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

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.

Execution logs:

3            from dba_scheduler_job_run_details a

I hope it help you too!

    HI,
    Thanks for stating the process to resolve this. We are facing the same issue in our Oracle 11.2.0.3 database running on AIX 7.1 server.

    Is there a chance this process will corrupt the database? I need to confirm before executing this. Kindly reply.

      Hello Debomitra,
      The best suggestion I can give is to open a SR and have this confirmation from Oracle.

      This is most likely not corrupt your database, but once done the stats will not be gathered for the database ID you deleted. So, make sure your are deleting the proper DBID/instance name.

      Anyway, I sguggest you store the information in a backup table before deleting. Something like a CTAS should be enough.

      Cheers!
