Debugging dbms_scheduler jobs

Oracle Database Tips by Donald BurlesonJune 9, 2015

Question:  I have a dbms_scheduler job which appears to be throwing an error.  I cannot find the error and I don't know how to to troubleshoot the Oracle job scheduler.  Are their specific steps for diagnosing a dbms_scheduler job?

Answer:  For complete information on debugging Oracle jobs using dbms_scheduler, I recommend the great book "Oracle Job Scheduling" by Dr. Tim Hall.  Also see how to fix broken jobs in dbms_scheduler.

You can see dbms_scheduler errors in the dba_scheduler_job_run_detail view:

COL log_id              FORMAT 9999   HEADING 'Log#'
COL log_date            FORMAT A32    HEADING 'Log Date'
COL owner               FORMAT A06    HEADING 'Owner'
COL job_name            FORMAT A20    HEADING 'Job'
COL status              FORMAT A10    HEADING 'Status'
COL actual_start_date   FORMAT A32    HEADING 'Actual|Start|Date'
COL error#              FORMAT 999999 HEADING 'Error|Nbr'

TTITLE 'Scheduled Tasks That Failed:'

--   job_name = 'MYJOB'

   status <> 'SUCCEEDED'
