参照MOS文档：
ORA-12012 Error on auto execute of job “SYS”."ORA$AT_OS_OPT_SY_ in 12.2.0 Database version or higher release (like 18c) (Doc ID 2127675.1)

解决方法：

SQL> EXEC dbms_stats.init_package();
 
PL/SQL procedure successfully completed.
 
SQL> column name format A35
SQL> set linesize 120
SQL>
SQL> select name, ctime, how_created
2 from sys.wri$_adv_tasks
3 where owner_name = 'SYS'
4 and name in ('AUTO_STATS_ADVISOR_TASK','INDIVIDUAL_STATS_ADVISOR_TASK');
 
NAME CTIME
----------------------------------- -------------------
HOW_CREATED
------------------------------------------------------------------------------------------
AUTO_STATS_ADVISOR_TASK 2021-05-03 13:29:01
CMD
 
INDIVIDUAL_STATS_ADVISOR_TASK 2021-05-03 13:29:01
CMD

若此方法不行，参照MOS文档中另外的解决方法：

$ sqlplus / as sysdba
 
select name, ctime, how_created,OWNER_NAME from sys.wri$_adv_tasks
where name in ('AUTO_STATS_ADVISOR_TASK','INDIVIDUAL_STATS_ADVISOR_TASK');
 
  
 
If the OWNER is a non-SYS user, you have to drop the tasks as that user first and then try to solution mention in the Note again.
 
This was a case for one customer.
 
For example:
 
--- Connect as SYSTEM, for example, if that user owned the tasks and non SYS for some reason
 
SQL> conn system/&password
 
 
DECLARE
v_tname VARCHAR2(32767);
BEGIN
v_tname := 'AUTO_STATS_ADVISOR_TASK';
DBMS_STATS.DROP_ADVISOR_TASK(v_tname);
END;
/
 
SQL> DECLARE
v_tname VARCHAR2(32767);
BEGIN
v_tname := 'INDIVIDUAL_STATS_ADVISOR_TASK';
DBMS_STATS.DROP_ADVISOR_TASK(v_tname);
END;
/
 
 
connect / as sysdba
EXEC DBMS_STATS.INIT_PACKAGE();
