Data Processor Transformation Input Ports

When you create a Data Processor transformation, the Developer tool creates a default input port. When you define an additional input port in a Script startup component, the Developer tool creates an additional input port in the transformation.

The input type determines the type of data that the Data Integration Service passes to the Data Processor transformation. The input type determines whether the input is data or a source file path.

Configure one of the following input types:

Buffer: The Data Processor transformation receives rows of source data in the Input port. Use the buffer input type when you configure the transformation to receive data from a flat file or from an Informatica transformaton.
File: The Data Processor transformation receives the source file path in the Input port. The Data Processor startup component opens the source file. Use the file input type to parse binary files such as Microsoft Excel or Microsoft Word files. You can also use the File input type for large files that might require a lot of system memory to process with a buffer input port.

Service Parameter: The Data Processor transformation receives values to apply to variables in the service parameter ports. When you choose the variables to receive input data, the Developer tool creates a service parameter port for each variable.

Output_Filename: When you configure the default output port to return a file name instead of row data, the Developer tool creates an Output_Filename port. You can pass a file name to the Output_Filename port from a mapping.

When you define an input port you can define the location of the example input file for the port. An example input file is a small sample of the input file. Reference an example input file when you create Scripts. You also use the example input file when you test the transformation in the

Data Viewer

view. Define the example input file in the

Input Location

field.
