Metalink doc

ORA-12012 Error on auto execute of job "SYS"."ORA$AT_OS_OPT_SY_<NN> in 12.2 Database (Doc ID 2127675.1)

$ sqlplus / as sysdba

 EXEC dbms_stats.init_package();

column name format A35
set linesize 120

select name, ctime, how_created
  from sys.wri$_adv_tasks
 where owner_name = 'SYS'
   and name in ('AUTO_STATS_ADVISOR_TASK','INDIVIDUAL_STATS_ADVISOR_TASK');

Output of the query will look like this:

NAME                                 CTIME      HOW_CREATED
----------------------------------- ---------- ------------------------------
AUTO_STATS_ADVISOR_TASK              14-APR-16 CMD
INDIVIDUAL_STATS_ADVISOR_TASK        14-APR-16 CMD

Workaround

執行後執行上述的sql後, 應已生效

NAME                                CTIME               HOW_CREATED
----------------------------------- ------------------- ------------------------------
AUTO_STATS_ADVISOR_TASK             2018-06-04 09:39:34 CMD
INDIVIDUAL_STATS_ADVISOR_TASK       2018-06-04 09:39:34 CMD

另外再查詢 alert log, 也沒再出現

$ awk '
/ORA-12012/ {
        for (i = (b + 1) % 3; i != b; i = (i + 1) % 3) {
                print before[i]
        }
        print (NR "-" ($0))
        a = 1
}

a-- > 0 {
        print (" ")
}

{
        before[b] = (NR ":" ($0))
        b = (b + 1) % 3
}' $ALERT
