The following service level parameters can be configured when sharing a web layer using ArcGIS AllSource. Because these parameters are stored at the service level, when sharing multiple web layers, such as a map image layer with an associated web feature layer, these parameters are only set once and shared by both web layers. For more information about the relationship between a web layer and a service, see Understanding services, layers, and maps.
Service parameters available
Depending on your active portal and which layer types you selected, different parameters are available.
The workflow for setting service parameters for each type of web layer are different and are not discussed in detail here. Each web layer type has its own configuration topic you can refer to for more information:
| Parameter | Description |
|---|---|
Maximum records returned by server | Clients, such as the ArcGIS Web APIs, can perform query operations to return specific information, or records, from a web layer. This property specifies how many records can be returned by the server to a client for any given query operation. Specifying a large number of records to be returned by the server can slow the performance of client applications consuming your web layer, such as web browsers, and your GIS server. The default value is 2,000. This parameter is available when sharing the following:
|
Max number of coded domains | An integer representing the maximum number of domain codes that can be returned from all fields, subtypes, layers, and tables in a map image layer. In a large multiuser map service, the number of domain codes returned by the service may exceed the default value. If this occurs, the service continues to run normally, but the map service drops all domains to maintain server performance. Additionally, an error documenting the event is recorded in the server logs. If you require the map service to return a greater number of domain codes than the default value, specify the value. Note that the performance of the service may be affected when it must return more than 25,000 domain codes. The default value is 25,000. This parameter is available when sharing the following:
|
Max image height | An integer representing the maximum height (in pixels) of images the map service will export. The default value is 4,096. This parameter is available when sharing the following:
|
Max image width | An integer representing the maximum width (in pixels) of images the map service will export. The default value is 4,096. This parameter is available when sharing the following:
|
Max sample size | An integer representing the maximum number of records that will be sampled when computing a class breaks renderer. The default value is 100,000. This parameter is available when sharing the following:
|
Enable schema locking | This property determines whether the map service acquires schema locks for map layers that come from referenced datasets. By default, this property is enabled on enterprise database data, shapefiles, and coverages. Locks are not placed on file geodatabases. This parameter is available when sharing the following:
|
Disable identify relates | This property determines whether the map service returns information about features from related tables and feature classes when you perform an identify operation. By default, this property is not checked so the identify operation returns related information. This parameter is available when sharing the following:
|
Time zone of the data | If one of the layers you are sharing contains date fields that contain dates stored in a local time zone, such as eastern standard time, specify the time zone in which the dates are recorded. This allows the service to correctly convert date and time values when you interact with the service. If you do not specify a time zone, the dates will be assumed to be stored in UTC. You must specify the time zone if your data has editor tracking enabled and uses database time. The default value is None (Assumed UTC). If you are sharing a map image layer to ArcGIS Enterprise 10.9 or later, choose Unknown if your map contains layers with date fields that do not have a known time zone or if multiple time zones are represented in the data. Unknown time zones do not apply to editor tracking date fields. Editor tracking date fields are in UTC even when the service's time is set to unknown. This parameter is available when sharing the following:
|
Preferred time zone for display | ArcGIS AllSource will display date fields in the preferred time zone when you interact with the web layer. Date fields will be displayed in UTC if no preferred time zone is specified. This parameter is available when sharing the following if a time zone other than None (Assumed UTC) or Unknown is selected:
|
Adjust For Daylight Saving | If you specify a time zone other than UTC and you want the time zone or preferred time zone to account for daylight saving time, check this property. The default value is not checked. This parameter is available when sharing the following:
