Parameter File Structure

Parameter File Structure

A parameter file is an XML file that contains at least one parameter and its assigned value.
The Data Integration Service uses the hierarchy defined in the parameter file to identify parameters and their defined values. The hierarchy identifies the mapping or workflow that uses the parameter.
You define parameter values within a project or application top-level element. A project element defines parameter values to use when you run a specific
mapping
in the project. A project element also defines the parameter values to use when you run any
mapping
that uses the objects in the project.
An application element defines parameter values to use when you run a
mapping
in a specific deployed application. If you define the same parameter in a project top-level element and an application top-level element in the same parameter file, the parameter value defined in the application element takes precedence.
The Data Integration Service searches for parameter values in the following order:
  1. The value specified within an application element.
  2. The value specified within a project element.
  3. The parameter default value.
A parameter file must conform to the structure of the parameter file XML schema definition (XSD). If the parameter file does not conform to the schema definition, the Data Integration Service fails the
mapping
run.
On the machine that hosts the Developer tool, the parameter file XML schema definition appears in the following directory:
<Informatica Installation Directory>\clients\DeveloperClient\infacmd\plugins\ms\parameter_file_schema_1_0.xsd
On the machine that hosts Informatica Services, the parameter file XML schema definition appears in the following directory:
<Informatica Installation Directory>\isp\bin\plugins\ms\parameter_file_schema_1_0.xsd
