Configuring the Properties Tab

Configuring the Properties Tab

The HTTP transformation is built using the Custom transformation. Some Custom transformation properties do not apply to the HTTP transformation or are not configurable.
The following table describes the HTTP transformation properties that you can configure:
Option
Description
Runtime Location
Location that contains the DLL or shared library. Default is $PMExtProcDir. Enter a path relative to the Integration Service node that runs the HTTP transformation session.
If this property is blank, the Integration Service uses the environment variable defined on the Integration Service to locate the DLL or shared library.
You must copy all DLLs or shared libraries to the runtime location or to the environment variable defined on the Integration Service node. The Integration Service fails to load the procedure when it cannot locate the DLL, shared library, or a referenced file.
Tracing Level
Amount of detail displayed in the session log for this transformation. Default is Normal.
Is Partitionable
Indicates if you can create multiple partitions in a pipeline that uses this transformation:
  • No. The transformation cannot be partitioned. The transformation and other transformations in the same pipeline are limited to one partition.
  • Locally. The transformation can be partitioned, but the Integration Service must run all partitions in the pipeline on the same node. Choose Local when different partitions of the Custom transformation must share objects in memory.
  • Across Grid. The transformation can be partitioned, and the Integration Service can distribute each partition to different nodes.
Default is No.
Output is Repeatable
Indicates if the order of the output data is consistent between session runs.
  • Never. The order of the output data is inconsistent between session runs.
  • Based On Input Order. The output order is consistent between session runs when the input data order is consistent between session runs.
  • Always. The order of the output data is consistent between session runs even if the order of the input data is inconsistent between session runs.
Default is Based on Input Order.
Requires Single Thread Per Partition
Indicates if the Integration Service processes each partition at the procedure with one thread.
Output is Deterministic
Indicates whether the transformation generates consistent output data between session runs. Enable this property to perform recovery on sessions that use this transformation. Default is enabled.
If you configure a transformation as repeatable and deterministic, it is your responsibility to ensure that the data is repeatable and deterministic. If you try to recover a session with transformations that do not produce the same data between the session and the recovery, the recovery process can result in corrupted data.
