Bringing Down a DBMS_JOB

1. Find the Job You Want to Bring Down
2. Mark the DBMS_JOB as Broken

SQL> EXEC DBMS_JOB.BROKEN(job#,TRUE);

All this command does is mark the job so that if we get it to stop, it won’t start again. Let’s make one thing perfectly clear, after executing this command the job is still running.

3. Kill the Oracle Session

ALTER SYSTEM KILL SESSION ‘sid,serial#’;

 4. Kill the O/S Process

For Windows, at the DOS Prompt: orakill sid spid

For UNIX at the command line> kill ‘9 spid

5. Check if the Job is Still Running

If No , Then you are Done , But if Job Still Running Go To Step 6.

6. Determine the Current Number of Job Queue Processes

SQL> col value for a10
SQL> select name,value from v$parameter where name = ‘job_queue_processes’; 

7. Alter the Job Queue to Zero

SQL> ALTER SYSTEM SET job_queue_processes = 0;

 8. Validate that No Processes are Using the Job Queue
9. Mark the DBMS_JOB as Not Broken

SQL>EXEC DBMS_JOB.BROKEN(job#,FALSE):

10. Alter the Job Queue to Original Value

ALTER SYSTEM SET job_queue_processes = original_value;

11. Validate that DBMS_JOB Is Running
