11g中如何禁用自动统计信息收集作业

11g中如何禁用自动统计信息收集作业？

因为11g中auto stats gather job被集成到auto task中，所以与10g中的禁用方式不一样：

SQL> select client_name,status from DBA_AUTOTASK_CLIENT;

CLIENT_NAME                                                      STATUS
---------------------------------------------------------------- --------
auto optimizer stats collection                                  ENABLED
auto space advisor                                               ENABLED
sql tuning advisor                                               ENABLED

begin
DBMS_AUTO_TASK_ADMIN.DISABLE(client_name => 'auto optimizer stats collection',
operation => NULL,
window_name => NULL);
end;
/
PL/SQL procedure successfully completed.

SQL>  select client_name,status from DBA_AUTOTASK_CLIENT;
