Can you provide some references to lack of support of read-consistency. Not
that I don't believe you but I just read that to a guy next to me and he is
clamoring for evidence. - E

Privilege ? Reality? Reality and MS is an oxymoron.
I've had the fortune (misfortune) to become a SQL Server DBA
in addition to my Oracle duties, due to packaged application
requirements. As an admitted defiler of all MS stands for and
it's dubious accomplishments, I'll offer a few grains of sand,
most of which you might be advised to take up with management
away from the MS marketing morons.
First, be aware that MS pricing is not nearly as inexpensive
as their hype would have you believe, once you remember that they
have always charged for upgrades, their discounts aren't usually
as steep, and support... well, what there is of it s****. I've
spent 3 calls at $245.00 each only to be told each time the
answer was to 'reboot'. This on W2K/SS2K fail-over cluster,
with many of their best support people contributing to this
non-solution.
On a technical note: Virtually every one of their new speed
marks of note have been done on multi-server clusters; Oracle
still holds most single-server benchmarks. Additionally, their
application benchmarks have no relationship to real world, as
even their SAP benchmark was done on a modified SAP installation
not available in 'ordinary' SAP applications.
The overhead of multi-server/cluster management makes their
scalability arguments, even if they could be accommodated by
existing software, moot.
Self-Tuning - Bah, Humbug. I've had the opportunity to see
some server code from SAP, PeopleSoft and Commerce One designed
for SQL Server. Guess what ? The real stuff, that which has to
perform, is often hinted (statements like
'option (loop join , force order, maxdop 1 )' which is pretty
much self explanatory; 'maxdop 1' = Oracle's noparallel.)
Then there's the entire discussion of read-consistency, which
SQL Server doesn't support. A whole thread there, and one
reason why SQL Server can be very quick in some operations: No
RBS to support. Everything is done from the transaction logs.
And then there's functionality...
Just my 2 cents...
