Change consumer group

Question

Hi,
in 10g R2 on Win 2003 server
I try to change the consumer group of user SCOTT :
SQL> SELECT NAME from V$RSRC_CONSUMER_GROUP;
NAME
SYS_GROUP
OTHER_GROUPS
LOW_GROUP
SQL> SELECT USERNAME,RESOURCE_CONSUMER_GROUP FROM V$SESSION where username='SCOTT';
USERNAME                       RESOURCE_CONSUMER_GROUP
SCOTT                          OTHER_GROUPS
SQL> EXEC DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_USER ('scott', 'LOW_GROUP');
PL/SQL procedure successfully completed.But does not work :
SQL> SELECT USERNAME,RESOURCE_CONSUMER_GROUP FROM V$SESSION where username='SCOTT';
USERNAME                       RESOURCE_CONSUMER_GROUP
SCOTT                          OTHER_GROUPSWhat is wrong in my action ?
Many thanks.

Answer 1

Thank SKU,
SQL> SELECT * FROM DBA_RSRC_CONSUMER_GROUP_PRIVS;
GRANTEE                        GRANTED_GROUP                  GRA INI
PUBLIC                         DEFAULT_CONSUMER_GROUP         YES YES
SYSTEM                         SYS_GROUP                      NO  YES
PUBLIC                         LOW_GROUP                      NO  NONo he is not.
What to do first then ?
Finally we should do like this :
SQL> SELECT USERNAME,RESOURCE_CONSUMER_GROUP FROM V$SESSION where username='SCOTT';
USERNAME                       RESOURCE_CONSUMER_GROUP
SCOTT                          OTHER_GROUPS
SQL> EXEC DBMS_RESOURCE_MANAGER.CREATE_PENDING_AREA;
PL/SQL procedure successfully completed.
SQL> EXEC DBMS_RESOURCE_MANAGER.SWITCH_CONSUMER_GROUP_FOR_USER ('SCOTT', 'LOW_GROUP');
PL/SQL procedure successfully completed.
SQL> EXEC DBMS_RESOURCE_MANAGER.SUBMIT_PENDING_AREA;
PL/SQL procedure successfully completed.
SQL> EXEC DBMS_RESOURCE_MANAGER.CLEAR_PENDING_AREA;
PL/SQL procedure successfully completed.
SQL> SELECT USERNAME,RESOURCE_CONSUMER_GROUP FROM V$SESSION where username='SCOTT';
USERNAME                       RESOURCE_CONSUMER_GROUP
SCOTT                          LOW_GROUP
