can run the DBMS_MACADM.DISABLE_DV_DICTIONARY_ACCTS
procedure to prevent users from logging in and the DBMS_MACADM.ENABLE_DV_DICTIONARY_ACCTS
procedure to allow users to log in.
Oracle Database Vault provides default roles that are based on specific user tasks and adhere to separation of duty concepts.
Topics:
Oracle Database Vault provides a set of roles that are required for managing Oracle Database Vault.
Figure 12-1 illustrates how these roles are designed to implement the first level of separation of duties within the database. How you use these roles depends on the requirements that your company has in place.
Figure 12-1 How Oracle Database Vault Roles Are Categorized
Note:
You can grant additional object privileges and roles to the Oracle Database Vault roles to extend their scope of privileges. For example, a user logged in with the SYSDBA
administrative privilege can grant object privileges to an Oracle Database Vault role as long as the object is not in the DVSYS
schema or realm.
See Also:
Oracle Database Security Guide for general guidelines on managing roles
The Oracle Database Vault roles are designed to provide the maximum benefits of separation of duty.
The DV_PATCH_ADMIN
, DV_STREAMS_ADMIN
, DV_XSTREAM
, DV_GOLDENGATE_ADMIN
, and DV_GOLDENGATE_REDO_ACCESS
roles are not included in the following table because they have no system privileges.
Table 12-1 summarizes the privileges available with Oracle Database Vault roles.

The user with this role also must be the realm participant or owner to exercise his or her system privileges.
Footnote 11
The RESOURCE
role provides the following system privileges: CREATE CLUSTER
, CREATE INDEXTYPE
, CREATE OPERATOR
, CREATE PROCEDURE
, CREATE SEQUENCE
, CREATE TABLE
, CREATE TRIGGER
, CREATE TYPE
.
The DV_OWNER
role enables you to manage the Oracle Database Vault roles and its configuration.
In Oracle Database Vault Administrator's Guide, the example account that uses this role is leo_dvowner
.
Privileges Associated with the DV_OWNER Role
The DV_OWNER
role has the administrative capabilities that the DV_ADMIN
role provides, and the reporting capabilities the DV_SECANALYST
role provides.
This role also provides privileges for monitoring Oracle Database Vault. It is created when you install Oracle Database Vault, and has the most privileges on the DVSYS
schema. In addition to DV_ADMIN
role, the DV_OWNER
role has the GRANT ANY ROLE
, ADMINISTER DATABASE TRIGGER
, and ALTER ANY TRIGGER
privileges.
To find the full list of system and object privileges associated with the DV_OWNER
role, you can log into the database instance enter the following queries:
SELECT TABLE_NAME, OWNER, PRIVILEGE FROM DBA_TAB_PRIVS WHERE GRANTEE = 'DV_OWNER'; SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'DV_OWNER';
When you install and register Oracle Database Vault, the DV_OWNER
account is created. The user who is granted this role is also granted the ADMIN
option and can grant any Oracle Database Vault roles (except DV_ACCTMGR
) to any account. Users granted this role also can run Oracle Database Vault reports and monitor Oracle Database Vault.
Tip:
Oracle strongly recommends that you create separate, named account for the DV_OWNER
user. This way, if the user is no longer available (for example, he or she left the company), then you can easily recreate this user account and then grant this user the DV_OWNER
role.
How Are GRANT and REVOKE Operations Affected by DV_OWNER?
Anyone with the DV_OWNER
role can grant the DV_OWNER
and DV_ADMIN
roles to another user.
The account granted this role can revoke any granted Database Vault role from another account. Accounts such as SYS
or SYSTEM
, with the GRANT ANY ROLE
system privilege alone (directly granted or indirectly granted using a role) do not have the right to grant or revoke the DV_OWNER
role to or from any other database account. Note also that a user with the DV_OWNER
role cannot grant or revoke the DV_ACCTMGR
role.
Managing Password Changes for Users Who Have the DV_OWNER Role
Before you can change the password for another user who has been granted the DV_OWNER
role, you must revoke the DV_OWNER
role from that user account.
However, be cautious about revoking the DV_OWNER
role. At least one user on your site must have this role granted. If another DV_OWNER
user has been granted this role and needs to have his or her password changed, then you can temporarily revoke DV_OWNER
from that user. Note also that if you have been granted the DV_OWNER
role, then you can change your own password without having to revoke the role from yourself.
To change the DV_OWNER
user password:
Log into the database instance using an account that has been granted the DV_OWNER
role.
Revoke the DV_OWNER
role from the user account whose password needs to change.
Connect as a user who has been granted the DV_ACCTMGR
role and then change the password for this user.
Connect as the DV_OWNER
user and then grant the DV_OWNER
role back to the user whose password you changed.
DV_OWNER Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database Vault roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE
system privilege can perform GRANT
and REVOKE
operations on protected Database Vault roles.

Disabling and Enabling Oracle Database Vault, for information about disabling and enabling Oracle Database Vault
The DV_ADMIN
role controls the Oracle Database Vault PL/SQL packages.
These packages are the underlying interface for the Database Vault Administrator user interface in Oracle Enterprise Manager Cloud Control.
Privileges Associated with the DV_ADMIN Role
The DV_ADMIN
role has the EXECUTE
privilege on the DVSYS
packages (DBMS_MACADM
, DBMS_MACSECROLES
, and DBMS_MACUTL
).
DV_ADMIN
also has the capabilities provided by the DV_SECANALYST
role, which allow the user to run Oracle Database Vault reports and monitor Oracle Database Vault. During installation, the DV_ADMIN
role is granted to the DV_OWNER
role with the ADMIN OPTION
.
To find the full list of system and object privileges associated with the DV_ADMIN
role, log into the database instance with sufficient privileges and then enter the following queries:
SELECT TABLE_NAME, OWNER, PRIVILEGE FROM DBA_TAB_PRIVS WHERE GRANTEE = 'DV_ADMIN'; SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'DV_ADMIN';
How Are GRANT and REVOKE Operations Affected by DV_ADMIN?
Accounts such as SYS
or SYSTEM
, with the GRANT ANY ROLE
system privilege alone do not have the rights to grant or revoke DV_ADMIN
from any other database account.
The user with the DV_OWNER
role can grant or revoke this role to and from any database account.
Managing Password Changes for Users Who Have the DV_ADMIN Role
Before you can change the password for a user who has been granted the DV_ADMIN
role, you must revoke the DV_ADMIN
role from this account.
If you have been granted the DV_ADMIN
role, then you can change your own password without having to revoke the role from yourself.
To change the DV_ADMIN
user password:
Log into the database instance using an account that has been granted the DV_OWNER
role.
Revoke the DV_ADMIN
role from the user account whose password needs to change.
Connect as a user who has been granted the DV_ACCTMGR
role and then change the password for this user.
Connect as the DV_OWNER
user and then grant the DV_ADMIN
role back to the user whose password you changed.
DV_ADMIN Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database Vault roles is enforced only if Oracle Database Vault is enabled.

There are no system privileges associated with the DV_MONITOR
role, but it does have the SELECT
privilege on SYS
and DVSYS
objects.
To find the full list of DV_MONITOR
object privileges, log into the database instance with sufficient (such as DV_OWNER
) privileges and then enter the following query:
SELECT TABLE_NAME, OWNER, PRIVILEGE FROM DBA_TAB_PRIVS WHERE GRANTEE = 'DV_MONITOR';
How Are GRANT and REVOKE Operations Affected by DV_MONITOR?
By default, the DV_MONITOR
role is granted to the DV_OWNER
role and the DBSNMP
user.
Only a user who has been granted the DV_OWNER
role can grant or revoke the DV_MONITOR
role to another user.
DV_MONITOR Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database Vault roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE

role, but it does have the SELECT
privilege for some DVSYS
schema objects and portions of the SYS
and SYSMAN
schema objects for reporting on DVSYS
- and DVF
-related entities.
To find the full list of DV_SECANALYST
object privileges, log into the database instance with sufficient privileges and then enter the following query:
SELECT TABLE_NAME, OWNER, PRIVILEGE FROM DBA_TAB_PRIVS WHERE GRANTEE = 'DV_SECANALYST';
How Are GRANT and REVOKE Operations Affected by DV_SECANALYST?
Any account, such as SYS
or SYSTEM
, with the GRANT ANY ROLE
system privilege alone does not have the rights to grant this role to or revoke this role from any other database account.

The DV_PATCH_ADMIN
role is used for patching operations.
In order to generate all Database Vault-related audit records in accordance with the audit policies specified in the Database Vault metadata as well as Database Vault unified audit policies, execute the DBMS_MACADM.ENABLE_DV_PATCH_ADMIN_AUDIT
procedure as a user who has been granted the DV_ADMIN
role before using the DV_PATCH_ADMIN
role.
Temporarily grant the DV_PATCH_ADMIN
role to any database administrator who is responsible for performing database patching. Before this administrator performs the patch operation, run the DBMS_MACADM.ENABLE_DV_PATCH_ADMIN_AUDIT
procedure. This procedure enables realm, command rule, and rule set auditing of the actions by users who have been granted the DV_PATCH_ADMIN
role, in accordance with the existing audit configuration. If you have mixed-mode auditing, then this user's actions are written to the AUDIT_TRAIL$
table. If you have pure unified auditing enabled, then you should create a unified audit policy to capture this user's actions.
After the patch operation is complete, do not immediately disable the auditing of users who are responsible for performing database patch operations. This way, you can track the actions of the DV_PATCH_ADMIN
role users. For backwards compatibility, this type of auditing is disabled by default.
Privileges Associated with the DV_PATCH_ADMIN Role
The DV_PATCH_ADMIN
role does not provide access to any secured data.
The DV_PATCH_ADMIN
role a special Database Vault role that does not have any object or system privilege. It is designed to allow the database administrator or the user SYS
to patch Database Vault enabled databases (for example, applying a database patch without disabling Database Vault). It also enables the database administrator to create users, because some patches may require the need to create new schemas.
How Are GRANT and REVOKE Operations Affected by DV_PATCH_ADMIN?
Only a user who has the DV_OWNER
role can grant or revoke the DV_PATCH_ADMIN
role to and from another user.
DV_PATCH_ADMIN Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE
system privilege can perform GRANT
and REVOKE
operations on protected Database Vault roles.
See Also:
Oracle Database Security Guide for information about creating unified audit policies
The DV_ACCTMGR
role is a powerful role, used for accounts management.
Note:
This feature has been updated in Oracle Database 12c Release 1 (12.1.0.2).
Use the DV_ACCTMGR
role to create and maintain database accounts and database profiles. In this manual, the example DV_ACCTMGR
role is assigned to a user named bea_dvacctmgr
.
Privileges Associated with the DV_ACCTMGR Role
A user who has been granted this role can use the CREATE
, ALTER
, and DROP
statements for user accounts or profiles, including users who have been granted the DV_SECANALYST
, DV_AUDIT_CLEANUP
, and DV_MONITOR
roles.
This user also can grant the CREATE SESSION
privilege to other users. However, a person who has been granted the DV_ACCTMGR
role cannot perform the following operations:
ALTER
or DROP
statements on the DVSYS
account
ALTER
or DROP
statements on users who have been granted the DV_ADMIN
or DV_OWNER
role
Change passwords for users who have been granted the DV_ADMIN
or DV_OWNER
role
To find the full list of system and object privileges associated with the DV_ACCTMGR
role, log into the database instance with sufficient privileges and then enter the following queries:
SELECT TABLE_NAME, OWNER, PRIVILEGE FROM DBA_TAB_PRIVS WHERE GRANTEE = 'DV_ACCTMGR'; SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'DV_ACCTMGR';
Tips:
If you want the DV_ACCTMGR
user to be able to grant or revoke the ANY
privileges for other users, then log in as user SYS
with the SYSDBA
privilege and grant this user the GRANT ANY PRIVILEGE
and REVOKE ANY PRIVILEGE
privileges. Then add this user to the Oracle System Privilege and Role Management Realm as an owner.
Consider creating a separate, named account for the DV_ACCTMGR
user. This way, if this user forgets his or her password, you can log in as the original DV_ACCTMGR
account and reset the user's password. Otherwise, you must disable Oracle Database Vault, log in as SYS
or SYSTEM
to recreate the password, and then re-enable Database Vault.
How Are GRANT and REVOKE Operations Affected by DV_ACCTMGR?
Any account, such as SYS
or SYSTEM
, with the GRANT ANY ROLE
system privilege alone does not have the rights to grant this role to or revoke this role from any other database account.
The account with the DV_ACCTMGR
role and the ADMIN OPTION
can grant this role to any given database account and revoke this role from another account.
DV_ACCTMGR Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE
system privilege can perform GRANT
and REVOKE
operations on protected Database Vault roles.

The DV_REALM_OWNER
role is used for realm management.
Use the DV_REALM_OWNER
role to manage database objects in multiple schemas that define a realm.
Grant this role to the database account who is responsible for managing one or more schema database accounts within a realm and the roles associated with the realm.
Privileges Associated with the DV_REALM_OWNER Role
A user who has been granted this role can use powerful system privileges like CREATE ANY
, ALTER ANY
, and DROP ANY
within the realm.
However, before this user can exercise these privileges, you must make this user either a participant or an owner for the realm. See About Realm Authorization for instructions.
There are no object privileges granted to the DV_REALM_OWNER
role, but it does have some system privileges. To find the full list of DV_REALM_OWNER
system privileges, log into the database instance with sufficient privileges and enter the following query:
SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'DV_REALM_OWNER';
How Are GRANT and REVOKE Operations Affected by DV_REALM_OWNER?
The realm owner of the Oracle System Privilege and Role Management realm, such as SYS
, can grant this role to any given database account or role.
Note that though this role has powerful system privileges, it does not have any Oracle Database Vault roles such as the DV_OWNER
or DV_ADMIN
roles.
If you want to attach this role to a specific realm, then you must assign it to an account or business-related role, then authorize that account or role in the realm.
DV_REALM_OWNER Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE
system privilege can perform GRANT
and REVOKE
operations on protected Database Vault roles.

The DV_REALM_RESOURCE
role is use for the management of realm resources.
Use the DV_REALM_RESOURCE
role for operations such as creating tables, views, triggers, synonyms, and other objects that a realm would typically use.
Privileges Associated with the DV_REALM_RESOURCE Role
The DV_REALM_RESOURCE
role provides the same system privileges as the Oracle RESOURCE
role. In addition, both CREATE SYNONYM
and CREATE VIEW
are granted to this role.
There are no object privileges granted to the DV_REALM_RESOURCE
role, but it does have some system privileges. To find the full list of DV_REALM_RESOURCE
system privileges, log into the database instance with sufficient privileges and enter the following query:
SELECT PRIVILEGE FROM DBA_SYS_PRIVS WHERE GRANTEE = 'DV_REALM_RESOURCE';
Though this role has powerful system privileges, it does not have any Oracle Database Vault roles such as the DV_OWNER
or DV_ADMIN
roles.
How Are GRANT and REVOKE Operations Affected by DV_REALM_RESOURCE?
You can grant the DV_REALM_RESOURCE
role to a database account that owns database tables, objects, triggers, views, procedures, and so on that are used to support any database application.
This is a role designed for a schema type database account. The realm owner of the Oracle System Privilege and Role Management realm, such as SYS
, can grant this role to any database account or role.
DV_REALM_RESOURCE Status When Oracle Database Vault Security Is Disabled
The protection of all Oracle Database roles is enforced only if Oracle Database Vault is enabled.
If Oracle Database Vault is disabled, then any account with the GRANT ANY ROLE
system privilege can perform GRANT
and REVOKE
operations on protected Database Vault roles.

You must create accounts for the Oracle Database Vault Owner and Oracle Database Vault Account Manager during the registration process.
You must supply an account name and password for the Oracle Database Vault Owner accounts during installation. Creating an Oracle Database Vault Account Manager is optional but strongly recommended for better separation of duty.
The Oracle Database Vault Owner account is granted the DV_OWNER
role. This account can manage Oracle Database Vault roles and configuration. (See DV_OWNER Database Vault Owner Role for detailed information about this role.)
The Oracle Database Vault Account Manager account is granted the DV_ACCTMGR
role. This account is used to manage database user accounts to facilitate separation of duties. (See DV_ACCTMGR Database Vault Account Manager Role for detailed information about this role.)
If you choose not to create the Oracle Database Vault Account Manager account during installation, then both the DV_OWNER
and DV_ACCTMGR
roles are granted to the Oracle Database Vault Owner user account.
Table 12-2 lists the Oracle Database Vault database accounts that are needed in addition to the accounts that you create during installation.
Table 12-2 Database Accounts Used by Oracle Database Vault
Database Account | Roles and Privileges | Description |
---|---|---|
|
Several system and object privileges are provided to support Oracle Database Vault. The ability to create a session with this account is revoked at the end of the installation, and the account is locked. |
Owner of Oracle Database Vault schema and related objects |
|
A limited set of system privileges are provided to support Oracle Database Vault. The ability to create a session with this account is revoked at the end of the installation, and the account is locked. |
Owner of the Oracle Database Vault functions that are created to retrieve factor identities |
|
This account is created when you install Oracle Label Security by using the Oracle Universal Installer custom installation option. (It is not created when you install Oracle Database Vault.) Do not drop or re-create this account. If you plan to integrate a factor with an Oracle Label Security policy, you must assign this user as the owner of the realm that uses this factor. See Using Oracle Database Vault Factors with Oracle Label Security Policies for more information. |
Owner of the Oracle Label Security schema |
You can create different database accounts to implement the separation of duties requirements for Oracle Database Vault. Table 12-3 lists some model database accounts that can act as a guide. (The accounts listed in Table 12-3 serve as a guide to implementing Oracle Database Vault roles. These are not actual accounts that are created during installation.)
Table 12-3 Model Oracle Database Vault Database Accounts
Database Account | Roles and Privileges | Description |
---|---|---|
|
|
Account that is the realm owner for the Oracle Database Vault realm. This account can:
|
|
|
Account for administration of database accounts and profiles. This account can:
Note: This account cannot create roles, or grant the |
|
|
Account to serve as the access control administrator. This account can:
Note: This account cannot directly update the |
|
|
Account for running Oracle Database Vault reports |

Backup Oracle Database Vault Accounts for information about the importance of maintaining backup accounts for the DV_OWNER
and DV_ACCTMGR
accounts
As a best practice, you should maintain backup accounts for the DV_OWNER
and DV_ACCTMGR
roles.
The Oracle Database Vault registration process entails creating both day-to-day and backup accounts for the DV_OWNER
and DV_ACCTMGR
roles. You should keep and maintain these accounts as a safety measure in case a user who has been granted one of these roles forgets his or her password or leaves the organization. Then you can log in to the backup account to recover the password or grant the role to a new account. These should be only used as a backup account kept safe in a privileged account management system or an organization break-glass (or emergency password recovery) system.
Because of the strong separation of duty that Oracle Database Vault implements, loss of access to the DV_OWNER
account will force you to rebuild the database. The SYS
account cannot override the DV_OWNER
account
