You got to explain why you don't want to use LIST UTILITIES. That is much more portable and reliable (consider DB2 process model changes between V8 and V9).
Anyway, I would assume that a db2agent executes RUNSTATS or other utilities. You can read up here on the DB2 processes for Version 8:

Note that this
has changed in V9 because DB2 moved to threaded engine.
