EMC World 2008 Day 1 (The first post)

Published On: 2008-05-19By:

While waiting for the first keynote to start I figured that this would be as good a time as any to write a quick post.

 I just got out of the first session of the morning.  I decided to catch the VMware VI3 session which went over the new features of ESX 3.5.

 It was a very good session packed with great info about the new features of VMware ESX 3.5 which came out a few months ago.

3.5 introduces the Storage Vmotion.  It’s similar to the regular Vmotion which moves VMs from one host to another, but it’s designed to move a VMs storage from one disk (LUN, array, etc) to another disk within the same host without taking the VM down.  In prior versions of VMware to move a VM from on disk to another you would need to power the machine down and then move the machine.  It can now be done as a live operation.  It does temporally double the memory and CPU requirements of the guest OS, and it is a CPU and disk intensive operation and should be done off hours, but it’s a great way to move from a full disk to an empty one.

 Another great technology which I was introduced to is the VDM or Virtual Desktop Manager.  As I understand this technology it allows you to take a single Windows XP guest OS, and allow many people to connect to it.  The VDM places a connect pool in front of the Windows XP guest OS and as people connect to it, it takes a snap of the guest OS, and lets the new user use the snap.  This allows many people to use a single Virtual Machine without increasing the amount of disk space required, and reducing the IO requirement of your Windows XP (or Vista) guests on the host.

As the Keynotes proceed I’ll try and go over what they are talking about.

EMC World 2008 Day 0

Published On: By:

Today is the check-in and welcome party for EMC World.  EMC and Brocade had the Goo Goo Dolls perform at the welcome party.  The party and show were fantastic.

Funniest comment of the concert would have to be “This is the first all you can eat buffet rock show I’ve ever been to.”

The video was taken by my wife (who also had a great time, thanks for coming with me).  What you don’t see (but you can here) is John Rzeznik talking to one of the people serving the food about 2 feet from the front of the stage.  If anyone has better shots or video please post them and links to them.

Here are some stills which my wife took. She takes all the photos. I can’t take a picture to save my life.  (Click the image to see the bigger version.)

Back To Basics: Service Broker Message Types

Published On: 2008-05-15By:

The message type is the first of the service broker specific objects.  The message type defines the name of the message, and performs any validation that the service broker needs to do on the contents of the message prior to sending the message.  If the message is being sent to another database (on the same server or a different server) then the message type must exist on both databases.

Validation can be one of four options.

  1. None (My personal favorate especially for sample code)
  2. Empty
  3. Well_Formed_XML
  4. Valid_XML With Schema Collection

1 and 2 are pretty straight forward.  None = No validation is done.  Empty = The message must be empty.  Well_Formed_XML requires that the XML be a valid XML document.  The fourth option requires that not only the XML be valid, but that it fits within a pre-existing XML schema collection (an XSD which has been loaded into the SQL Server).

The syntax to create a Message Type is pretty basic.

CREATE MESSAGE TYPE [MessageTypeName]
VALIDATION = NONE

That’s it.  If you need to change the schema use the AUTHORIZATION clause to set the owner of the object.

When using the validation of NONE it is up to the receiving code or application to verify that the data within the message exists and is valid.

Any other DBAs brave enough to go to EMC World?

Published On: 2008-05-14By:

Next week I’ll be stepping into the lion’s den of sorts.  I’ll be off to Las Vegas to attend EMC World.  I went last year, and I’m pretty sure that I was about the only full time DBA there.  The storage folks treated me pretty nice, even after they found out that I was a DBA.

Hopefully when I get back I’ll have all sorts of new storage tips and tricks to share with everyone.

If anyone else if brave enough to attend let me know here.  Maybe we can meet up at one of the events.
