You need to have an old backup of MSDB database, then restore it with another name and check in sysjobs table if the jobs existed in that time are the same that you has now:
SELECT *
FROM sysjobs
ORDER BY name

Open in new window

You can try slubek's solution but if don't works then only with an old backup you'll know which jobs were deleted.

slubek,

both query seems the same, and it just has the job_id and instance_id, hard to tell which is which, right?

Vitor,

yeah, the restore of MSDB is the last sort, but it didn't say who delete that, right?

"With that you'll need a log reader (usually a 3rd party software) that will be able to read a transaction log and then you'll found who and when deleted the job. "

Apex Log for example ? you are trying to see what is inside that transcation log of MSDB ?

Yes. If you have Apex log then you can give a try on it.

Ouch...

By default MSDB uses simple recovery. So, unless you can interrogate MSDB itself, then it is going to be very difficult to find out "who" deleted the job.

Have you changed MSDB log to be full recovery ?

You might be able to find out the last time a job was executed, and then try to pinpoint activity during that time frame to see who was active at the time, but I think you will be out of luck.

Sorry about the bad news...

I will do a few searches on information and books that I have access to and see if there is any other glimmer of hope.

One thought to help pinpoint is querying the sysjobsteps

Mark,

good to see you here again !

"

no. so this mean it is a must ?


one question, anyone know if Apex Log tools can open the MSDB log when MS SQL is operating?

"EXECUTE msdb.dbo.sp_sqlagent_log_jobhistory "

this one need a @job_id

EXECUTE msdb.dbo.sp_sqlagent_log_jobhistory @job_id = 'D64C99DF-2A19-402C-A404-C4D768704E8E';

prompts an error:

Msg 201, Level 16, State 4, Procedure sp_sqlagent_log_jobhistory, Line 0
Procedure or function 'sp_sqlagent_log_jobhistory' expects parameter '@step_id', which was not supplied.

"is going to be very difficult to find out "who" deleted the job."

so can only from the  MSDB log file anyway, right ?

If you are trying to find out who deleted a job by inspecting the log files, then yes, the log file would need to be as a result of having Full Recovery mode set on your MSDB (which is auto reset to simple everytime you run setup).

(BTW: I was in the middle of editing my post as you were reading it. Should have been querying sysjob... as per what can now be seen in my previous entry don't worry about that execute unless you know all the params)

Mark,

you mean you write this post:

?

so as long as my MSDB is not in full recovery mode then nothing can be done. so this is it.

"Sometimes "it can't be done" is the correct answer, as much as we may wish it to be otherwise."

MS DBA exam like this !

"Or, if scheduling user generated tsql procedures, you can track modifications to those procedures using DDL triggers : http://technet.microsoft.com/en-us/library/ms186406.aspx  (I think we have discussed DDL triggers before) "

yes, but if someone use a system account to create that procedure, we can't do anything anyway, right?
