Create Replica (Production Mapping)

概要

Creates a replica to a personal, file, or enterprise geodatabase from a specified list of feature classes, layers, datasets, and/or tables in an enterprise geodatabase. Optionally use a filter geometry from another feature layer to replicate features within an area of interest.

使用法

• All datasets must be from the same ArcSDE database.

• This tool is similar to the Create Replica tool in the Data Management toolbox. This tool allows you use a selected feature in another feature layer as an area of interest for replicated features. Any features from Replica Datasets (in_datasets) that intersect or are contained by the selected feature in Filter Feature Layer (in_features) will be replicated to the Child Workspace (in_childworkspace).

• Data replicated with the ONE_WAY and TWO_WAY options must have a populated Global ID type field. Use the Add Global IDs tool in the Management toolbox to create and populate a global id field in your data.

• For check-out and one-way replicas the child replica geodatabase can be an ArcSDE, file, or personal geodatabase.

• For two-way and one-way child–to–parent replicas the child geodatabase must be ArcSDE.

• To use archiving for one-way replicas the parent workspace must be connected to the Default version. For one-way child to parent replicas the child workspace must be connected to the Default version.

• Use selection sets and layer definition queries to limit or specify features to replicate. To do this in ArcCatalog, use the Make Feature Layer tool or create layer files for Replica Datasets (in_datasets).

• To use this tool in a stand-alone script, check out a production mapping foundation license: arcpy.CheckOutExtension("Foundation").

CreateReplica_production (in_datasets, in_replicatype, in_childworkspace, in_replicaname, {in_reuse_schema}, {in_usefilter}, {in_filtertype}, {in_features})

パラメータ	説明	データ タイプ
in_datasets [in_datasets,...]	The data that is going to be replicated. This can consist of individual feature classes and tables or entire datasets.	Feature Layer; Table View; Dataset
in_replicatype	The type of replica to create: CHECKOUT —Creates a replica in which the changes can be checked back into the parent geodatabase from the child. This is the default. ONE_WAY —Creates a replica in which changes cannot be transferred from the child to the parent, but changes can be continually synchronized from the parent to the child. TWO_WAY —Creates a replica in which changes can be transferred from the parent to the child and vice versa.	String
in_childworkspace	The path to and name of the workspace that is going to contain the replicated data.	Workspace; GeoDataServer
in_replicaname	The name of the replica you are going to create.	String
in_reuse_schema （オプション）	Indicates whether to reuse a geodatabase that contains the schema of the data you want to replicate. This reduces the amount of time required to replicate the data. This option is only available for check-out replicas. DO_NOT_REUSE —Do not reuse schema. This is the default. REUSE —Reuse schema.	String
in_usefilter （オプション）	Replicates features that either intersect or are contained by features in the in_features feature layer. TRUE —Applies the filter set in in_filtertype. You must set in_filtertype and in_features. FALSE —Does not apply the spatial filter. This is the default.	Boolean
in_filtertype （オプション）	Specifies the spatial relationship between in_datasets and in_features. INTERSECTS —Extract features from in_datasets that intersect features in in_features. This is the default. CONTAINS —Extract features from in_datasets that are contained by the selected feature in the in_features.	String
in_features （オプション）	Feature layer with one selected feature.	Layer

コード サンプル

CreateReplica example 1 (Stand–alone Python script)

This script demonstrates the use of the Production Mapping CreateReplica tool. The script creates a replica of Production Mapping SoCal sample data stored in ArcSDE. The script selects a single feature in the CoastA feature class. The script creates a replica of all TreesA features that intersect the selected feature in CoastA. Replicated features are written to a file geodatabase.

# Name: CreateReplica.py
# Description: Creates a checkout replica from the SoCal sample data
# Author: ESRI
# Date: March 2010

import arcpy

# check out a foundation license
arcpy.CheckOutExtension("Foundation")

# import the production mapping toolbox - you may have to change this path
arcpy.ImportToolbox(r'C:\Program Files\ArcGIS\Desktop10.0\ArcToolbox\Toolboxes\Production Mapping Tools.tbx')

# set our workspace to an sde connection file
arcpy.env.workspace = "c:/data/SoCal.sde"

# fully qualified name to an ArcSDE feature class (dataset/feature class)
coastpath = "socal.GIS.SoCal/socal.GIS.CoastA"

# make a feature layer from islands in the CoastA feature class in the
# prod mapping sample data 
if arcpy.Exists("Coast") == False:
    arcpy.MakeFeatureLayer_management(coastpath,"Coast")

# select an island - verify that objectid 84 is an island in your data
arcpy.SelectLayerByAttribute_management("Coast","NEW_SELECTION","objectid=84")

checkoutDb = "c:/data/SoCalIslandTrees.gdb"

# make a new geodatabase
if arcpy.Exists(checkoutDb) == False:
    arcpy.CreateFileGDB_management("c:/data","SoCalIslandTrees.gdb")    

# another fully qualified ArcSDE name (dataset/feature class)
treespath="socal.GIS.SoCal/socal.GIS.TreesA"

# check out some data into the new file gdb
arcpy.CreateReplica_production(treespath,"CHECKOUT",checkoutDb,"islandTrees","TRUE","INTERSECTS","Coast")

# check the extension in
arcpy.CheckInExtension("Foundation")

CreateReplica example 2 (Python window)

This ArcGIS Python window example demonstrates how to use the CreateReplica tool with the ONE_WAY replica type. The script replicates production mapping SC_Index sample data from an Oracle instance to an SQL Server Instance.

sourceDb=r'c:\data\Socal_sample_oracle.sde\SOCAL_DATA.SC_Index'
targetDb=r'C:\data\SoCal.sde'
# import the production mapping toolbox - you may have to change this path
arcpy.ImportToolbox(r'C:\Program Files\ArcGIS\Desktop10.0\ArcToolbox\Toolboxes\Production Mapping Tools.tbx')
arcpy.CreateReplica_production(sourceDb,"ONE_WAY",targetDb,"indexRepl1","NO_FILTER_BY_GEOMETRY","INTERSECTS","")
