When you try to access the Managed Metadata Service Application from manage Service Applications, you face the following error:
"The Service Application being requested does not have a connection associated with the Central Administration web application. To access the term management tool use the site settings from a site configured with the appropriate connection"
While trying to add the BCS catalog at the External List on a site or trying to add the BCS catalog while creating a sync connection for a BCS source in User profile Service application, we get the following error,
"The Business data connectivity metadata store is unavailable. Check configuration and try again"
While BCS sync step is run during an UPA profile sync, we might see this error in ULS logs
