Example 5:

ENGINES CP,CP,AP,IP

MAXCPU 6

NUMCPU 6

The first four engines are defined with their specified type and are taken online. The next two CPUs are
defined per default as type CP, because the number in MAXCPU exceeds the number of CPUs in the
ENGINES statement. These additional two CPUs are also taken online through the NUMCPU statement.

Example 6:

ENGINES CP,CP,AP,IP

MAXCPU 6

NUMCPU 8

This configuration leads to an error. While the first four CPUs would be taken online with their specified
types and the next two CPUs would be of type CP per default and be taken offline, the excess engines
from NUMCPU compared against MAXCPU lead to an error message and a failing configuration.
