Re: 170 WITH BROKE LEG

All of KirkG's info is good, but the MAX/MIN Percent fields in the
shared pool definitions, along with the paging and priority settings
should be used so that no pool gets "starved" at the expense of another
pool.  Also, the machine pool should be about 25% of the total memory. 
Page faults in the machine pool are KILLERS!  BTW, how many disks do you
have? How much memory?  If you have 64 meg and 1 disk, there isn't a
whole lot you can do to speed it up short of buying memory and disk. 
You can mail me directly with your specifics if you would like and I'll
help if I can.
