Synchronize Changes (Data Management)

Summary

Synchronizes updates between two replica geodatabases in a direction specified by the user.

Usage

• This tool is used when synchronizing replicas in connected mode.

• Two-way, one-way, and check-out replicas can be synchronized with this tool.

• The replica geodatabases can be local geodatabases or geodata services.

• Once synchronized, the changes (edits) will be reflected in the target geodatabase and viewable by all users.

Syntax

SynchronizeChanges(geodatabase_1, in_replica, geodatabase_2, in_direction, conflict_policy, conflict_definition, reconcile)

Parameter	Explanation	Data Type
geodatabase_1	The geodatabase hosting the replica to synchronize. The geodatabase may be local or remote.	Workspace; GeoDataServer
in_replica	A valid replica with a parent contained within one input geodatabase and a child in the other input geodatabase.	String
geodatabase_2	The geodatabase hosting the relative replica. The geodatabase may be local or remote.	Workspace; GeoDataServer
in_direction	Specifies the direction in which the changes will be sent: from geodatabase 1 to geodatabase 2, from geodatabase 2 to geodatabase 1, or to send changes in both directions. For check-out/check-in replicas or one-way replicas, there is only one appropriate direction. If the replica is two-way, then any of the three choices are available. BOTH_DIRECTIONS —Changes will be synchronized in both directions. This is the default FROM_GEODATABASE2_TO_1 —Changes will be synchronized from geodatabase 2 to geodatabase 1. FROM_GEODATABASE1_TO_2 —Changes will be synchronized from geodatabase 1 to geodatabase 2.	String
conflict_policy	Specifies how conflicts are resolved when they are encountered. MANUAL —Manually resolve conflicts in the versioning reconcile environment. IN_FAVOR_OF_GDB1 —Conflicts resolve in favor of geodatabase 1. This is the default. IN_FAVOR_OF_GDB2 —Conflicts resolve in favor of geodatabase 2.	String
conflict_definition	Specifies how conflicts will be defined. BY_OBJECT — Any changes to the same row or feature in the parent and child versions will conflict during reconcile. This is the default. BY_ATTRIBUTE — Only changes to the same attribute (column) of the same row or feature in the parent and child versions will be flagged as a conflict during reconcile. Changes to different attributes will not be considered a conflict during reconcile.	String
reconcile	Specifies whether to automatically reconcile once data changes are sent to the parent replica if there are no conflicts present. This option is only available for check-out/check-in replicas. DO_NOT_RECONCILE —Do not reconcile with the parent version. This is the default. RECONCILE —Reconcile with the parent version.	Boolean

Derived Output

Name	Explanation	Data Type
out_geodatabase_1	The geodatabase hosting the replica to synchronize.	Workspace; GeoDataServer
out_geodatabase_2	The geodatabase hosting the relative replica.	Workspace; GeoDataServer

Code sample

SynchronizeChanges example (Python window)

The following Python window example demonstrates how to use the SynchronizeChanges function in the Python window.

import arcpy
arcpy.env.workspace = "C:/Data"
arcpy.SynchronizeChanges_management("MyData.sde", "My2wayReplica", 
                                    "MyData_child.sde", "BOTH_DIRECTIONS",
                                    "IN_FAVOR_OF_GDB1", "BY_ATTRIBUTE")

SynchronizeChanges example 2 (stand-alone script)

The following demonstrates how to use the SynchronizeChanges function in a stand-alone Python script.

# Name: SynchronizeChanges_Example2.py
# Description: Synchronizes changes for a one way replica from the Parent 
# to the child replica geodatabase. The parent is an enterprise geodatabase workspace, and the 
# child is file geodatabase.

# Import system modules
import arcpy

# Set workspace
arcpy.env.workspace = "C:/Data"

# Set local variables
replica_gdb1 = "MyData.sde"
replica_gdb2 = "Counties_replica.gdb"
replica_name = "MyOneWayReplica"
sync_direction = "FROM_GEODATABASE1_TO_2"
conflict_policy = "" 				# Not applicable for one way replicas, there is not conflict detection.
conflict_detection = ""  # Not applicable for one way replicas, there is not conflict detection.
reconcile = ""           # Only applicable for Checkout replicas

# Execute SynchronizeChanges
arcpy.SynchronizeChanges_management(replica_gdb1, replica_name, replica_gdb2, 
                                    sync_direction, conflict_policy, 
                                    conflict_detection, reconcile)
