Today was a pretty slow day. I spent most of the day kicking back in the MVP room talking to the MVPs and the Microsoft folks. I did make it to a couple of sessions however.
Today was another excellent day here at PASS 2008 in rainy Seattle, WA.
The sessions from the first day of PASS were great.
Read on for info about a couple of the sessions.
For those of you lucky enough to make it to PASS, I’ll be seeing you at the Kick Off party tonight at the Welcome Reception in Room 6ABC at the event.
For those who aren’t able to make it, I’ll do my best to keep you up to date on the goings on at the event. There was decent coverage for WiFi last year, I’m assuming that there will be good WiFi coverage this year as well.
For those that weren’t aware, tonight is the Welcome receiption for the PASS Summit in Seattle Washington (the summit actually started on Monday for those who attended the Pre Summit Sessions).
I’ll post as often as I can during the summit.
The nice folks at the Inland Empire .NET User Group have invited me to come and speak to them. This is a great speaking opportunity for me as they are about 20 minutes from my house.
I won’t be speaking there until December 9, 2008 (it’s amazing just how far in advance some of this stuff gets scheduled).
I’ll be giving two presentations at the meeting. The first will be the ever popular Query Tuning, and the second will be a talk on the SQL Server 2008 Resource Governor. The address and directions to the meeting can be found on the IE .NET User Group web site. If you are going to attend there meetings they have an RSVP link on the site.
Microsoft has now released the the majority of the upgrade exams from SQL Server 2005 to SQL Server 2008.
Now, I know that this has absolutely nothing to do with SQL Server, and if you read slashdot this is probably going to be old news for you.
But apparently scientists have taken some pictures which show planets outside of the phones in our solar system.
Here’s a blog about it from BadAstronomy.
This article on Spiegel.de has some great images (it’s in German or Dutch or something) but they have an amazing overlay of images of one of the planets from a few years ago as well as the most recent position, including the track of the planet which I think is just an awsome image. This have another planetary system graphic which shows the HR 8799 system compared to our system (the defination is in English on this one).
If you run across any other images feel free to post links to them below.
Here’s another pic of the planet which orbits Fomalhaut with it’s position from 2004 and 2006.
This is just amazing stuff that we are seeing today.
MSDTC (aka Microsoft Distributed Transaction Control) is a piece of software which a lot of people use, but they don’t really know what it does, or how it works.
MSDTC is used by SQL Server and other applications when they want to make a distributed transaction between more than one machine. A distributed transaction is simple a transactions which spans between two or more machines. The basic concept is that machine 1 starts a transaction, and does some work. It then connects to machine 2 and does some work. The work on machine 2 fails, and is cancled. The work on machine 1 needs to then be rolled back.
DTC is for the most part a black box. It just sort of works without much interaction exept for the initial setup.
The only time that DTC needs to be used is when more than one physical computer is going to be involved in an explicet distributed transaction. If you are going from one instance to another on the same server DTC will not be needed. If you are going from one instance to another within a cluster you will want to have DTC available as you may have to go between nodes of the cluster as you have no guarantee that the instances will be on the same physical node.
I hope this helps explain DTC a little bit at least. If you have specific questions about DTC, feel free to post them below and I’ll try and find the answers for you.
I have just been informed that there will be a Lanch Party for the SQLServerPedia.com/Wiki website at PASS on Wednesday the 19th. If you will be attending PASS be sure to swing by Booth 414 (Quest Software’s booth) and pick up your party invite.
Details for the location are on the invite, so be sure and pick one up on Wednesday.
If you haven’t been able to make it to a party that Quest has put on in the past, they tend to go all out.
