Windows-based applications can use Windows AWE Address Windowing Extensions APIs to allocate and to map physical memory into the process address space. Memory that is allocated by using this method is never paged out by the operating system and is locked down until the application explicitly frees it or exits.

The application requires the “Lock Pages In Memory” user right LPIM to be granted for the application to be able to lock pages in memory.

The SQL Server bit version uses “locked pages” to prevent the process working set committed memory from being paged out or trimmed by the operating system.

The use of AWE APIs for memory management in bit SQL Server is also frequently referred as “locked pages. The behavior is different, depending on the edition of SQL Server in these versions.

SQL Server bit versions , , and R2 use “locked pages” when the “awe enabled” SQL Server feature is enabled. Starting with SQL Server , the memory manager simplifies the usage of “locked pages” across supported editions and processor architectures.

In SQL Server , you can enable “locked pages” by granting the “lock pages in memory” user right for the startup account for the instance of SQL Server in Windows. This is applicable for Standard, Business Intelligence, and Enterprise editions of SQL Server running on both bit and bit processor architectures.

The following table provides the requirements to enable “locked pages” in different versions and editions of SQL Server on different platforms:. The LPIM user right refers to the “Lock Pages in Memory” Windows user right.

This user right should be assigned to the SQL Server service startup account. You do not have to use Trace Flag in SQL Server You can remove this trace flag from the startup parameters after you upgrade your instance to SQL Even though the “awe enabled” feature is not available in bit SQL Server , you can still use the “locked pages” feature by assigning the “lock pages in memory” user right for the SQL Server startup account.

When you enable “locked pages,” it is very important to set an appropriate value for “max server memory” and for “min server memory” configuration options for each instance of SQL Server to avoid system-wide problems. Use the following methods to determine whether the SQL Server instance is using “locked pages”:.

select osn. The following table provides more information about the products or tools that automatically check for this condition on your instance of SQL Server and on the versions of the SQL Server product against which the rule is evaluated. You did not enable the trace flag , as a result the SQL Server instance did not use locked page allocations. Note A bug condition could prevent these rules from providing the appropriate warnings.

You grant the “Lock Pages in Memory” user right to the SQL Server service startup account. Now you attempt to upgrade this SQL Server instance to SQL Server Now the upgraded SQL Server instance starts using locked page allocations. This upgrade rule warns you about this change in behavior. Consider the following scenario on an X86 system: You install SQL Server [ R2, , ] standard edition.
