159.1.1 GRANT_SWITCH_CONSUMER_GROUP Procedure
This procedure grants the privilege to switch to a resource consumer group.
Syntax
DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP ( grantee_name IN VARCHAR2, consumer_group IN VARCHAR2, grant_option IN BOOLEAN);
Parameters
Table 159-2 GRANT_SWITCH_CONSUMER_GROUP Procedure Parameters
Parameter | Description |
---|---|
|
Name of the user or role to whom privilege is to be granted. |
|
Name of consumer group. |
|
|
Usage Notes
If you grant permission to switch to a particular consumer group to a user, then that user can immediately switch their current consumer group to the new consumer group.
If you grant permission to switch to a particular consumer group to a role, then any users who have been granted that role and have enabled that role can immediately switch their current consumer group to the new consumer group.
If you grant permission to switch to a particular consumer group to PUBLIC
, then any user can switch to that consumer group.
If the grant_option
parameter is TRUE
, then users granted switch privilege for the consumer group may also grant switch privileges for that consumer group to others.
In order to set the initial consumer group of a user, you must grant the switch privilege for that group to the user.

Examples
BEGIN DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP ( 'scott', 'mail_maintenance_group', true); DBMS_RESOURCE_MANAGER.CREATE_PENDING_AREA(); DBMS_RESOURCE_MANAGER.set_consumer_group_mapping( dbms_resource_manager.oracle_user, 'scott','mail_maintenance_group'); DBMS_RESOURCE_MANAGER.SUBMIT_PENDING_AREA(); END; /
159.1.2 GRANT_SYSTEM_PRIVILEGE Procedure
This procedure performs a grant of a system privilege to a user or role.
Syntax
DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SYSTEM_PRIVILEGE ( grantee_name IN VARCHAR2, privilege_name IN VARCHAR2 DEFAULT 'ADMINISTER_RESOURCE_MANAGER', admin_option IN BOOLEAN);
Parameters
Table 159-3 GRANT_SYSTEM_PRIVILEGE Procedure Parameters
Parameter | Description |
---|---|
|
Name of the user or role to whom privilege is to be granted. |
|
Name of the privilege to be granted. |
|
|
Usage Notes
Currently, Oracle provides only one system privilege for the Resource Manager: ADMINISTER_RESOURCE_MANAGER
. Database administrators have this system privilege with the ADMIN
option. The grantee and the revokee can either be a user or a role. Users that have been granted the system privilege with the ADMIN
option can also grant this privilege to others.
Examples
The following call grants this privilege to a user called scott
without the ADMIN
option:
BEGIN DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SYSTEM_PRIVILEGE ( grantee_name => 'scott', privilege_name => 'ADMINISTER_RESOURCE_MANAGER', admin_option => FALSE); END; /
159.1.3 REVOKE_SWITCH_CONSUMER_GROUP Procedure
This procedure revokes the privilege to switch to a resource consumer group.
Syntax
DBMS_RESOURCE_MANAGER_PRIVS.REVOKE_SWITCH_CONSUMER_GROUP ( revokee_name IN VARCHAR2, consumer_group IN VARCHAR2);
Parameters
Table 159-4 REVOKE_SWITCH_CONSUMER_GROUP Procedure Parameter
Parameter | Description |
---|---|
|
Name of user/role from which to revoke access. |
|
Name of consumer group. |
Usage Notes
If you revoke a user's switch privilege for a particular consumer group, then any subsequent attempts by that user to switch to that consumer group will fail.
If you revoke the initial consumer group from a user, then that user will automatically be part of the DEFAULT_CONSUMER_GROUP
consumer group when logging in.
If you revoke the switch privilege for a consumer group from a role, then any users who only had switch privilege for the consumer group through that role will not be able to switch to that consumer group.
If you revoke the switch privilege for a consumer group from PUBLIC
, then any users who could previously only use the consumer group through PUBLIC
will not be able to switch to that consumer group.
Examples
The following example revokes the privileges to switch to mail_maintenance_group
from Scott:
BEGIN DBMS_RESOURCE_MANAGER_PRIVS.REVOKE_SWITCH_CONSUMER_GROUP ( 'scott', 'mail_maintenance_group'); END; /
159.1.4 REVOKE_SYSTEM_PRIVILEGE Procedure
This procedure performs a revoke of a system privilege from a user or role.
Syntax
DBMS_RESOURCE_MANAGER_PRIVS.REVOKE_SYSTEM_PRIVILEGE ( revokee_name IN VARCHAR2, privilege_name IN VARCHAR2 DEFAULT 'ADMINISTER_RESOURCE_MANAGER');
Parameters
Table 159-5 REVOKE_SYSTEM_PRIVILEGE Procedure Parameters
Parameter | Description |
---|---|
|
Name of the user or role from whom privilege is to be revoked. |
|
Name of the privilege to be revoked. |

from user scott:
BEGIN DBMS_RESOURCE_MANAGER_PRIVS.REVOKE_SYSTEM_PRIVILEGE ('scott'); END; /
