One year ago we moved from Solaris 2.6 to 2.9 -- total PROD upgrade time 1
hour.

It was also a fresh install of the OS but we pre-build the /root disc ahead of
time.  From the ORACLE APPS side all that had to be done was relink of both
APPL_TOPs/ORACLE_HOMEs.

Hardware cost is irrelevant in comparison to maintenance and upgrade costs.

Exactly!  When sh$t hit the fan at 3AM who do you call?

This RAC business is just ridiculous.  Larry got upset with Sun over them going
with Siebel and made up a "solution" to "scale out" using Linux.

I can't believe how many people jumped on this wagon!  Putting up bunch of
hardware pieces from different vendors slapped together with interconnects in
front of ***ONE*** shared storage in place of ONE decent BOX from ONE
os/hardware vendor is just insane!  Don't they see that most of the contention
is with IO not CPU?!  This is just crazy.

Right on!
