    @Andre –

    There shouldn’t be a reason to run Remove-SCOMDisabledClassInstance on a daily or even regular basis, as this will only be needed when creating an explicit disable via override to a discovery. However, at the same time, it should not hurt anything to do that.

    Nice Article – I have same problem after update to .net 4.5.2 – with the "A Bind Data Source in Management Group Production has posted items to the workflow, but has not received a response in 1510 seconds. This indicates a performance or functional problem
    with the workflow.
    Workflow Id : Microsoft.SystemCenter.CollectDiscoveryData
    Instance :
    Instance Id : {B3FA7F2F-3D4A-236D-D3FD-119B3E01C3E3}
    but you say :What we found – was one of the MP’s – the Dell Hardware MP – was consuming a large amount of SQL server CPU time, just to queries some standard Managed Type views in the database, many of these lasting over 10 minutes." – how did you find out of
    are there some queries or SQL profiler specifics settings

    Thanks for posting 🙂

    I see that you are receiving a few 2115s. Did you try checking the connection between MS & the SQL Server hosting OpsDB?
    You can try a UDL file test -> Create a file by name TestCon.udl in the management server. Open it and try connecting to the SQL server and check if the connection looks okay.

    we have the same issues, and trying to get it resolved.

    I saw somewhere another way of running the Remove-SCOMDisabledClassInstance command, and I built that into a loop, so just kick it off, and it will go on and on until it finally runs without exception:

    [Reflection.Assembly]::Load("Microsoft.EnterpriseManagement.Core, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
    [Reflection.Assembly]::Load("Microsoft.EnterpriseManagement.OperationsManager, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")

    $exit = $false
    $i = 0
    write-host ""
    write-host "Attemtp $i ***************************************"
    write-host ""
    $i += 1
    $mg = [Microsoft.EnterpriseManagement.ManagementGroup]::Connect("localhost")
    "completed successfully so to time to exit the loop"
    $exit = $true
    catch { write-host $error[0].exception }
    } until ($exit -eq $True)

    I intend to create a scheduled task which I execute every day, just to keep SCOM clean… and with the above script it always runs till it has finished cleaning…
