NAME Set-DbaMaxDop
SYNOPSIS
Sets SQL Server maximum degree of parallelism (Max DOP), then displays information relating to SQL Server Max DOP
configuration settings. Works on SQL Server 2005 and higher.
SYNTAX
Set-DbaMaxDop [[-SqlInstance] <Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>] [[-SqlCredential]
<Pscredential>] [[-Database] <System.Object[]>] [[-ExcludeDatabase] <System.Object[]>] [[-MaxDop] <Int>]
[[-InputObject] <Psobject>] [-AllDatabases <Switch>] [-EnableException <Switch>] [<CommonParameters>]
DESCRIPTION
Uses the Test-DbaMaxDop command to get the recommended value if -MaxDop parameter is not specified.
These are just general recommendations for SQL Server and are a good starting point for setting the "max degree of
parallelism" option.
You can set MaxDop database scoped configurations if the server is version 2016 or higher
PARAMETERS
-AllDatabases [<Switch>]
If this switch is enabled, Max DOP will be set on all databases. This switch is only useful on SQL Server 2016
and higher.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-Database [<System.Object[]>]
Specifies one or more databases to process. Options for this list are auto-populated from the server. If
unspecified, all databases will be processed.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-EnableException [<Switch>]
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.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-ExcludeDatabase [<System.Object[]>]
Specifies one or more databases to exclude from processing. Options for this list are auto-populated from the
server
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-InputObject [<Psobject>]
If Test-SqlMaxDop has been executed prior to this function, the results may be passed in via this parameter.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-MaxDop [<Int>]
Specifies the Max DOP value to set.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlCredential [<Pscredential>]
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.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
-SqlInstance [<Sqlcollaborative.Dbatools.Parameter.DbaInstanceParameter[]>]
The target SQL Server instance or instances. Defaults to localhost.
Required? false
Position? named
Default value
Accept pipeline input? False
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
