function Restart-DbaSqlService { <# .SYNOPSIS Restarts SQL Server services on a computer. .DESCRIPTION Restarts the SQL Server related services on one or more computers. Will follow SQL Server service dependencies. Requires Local Admin rights on destination computer(s). .PARAMETER ComputerName The SQL Server (or server in general) that you're connecting to. This command handles named instances. .PARAMETER InstanceName Only affects services that belong to the specific instances. .PARAMETER Credential Credential object used to connect to the computer as a different user. .PARAMETER Type Use -Type to collect only services of the desired SqlServiceType. Can be one of the following: "Agent","Browser","Engine","FullText","SSAS","SSIS","SSRS" .PARAMETER Timeout How long to wait for the start/stop request completion before moving on. Specify 0 to wait indefinitely. .PARAMETER ServiceCollection A collection of services from Get-DbaSqlService .PARAMETER 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. .PARAMETER WhatIf Shows what would happen if the cmdlet runs. The cmdlet is not run. .PARAMETER Confirm Prompts you for confirmation before running the cmdlet. .PARAMETER Force Will stop dependent SQL Server agents when stopping Engine services. .NOTES Author: Kirill Kravtsov( @nvarscar ) dbatools PowerShell module (https://dbatools.io) Copyright (C) 2017 Chrissy LeMaire License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Restart-DbaSqlService .EXAMPLE Restart-DbaSqlService -ComputerName sqlserver2014a Restarts the SQL Server related services on computer sqlserver2014a. .EXAMPLE 'sql1','sql2','sql3'| Get-DbaSqlService | Restart-DbaSqlService Gets the SQL Server related services on computers sql1, sql2 and sql3 and restarts them. .EXAMPLE Restart-DbaSqlService -ComputerName sql1,sql2 -Instance MSSQLSERVER Restarts the SQL Server services related to the default instance MSSQLSERVER on computers sql1 and sql2. .EXAMPLE Restart-DbaSqlService -ComputerName $MyServers -Type SSRS Restarts the SQL Server related services of type "SSRS" (Reporting Services) on computers in the variable MyServers. .EXAMPLE Restart-DbaSqlService -ComputerName sql1 -Type Engine -Force Restarts SQL Server database engine services on sql1 forcing dependent SQL Server Agent services to restart as well. #> [CmdletBinding(DefaultParameterSetName = "Server", SupportsShouldProcess = $true)] Param ( [Parameter(ParameterSetName = "Server", Position = 1)] [Alias("cn", "host", "Server")] [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [Alias("Instance")] [string[]]$InstanceName, [ValidateSet("Agent", "Browser", "Engine", "FullText", "SSAS", "SSIS", "SSRS")] [string[]]$Type, [parameter(ValueFromPipeline = $true, Mandatory = $true, ParameterSetName = "Service")] [object[]]$ServiceCollection, [int]$Timeout = 30, [PSCredential]$Credential, [switch]$Force, [switch][Alias('Silent')]$EnableException ) begin { $processArray = @() if ($PsCmdlet.ParameterSetName -eq "Server") { $serviceParams = @{ ComputerName = $ComputerName } if ($InstanceName) { $serviceParams.InstanceName = $InstanceName } if ($Type) { $serviceParams.Type = $Type } if ($Credential) { $serviceParams.Credential = $Credential } if ($EnableException) { $serviceParams.Silent = $EnableException } $serviceCollection = Get-DbaSqlService @serviceParams } } process { #Get all the objects from the pipeline before proceeding $processArray += $serviceCollection } end { $processArray = [array]($processArray | Where-Object { (!$InstanceName -or $_.InstanceName -in $InstanceName) -and (!$Type -or $_.ServiceType -in $Type) }) foreach ($service in $processArray) { if ($Force -and $service.ServiceType -eq 'Engine' -and !($processArray | Where-Object { $_.ServiceType -eq 'Agent' -and $_.InstanceName -eq $service.InstanceName -and $_.ComputerName -eq $service.ComputerName })) { Write-Message -Level Verbose -Message "Adding Agent service to the list for service $($service.ServiceName) on $($service.ComputerName), since -Force has been specified" #Construct parameters to call Get-DbaSqlService $serviceParams = @{ ComputerName = $service.ComputerName InstanceName = $service.InstanceName Type = 'Agent' } if ($Credential) { $serviceParams.Credential = $Credential } if ($EnableException) { $serviceParams.Silent = $EnableException } $processArray += @(Get-DbaSqlService @serviceParams) } } if ($processArray) { $services = Update-ServiceStatus -ServiceCollection $processArray -Action 'stop' -Timeout $Timeout -EnableException $EnableException foreach ($service in ($services | Where-Object { $_.Status -eq 'Failed'})) { $service } $services = $services | Where-Object { $_.Status -eq 'Successful'} if ($services) { Update-ServiceStatus -ServiceCollection $services -Action 'restart' -Timeout $Timeout -EnableException $EnableException } } else { Stop-Function -EnableException $EnableException -Message "No SQL Server services found with current parameters." } } } |
