Web Service Properties

Web Service Properties

The following table describes the web service properties:
Property
Description
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 greater than or equal to 0. 0 means that the Data Integration Service does not keep the DTM instance in memory. Default is 5000.
You can also set this property for each web service that is deployed to the Data Integration Service. If you set this property for a deployed web service, the value for the deployed web service overrides the value you set for the Data Integration Service.
Logical URL
Prefix for the WSDL URL if you use an external HTTP load balancer. For example,
http://loadbalancer:8080
The Data Integration Service requires an external HTTP load balancer to run a web service on a grid. If you run the Data Integration Service on a single node, you do not need to specify the logical URL.
Maximum Memory Per Request
The behavior of Maximum Memory Per Request depends on the following Data Integration Service configurations:
  • The service runs jobs in separate local or remote processes, or the service property Maximum Memory Size is 0 (default).
    Maximum Memory Per Request is the maximum amount of memory, in bytes, that the Data Integration Service can allocate to all transformations that use auto cache mode in a single request. The service allocates memory separately to transformations that have a specific cache size. The total memory used by the request can exceed the value of Maximum Memory Per Request.
  • The service runs jobs in the Data Integration Service process, and the service property Maximum Memory Size is greater than 0.
    Maximum Memory Per Request is the maximum amount of memory, in bytes, that the Data Integration Service can allocate to a single request. The total memory used by the request cannot exceed the value of Maximum Memory Per Request.
Default is 50,000,000.
Skip Log Files
Prevents the Data Integration Service from generating log files when the web service request completes successfully and the tracing level is set to INFO or higher. Default is false.
