A parameter file is
a list of user-defined parameters and their associated values. Use a parameter file to
define values for input parameters and in-out parameters across one or more
tasks.
Use a parameter file to define parameter values that you want to update without having to edit
the task.
You can create a parameter file using one of the following methods:
Use a text editor such as Notepad to create a
parameter file from scratch.
For
mapping
tasks, download
a parameter file template from the
Runtime Options
page.
You can use a separate parameter file for each task or maintain a single parameter file with
section headings that tell
Data Integration
the scope of each parameter value.
Depending on the task type, you save the parameter file on a local machine or in a cloud hosted
directory. You specify the parameter file name and directory when you configure the
task.
Data Integration
reads
the parameter file at the start of each task run and applies the parameter values.
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.
Data transfer
tasks
Define values for parameters in data filters, expressions, and lookup
expressions.
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 can't use a parameter file in a mapping task that is based on a mapping in SQL ELT
mode.
