A method for managing a resource configuration of a heterogeneously managed computer system. During processing of a resource management request, retrieving a set of resource tags are retrieved. Each resource tag associates a local resource identifier that is assigned within a first configuration management domain with an index identifier that is assigned within a second configuration management naming domain. The retrieved tags are mutually associated utilizing the index identifiers to generating a system configuration map. The resource management request is compared with the system configuration map to identify target resources and corresponding target resource information. One or more resource queries are generated based on the identified target resource and corresponding target resource information.
