User exists in MP ondemand

[rajeshmutha]

Hi,
I'm very new to user exits concept. We have never used exists. 
How to user exit for below scenarios....I'm looking for list of steps that may have involved.

*****
Say I've a file test1.AFP which i need to load into test app. grp which has test1 and test2 applications with in it. Also i wanted to make some custom logging into my own file "/tmp/test_exit.log".
*****
How to handle this with exits?
How to invoke exit while running arsload program? I've enabled logging in system parameters dialog box.
Any help in this is highly appreciated.

These are the minimal things that i know.
  1. IBM provides a exit /usr/lpp/bin/arslog which can be used for custom logging
  2. Code related to user exists should go into /usr/lpp/ars/bin/exits

My platform details:
CMOD 8.4.1.2 On AIX 5.3

What type of information are you trying to collect?  It might exist in places where it's easier to find -- like the System Log or the new Load Log.

Yes JD. I just gave an example. All I want to find is how to write some business logic using exits.
