The GDMP client-server software system is a generic file replication tool that replicates files securely and efficiently from one site to another in a Data Grid environment using Globus Grid tools. In addition, it manages replica catalogue entries for file replicas and thus maintains a consistent view on names and locations of replicated files. Files to be transferred can be of any particular file format and GDMP treats them all in the same way. However, for Objectivity database files a particular plug-in exists. All files are assumed to be read-only.
