Tables Area: User Spool Space Requirements
Whenever you create a new user, reserve a minimum of 20% of user permanent space for spool space. It is better to determine the optimum amount of space according to your application environment. This takes into account such factors as average table size, protection choices, number of rows involved in commonly used transactions, and so forth.
The optimum allocation depends on your application environment. If your requirement is to perform the calculations according to the formulas provided in this section, and the calculated amount exceeds 20% of permanent space, use the actual figure plus 5%. To determine an allowance based on your applications, use the formulas in this chapter.
