Oracle OpenWorld 2007...

IMG_0466

I arrived last night, late.  I am doing a weeks worth of stuff in two days this year.  I've had a rehearsal, a podcast recorded and am waiting to do my first talk - at the Unconference (the no slide zone).  The first talk is "DBA 2.0", the role of the DBA in the year 2007 (and how it is a bit different from the way it was in 1997, 1987...)

Later this afternoon, a "meet and greet" session in the OTN lounge is on the schedule and then a customer meeting.  Tomorrow is the really busy day - a keynote session in the morning as part of the IDevelop 'sub conference', another "no slide zone" talk in the afternoon and then finishing up with a regular session that evening. 

Then, get on the plane to fly back home :)

So, what was the biggest surprise news so far?  Oracle VM...  I'm a huge fan of virtualization - have been for a long time.  This is going to be cool.

Any chance us less fortunate people will have access to see/hear your DBA 2.0 talk?

The surprise was - Tom was sporting a beard.

DBA 2.0 was a good show.

Looking forward to the 2 talks on Tuesday.

Very unhappy that I missed your dba2.0 talk. When I set up my schedule 2 weeks ago, I searched for all the sessions that you would speak at and that talk did not show up. I signed up for the 11 new features and couldn't get into the oracle develop session. Like Don asked... is there a way to see/hear your dba 2.0 talk?

I’m curious how do reconcile your rule "one host one database instance" with VM feature "one host many operating systems"?

there is nothing to reconcile with the "one host, one instance"

the reason I say "one host, one instance" is because when you have two instances running on the same host - you stand zero chance of tuning either or. One instance - you stand a chance.

Hence virtualization is a nice extension of this - you have a host (the virtual machine) with its dedicated resources (memory and cpu) and it is as if you had a separate box.

I've never said you need a physical machine per server.

I've always said "one host, one instance".

And the VM is the host.

Does really VM dedicate all resources to many hosts installed on one physical server? And what about database critical I/O operations?

A VM environment permits you to give a certain amount of CPU to a VM, a certain amount of memory, and you can dedicate channels (IO paths) to each.

It gives you a chance to succeed. Without it - you don't have one.

that is all, yes, anything can be configured incorrectly. You could for example create a SAN environment whereby everyone uses the same stuff - that would not be "smart". Or you can carve up the san so each thing that needs it as a resource is protected from everyone else.

VM's give you that ability, without it - by running many instances on a single host, you have no such ability.
