function Test-DbaLinkedServerConnection { <# .SYNOPSIS Test all linked servers from the sql servers passed .DESCRIPTION Test each linked server on the instance .PARAMETER SqlInstance The SQL Server that you're connecting to. .PARAMETER SqlCredential Credential object used to connect to the SQL Server as a different user .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. .NOTES Tags: LinkedServer Author: Thomas LaRock ( https://thomaslarock.com ) dbatools PowerShell module (https://dbatools.io) Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Test-DbaLinkedServerConnection .EXAMPLE Test-DbaLinkedServerConnection -SqlInstance DEV01 Test all Linked Servers for the SQL Server instance DEV01 .EXAMPLE Test-DbaLinkedServerConnection -SqlInstance sql2016 | Out-File C:\temp\results.txt Test all Linked Servers for the SQL Server instance sql2016 and output results to file .EXAMPLE Test-DbaLinkedServerConnection -SqlInstance sql2016, sql2014, sql2012 Test all Linked Servers for the SQL Server instances sql2016, sql2014 and sql2012 .EXAMPLE $servers = "sql2016","sql2014","sql2012" $servers | Test-DbaLinkedServerConnection -SqlCredential (Get-Credential sqladmin) Test all Linked Servers for the SQL Server instances sql2016, sql2014 and sql2012 using SQL login credentials .EXAMPLE $servers | Get-DbaLinkedServer | Test-DbaLinkedServerConnection Test all Linked Servers for the SQL Server instances sql2016, sql2014 and sql2012 #> [CmdletBinding()] param ( [Parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstance[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { if ($instance.LinkedLive) { $linkedServerCollection = $instance.LinkedServer } else { try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } } $linkedServerCollection = $server.LinkedServers foreach ($ls in $linkedServerCollection) { Write-Message -Level Verbose -Message "Testing linked server $($ls.name) on server $($ls.parent.name)" try { $null = $ls.TestConnection() $result = "Success" $connectivity = $true } catch { $result = $_.Exception.InnerException.InnerException.Message $connectivity = $false } New-Object Sqlcollaborative.Dbatools.Validation.LinkedServerResult($ls.parent.ComputerName, $ls.parent.ServiceName, $ls.parent.DomainInstanceName, $ls.Name, $ls.DataSource, $connectivity, $result) } } } } |
