Hello,
Was just looking for some pointers not a lecture,
If you believe that somewhere between your first 2 submissions there was a lecture, you will have a very frustrating time in IT (or anywhere else in the business world).
As i mentioned to Steve, this particular forum (ibmmainframeforum.com) is for students and other beginners. Capacity Planning (which is what you asked about) is not given to "newbies" - except as possibly a class exercise - and the "rules" are defined as part of the exercise.
When you post a question that is classwork or if you are simply curious, it is best to say so in the initial post. . . It can make a big difference as to who might respond as well as what kind of reply is posted.
There are some forums out there that are very friendly - unfortunately 1/2 to 3/4 of the technical replies are between questionable and simply incorrect. . . And an inexperienced person with a question will not know the difference.
And, yup, i guess this was a lecture. . .
Good luck,
d
