A quick tour of synchronizing connected replicas

This topic applies to ArcEditor and ArcInfo only.

To synchronize replicas in a connected environment, you can use the Synchronize Changes wizard in ArcGIS Desktop. To learn about synchronizing in a connected environment, see Connected synchronization.

The wizard provides the following options:


Connected synchronization allows you to choose the direction in which the changes will be sent. For example, for two-way replicas, you can send changes to the relative replica, get changes from the relative replica, or move changes in both directions. If you choose both directions, changes are first sent in one direction and then sent in the opposite direction, all in one operation. For checkout replicas, only the option to send changes from the child replica to parent replica option is available. For one-way replicas, only the option to send changes in one direction is available. Either from parent-to-child or child-to-parent.

Reconcile Options

During synchronization, a reconcile and post may occur between the synchronization version and the replica version. For information on the synchronization and replica versions and on when reconciles occur, see synchronization and versioning. During this reconcile process, conflicts may occur. You can choose a reconcile policy to define how to handle these conflicts. Reconcile policies include the following:

The default policy is for the parent replica's representation to be used. This can be either in favor of geodatabase1 or in favor of geodatabase2, depending on which one contains the parent replica.

For two-way replication, if you choose to synchronize in both directions, you cannot choose a manual reconcile policy.

You can also choose between column level and row level conflict detection for this reconcile.

The import phase of the synchronization process occurs within a transaction. The second phase of a synchronization includes a reconcile, which also occurs in a transaction. Resources needed, such as undo space or logical log files, will vary with the amount of changes to be synchronized. If the import phase completes but the reconcile phase returns an error, the replica will appear as if in conflict and you can later go in and complete the reconcile manually.
