You're right, if you don't specify the number then DB2 will start assigning
port numbers at 50000 and go up by two for each instance on that server
(50002,50004, ...)
Your problem is that the behavior is identical on each server.  So every
instance on each server uses the same scheme.  Granted, the ip address is
different for each box but using defaults may lead to confusion.
The other exposure you have is: If you have people who are capable of wiping
out SERVICES files before notifying others, they will also be capable of
assigning port numbers 50000 and up to other applications.  Remeber, if you
don't specify, the numbers don't appear in the services file and therefore
will seem to be "free".
I'd keep a copy of the services filein a DB2 directory that others can't
touch.  That way, you could restore it without too much problems.
