禁用sql tuning advisor功能

1.查看自动收集统计信息的任务及状态 sys@ora11g> select client_name,status from dba_autotask_client; CLIENT_NAME STATUS ------------------------------------- -------- auto optimizer stats collection ENABLED auto space advisor ENABLED tuning advisor ENABLED 其中“auto optimizer stats collection”便是我们要寻找的自动收集统计信息的任务名称，它的状态目前是启用状态。 2.禁止自动sql tuning advisor的任务 我们可以使用DBMS_AUTO_TASK_ADMIN包完成这个任务。 sys@ora11g> exec DBMS_AUTO_TASK_ADMIN.DISABLE(client_name => 'sql tuning advisor',operation => NULL,window_name => NULL); PL/SQL procedure successfully completed. sys@ora11g> select client_name,status from dba_autotask_client; CLIENT_NAME STATUS ------------------------------------- -------- auto optimizer stats collection ENABLED auto space advisor ENABLED sql tuning advisor DISABLED 此时“sql tuning advisor”任务已经被禁用，目的达到。 3.启用sql tuning advisor的任务 sys@ora11g> exec DBMS_AUTO_TASK_ADMIN.ENABLE(client_name => 'sql tuning advisor',operation => NULL,window_name => NULL); PL/SQL procedure successfully completed. sys@ora11g> select client_name,status from dba_autotask_client; CLIENT_NAME STATUS ------------------------------------- -------- auto optimizer stats collection ENABLED auto space advisor ENABLED sql tuning advisor ENABLED
