Uninstalling Yukon CTPs

OK, I realize that this can't be a perfect world, but why MS can't make a simple uninstaller that actually does what it's supposed to is beyond me. I have uninstalled Yukon Sept CTP on several boxes and always in the exact same order. Sometimes it works, sometimes it doesn't. Whenever it doesn't work, it leaves you unable to install RTM.
The usual fix for this is to reinstall the CTP, and uninstall it again. This for some reason manages to uninstall all the pieces that were left behind before. And of course, RTM doesn't provide an uninstall wizard so you can't use that.

One problem I recently ran across was that I wasn't able to install RTM, or reinstall CTP. The install for CTP said it had incompatible components and couldn't install. But the uninstall wizard said that there were no components to clean up. So now there's nothing left to do but uninstall manually.

But how do you know what to uninstall? The answer came to me from Donald Farmer at MS.

When you get this situation, check the log file under C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Files
What you want is the *_Core.log. They should all have pretty much the same info in them as the same components are probably failing all the time.

Reading the log, you will find a reference to the CLSID (a guid) of the component that setup “thinks” is installed.

Here's a clip from mine.
Product "{982DB00A-9C4E-436B-8707-18E113BAA44C}" versioned 9.00.951 is not compatible with current builds of SQL Server.Expected at least version: 9.00.1399.06
The Product Name is ""
Product "{90032DD0-ABEE-4424-AC1E-B076BDD4E350}" versioned 9.00.852 is not compatible with current builds of SQL Server.Expected at least version: 9.00.1399.06
The Product Name is ""
Loaded DLL:C:\WINDOWS\system32\msi.dll Version:3.1.4000.2435
Error: Action "PerformSCCAction2" threw an exception during execution.
Return Code: 70032

Copy that guid to clipboard, search for it in the registry and purge the registry of every reference to it. Just highlight that long GUID inside the curly brackets, and you should be ok. I included the brackets in mine, but I haven't tested without it... though again, it should be ok.

I've seen one instance where this didn't clear it up either. It left a bunch of .manifest files in there I think. I'd have to check to be sure, but just delete everything in that same log folder and try again. That should work for you this time.

In the future, I sincerely hope that instead of just doing a check for incompatible components, they actually delete the entries as well. That would be really helpful.

The Rant To Beat ALL Rants

This week I want to talk about what's been happening recently on SSC. As probably most of you know, I wrote the first in a series of articles on interviewing. In case you haven't heard of it, you can read it here.

During the discussion on this article, some of you said it must have been a joke, while others reverted back to the dark ages and performed a modern version of the Inquisition. I'll get to how I feel about that in a minute, but first I want to explain what the article was all about.

I wanted to say this so many times during the discussion, but I really wanted to see how far it would go... and originally, I was going to come clean in the 2nd installment, but I just don't think it can wait.
Let me say first off that this was a very carefully crafted piece. Didn't any of you catch onto the fact that the article was called "How to Mess Up an Interview"... GET IT?? I messed up the interview... (actually, one guy did get it... thanks, Paul, and while I think genius may be stretching it, I appreciate the vote of confidence.)

I've always had a flare for the dramatic, and when I conceived this series I had one thought in mind and that was to really drive the point home. So what I decided to do in this first installment was to give the readers just a little something to show them the kinds of things that can start out innocently enough but then completely blow an interview. The published draft of the piece was probably my 7th rewrite. Believe it or not, I actually got the idea from one of the worst interviews I ever had the pleasure to conduct. This guy went off on how dumb his current employer was, and how he was the only one there who knew anything at all. In the course of answering a question about the biggest disaster he had ever been a part of, he had a few choice things to say about the people he worked with including referring to the NOC guy as a stupid N-word... 3 TIMES!!!
When I asked him about his team and how they work together, he referred to his fellow DBAs as Jesus freaks who would just assume hold hands around the server and sing Kumbaya than to actually learn anything to actually fix the problem. It amazes me sometimes the lengths people will go to keep you from hiring them.

So anyway, I wanted to write this first installment in a way that would completely fail an interview. I started with that guy's interview as a model, but I had to be more subtle. There's no way I could possibly say the things he said, so I wrote one draft after another trying to tone it down to not only something believable, but something that would get my point across. In other words, I wanted to be that guy you wouldn't hire because he's just a little too... off, I guess.

The point of that first piece was to show that regardless of what you have to say, if you say it wrong, nobody will listen. There was some good solid advice in that first installment, but many of you refused to even see it because of the way it was presented.

Some of you weren't offended at all. You are my main audience. Others just didn't listen because they didn't like the way it was presented, but they kept their professionalism and just stated that they disapproved and went on about their business. You are also my audience. However, the hardcore zealots out there who not only denounced me and my writing, but also SSC as a whole, well, you are not my audience, and frankly, I'm ashamed to be in the same community with you. You embarrassed yourselves, and you embarrassed us all with your childish and petty behavior. Imagine professional people going on a public site and making a spectacle of yourselves like you did... and even cursing. You were so self-righteous, and smug, and proper, that you forgot how to conduct yourselves in public.

And for those of you who had Steve remove you from the list because of it... I say good riddance. If you're going to be that way we don't want you anyway, and you're only hurting yourselves. Personally, I enjoy getting my SSC newsletter every day, and there have been a lot of good articles. If you guys want to screw yourselves out of the knowledge you get from SSC because of one carefully-crafted piece, then you deserve what you get.

Well, let me just say that I've proven my point.

I did get a lot of support privately though. Many of you wrote me to express your support. I want to thank each and every one of you who did that. And those of you who supported me publicly, I thank you too. I didn't think anything I said was offensive either, but apparently, that's the kind of thing you can't dictate.

That's fine though... you guys turned a simple article into some kind of holy war and gay-bashing party.

And by the way... that gay thing really wasn't a slam on homosexuals. It's just an idiom that some people use. You know, like those other literal idioms like 'pulling your leg', 'heart of gold', 'broken heart', 'be an a-hole', 'look a gift horse in the mouth', etc. And the point of putting in the piece was to show you in the next installment that you have to re-train yourself to not use common phrases that could possibly offend. I got called down at work once for using the phrase 'partners in crime'. You just never know what will set somebody off (evidently).

So now it's up to you guys... do you want to see the rest of the series or not???
I await your response.

Stone Age DBAs

This rant is something very close to my heart. One of the things that really gets to me is the hours production DBAs are expected to work without any of the benefits that come with it. We're constantly being asked to get up in the middle of the night working on problems, and on those nights we do get to sleep we've been up very late rewriting code, or reviewing indexes, etc. On average I would say that most real production DBAs get about 4-5hrs of sleep a night. And by 'real production DBAs' I mean those in really busy shops, it has nothing to do with skill level.

So with all this outside work what do we have to show for it? We get to be in the office 9-6 every day as well. In almost every job I've had I've been expected to keep full office hours as well as work almost a full shift outside as well as be on-call 24/7. That includes holidays too because more often than not, the users aren't going to be working on the holidays so the company expects that to be the perfect time for me to come in and perform an upgrade without having to pull extra downtime. And of course, I can't do it from home over VPN, I have to actually come into the office and leave my family to sit in the server room.

What really gets to me is that these are companies that have full VPN access. There's no excuse for me to have to come into the office to do something I can do just as easily from home. I've had it out with so many IT managers and they just can't get around the old American mindset that the only work that can be done has to be done in the office. Technology should be freeing us from such archaic thinking, but it hasn't effected us as of yet. There are still plenty of companies out there who think you have to be in the office to be effective, when the exact opposite is true. If you actually pay attention to how many people come up to your desk to interrupt your work, and how many times you stand around and talk to someone about complete B.S. for 20mins at a shot, you'll find that spending a little quality time alone with your work at home will be a welcome change.

The whole thing is really a huge contradiction anyway. My last boss used to work from home when he wanted to really buckle down because the office was too distracting. When we requested the same thing he said there was no reason for us to be out of the office to do our jobs. He actually said and I quote: "People work 9-6 in America." and "VPN is designed to be used after hours so you can work more than your 8hrs, and so that you don't have to come in in the middle of the night when there are problems." What a serious load of CRAP!! Another reason they like to give is that people in other departments will want to start working from home if they let us, and they can't get that kind of thing started. My answer is usually the same thing... well, the users in payroll don't get called in the mniddle of the night and have to get up and look at systems for hours at a time. And the next time one of them complains that they should get to work from home because I do, just tell them that would be fine, but next time I get a call in the mniddle of the night, I'll call you and make you get out of bed too... because if I have to be up, you have to be up. Sure, other departments have to come into the office all the time, but quite often they've got jobs that either can't be done from home, or their job stops after business hours. They get to go home and forget work.

The life of a production DBA is different. Being always on call forces us to do things differently. We can never go to a baseball game or a movie or even a family gathering where they can be out of reach. We can get called away from our plans on a moments notice. I don't know the last time I saw an HR emergency that called the benefits girl out of a movie or woke her up in the middle of the night. It just doesn't happen.

As a reward for this level of service, we should be allowed to pretty much come and go as we please. If we need to work from home for a couple days that should be ok. If we need to take off early most days, or take a half day, or whatever. I had to pay an extra $300/mo for childcare because my boss wouldn't let me get off in time to get my little girl after school... because people in America work until 6... period.

This is the kind of ridiculous thinking that's holding us back. It increases traffic, drives up your blood pressure, and wastes gas. It even costs the company money because they have to have space for everyone when they could use fewer cubes if they let people work from home a couple days a week someone else could be in your spot while you're not there.

My current job isn't like that at all. We've got so many remote sites and we do everything over the wire anyway, so being on the wire from home isn't any different than being on the wire in the office. As long as we do our work we'll be able to work wherever we like. I personally would never abuse my privilege because I don't want to lose it, but I also know the second I do, the party will be over and I'll be in the office every day without fail.

What do you guys think? What are your experiences and thoughts on this topic?

What Separates DBAs from Developers--Part II

I don't know if any of you remember last week's post where I talked about some of the bad code I've seen, and the reasons why many developers don't seem to ever learn their lessons. Well, the most amazing thing has happened that may just explain the whole mystery.

I was looking through my wife's copy of Redbook this week and ran across an article about autism. To make a long story short, the article states that autistic people quite often go into programming careers. That really explains a lot doesn't it? As it turns out, programmers are genetically predisposed to buying their underwear at K-Mart. OK-OK, I'm just giving you guys a hard time. I'm just kidding... but Redbook really did say that autistic people tend to go into programming. If you don't believe me check it out. It's in the Sept 2005 issue on pg 197.

Ok, onto some serious business. I wasn't going to write on this topic again, but there was such an overwhelming response last week, I thought some of you needed more time to get it out of your system. And while some of you had some good arguments, others of you went so far as to insult me personally, while still others of you left me with some really interesting grammar lessons. I really don't mind the insults though. I kind of expect it actually after a posting like that.

Now, I think some of you are confusing a rant blog for real life. Just because I come on here and rant about something doesn't mean that I don't have a teamwork attitude at work. In fact, I'm always the first one to turn on People's Court(yeah, yeah, time for Wapner) when our developers need help. I teach SQL classes to show them the right ways to write code, and even give them DOs and DON'Ts. It never makes any difference though. When they turn their code in it always looks the exact same way it did before. Go figure. But of course you have to have a teamwork attitude with everyone. How else would you ever get your job done?

One of you said that it was a training issue. This is quite true. Training is the key. The problem is in getting them to get the training. You can make them sit in a classroom but you can't make them care. And that doesn't mean that I think all devs are bad either. There are exceptions, and I've even met a couple.

I really don't expect everyone to know everything, or even most of everything. And I certainly don't know everything, nor do I claim to. I'm sure that the answers I give to a complicated problem are not only different from what someone like Kalen Delaney or Kim Tripp would give, they're different from the answers I'll be giving 5yrs from now. Just as they're different from the answers I gave 5yrs ago. The good news is that the SQL superstars go through the same thing. Their answers changed based off of their current level of experience.
What I do expect though is for some of the basics to rub off after a certain amount of time. I expect that devs would know not to hardcode index hints, or put a clustered index on description varchar(200). I would also expect that you wouldn't put extra indexes to speed up inserts, or put 4 indexes on a 2 column table. Yet these are all things I've seen numerous times.

Maybe we should all swallow our pride and concentrate more on getting the job done and less on pointing fingers. I think I have a solution though. Why not base a bonus structure on the quality of the code when it hits production? So, you've got a 3 month window. You start out with $500 as a bonus whenever you push a major release into production. Then, for every problem caused by something you coded, you lose a portion of your $500. So, the DBAs have to fix a horrible query, you lose $100. They have to take out an index hint, $50, etc. Now answer me honestly... how many developers do you think would learn to think in sets then? How many times do you think our advice would go ignored? How many of the lazy 'select *' queries do you think we'd see? Anyway, just a thought.

And the same goes for DBAs too. How about the same type of structure for the systems. How many times do you want to lose your bonus because you didn't back up a DB properly, or didn't test the restore? How much money do you want to lose because you did something stupid and brought the system down, or left the where clause off of a delete and killed the whole table?

The problem we have at my office is that the devs don't write good code, and the users have become to expect that SQL runs very slowly. A very good example comes from a conversation I had with one of the production managers last year. She called and said they were having trouble with the reports. They're taking a long time to come up. I said, ok, which report. She told me which one, and said that it was taking about 35mins to come up. I said, and how long does it usually take? She said... it usually comes up pretty fast. The normal time is about 25mins. After I fixed the immediate problem I looked into the queries themselves. Once I finished with them, they came up in less than a second. It's very easy for users to get used to DBs performing poorly. If it's never been a fast system they have nothing to compare it to. It's up to all of us to set their expectations. We had a problem last week with another bit of code in which they were complaining that it had gone from 4secs to over 2mins. One of my DBAs took the ticket, and told the customer that the performance was unacceptable. The customer said, yeah, I know, that's why I'm calling. It used to take 4secs. My DBA said, no I mean the 4secs is unacceptable. Let's get that time down.

OK, maybe next week I can finally talk about batch deletes like I promised last week. Until then, remember... K-Mart sucks.

What Separates DBAs from Developers?

This topic has been on my mind a lot lately. Exactly what is it about developers that makes them write such crappy code? I mean seriously guys... would it kill you to put just a little thought behind the code you write?
I'll get to a couple examples in a minute, but first I want to explore the reasons why there's such a difference in mentality.

I think part of the reason is because developers are quite often under such strict deadlines they just don't have time to explore a lot of options. More often than not, if the query works, then it's good enough. I can't tell you how many times I've heard a developer say "well, it worked just fine on my workstation". This is after having 50 instances of their query running in production at the same time, and each one blocking everything it touches.

One of the biggest reasons I feel though, is lack of education. Even under strict deadlines it doesn't take any more time to write something correctly than it does to write it so it'll bring the system down. I give training sessions at work sometimes for the developers downstairs, and it's amazing to me how many of these top-notch .Net guys don't know the simplest things about SQL.

A quick example:
We have a table that holds just a single value at a time. It changes every week or so, but at any given time it only holds 1 value. 1 row, 1 column.
Here's the query brainchild chose to use.

Select Top 1 * from tblCurrentBatch b1 where ID in (select ID from tblCurrentBatch b2 where b1.ID = b2.ID)

I really can't stress this enough... there's ONE value and ONE column. the DDL is thus:

Create Table tblCurrentBatch
ID bigint

Dude, you may be under deadline, but you can't tell me that's the reason for this gross lack of knowledge.

Probably one of the better reasons is that they simply don't care. The above example is a clear example of this as well I think. A fair amount of developers I've talked to see a clear distinction between them and DBAs. It's their job to make the query run, and my job to make it run well. Even when I teach them how to write better code they quite often do it their way anyway. They just don't care. Then, they go out of their way to compile the query inside the code instead of making SPs so we can optimize it later. It's their way of fighting back. This way you have to come to them, explain the problem, and then get it fit into their busy schedule to be changed... and that's only if they agree. Their going to keep their code in production as long as possible, and they'll be damned if any DBA's going to tell them how to program.
I've written on this topic before, and I received a comment from someone that just doesn't make sense to me because I'm a DBA, but I think it sums up the developer's mind quite well.

This email is completely unedited and exactly as I received it:
You are a fucking idiot. Everything has its place - and having a dba tell me I can't use something I will respond with, YOU ARE FIRED - cause the database isn't the product. The business logic is what is sold, and performance is a factor, not the driver.

Frankly, this is just absurd. I'll tell you what's going to happen in this scenario. He's going to release his product and the customer will love it in the demo. Then he's going to put it into production with 100 users hitting it and it's going to crash and die. Then all his business logic will be out the window and he'll be running to us BEGGING AND PLEADING to fix his code.
The truth is we simply live in different worlds. We live in a sandbox where everybody has to get along, and they live in a closed world controlled by strict deadlines.

OK, so what kinds of things do we usually see from these crack developers? Well, I've seen the following...

Delete all records past a certain date.

Developer Solution:
Open a cursor against 75 million rows and compare each row to the given date and delete it if it passes.
Runtime: 18 hrs.

DBA Solution:
Delete from table where date < compareDate
Runtime: 30mins, depending on how much data was deleted.
*Make sure to use batch deletes... I'll write about that next week.


Select a specific batch number from a table.

Developer Solution:
Select * from BatchNumbers where BatchID like '%12345%'
Runtime: 45secs.

DBA Solution:
Select * from BatchNumbers where BatchID = '12345'
Runtime: < 1sec.
* I know, it's varchar... what can I do?

Get a list of customers with a sum of all their orders.

Developer Solution:
A complicated cursor solution that kept track of different variables and temp tables. Very limited in usefullness. I believe it was about 3 pages of code.
Runtime: 3hrs.

DBA Solution:
Select Customer, count(*) as 'Total Orders' from Orders group by Customer
Runtime: < 10secs.
*This went against a couple hundred million rows.

I'd love to hear about your similar experiences.

And remember... Friends don't let developers write SQL code.

DON'T Tolerate Fraud!!!

There has been some buzz lately that everyone should know about. There is an author out there who has written several articles on SQL Server and even a book. This author is a complete fraud. He is a plagiarist who has ripped off the hard work of many others and I could only hope that Microsoft sues his ass. Unfortunately it'll probably his publisher who will suffer.

As an author, I am outraged by this fraud who profits from others' work and research. I will do whatever I can to make sure that everyone knows that we won't tolerate this type of behavior. I work hard on all my articles and even the sarcasm in them. I borrow from BOL or other sources sometimes, but I always cite the source.

Steve Jones at wrote a blog on this topic as well, and he's already contacted MS and some publishers to let them know this has been going on.
Kevin Kline has also blogged on this.

The fraud's name is Rahul Sharma.
So nobody buy his book... ever, Ever, EVER!
His book is: Microsoft SQL Server™ 2000: A Guide to Enhancements and New Features

Check out "his" sample chapter here:

Compare that to the BOL replication stuff if you're bored.

Rahul my friend, you haven't heard the last of me. I'm not going to let this go. You've been faking your way through for a long time now, and I'm going to make it my personal mission to make sure everyone knows it.

Are There Advanced SQL Editors?

Recently I've been on a tear about the quality of SQL editors out there. They all claim to be loaded with features that make our jobs easier and save time. The problem is that none of them really deliver... Ok, lets be honest, most of them are crap.

The problem as I see it is that SQL editors are being written by C++ programers and not SQL programmers. Of course, you wouldn't want a SQL programmer writing an editor unless he could actually do it in SQL, but you do want him scoping it out. Sometimes it's like they don't even ask the SQL guys what's important to them. They just figure that since they're developers too, that that have the same needs. This really couldn't be further from the truth.

Most of the editor features don't actually save you any significant time. Sure, they make the letters pretty and connect to code vaults like VSS, but what else do you have for me? Anything that will actually save me time? No likely.

There are so many SQL editors out there and they all have pretty much the same features, but they all have the same major flaw. They all treat DBAs and SQL developers the same. DBAs have completely different needs from developers and if you truly want to save me some time, then build an editor that I can use too.

So how do SQL developers and DBAs differ? Well, for starters, developers write long, complex processes that can be complicated and very difficult to troubleshoot. And though they may write large chunks of code that is very similar, it's quite often not the same, so templates are useful to them. With templates they can just replace the important data and keep the rest of the query in tact. These templates tend to be rather small, and completely void of logic. So, they would create a template for creating a certain type of function, or a blank cursor, but neither of them would have the actual queries they needed. Developers also need debuggers, but really not as often as you would think. I have developed some pretty decent SPs myself, and the number of times I've pulled out the debugger in 10yrs, I can count on one hand. That's mainly because most errors are fairly recognizable and a debugger really only needs to be invoked for logic errors that are difficult to chase down.

DBAs don't work like that though. We mainly do production type work which tends to be more troubleshooting, conflict resolution, and query/index tuning. We also do some connectivity testing. The code we write tends to be a lot shorter, often times just a single line, or several lines of independent code. Some examples of our code would be DBCC SHOWCONTIG() or sp_who2, etc. As you can see, every bit of the logic we need is right there. So DBAs tend to run the exact same code on every system they work on, not just code that's similar to other code.

That's really just one example of the differences in the way DBAs and developers work. I'm going to be putting together a list of features, and shopping it around to the different companies so we can get the editor we want built.
What I'd like you guys to do is email me the features you want with a brief explanation of why it's necessary, and I'll put it on the list. My plan is to not just submit the list to a company, but to take it to them and insist this is what their community wants, and not give them the list until they promise to build it for us. We want reasonable timelines too... not just a promise.

Let's get this done so we can finally get a real editor that will actually save us some time.

The Database Religion

There are several religious debates in databases.
One of the biggest debates is on platform. If I hear one more DBA scream that Oracle is vastly superior to SQL I think I'm going to start ripping out my eyebrow hair from inside my eyelids.

The simple truth is that with the exception of some the older crap out there like Faircom and Pervasive, every DB has merit in different situations. Is Oracle better than SQL Server? It really depends on what you're doing. Oracle is better at some things, but it isn't the right choice a lot of times. MySQL is better for some things, and it could actually win in some competitions.

First I'd like to talk about why there are mixed shops to begin with. To be perfectly honest, I'm not against mixed shops. I used to be a database purist, but I'm more pragmatic than I used to be. Mixed shops tend to happen in 1 of 2 ways. Either you get a VP in who is loyal to a vendor and insists that everything from here on out be done in their DB of choice, or you get a few 3rd party apps that only use a certain vendor as a backend, so you're stuck with managing a new database if you want that product. Unfortunately, it's that vendor loyalty that I'm talking about when I talk about DBs being a religion. So few tend to care about using the best tool for the job, they're usually more concerned with what makes them feel more macho for some reason.

Come on now... there's no reason to pick Oracle if all you're doing is putting together a simple website. And while Yukon is going to close the gap, Oracle has better HA features than SQL2K, so it would be a better choice if you needed some real 24/7 support. The same goes for XML. You wouldn't choose SQL2K over Oracle if you needed rich XML support. You also wouldn't choose MySQL if you needed rich stored procedure or transaction support, or really intense 24/7. You would choose MySQL however, if you were putting together a fairly simple app or website and just needed very quick response times to fairly large data sets. Some people swear by MySQL, I just don't happen to be one of them.

So mixed shops are ok, you just have to start putting more reasoning behind it. Go beyond that ridiculous loyalty you feel towards your favorite vendor because as we've found out with Quest, a vendor can turn on you without warning and the next thing you know you've got your entire shop full of their product and it's no longer doing the job for you.

It's really all just marketing anyway. In my experience most DBAs don't know enough about DBs to make a decision to begin with. Most SQL DBAs I talk to know so incredibly little about SQL, much less Oracle or MySQL or DB2. Their decisions are made purely off of marketing or basic familiarity. I can't count the number of times I've called Oracle support to have some brain-dead tech on the line make some stupid comment about SQL Server when they clearly don't have any idea what they're talking about. It's pathetic really.

The truth is that there are good reasons to go with pretty much any vendor, and you just have to find the right one. Those reasons aren't always technical either. Put simply, licensing can quite often be the deciding factor. And TCO is much more than licensing... it's extensibility, features, east of management, robustness, etc. Holding a lesser cost of not having to keep 5 different types of DBAs in-house is also included in TCO. These are all factors, so let's be blunt... you're not going to choose Oracle enterprise for your intranet when MySQL will do. Just the same you're not going to choose MySQL when you need to load a 4TB warehouse with millions of calculations. You're probably going to choose an Oracle and RAC solution. And for all the ground in between there are plenty of choices.

See, I know some people who are open source disciples and never waver from their freeware god, but when you get right down to it, none of the open source DBs have the same feature set the big 4 vendors have. They don't have any BI, and most of the time no real DTS capability, and monitoring is extremely limited. Not many vendors have monitoring solutions coded for MySQL so getting alerts based off of downtime and performance is more involved using an open source solution than a full-blown product. That's a simple fact of life. You often times get what you pay for, and this is one of those times that it's abundantly true.

TPC is Useless

If you look at everyone's latest TPCs you'll notice that they all reach incredible numbers of transactions/hr. The one thing they don't mention is that they not only reach these numbers with hardware configurations that almost nobody will ever get to work with, but with very few exceptions NOBODY has the transaction requirements that these products reach. That means that only the smallest percentage of companies worldwide will ever really tax any of the Big 4 with transactions. That also means that there is a lot of middle ground where any of them could easily play without any problem whatsoever. Yukon is going to make some major waves and Oracle's really going to feel it.

Over the years SQL Server DBAs have had to come to grips with the fact that Oracle actually is better at the higher end processing. Now, Oracle DBAs are having to come to grips with the fact that SQL Server is more cost effective. SQL Server is also really closing the gap in performance, which is another thing that Oracle DBAs are having to get used to.

So seriously... all you guys who turn this stuff into some kind of religious war just get off your high horse. Make intelligent decisions based off of the facts, not just your outdated opinions of what vendor is politically best.
