Parameter files

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.
You cannot use a parameter file if the mapping task is based on an
elastic mapping
.
You enter the parameter file name and location when you configure the task.
