function Disable-DbaTraceFlag { <# .SYNOPSIS Disable a Global Trace Flag that is currently running .DESCRIPTION The function will disable a Trace Flag that is currently running globally on the SQL Server instance(s) listed .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER TraceFlag Trace flag number to enable globally .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: TraceFlag, DBCC Author: Garry Bargsley (@gbargsley), http://blog.garrybargsley.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Disable-DbaTraceFlag .EXAMPLE PS C:\> Disable-DbaTraceFlag -SqlInstance sql2016 -TraceFlag 3226 Disable the globally running trace flag 3226 on SQL Server instance sql2016 #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer", "SqlServers")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [parameter(Mandatory)] [int[]]$TraceFlag, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Error occurred while establishing connection to $instance" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $current = Get-DbaTraceFlag -SqlInstance $server -EnableException foreach ($tf in $TraceFlag) { $TraceFlagInfo = [pscustomobject]@{ SourceServer = $server.ComputerName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName TraceFlag = $tf Status = $null Notes = $null DateTime = [DbaDateTime](Get-Date) } if ($tf -notin $current.TraceFlag) { $TraceFlagInfo.Status = 'Skipped' $TraceFlagInfo.Notes = "Trace Flag is not running." $TraceFlagInfo Write-Message -Level Warning -Message "Trace Flag $tf is not currently running on $instance" continue } try { $query = "DBCC TRACEOFF ($tf, -1)" $server.Query($query) } catch { $TraceFlagInfo.Status = "Failed" $TraceFlagInfo.Notes = $_.Exception.Message $TraceFlagInfo Stop-Function -Message "Failure" -ErrorRecord $_ -Target $server -Continue } $TraceFlagInfo.Status = "Successful" $TraceFlagInfo } } } } |
