In one of our recent CSS cases, we noticed a strange difference between the Windows Small Business Server (SBS) 2008 x64 and Windows Server 2008 x64. One could create a Data Collector Set (DCS) with SQL Server x86 counters, collect and view the samples just fine on the SBS 2008 x64, out of the box. However, on Windows Server 2008 x64 this proved to be not possible.
This workaround will be provided “as-is”, with no support whatsoever or liability from Microsoft. For use in a productive environment, we recommend you to install the x64 version of SQL Server especially when running on a x64 OS.
First let’s take a look at the two scenarios:
Windows SBS 2008 x64 with SQL Server 2005 SP2 x86 installed by default
– The SQL Performance counters are stored in a DLL called sqlctr90.dll.
Here you see that on a SBS 2008 server, there are two DLLs installed by default: one 32bit in c:\windows\syswow64 and 64bit in c:\windows\system32
Windows Server 2008 SP2 x64 with SQL Server 2005 SP3 x86
– If we search now for the sqlctr90.dll, we only see one file: the 32bit version in c:\windows\syswow64
The workaround is to simply copy the 64bit version of “sqlctr90.dll” from another machine running a x64 SQL instance, to the “c:\windows\system32” directory of the Server 2008 x64 OS machine running SQL Server 2005 x86. We recommend using the DLL from similar SP levels of SQL Server (SP3 since SP2 is actually not supported any more!)
Once you copy the DLL, you can proceed with creating a custom DCS with SQL Server 32bit counters:
1. Choose a name for the DCS and select “create manually (advanced)”
2. Choose “Performance counter” and click “Next”
3. Choose any SQL related counters (here you see General Statistics for example):
4. Here you select the location, wrap up the DCS creation and start the collection.
After a chosen amount of time, you can stop the collection.
5. To view the counters, in Perfmon you select and open the created BLG file of the custom DCS
6. You now select which objects you would like to see displayed:
7. As you can see, sample collection works fine.
