More info: https://msdn.microsoft.com/en-us/library/cc645587.aspx http://www.sqlservercentral.com/blogs/glennberry/2011/02/25/some-suggested-sql-server-2008-r2-instance-configuration-settings/

These are just general recommendations for SQL Server and are a good starting point for setting the "optimize for ad-hoc workloads" option.

Syntax

Test-DbaOptimizeForAdHoc
    [-SqlInstance] <DbaInstanceParameter[]>
    [[-SqlCredential] <PSCredential>]
    [-EnableException]
    [<CommonParameters>]

 

Examples

 

Example: 1
PS C:\> Test-DbaOptimizeForAdHoc -SqlInstance sql2008, sqlserver2012

Validates whether Optimize for AdHoc Workloads setting is enabled for servers sql2008 and sqlserver2012.

Required Parameters

-SqlInstance

A collection of one or more SQL Server instance names to query.

Alias
Required True
Pipeline true (ByValue)
Default Value

Optional Parameters

-SqlCredential

Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance.

Alias
Required False
Pipeline false
Default Value
-EnableException

By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

Alias
Required False
Pipeline false
Default Value False
