A database synchronization system for synchronizing a plurality of local databases in a plurality of distributed computing systems is disclosed. The plurality of distributed computing systems form a distributed computing environment (DCE). The synchronization system includes a system server, a registry database, coupled to the system server, a local area network (LAN) synchronization server, coupled to the system server, a LAN server synchronization library, coupled to the system server, and a LAN server, coupled to the LAN synchronization server and selected ones of the plurality distributed computing systems forming a LAN. Synchronization between the LAN and the DCE registry occurs when registry modifications in the registry database affecting at least one of the plurality of local LAN databases invokes the LAN server synchronization library to synchronize the affected database. The synchronization system utilizes a registry database coupled to each of the local databases. A primary replica is coupled to the registry database that synchronizes each local database within the DCE with the registry database. A secondary replica is then coupled to the primary replica, that synchronizes at least one local area network (LAN) server that includes selected ones of the plurality of computing systems and their respective databases with the registry database.

A method and architecture for the administration of large cells in an Open System Foundation/Distributed Computing Environment (OSF/DCE). The architecture organizes the Cell Directory Service (CDS) name space of the OSF/DCE to allow a network administrator to easily determine network resources under their control, and work with a subset of the network resources. The OSF/DCE name space is organized as resource realms having a CDS component and a registry component. The CDS component of the resource realms has a fixed portion containing at least two roots describing sub-systems and realm resources (e.g., printer, serial devices, etc.). The CDS component also contains individual realms defined directly below the fixed portions. The registry component has a root consisting of the security, group and realm portions. Individual realms are defined as directories below the root. The resulting resource manager which allows the OSF/DCE name space to be organized/partitioned into separate, administrable name spaces which allows easy determination as to what resources are controlled by the administrator, and easily administrable subsets of network resources.
