I've started getting into doing a bit of development with Informatica on our OBIA install (for reference, we are using OBIA 7.9.6.3 + Extension pack). Part of the "best practices" setup by our Oracle Consultant was to create a separate sandbox folder anytime we were making a change to an Infomratica mapping. The difficulty I had was how to test the workflow after I made my changes, as I can't run my change via DAC, without creating a separate execution plan, and I can't test directly in Infomratica, as it references a parameter file that exists on the server.
The solution was to extract the command that DAC would run (pmcmd), create a temporary parameter file, and then run my new mapping from my sandbox folder. And as always, I've created a helpful script to automate this!
Continue on to read for an explanation of what my script does, and a copy of said script.
