Create Replica (Production Mapping)

サマリ

A replica is a copy of an enterprise geodatabase dataset. You can work independently with replicas and synchronize changes with the data's original geodatabase.

This tool creates a replica in a personal, file, or enterprise geodatabase from a specified list of feature classes, layers, datasets, or tables. Optionally, you can 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 to use a selected feature in another feature layer as an area of interest for replicated features. Any features from Replica Datasets with the USE_FILTERS option that intersect or are contained by the selected feature in Filter Feature Layer will be replicated to the Child Workspace.

• 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 checkout 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.

• Related data is replicated by default. To avoid replicating related data, you must specify each relationship class that defines the related objects you want to exclude using the Exclude Relationship Classes parameter.

• Related data is replicated in a forward direction, from origin to destination.

パラメータ	説明	データ タイプ
in_datasets	Value table of rows that contain a dataset to replicate and a filter option for that dataset. Specifying a filter option allows you to control how rows are replicated per dataset. Filter options include the following: USE_FILTERS —If in_usefilter is set to FILTER_BY_GEOMETRY, the tool replicates features that either intersect or are contained by in_features. SCHEMA_ONLY —Replicate the schema of the dataset to in_childworkspace. ALL_ROWS —Replicate all rows of the dataset to in_childworkspace.	Value Table
in_replicatype	The type of replica to create: CHECKOUT —Create a replica in which the changes can be checked back in to the parent geodatabase from the child. This is the default. ONE_WAY —Create 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 —Create 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 will contain the replicated data.	File; GeoDataServer; Workspace
in_replicaname	The name of the replica you create.	String
in_reuse_schema (オプション)	Indicates whether to reuse the schema of existing data in the in_childworkspace. This option can reduce the time required to replicate data by not re-creating existing schemas in the in_childworkspace. The in_reuse_schema is most efficient when used to replicate data into empty schemas in the in_childworkspace. This option is only available for checkout 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 in_features. Only applied to in_datasets that have the USE_FILTERS option. FILTER_BY_GEOMETRY —Apply the filter set in the in_filtertype. You must set in_filtertype and in_features. NO_FILTER_BY_GEOMETRY —Do 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 the in_features. This is the default. CONTAINS —Extract features from the 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
in_access_type (オプション)	Indicates the feature information model type to replicate. Model type specifies either simple or complex features. FULL —Replicate complex types (topologies and geometric networks) to complex types in the in_childworkspace. This option requires versioned data. This is the default. SIMPLE —Replicate all data, including complex types, to simple types in the in_childworkspace. The data on the child is not versioned if replicated to an ArcSDE geodatabase. This allows the replica to be interoperable with simple feature viewers and editors that are not based on the ArcGIS engine.	String
in_use_archiving (オプション)	Specifies whether to use the archive class to track changes instead of using the versioning delta tables. This is only available for one-way replicas. The in_replicatype must be created from the DEFAULT version. ARCHIVING —Use archiving to track changes. NO_ARCHIVING —Do not use archiving to track changes. This is the default.	Boolean
in_exclude_rel_classes [in_exclude_rel_classes,...] (オプション)	The list of relationship classes whose relationships you want to exclude from replication. The relationship classes will still be included if both datasets that participate are present, but the related objects are not replicated.	Relationship Class

    arcpy.MakeFeatureLayer_management(filterFeatureClass,filterFeature)

# select one feature from the feature layer
arcpy.SelectLayerByAttribute_management(filterFeature,selectType,filterWhere)

# make a new geodatabase for the replica gdb
