Web Service Properties

REST web service and SOAP web service properties include read-only general properties and properties that the Data Integration Service uses when it runs a web service.

When you expand a web service or a REST web service in the top panel of the Applications view, you can access web service operations or resource in the web service.

The Applications view displays read-only general properties for the web services, web service operations, or web services resources. Properties that appear in the view depend on the object type.

The following table describes the read-only general properties for each type of web service and the web service operations or resources:

Property	Description
Name	Name of the selected object. Appears for all objects.
Description	Short description of the selected object. Appears for all objects.
Type	Type of the selected object. Appears for all object types.
Location	The location of the selected object. This includes the domain and Data Integration Service name. Appears for all objects.
URL	URL used to connect to the web service. Appears for web services.

The following table describes the configurable web service properties for web services:

Property	Description
Startup Type	Determines whether the web service is enabled to run when the application starts or when you start the web service.
Trace Level	Level of error messages written to the run-time web service log. Choose one of the following message levels: OFF. The DTM process does not write messages to the web service run-time logs. SEVERE. SEVERE messages include errors that might cause the web service to stop running. WARNING. WARNING messages include recoverable failures or warnings. The DTM process writes WARNING and SEVERE messages to the web service run-time log. INFO. INFO messages include web service status messages. The DTM process writes INFO, WARNING and SEVERE messages to the web service run-time log. FINE. FINE messages include data processing errors for the web service request. The DTM process writes FINE, INFO, WARNING and SEVERE messages to the web service run-time log. FINEST. FINEST message are used for debugging. The DTM process writes FINEST, FINE, INFO, WARNING and SEVERE messages to the web service run-time log. ALL. The DTM process writes FINEST, FINE, INFO, WARNING and SEVERE messages to the web service run-time log. Default is INFO.
Request Timeout	Maximum number of milliseconds that the Data Integration Service runs an operation mapping before the web service request times out. Default is 3,600,000.
Maximum Concurrent Requests	Maximum number of requests that a web service can process at one time. Default is 10.
Sort Order	Sort order that the Data Integration Service to sort and compare data when running in Unicode mode.
Enable Transport Layer Security	Indicates that the web service must use HTTPS. If the Data Integration Service is not configured to use HTTPS, the web service will not start.

The following table contains properties unique to REST web services:

Property	Description
Is Authentication Required	Enables basic authentication for the REST web service. Basic authentication requires a user name and a password from web service requests. Default is disabled.
Input Precision	Maximum number of characters that the Data Integration Service parses in the request message. The web service request fails when the request message exceeds the input precision. Default is 10,000.
Output Precision	Maximum number of characters that the Data Integration Service generates for the response message. The Data Integration Service truncates the response message when the response message exceeds the output precision. Default is 3,000.

The following table contains properties unique to SOAP web services:

Property	Description
Enable WS-Security	Enables the Data Integration Service to validate the user credentials and verify that the user has permission to run each web service operation. SOAP web services only.
Optimization Level	The optimizer level that the Data Integration Service applies to the object. Enter the numeric value that is associated with the optimizer level that you want to configure. You can enter one of the following numeric values: 0. The Data Integration Service does not apply optimization. 1. The Data Integration Service applies the early projection optimization method. 2. The Data Integration Service applies the early projection, early selection, push-into, and predicate optimization methods. 3. The Data Integration Service applies the cost-based, early projection, early selection, push-into, predicate, and semi-join optimization methods.
DTM Keep Alive Time	Number of milliseconds that the DTM instance stays open after it completes the last request. Web service requests that are issued against the same operation can reuse the open instance. Use the keep alive time to increase performance when the time required to process the request is small compared to the initialization time for the DTM instance. If the request fails, the DTM instance terminates. Must be an integer. A negative integer value means that the DTM Keep Alive Time for the Data Integration Service is used. 0 means that the Data Integration Service does not keep the DTM instance in memory. Default is -1.
SOAP Output Precision	Maximum number of characters that the Data Integration Service generates for the response message. The Data Integration Service truncates the response message when the response message exceeds the SOAP output precision. Default is 200,000.
SOAP Input Precision	Maximum number of characters that the Data Integration Service parses in the request message. The web service request fails when the request message exceeds the SOAP input precision. Default is 200,000.
