Object Reference not set to an instance of an object with Timer Job Definitions

    Question

  • Hi,

    On our sandbox environment (SP Server 2010: WFE + App + DB, CU Dec 2010 on Windows Server 2008 R2), I had to remove orphaned site collections which were leftovers from a previously removed Project Server Web application. To do this I carried out steps described in http://social.technet.microsoft.com/Forums/en-US/projserv2010setup/thread/b26dadd1-95a6-451b-ab7f-536418108cec. This seemed to have worked well, to the extent that the errors we had before, were now gone. Great! Unfortunately a quick scan revealed that we got some other errors in return :-).

    From what I can make of it, it seems that the farm is now struggling with missing Timer Job Definitions. In fact the system shows two different symptoms, but both seem to relate to the same thing.

    1.   When I try to open the jobdefinitions page on CA (http://<CA URL>/_admin/ServiceJobDefinitions.aspx) I get  "Object Reference not set to an instance of an object" error.

    2.   In eventlog groups of 4 errors (Event ID 6464) appear at regular intervals. (details are at the bottom of this message).The 4 errors only differ where the id is put. There are 4 different Id's in play:

    feb4f1bd-721b-4cbc-9903-fb0636e38665

    03f3f0ff-c096-4df4-99db-856001d2988c

    af3cb559-2a9f-4d3f-a957-9420c3c5368c

    dee650f1-3c07-453a-bc54-d5ecce1b6a39

     

    I have tried running config wizard already without any luck. Also tried re-installing CU (but this of course did not work as the update was already applied and nothing was installed)

    Here's detail of one error in eventlog. Thanks for any suggestions that might help resolving this issue.

  • This could be one of the possibility

    -> Looks like you have deleted some of the service application. And when you navigate to the timer job defintion page, which might be still referring to the service applications which are deleted now, it might have thrown this error. After deleting those timer job definitions (may be after few mins, could be because of cache) it should have got loaded again.

  • UPDATE - more info

     

    Since my initial posting I identified the offending timer jobs, using the get-sptimerjob cmdlet. The id's of the timerjobs in question are highlighted in the extract from the console shown below:

    PS C:\Users\PS_SPFarmAdmin> get-sptimerjob | where-object {$_.name -like "PWA*"}

     | format-list name, id

    Also restarted Sharepoint Timer service and did iisreset. However, when I go back to the ServiceJobDefinitions page, it still ends up in the same ‘object reference not set ….’ Error.

    The obvious next thing to do seems to be to delete the SPTimerJobs. How can I delete SPTimerjobs in SP 2010 though? Powershell does not have a cmdlet similar to the stsadm operation called deletessptimerjob. Moreover this operation seems to have been removed from the (deprecated) stsadm utility as well.

    Any help is welcome.

  • wow! couple of minutes after my previous post, and the ServiceJobDefinitions page displays again! No idea what may have caused the page to function now, but I'm guessing that after disabling the SPTimerjobs, some other TimerJob kicked in and cleaned up any loose ends.

    Would like to read some of your opinions about this though.

    Thanks

  • You can assign the job to a variable and use the delete method to get rid of it.

     

    $job = Get-SPTimerJob <guid>

    $job.delete()

  • Hi Kurt and Sean,
    I ran into the same situation and deleting the affected jobs did the trick for me. Thanks for the outline of the solution.

  • After migrating a PWA site from one farm to another, I got the same "Object Reference not set to an instance of an object"-error instead of the Timer Jobs list.

    Got this in the ULS logs:

    System.NullReferenceException: Object reference not set to an instance of an object.
     Microsoft.Office.Project.Server.Administration.ServerScheduledTimerJob.get_DisplayName()
     Microsoft.SharePoint.ApplicationPages.JobDefinitionsDataSourceView.AddRow(SPJobDefinition jd, DataTable table, DataSourceSelectArguments selectArguments)

    - In bold is what led me to doing the following:

    PS C:\> $FUBARjob = Get-SPTimerJob | Where-Object {$_.DisplayName -eq $null}
    PS C:\> $FUBARjob
    
    Name                 Schedule             Last Run
    ----                 --------             --------
    PWASSP_71ae9cba-4... daily between 00:... 1/1/0001 12:00:00 AM
    
    
    PS C:\> $FUBARjob.Description
    Project Server Shared Timer Job
    PS C:\> $FUBARjob.Delete()

    Which solved my problem, being an orphaned PWA job without a displayname :)

  • Rune,

    I ran across this same issue you described in your post and ran your script but it doesn't return a description of the 2 timerjob that have a null desription.  I have disabled these jobs but it seems they need to be deleted to solve the problem.  Can you guide me in the right direction to delete the jobs by GUID. 

    I appreciate your help.

  • Hey Scott,

    Late reply, sorry - I am not receiving notifications by mail.

    Maybe your issue is a different one (by the way, the commands wont return a description if that one is null, and they will only return anything if DisplayName is null), but if you know the Id of the timerjob, use this:

    PS C:\> $FUBARjob = Get-SPTimerJob | Where-Object {$_.Id -eq '<ID_OF_THE_JOB>'}
    PS C:\> $FUBARjob #(To verify the existance of that job)
    PS C:\> $FUBARjob.Delete()

    Or, if you know the Name, use this:

    PS C:\> $FUBARjob = Get-SPTimerJob | Where-Object {$_.Name -eq '<NAME_OF_THE_JOB>'}
    PS C:\> $FUBARjob #(To verify the existance of that job)
    PS C:\> $FUBARjob.Delete()
