System for providing synchronization between a local area network and a distributing computer environment

A synchronization system for use in a distributed computing environment (DCE), comprising:

• a registry database coupled to each of a plurality of local DCE databases within each computing system within the DCE;
• a primary replica, coupled to the registry database, that synchronizes each of said plurality of local DCE databases within the DCE with the registry database, wherein each of said plurality of DCE databases is synchronized by the primary replica;
• and
• a secondary replica, coupled to the primary replica, that synchronizes at least one local area network (LAN) server comprising selected ones of the plurality of computing systems and their respective LAN databases with the registry database, wherein the LAN databases are synchronized by the secondary replica.

In a plurality of distributed computing systems, each having a local database, forming a distributed computing environment (DCE), a method for synchronizing the plurality of local databases comprising:

• providing primary communication from one computing system to another computing system and with a registry database within the DCE;
• establishing a secondary communications server for a local area network (LAN) of computing systems selected from the plurality of computing systems in the DCE;
• establishing a LAN server synchronization library;
• determining whether registry modifications in the registry database affect at least one of the plurality of local databases within the LAN;
• invoking the LAN server synchronization library to synchronize the affected database.

• establishing a primary replica that synchronizes each of said plurality of local DCE databases within the DCE with the registry database, wherein each of said plurality of DCE databases is synchronized by the primary replica;
• and
• establishing a secondary replica that synchronizes at least one local area network (LAN) server comprising selected ones of the plurality of computing systems and their respective LAN databases with the registry database, wherein the LAN databases are synchronized by the secondary replica.

A computer program product for use in a plurality of distributed computing systems, each having a local database, forming a distributed computing environment (DCE), the product for synchronizing the plurality of local databases comprising:
