解决方案：

禁用sql tuning advisor

禁用后，第二天查看，已经不在出现ORA-00600: [qksdsInitSample:2]错误了；

SQL> select * from dba_autotask_client;

SQL>

BEGIN

  dbms_auto_task_admin.disable(client_name => 'sql tuning advisor',

                               operation   => NULL,

                               window_name => NULL);

END;

 

SQL> select * from dba_autotask_client;
