Oracle Database Vault provides powerful security controls to help protect application data from unauthorized access, and to implement separation of duties between administrators and data owners to comply with privacy and regulatory requirements.

By default the ADMIN user has the DV_OWNER and DV_ACCTMGR roles. If you want to set up separate users for DV_OWNER and DV_ACCTMGR accounts. See Oracle Database Vault Schemas, Roles, and Accounts for more information.

The user management is by default enabled for the APEX component when Oracle Database Vault is enabled. When user management is enabled, the APEX users who have the necessary roles to CREATE | ALTER | DROP users have the needed privileges to perform these operations when Database Vault is enabled. To change this, see Disable User Management with Oracle Database Vault on Autonomous Database.

On Autonomous Database with Oracle Database Vault enabled, grant the following privileges:

• When using Oracle GoldenGate, grant the GGADMIN user DV_GOLDENGATE_ADMIN and DV_GOLDENGATE_REDO_ACCESS.

• The ADMIN user must grant the BECOME USER privilege to users who need to use Oracle Data Pump. To perform some Oracle Data Pump operations additional Oracle Database Vault authorization may be needed. For example to run a full database export or to export a realm protected schema requires using DBMS_MACADM.AUTHORIZE_DATAPUMP_USER.

  See AUTHORIZE_DATAPUMP_USER Procedure for more information.

• In order for DBMS_CLOUD credential related APIs to work when Oracle Database Vault is enabled and the credential owner's schema is protected using a Database Vault realm, you must add authorizations for the C##CLOUD$SERVICE user to the Database Vault realm.

  For example:

  BEGIN
      DBMS_MACADM.ADD_AUTH_TO_REALM(realm_name   => 'PROTECT_ADMIN',
          grantee       => 'C##CLOUD$SERVICE',
          rule_set_name => 'Enabled',
          auth_options  => DBMS_MACUTL.G_REALM_AUTH_PARTICIPANT);
  END;
  /

  Where PROTECT_ADMIN is your Oracle Database Vault realm.

  See ADD_AUTH_TO_REALM Procedure for more information.

Shows the steps to enable Oracle Database Vault on Autonomous Database.

1. Configure Oracle Database Vault using the following command:

   EXEC DBMS_CLOUD_MACADM.CONFIGURE_DATABASE_VAULT('adb_dbv_owner', 'adb_dbv_acctmgr');

   Where:

   • adb_dbv_owner is the Oracle Database Vault owner.
   • adb_dbv_acctmgr is the account manager.

   See CONFIGURE_DATABASE_VAULT Procedure for more information.

2. Enable Oracle Database Vault:

   EXEC DBMS_CLOUD_MACADM.ENABLE_DATABASE_VAULT;

   See ENABLE_DATABASE_VAULT Procedure for more information.

3. Restart the Autonomous Database instance.

   See Restart Autonomous Database for more information.

SELECT * FROM DBA_DV_STATUS;

NAME                 STATUS
-------------------- -----------
DV_CONFIGURE_STATUS  TRUE
DV_ENABLE_STATUS     TRUE

Shows the steps to disable Oracle Database Vault on Autonomous Database.

1. Disable Oracle Database Vault.

   EXEC DBMS_CLOUD_MACADM.DISABLE_DATABASE_VAULT;

   See DISABLE_DATABASE_VAULT Procedure for more information.

2. Restart the Autonomous Database instance.

   See Restart Autonomous Database for more information.

SELECT * FROM DBA_DV_STATUS;

NAME                 STATUS
-------------------- -----------
DV_CONFIGURE_STATUS  TRUE
DV_ENABLE_STATUS     FALSE

Shows how to disallow user management related operations for specified components on Autonomous Database with Oracle Database Vault enabled.

1. As a user granted DV_ACCTMGR and DV_ADMIN roles you can disable user management for specified components.
2. To disable user management for a specified component, for example for the APEX component, use the following command:

   EXEC DBMS_CLOUD_MACADM.DISABLE_USERMGMT_DATABASE_VAULT('APEX');

Shows the steps to allow user management for a specified component on Autonomous Database with Oracle Database Vault enabled.

1. A user granted DV_ACCTMGR and DV_ADMIN roles can enable user management for specified components.
2. To enable user management for a specified component, for example for the APEX component, use the following command:

   EXEC DBMS_CLOUD_MACADM.ENABLE_USERMGMT_DATABASE_VAULT('APEX');
