SQL Server Lock Pages in Memory

How to enable "Lock pages in Memory" at the Windows level?

1. On the Start menu, click Run. In the Open box, type gpedit.msc. The Group Policy dialog box opens.
2. On the Group Policy console, expand Computer Configuration, and then expand Windows Settings.
3. Expand Security Settings, and then expand Local Policies.
4. Select the User Rights Assignment folder. The policies will be displayed in the details pane.
5. In the pane, double-click Lock pages in memory.
6. In the Local Security Policy Setting dialog box, click Add.
7. In the Select Users or Groups dialog box, add the account that runs the SQL Server Service.

8. Restart the machine for these changes to take effect.

If you are running an Enterprise or Developer Edition of SQL Server 2005 or 2008, please stop here. The rest of the steps are for the Standard Edition Only.

Ensure that the build of SQL Server 2008 is Cumulative Update 2 on Service Pack 1. Preferably, run the "select @@version" command against the SQL Server Instance and verify that the build is 10.00.2714.00. In case of SQL Server 2005, please verify that the build is 9.00.4226.
9. Now set the Trace Flag 845 as a startup trace flag. This can be done by adding
-T845 to the startup parameters from the SQL Server Configuration Manager. Please refer to the screenshot below:

SQLConfigManager
10. Restart the SQL Server Service.
11. Verify that the following message is written in the SQL Server ErrorLog file at startup:
Using locked pages for buffer pool


Note: Enabling Locked Pages may have a negative performance impact on your system performance. Please consider all potential effects before you use this option. Enabling this trace flag on the Enterprise Edition or the Developer Edition has no effect.
