Re: Will Upgrading to V4R5 impact performance???

Amen brother!

For a release upgrade I would go to the web site:
http://www-912.ibm.com/s_dir/sline003.NSF/GroupPTFs?OpenView&view=GroupPTFs

And order any group ptf that might remotely apply to my 400.  At the bare
minimum:
Hipers, Database, Backup Recovery Solutions, Java, and your flavor of web
server.

And keep in mind, just like ordering SF99450 or SF99510 these are subject
to change.  Sometimes weekly.  Example, SF99105 may contain different PTF's
from week to week.  So just because you've applied SF99105 a year ago
doesn't mean you don't have to reapply it from a more recent copy.

                    Please respond to

in the V4r5 preventive service plan (psp) SF98450 is the following:

   4. 00/10/11 To prevent possible query performance problems after
               installing Version 4 Release 5.0, perform the following:
               1.  Order Database Group PTF SF99105 and have the CD
                   available BEFORE the upgrade.
               2.  Apply Database Group PTF SF99105 immediately after
                   applying the latest cumulative PTF package.

  10. 01/06/04 DB2 Universal Database (UDB) for iSeries contains
               join query performance enhancements.  Refer to
               Information APAR II12888 for additional information.

   I would not load v4r5 without #4 above.
Are you having query problems after loading SF99105? This warning in psp
since Oct/2000.
Also would not load a release without reading the PSP (and am not saying
you
didn't, but as a warning to others).
This same warning to anyone who received a v4r5 pre-loaded system.
I did 2 different v4r5 upgrades last weekend for 2 diff companies - no
problems.
