Chapter 27. Access and the Internet > Replication Over the Internet

Replication Over the Internet

The Access 97 Replication Manager can be installed on an Internet or intranet server so that you can configure replicas to synchronize with replicas on the server. The replica on the Internet or intranet server is considered the hub since all other replicas synchronize with it.

During synchronization, each client machine makes an HTTP connection with an Internet or an intranet server. Direct synchronizations can't be performed over the Internet; instead, an FTP folder on the server acts as a dropbox folder for an indirect synchronization. It works like this: The client machine builds a message file containing all the design and data changes made since the replicas were last synchronized. This message file is placed in the FTP file location on the Internet or intranet server. The Synchronizer on the Internet or intranet server applies the changes to its local replica, then builds a message file with all the design and data changes made since the client and server replicas were last synchronized. These changes are also placed in the FTP file location. The server sends the message file's name and location back to the client workstation. The client then transfers the message file from the server to the client workstation by using FTP. All the changes specified in the message file are applied to the client replica. The client machine doesn't need to have a Synchronizer because Jet and Windows DLLs handle the synchronization.
