Msg 5845
useless software package - the software has been struggling for quite some time now and the only way I can lock pages in memory sql server 2012 get the software to work is to continiually change the maximum server memory on SQL. I understand that this is bad practice but its kept the server going for several months now..... until yesterday! Financial constraints mean this is the only solution for me at the moment :( I'm now receiving this error message when trying to change the memory levels and the allocated memory is not moving ---Alter Failed. (Microsoft.SqlServer.Smo) Additional Information: ---An exception occured while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo) -----Address Windows Extensions (AWE) requires the 'lock pages in memory' privilege which is not currently present in the access token of the process. (Microsoft SQL Server, Error: 5845) Can anyone offer me any helpful advice - hopefully not run away!

If you don't want to use AWE then you can disable it by below query sp_configure 'awe enabled', 0 If you want to fix error, then SQL Service account should have "'lock pages in memory" privilege. Go to Start > Run > Secpol.msc Security setting > Local Policies> User Rights Assignment Locate "Lock pages in memory" policy and add SQL Service account (startup account) over there.

| twitter) and he’s asking for SQL Server myths and misconceptions to be de-bunked. I’ve got 2 myths I’d like to set the record straight about. They’re rather closely related, and concern the "Lock Pages in Memory" setting. What’s it do? Without getting into an entire lesson on how operating systems manage memory, I’ll try to shrink this down into about a 15 second blurb for benefit of those who might not already know. Every computer has a finite amount of memory (RAM). Regardless of how much memory you have, all of the processes running on your computer combined will probably allocate more memory than is physically available. Since not every process needs all it’s memory at any given second, operating https://social.msdn.microsoft.com/Forums/sqlserver/en-US/bf9ffa88-13b4-411d-bac7-58def27b869b/awe-error-in-sql-server-2005?forum=sqldatabaseengine systems employ a memory management scheme knowing as "paging", which means that inactive data stored in RAM will be written to disk in a file called the "page file". This typically happens unbeknownst to the application whose data has just been paged. When the application needs this data again, it is read back from the page file into memory and the process continues. The downside of all this, of course, is that reading and writing to/from disk http://www.bobpusateri.com/archive/2010/10/two-myths-about-lock-pages-in-memory/ takes time, and is slower than if the data had just stayed in memory to begin with. "Lock Pages in Memory" (LPM) allows some processes to skirt around this by declaring their allocated portions of memory as "locked", therefore preventing the operating system from paging it to disk. This can result in significant performance gains for high-demand applications such as SQL Server. To grant a process the rights to utilize LPM, check out Microsoft’s instructions. The Myths Now that I’m done with the setup, let’s get to the myths. Myth the first is that LPM is only available in SQL Server Enterprise Edition. This once was true, but is no longer the case. Around April of 2009 it was announced that users of SQL 2005 and 2008 Standard Edition are also able to join the party and utilize LPM. To take advantage of this, systems must be upgraded to at least: SQL Server 2005 Cumulative Update 4 for Service Pack 3 or SQL Server 2008 Cumulative Update 2 for Service Pack 1 So now let’s say you’re running Standard Edition of a version listed above (or later) and you have the Lock Pages In Memory security setting enabled for the SQL Server Service account, just like you’d do for Enterprise Edition. You’re now good to go, right? Not exactly, but it’s commonly thought that it should work at this poi
5845, Level 16, State 1, Line 1 Address Windowing Extensions (AWE) requires the ‘lock pages in memory' privilege which is not currently present in the access https://sqlfindings.wordpress.com/2009/10/10/lock-pages-in-memory-privilege-which-is-not-currently-present-in-the-access-token-of-the-process/ token of the process. we generally face ‘Lock pages in memory' privilege error while either enabling AWE from SQL Server properties or using Reconfigure with Override command while changing sql server configuration settings in 32-bit machine. Solution: The windows policy Lock Pages in Memory option is disabled by default.This privilege must be enabled to configure AWE(Address Windowing Extensions). Locking pages in memory sql server is not required on 64-bit operating systems.This policy determins which accounts can use a process to keep data in physical memory, preventing the system from paging the data to virtual memory on disk. you can use following steps to windows group policy tool to enable the account used by SQL Server. 1. Start -> Run -> gpedit.msc 2. Group Policy console -> Computer error 5845 sql Configuration -> windows Settings ->Security Settings -> Local Policies ->User Rights Assignment 3. In the right pane, search for Lock pages in memory. Double click on it and in the dialog box you will add an SQL Server Service account. Once above steps complete, you will restart SQL Services and try to reconfigure the sql server configuration. You will not face lock page in memory error. Like this:Like Loading...
