Chris - great job - terrific news.

Can you share some more:

1) how many linux instances are you running?

2) how much real memory do you have?

3) how much virtual memory are you allocating per linux instance?

And anything else you think would be worth knowing for those of us who are
planning and hope to match your success.

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!
