Ora 12012 ошибка при автоисполнение задания

Hi all,
Evaluating a database I detected it was failing to execute the default scheduler job SYS.BSLN_MAINTAIN_STATS_JOB. This job is an Oracle defined automatic moving window baseline statistics computation job, that runs only in weekends.
Below the last stack error in the alert log:

2016-04-24 00:00:10.064000 +00:00

According the notes below, the recommended action is to recreate the DBSNMP component:
Bug 10110625 – DBSNMP.BSLN_INTERNAL reports ORA-6502 running BSLN_MAINTAIN_STATS_JOB (Doc ID 10110625.8)
ORA-12012: Error on Auto Execute of job SYS.BSLN_MAINTAIN_STATS_JOB (Doc ID 1413756.1)
KEWBMBTA: Maintain BSLN Thresholds Failed, Check For Details. (Doc ID 1490391.1)

However, it’s a process that can affect other mechanisms. So, I found the follow note with the same error pointing to a privilege issue:
Ora-06508: Pl/Sql: Could Not Find Program Unit Being Called: “DBSNMP.BSLN_INTERNAL” (Doc ID 1323597.1)

But after granting the privilege as workaround suggested, the fail remais…

After that, while I was quering on DBSNMP, I realized another instance name active in DBSNMP.BSLN_BASELINES.
I guess this database was created with another instance name and then renamed without DBNID.

MYDB> select * from DBSNMP.BSLN_BASELINES;
DBID INSTANCE_NAME    BASELINE_ID BSLN_GUID                        TI A STATUS
---------- ---------------- ----------- -------------------------------- -- - ---------
4092499541 MYDB                       0 75B49690F8B4742084990643EEFFB6AA HX Y ACTIVE
4092499541 oldname                    0 415373CD9959B77AAEE1804F06D88B60 NW Y ACTIVE

So, I deleted the row and the job started to run successfully:

MYDB> DELETE FROM DBSNMP.BSLN_BASELINES WHERE INSTANCE_NAME ='oldname';
1 row deleted.
MYDB> commit;
Commit complete.
SQL> EXEC DBMS_SCHEDULER.RUN_JOB('BSLN_MAINTAIN_STATS_JOB');
PL/SQL procedure successfully completed.

I hope it help you too!

In alert log we are getting the error, So we checked the job number which is causing the error. If it is not needed then drop it or disable it by dbms_scheduler procedure.

For checking the status of job when its last run and owner and inform to application team if its belong to application job:

select
d.job_name,
d.job_action,d.NEXT_RUN_DATE,d.OWNER
from
dba_scheduler_jobs d,
sys.scheduler$_job s
where
d.job_action = s.program_action
and
s.obj# = 55536


If error related to Auto Gather stats jobs:
ORA-12012: error on auto execute of job "SYS"."ORA$AT_OS_OPT_SY_nn"

Error:

ORA-12012: error on auto execute of job “SYS”.”ORA$AT_OS_OPT_SY_”

Solution
1. Run the following query for checking advisory package:

col name for a30
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');

No rows selected

2. If no row found then initialize the package with following commands.

EXEC dbms_stats.init_package();

3. Verify the package create. It will fixed the issue.

col name for a30
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');

NAME                           CTIME     HOW_CREATED
