During the past years, Grid Computing has emerged as an important research field concerning to large-scale resource sharing. Several research and academic institutions have widely adopted this technology as a mechanism able to integrate services across distributed, heterogeneous, and dynamic virtual organizations. However, this rapid expansion is exposing the need to provide effective means to manage virtual organizations, especially those questions related to the insertion and maintenance of grid nodes. This paper proposes a flexible and automated method based on policies to cope with these requirements. Policies constitute a mechanism for specifying the behaviour a grid node must exhibit. In this work we present a policy-based management architecture, which makes use of COPS-PR to exchange information about specific parameters related to grid nodes based on Globus Toolkit 2.4. Moreover, we have also added new classes to the Framework PIB (Policy Information Base) in order to represent configuration data about the different components of this toolkit.
