I had recently a problem with my System Center Operations Manager 2012 (RTM) activities on my Orchestrator 2012 SP1 runbook servers.
All runbooks with SCOM activities failed. So I created a test runbook with only on SCOM activity (Get Monitor), enabled logging and checked what the error is.
The error text was: Failed to load the object properties. The exception was “Input string was not in a correct format.”.
The web search did not help and I tried a lot: restarted server, redeployed SCOM integration pack, started SCOM console, which was working, tried with a new SCOM connection. Nothing helped.
So I opened a ticket with Microsoft support and they really helped very fast. Thanks!
The solution was this:
The problem was the Operations Manager Console cache, which was corrupted.
- To clean up this, recreate the SCOM connections with the same name.
- Start the SCOM console with the clear cache option:
"C:\Program Files\System Center Operations Manager 2012\Console\Microsoft.EnterpriseManagement.Monitoring.Console.exe" /clearcache
