Read more about minimum server memory and maximum server memory in this article Server Memory Server Configuration Options.

Formula for dynamically allocating maximum memory

The formula is based on the SQL Max Memory Calculator website. The website code is in the sql-max GitHub repository maintained by @mirontoli. The dynamic maximum memory (in MB) is calculate with this formula: SQL Max Memory = TotalPhysicalMemory - (NumOfSQLThreads*ThreadStackSize) - (1024*CEILING(NumOfCores/4)) - OSReservedMemory.

NumOfSQLThreads
  • If the number of cores is less than or equal to 4, the number of SQL threads is set to: 256 + (NumberOfCores - 4) * 8.
  • If the number of cores is greater than 4, the number of SQL threads is set to: 0 (zero).
ThreadStackSize
  • If the architecture of windows server is x86, the size of thread stack is 1MB.
  • If the architecture of windows server is x64, the size of thread stack is 2MB.
  • If the architecture of windows server is IA64, the size of thread stack is 4MB.
OSReservedMemory
  • If the total physical memory is less than or equal to 20GB, the percentage of reserved memory for OS is 20% of total physical memory.
  • If the total physical memory is greater than 20GB, the percentage of reserved memory for OS is 12.5% of total physical memory.

xSQLServerScript

Provides the means to run a user generated T-SQL script on the SQL Server instance. Three scripts are required; Get T-SQL script, Set T-SQL script and the Test T-SQL script.

Scripts

Get T-SQL Script (GetFilePath)

The Get T-SQL script is used to query the status when running the cmdlet Get-DscConfiguration, and the result can be found in the property GetResult.

Test T-SQL Script (TestFilePath)

The Test T-SQL script is used to test if the desired state is met. If Test T-SQL raises an error or returns any value other than 'null' the test fails, thus the Set T-SQL script is run.

Set T-SQL Script (SetFilePath)

The Set T-SQL script performs the actual change when Test T-SQL script fails.

Requirements

  • Target machine must be running Windows Server 2008 R2 or later.
  • Target machine must be running SQL Server 2008 or later.
  • Target machine must have access to the SQLPS PowerShell module or the SqlServer PowerShell module.

Note: There is a known problem running this resource using PowerShell 4.0. See issue #273 for more information.

Parameters

  • [String] ServerInstance (Key): The name of an instance of the Database Engine. For a default instance, only specify the computer name. For a named instances, use the format ComputerName\InstanceName.
  • [String] SetFilePath (Key): Path to the T-SQL file that will perform Set action.
  • [String] GetFilePath (Key): Path to the T-SQL file that will perform Get action. Any values returned by the T-SQL queries will also be returned by the cmdlet Get-DscConfiguration through the GetResult property.
  • [String] TestFilePath (Key): Path to the T-SQL file that will perform Test action. Any script that does not throw an error or returns null is evaluated to true. The cmdlet Invoke-Sqlcmd treats T-SQL Print statements as verbose text, and will not cause the test to return false.
  • [PSCredential] Credential (Write): The credentials to authenticate with, using SQL Authentication. To authenticate using Windows Authentication, assign the credentials to the built-in parameter PsDscRunAsCredential. If both parameters Credential and PsDscRunAsCredential are not assigned, then SYSTEM account will be used to authenticate using Windows Authentication.
  • [UInt32] QueryTimeout (Write): Specifies, as an integer, the number of seconds after which the T-SQL script execution will time out. In some SQL Server versions there is a bug in Invoke-Sqlcmd where the normal default value 0 (no timeout) is not respected and the default value is incorrectly set to 30 seconds.
  • [String[]] Variable (Write): Specifies, as a string array, a scripting variable for use in the sql script, and sets a value for the variable. Use a Windows PowerShell array to specify multiple variables and their values. For more information how to use this, please go to the help documentation for Invoke-Sqlcmd.

Read-Only Properties from Get-TargetResource

  • [String] GetResult (Read): Contains the values returned from the T-SQL script provided in the parameter GetFilePath when cmdlet Get-DscConfiguration is run.

Credentials

PsDscRunAsCredential

If PsDscRunAsCredential is set, the installation will be performed with those credentials, and the user name will be used as the first system administrator.

SYSTEM

If PsDscRunAsCredential is not assigned credentials then installation will be performed by the SYSTEM account. When installing as the SYSTEM account, then parameter SQLSysAdminAccounts and ASSysAdminAccounts must be specified when installing feature Database Engine and Analysis Services respectively.

Parameters

  • [String] Action (Write): The action to be performed. Defaults to 'Install'. Note: AddNode is not currently functional. { Install | InstallFailoverCluster | AddNode | PrepareFailoverCluster | CompleteFailoverCluster }

Using this parameter will trigger a copy of the installation media to a temp folder on the target node. Setup will then be started from the temp folder on the target node. For any subsequent calls to the resource, the parameter SourceCredential is used to evaluate what major version the file 'setup.exe' has in the path set, again, by the parameter SourcePath. To know how the temp folder is evaluated please read the online documentation for System.IO.Path.GetTempPath(). If the path, that is assigned to parameter SourcePath, contains a leaf folder, for example '\server\share\folder', then that leaf folder will be used as the name of the temporary folder. If the path, that is assigned to parameter SourcePath, does not have a leaf folder, for example '\server\share', then a unique GUID will be used as the name of the temporary folder.
