Performance Counters Missing

We’ve been running SQL Server 2000 x86 on Windows Server 2003 R2 x64 for some time. While there have been a few issues here and there, monitoring SQL related counters can be troublesome whether you are local or remote.

If you are local to the server when you open up performance monitor you will receive the x64 counters and this won’t help you since your SQL Server is x86. For the 32 bit version just use %SystemRoot%\SysWow64\Perfmon.exe.

If you are remote then you’ll need to make some registry modifications on the server that you are monitoring. You’ll need to modify 2 registry entries to read SysWow64 instead of System32:

“ImagePath”=”%SystemRoot%\SysWow64\svchost.exe -k regsvc”

Restart the Remote Registry Service and you should be good to go now.

(Maybe you couldn’t run SQL 2000 under a x64 bit OS at the time of this writing)

SQL University

Jorge Segarra is onto something pretty cool. Head on over to SQL University and check it out. I’m going to run through it myself in the coming weeks because everyone should be trying to polish up on the SQL.

Setting up your server

While the Microsoft reference may say that you should keep the operating system the same, it seems hard to believe that there aren’t situations where one would decide to bypass this recommendation. If you are sitting on Windows 2003 x86 with SQL Server 2000 x86 and you have the option to go to Windows 2008 x64 with SQL Server 2005 x64 then it might be a good time to move on that. Microsoft Windows 2008 R2 is the first OS to only be offered in a 64-bit version. If you want to be set for a few years, now might be time to go ahead and bite the x64 bullet. But you should also be aware of the downsides that can be associated with this decision. If you have 100 DTS Packages that primarily use Excel connections then you may eventually regret the decision to go with x64. It would also be a good idea to make a decision about going to Windows Server 2008.

RAID Levels can also be something to consider during this time. Kendal Van Dyke has an excellent series on Disk Performance that can be useful when looking at RAID levels. While you will often read that RAID 10 gives you the best bang, you may not have any buck left. Generally, it’s recommended that you stick with RAID 5 for your data files and RAID 1 for your log files. If you are not connected to a SAN and your drives are local then now is the time to get the RAID levels right.

Once you have your OS installed, its time to get it configured so that it works optimally for SQL Server. There are several key fundamentals about SQL Server installations that you will need to understand as you move forward and there are great resources from Brent Ozar and Chad Boyd included in the resource links below. Another item that Brent touches on briefly is that of Disk Partition Alignment. Jimmy May has some excellent information on that, and the SQL CAT team recently published a new whitepaper that is helpful.

Upgrading your Plan

After reading through the SQL Server 2005 Upgrade Technical Reference Guide, you should have a good idea about which direction you want to move forward. The upgrade path and upgrade method will help you modify your plan so that you have the best chance to succeed. Depending on your environment, your choices may already be made for you. Regardless of whether or not you are doing an In-Place or a Side-by-Side upgrade, it will be very beneficial for you to do some testing before you flip any kind of switch to go live with SQL 2005.

In the best of scenarios, you can find another server that you can use to do testing and simulate what the environment will look like.  If you cannot find another server that can be used solely for this purpose, maybe you could look at using virtualization to meet this need.  You probably will not be able to simulate the hardware completely, but it should be better than nothing. Setting up a virtual instance is beyond the scope of this article but it should be fairly easy to set that up with resources found online. VMware and Microsoft both have virtualization software that can be used for free.

Scalability Experts has a tool called SQL Server Upgrade Assistant 2005 that can be used to verify how your applications will run against SQL Server 2005 instead of 2000. Even if you do not use this tool, by reading through the User Guide you can develop your own plan for testing and that should help you discover the items you need to address.

In the fourth part of this series, I’ll describe some things you should consider as you are setting up your new server.
