Parameter files in Informatica

Parameter file:

1. A parameter file is created by text editor.

2. In that, we can specify the folder and session name, then list the parameters and variables used in the session and assign each value.

3. Save the parameter file in any directory, load to the server on $informatica_home/PrmFiles

4. We can define following values in a parameter

a. Mapping parameter

b. Mapping variables

c. Session parameters

5. You can include parameter and variable information for more than one session in a single parameter file by creating separate sections, for each session with in the parameter file.

6. You can override the parameter file for sessions contained in a batch by using a batch parameter file. A batch parameter file has the same format as a session parameter file.
