Microsoft Replication Manager is a tool included with the Microsoft Access
Developer's Toolkit (ADT) for Windows 95, version 7.0, and with Microsoft
Office 97 Developer Edition Tools. An important feature of Microsoft
Replication Manager is its ability to manage members of a replica set and
schedule synchronizations between them.
One of the components that Microsoft Replication Manager uses to control
synchronization is the Synchronizer (formerly known as the Transporter in
Microsoft Replication Manager 3.0). The Synchronizer is a program that runs
in the background and allows database changes to be stored in a dropbox
folder for later synchronization. This is especially useful when you are
distributing your application to users with portable computers that are not
always connected to the network.
When initiating synchronization between members of a replica set managed by
multiple Synchronizers, each Synchronizer selects one replica that sends
changes to and receives changes from a member of the replica set managed by
a different Synchronizer. Likewise, when initiating a local synchronization
of a replica set managed by one Synchronizer, Microsoft Replication Manager
selects one replica that sends changes to and receives changes from all
other replicas in the set. This replica is called the "base" or "gateway"
replica.
This article discusses how the Synchronizer determines which replica is
designated as the base replica, and what problems may occur as a result.
NOTE: This article assumes you have previously configured Microsoft
Replication Manager and are currently managing multiple members of a
replica set.
