RE: Latest V4R2 Cum Tape -- MIDRANGE-L

 Although not for V4R2 there is a PTF out for V4R1 that "helps" the
installation on a CUMe CD during working hours.  MF17414 the abstract:
While running GO PTF option 7 or 8, or the APYPTF command to
apply ptfs for product 5769999 the user pool fault rate and cpu
utilization can be excessively high.  This can impact the
performance of a production workload running in parallel with
the ptf apply process.

Of course this is an IPL PTF.  I have noticed a big difference after
applying this PTF.  Of course you olny find this PTF (not on CUMe CD) after
throughly trashing response time a newly installed 640.  I caught @#$% for
that one.

When you load the cum package during the day, do a CHGJOB RUNPTY(55)
(or some reasonably high number, depending on whether you want to
protect both interactive and batch jobs from performance degradation)
before starting option #8 from the PTF menu.
