How do I remove and active alert which has become 'orphaned'.
The alert states "An object of type MonitoringAlert with id fafa7d12-9c26-458f-bb14-cee7b1690ffb was not found.

The Message body is as follows :-

Note:  The following information was gathered when the operation was attempted.  The information may appear cryptic but provides context for the error.  The application will continue to run.

Microsoft.EnterpriseManagement.Common.ObjectNotFoundException: An object of type MonitoringAlert with Id fafa7d12-9c26-458f-bb14-cee7b1690ffb was not found.
   at Microsoft.EnterpriseManagement.ManagementGroup.GetMonitoringAlert(Guid id)
   at Microsoft.EnterpriseManagement.Mom.Internal.UI.Cache.AlertPropertySet.GetObject()

   at Microsoft.EnterpriseManagement.Mom.Internal.UI.Console.ConsoleJobExceptionHandler.ExecuteJob(IComponent component, EventHandler`1 job, Object sender, ConsoleJobEventArgs args)
 
Any ideas on how to clean up this event would be most appreciated.

SCOM Version 2007 R 2

Hi

Have you tried starting the console with the /clearcache switch?

As Kevin states - Keep in mind - this is no longer recommended post SP1 RTM..... just when you are having a problem.

Ive had what sounds like a similar problem. If these alerts are not showing up on other consoles or via the web console I think the solution is to delete the momcache.mdb which, in my case, is in ~\Documents and Settings\(userID)\Local Settings\Application Data\Microsoft\Microsoft.Mom.UI.Console

hope this helps

Hi shetauq,

I am using SCOM 2007 R2. momcache.mdb deletion worked for me.

Thanks

Clearing the momcache.mdb worked successfully for me too. I am using SCOM 2007 R2.

 

Thank you!

momcache.mdb deletion worked for me.

using SCOM 2007 R2

Thanks

Same for me.

Running SCOM 2007 R2 as well.

Shetauq's solution worked for me as well to clear out a warning alert for WMI script failing.
