DOCUMENT:Q269832 11-JUN-2002 [sms] TITLE :SMS: Case Sensitivity Slows Down Queries PRODUCT :Microsoft Systems Management Server PROD/VER::2.0,2.0 SP1,2.0 SP2 OPER/SYS: KEYWORDS:kbenv kbtool kbsms200 kbsms200bug ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Systems Management Server versions 2.0, 2.0 SP1, 2.0 SP2 ------------------------------------------------------------------------------- IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: Q256986 Description of the Microsoft Windows Registry SYMPTOMS ======== Because the Web-Based Enterprise Management (WBEM) Query Language is not case sensitive, it causes an unnecessarily large amount of processing overhead on SQL servers that are not case sensitive because all string comparisons are wrapped by a case conversion call. CAUSE ===== This problem can occur if the Systems Management Server (SMS) provider does not check the case sensitivity of the SQL server. Although it does not check the case sensitivity of the SQL server, it still provides case conversion, and this can cause the excessive overhead. RESOLUTION ========== A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem. This fix may receive additional testing at a later time, to further ensure product quality.

STATUS ====== Microsoft has confirmed this to be a problem in Systems Management Server version 2.0. MORE INFORMATION ================ WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. Apply this fix to all of the primary sites in the SMS hierarchy. It is necessary to apply the hotfix only to the site servers; you do not need to apply the fix to computers that are running the SMS Administrator console. To install the fix, use one of the following methods. How to Use the Hotfix Installer ------------------------------- NOTE: You can use this method only on Intel-based computers. 1. Copy the hotfix folder structure to a share on your network. Q269832.exe is a Microsoft Windows Installer file that updates specific files on your site server. 2. Log on to your site server by using an account with administrative privileges. 3. On the site server, quit the SMS Administrator console. 4. Run Q269832.exe, and then follow the directions in the wizard. You can run the file in Quiet mode by using the "/s" (without the quotation marks) switch. How to Manually Install the Hotfix ---------------------------------- To determine if the SMS provider is located on the site server or on a remote computer that is running Microsoft SQL Server, view the following registry key on the primary site server: HKEY_LOCAL_MACHINE\Software\Microsoft\SMS\Setup Value: Provider Location NOTE: If the computer that is identified in this registry key is not the local site server, use the installation steps for a remote provider. Site System with Local Provider: 1. Quit the SMS Administrator console, and then stop all SMS services including the Windows Management service and the SMS_SQL_MONITOR service. 2. Use Regsvr32.exe to unregister the existing SMS provider file, type "regsvr32 /u \bin\\smsprov.dll" (without the quotation marks) at a command prompt, and then press ENTER. 3. Replace the Smsprov.dll file in the \bin\ folder with the version that you obtained from the hotfix. 4. Use Regsvr32.exe to register the updated SMS provider file, type "regsvr32 \bin\\smsprov.dll" (without the quotation marks) at a command prompt, and then press ENTER. 5. Restart all SMS services. Site System with Remote Provider: 1. Quit the SMS Administrator console, and then stop all SMS services. 2. Use Regsvr32.exe to unregister the existing SMS Provider file, type "regsvr32 /u \bin\\smsprov.dll" (without the quotation marks) at a command prompt, and then press ENTER. 3. Replace the Smsprov.dll file in the \bin\ folder with the version that you obtained from the hotfix. 4. Use Regsvr32.exe to register the updated SMS provider file, type "regsvr32 \bin\\smsprov.dll" (without the quotation marks) at a command prompt, and then press ENTER. 5. Restart all SMS services.
