How can I locate a Scheduler job?

Question

Hi there,
In the alert log, I see the following error :
ORA-12012: error on auto execute of job 2915
My question is - how do I find the definition for job 2915?
And before you say - "that's easy, it's in all_scheduler_jobs", it's
not in all_scheduler_jobs. The old dbms_job package had a column for
job number, but the Scheduler doesn't. I've scrutinized the definition for
all the Scheduler views, but nothing reveals the job number.
When I look at all the jobs listed in dba_scheduler_jobs, nothing seems
likely to be this mysterious job 2915.
Does anyone have any idea how I can locate it?
Thanks!

Hi,
Actually I've been meaning to write this info up as a DBA tip, but never get round to doing it...
The job number referred to is in fact the Object ID of the Job when dealing with a new Scheduler job and not an original DBMS_JOB job.
Scheduler jobs are database objects now rather than just 'rows in a table' so have an object ID, visible in dba_objects. But the dba_scheduler jobs view does not display this column!
See this example, I create a Job that refers to a non existant procedure. The object ID matches that put into the alert log when it fails only a second later:
SQL> declare
  2    jname varchar2(30) := 'JOB_TEST';
  3    jtype varchar2(16) := 'PLSQL_BLOCK'; -- 'PLSQL_BLOCK', 'STORED_PROCEDURE', 'EXECUTABLE'
  4    jaction varchar2(256) := 'not_a_real_proc;';
  5  begin
  6
  7    dbms_scheduler.create_job (
  8                  job_name        => jname,
  9                  job_type        => jtype,
10                  job_action      => jaction,
11                  start_date      => systimestamp,
12                  enabled         => TRUE,
13                  auto_drop       => FALSE,
14                  comments        => 'Test job can be dropped'
15                  );
16
17  end;
18  /
