Parameter files

A parameter file is a list of user-defined parameters and their associated values.

Use a parameter file to define values that you want to update without having to edit the task. You update the values in the parameter file instead of updating values in a task. The parameter values are applied when the task runs.

You can use a parameter file to define parameter values in the following tasks:

Mapping tasks: Define parameter values for connections in the following transformations:
Source
Target
Lookup
SQL
Define parameter values for objects in the following transformations:
Source
Target
Lookup
Also, define values for parameters in data filters, expressions, and lookup expressions.; Not all connectors support parameter files. To see if a connector supports runtime override of connections and data objects, see the help for the appropriate connector.
Synchronization tasks: Define values for parameters in data filters, expressions, and lookup expressions.
PowerCenter tasks: Define values for parameters and variables in data filters, expressions, and lookup expressions.
