You can manage replicas using Replica Manager. With this utility, you can rename, refresh, and review the properties of each replica as well as remove datasets from a replica. You may also view all replicas with a role of parent or child; list only checkout/check-in, one-way, two-way, or all types of replicas; and view the replica log. This utility is available in both ArcCatalog and ArcMap.

To open Replica Manager, click the Manage Replicas button on the Distributed Geodatabase toolbar. The combo box at the top of the replica manager allows you to control the types of replicas that are listed. By default, all types are listed, but the list can be limited to just checkout, just one-way, or just two-way replicas.

The Replica Manager displays the following properties for all replicas listed:

By right-clicking an individual replica, you bring up a context menu with the following options:

The replica log

The replica log is only available for two-way and one-way replicas. To open the replica log from the Replica Manager, right-click on the replica whose log you want to view and choose View Log. The replica log maintains a record of the data messages sent and received by the replica.

At the top of the dialog box is the replica's name whose log you are currently viewing.

You can choose to sort messages in two ways:

The replica log shows the log date, event, and result for each message.
Log Date—The date and time of messages sent or received
Event—Whether the message was sent (sent changes) or received (rec changes) by this replica
Result—Displays if the message was sent or received successfully or if it caused a conflict when imported to the replica
If the Result column shows that there is a conflict, you can right-click the message that is in error to view the error report. The error report describes why there is a conflict and details the steps involved to remove the replica from its conflict state.

Replica properties

To view the properties of a replica, right-click the replica in Replica Manager and click Properties. This will bring up the replica properties dialog box, which contains three tabs: General, Description, and Advanced.

  1. General
  2. Under the General tab, the following replica properties are displayed:

  3. Description
  4. The Description tab in the Replica Properties dialog box shows the datasets that are included in the replica. Columns for these datasets are displayed reflecting the properties chosen from the replica creation process. These dataset properties include the following:

    To remove a dataset from the replica, right-click the dataset and choose UnRegister from Replica. The replica will no longer reference the dataset; however, it still remains in the geodatabase. To remove a geometric network or topology, you must remove all the classes at once.

    To view the filters that were applied to the replica dataset during replica creation, right-click the dataset and choose View Filters.

    A sentence at the bottom of the dialog box indicates if related features and rows are replicated or if related features and rows are not replicated.

    A second sentence describes how the replica geometry is applied. For example, by default, features and layers that intersect the geometry are added, but other spatial relations, such as must be completely inside, could have been set at creation time. If the Use Geometry column is set to True, then this statement applies. If the Use Geometry column displays False, then the full extent of the dataset is used to determine what gets replicated for that particular dataset and not the spatial extent of the replica area.

  5. Advanced
  6. The Advanced tab in the Replica Properties dialog box shows information about the generation numbers associated with the replica. The generation number is a number maintained by the geodatabase that keeps track of messages being sent and received by the replica. For example, the first data change message sent from one replica to its relative would make the current generation of the replica 1. When the relative imports that message, its relative replica generation gets set to 1. When the replica receives an acknowledgment of the data change message, its last acknowledged generation gets set to 1. The Advanced panel displays the following information about generation numbers:

    The Relative Replica Connection contains the connection information of the relative replica. You can set this information by browsing to the location of the relative replica's connection file. After doing so, the Persist user name and password check box becomes enabled. If you check this box, the user name and password will persist; otherwise, they will not persist. By default, these will not persist for security reasons. The connection information is used when you run the synchronize command or the synchronize geoprocessing tool to automatically fill in the relative replica's information. This prevents you from having to browse when running synchronize. If the user name and password do not persist, it will prompt you.

    When replicas are created, the parent replica stores the child replica's geodatabase connection information. The child, however, does not store the parent replica's geodatabase connection information. You may want to set this to prevent having to browse during synchronization.
