Application Deployment targets showing metric collection errors

On Grid Control 11.1.0.1.0, running on Weblogic 10.3.2 I had some errors on


/secFarm_GCDomain/GCDomain/EMGC_OMS1/emgc
/secFarm_GCDomain/GCDomain/EMGC_OMS1/OCMRepeater


'Application Deployment' targets, showing metric collection errors on the Grid Control.


For database targets, this is easy to solve by entering the right dbsnmp password :
Targets - Configure 




Now the errors on 'Application Deployment' targets are also easy. Just go to Targets , select the target and click configure. Now there are no configurable properties, no passwords or such, but just click OK button.

After a few seconds (almost instantly) the target is shown 'Up' in Grid Control.

How easy can it be?
