ORA-12012 Auto Execute Error Tips

Expert Oracle Database Tips by Donald BurlesonFebruary 11, 2015


Question:  I am receiving the following error in my Alert log. But my job is not broken and there are no failures. Any idea what is going on and how I can resolve this?

ORA-12012: error on auto execute of job 62
ORA-12005: may not schedule automatic refresh for times in the past

Broken = N
Failure = 0
Interval = trunc(sysdate)+23/24
Last Date =10/21/2005 12:02:15 AM
Next Date =10/21/2005 11:00:00 PM
ORA-12012: error on auto execute of job 62
ORA-12005: may not schedule automatic refresh for times in the past

How do I find out the cause of this ORA-12012 error and the accompanying ORA-12005 error? 

Answer:  ORA-12012 error is a generic error and you need to look closer to find the real error code that indicates why the job failed. To diagnose any error, you start by using the oerr utility to display the ORA-12012 error:

ORA-12012: Error on Auto Execute of Job

Cause:  An error was caught while doing an automatic execution of a job.

Action: Look at the accompanying errors for details on why the execute failed.

As is indicated by the utility, the required action is to look at the accompanying errors for details on why the execute failed.  In this case, the accompanying error is:

ORA-12005: may not schedule automatic refresh for times in the past. 

This means that there's something wrong with the part of your code dealing with the automatic refresh, specifically the interval.  Your interval is set  as follows:

interval = trunc(sysdate)+23/24

The code you have written sets an interval where Oracle is trying to run the job at a time in the past, which it simply cannot do.  So, change your interval to this:

interval = trunc(sysdate+1)+23/24

And your Oracle job will run smooth as silk! 

An ORA-12012 error should come with an accompanying error that will basically tell you what you did wrong.  Fix that, and assuming there are no other problems, your job should run just fine.


The BC Oracle forum has more details on this ORA-12012 job execution error.

One problem with the ORA 12012 error is that you have the job number but not the job name.

 The following SQL will display the dbms_scheduler job name for any giver job number (passed as &myjobnum):

    dba_scheduler_jobs d,
    sys.scheduler$_job s
    d.job_action = s.program_action
    s.obj# = &myjobnum;
