Chris,

Congratulations.  Is there any chance you could document the cost/benefit
analysis that went on to determine whether it made more sense to upgrade the
HP hardware and software versus going with Linux/390?  Any interest in you
doing a user experience session for SHARE?  :)

Subject: linux early results


In late 2000, the Oklahoma Department of Human Services decided that the HP
equipment purchased in 1995 to service the Child Welfare division needed to
be upgraded.  The assumption at that time was to continue with HP as the
primary vendor and the operating system would continue as HP-UX; however,
government being the way it is, the bidding invitation was not extended
until early 2002, with the bids arriving in April.  At that time a separate
project was underway to move our existing 390 hardware to z/Series.  IBM
then mentioned to management that Linux running on the z/Series might be of
benefit to us.  After much handwringing, mentions of security, and shouts
that Linux wasn't mature enough, we decided to go ahead with putting a
mission critical Oracle database on Linux under z/VM. (geek note: it's a
2064-1C5 with two engines dedicated to a z/VM lpar)

Fast forward two years.

On April 9, 2004, the child welfare database on HP-UX was put in read-only
mode.
On April 10, the import to Linux completed with minor (and correctable
issues).
On April 11, the go ahead to put the Oracle/Linux database in read/write was
given
On April 12, 2004, the first users began logging in (much sweating and
worrying on the part of certain sysadmins).  In first six hours, we have
received comments such as "... 'it is flying' and another was 'they must
have put another rat on the wheel'.  It is nice to see smiles!" and "Mondays
have always been the slowest of the days I've noticed in the past, but today
it is really nice.  The slowest transaction seems to be when you first sign
on to KIDS, but after that it is 'smooth sailing.'  Thanks!"

With the polls closed and early results coming in, Linux on z/Series looks
like the winner!
