Service configuration files
VPC: Release 9.3

The properties of service deployments are maintained in a file for each configuration in the GIS server's cfg directory(Each Service property is saved in a configuration file under the cfg directory of the GIS server, for example, c: \ Program Files \ ArcGIS \ Server \ User \ cfg \ zhyxk. mapserver. CFG). When you add a new service configuration to the GIS server, a new configuration file is automatically created(When you add a new service to the server, a new configuration file is automatically created). When a configuration is deleted, its configuration file is deleted from the cfg directory(When a service is deleted, its configuration file is also deleted automatically.).

The name of a service configuration file follows the pattern <configuration Name>. <service type>. cfg. For example, the map service Redlands wocould have the name Redlands. mapserver. cfg.

It's possible to add a configuration to the GIS server by manually creating a configuration file in the cfg directory, and it's possible to delete a configuration by deleting its file from the cfg directory. in both cases, the new or deleted configuration will not be recognized by the server until the Server Object Manager (SOM) is restarted. if the SOM encounters a specified upted configuration file, the SOM will log a warning and ignore the configuration.

If you edit a service configuration file manually, you must also restart the SOM for the changes to take effect(If you have edited the service configuration file, you must restart the SOM service to make the change take effect).

Ifeaturelayerdefinition
Interface

Provides access to Members that define a subset of the features from
Underlying feature class.Note:The ifeaturelayerdefinition interface has
Been superseded by ifeaturelayerdefinition2. please
Consider using the more recent version

Remarksuse this interface to set a definition query on a layer so that only
Features that meet the specified criteria are displayed (Use this interface to set a query on the layer to display features that meet the specified conditions. Featurelayer controls the display class of featureclass, while featureclass is the data source, which is the embodiment of shpfile in memory ). Use
Definitionexpression To access the definition query. Also, you can use Createselectionlayer To create a new
Featurelayer Based on an existing Featurelayer's Selected
Features. In the ArcMap user documentation and interface this new layer is
Called a selection layer.




You can useRelationshipclassTo access the relationship
Class, if one exists, that defines the relationship between the layer and
Table that is joined to it. This same object can be accessed through
Idisplayrelationshipclass: relationshipclass. idisplayrelationshipclass can be
More convenient because it has multiple additionl methods and properties
Working with layer joins.

Which type of query shocould I use? Three common interfaces for querying Geodatabase objects are the iqueryfilter, ispatialfilter, and iquerydef interfaces. Each one has different capabilities,
The following table shows:

Requirement	Iqueryfilter	Ispatialfilter	Iquerydef
Apply attribute Constraints	True	True	True
Apply Spatial Constraints	False	True	False
Query results contain fields from multiple tables	False	False	True
Query results returned as a cursor	True	True	True
Recordset objects can be created from results	True	True	True
Returned records can be edited	True	True	False

(The query result contains fields from multiple tables, that is, table join queries are supported)
