When running the Simple Connection Test Cobol you may encounter an error such as:

Interestingly, your gut should be saying you have the wrong PeopleTools COBOL being ran, and you’d be right.  In my case I had all the compiles done correctly, but I was working in a decoupled home environment, but the source for the application came from an old system where the Application home still had the COBOL source combined with application and tools code.  Once I removed the PT* cobols from the source and recompiled and moved the files around correctly, everything worked like a charm!
