He holds a Masters of Science diploma and numerous database certifications. I additionally executed the below T-SQL script and it now exhibits the sql_memory_model value as 2 which is "LOCK_PAGES". Below we will see the T-SQL script now exhibits a reminiscence worth for locked page allocation. Once you'll click OK, the account will show in Local Security Setting tab as shown below. You can see there are various options given on the left side pane in the above display screen.
Double click the Lock pages in memory policy to open its properties window. Click the first tab Local Security Settingand then click on Add User or Groupto add the SQL Server service account. The first method to check this setting is by executing the beneath T-SQL statement. If output of "locked_page_allocations_kb" shows 0 it means this setting is disabled and never being used for SQL Server.
