For example :

The ip 10.244.10.75 is ok but in  opmanager  is down

When I click on10.244.10.75 appears the image below:

Another information I already did the steps:

Stop OpManager.
Run repairdb.bat from OpManagerin directory.
Rename the logs folder present under OpManager home directory.



Start OpManager.
