Checkout/check-in replication

Jump to: navigation, search

A type of geodatabase replication that involves copying data to a destination geodatabase, editing that data in the destination, and then merging the changes with the source geodatabase. In ArcGIS and ArcSDE, the destination can be a file, personal, or ArcSDE geodatabase, while the source must be an ArcSDE geodatabase. Once the data is merged (synchronized), checkout/check-in replication is completed.[1]

Checkout/check-in replication allows data to be copied to another geodatabase, edited, and then transferred back to the original database. With this replication method the check-in operation can only be performed once; if more edits are needed after the data has been checked in, another checkout replica must be created.[2]

In ArcGIS software, replicas are managed using Replica Manager. With this utility, relicas can be renamed, refreshed, the properties of each replica can be reviewed, and datasets can be removed from a replica. All replicas may also be viewed with a role of parent or child; list only checkout/check-in, one-way, two-way, or all types of replicas; and the replica log may be viewed. This utility is available in both ArcCatalog and ArcMap.[3]
