Default Re: DB2 not using all processors

Check the following
dbm cfg
INTRA_PARALLEL ON
MAX_QUERYDEGREE -1 or ANY 0r 8
db cfg
DFT_DEGREE -1 or ANY or 8

Those parms. affect whether or not multiple cpus will be used and how many.
All the other parms. affect capacity management issues WHEN you are
using multiple cpus not how many.

Given that you have ESE installed, and you are licensed for, that
version can use as many processors as you will make available.
