function Enable-DbaTraceFlag { <# .SYNOPSIS Enable Global Trace Flag(s) .DESCRIPTION The function will set one or multiple trace flags on the SQL Server instance(s) listed .PARAMETER SqlInstance Allows you to specify a comma separated list of servers to query. .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(s) 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 Author: Garry Bargsley (@gbargsley), http://blog.garrybargsley.com Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Enable-DbaTraceFlag .EXAMPLE Enable-DbaTraceFlag -SqlInstance sql2016 -TraceFlag 3226 Enable the trace flag 3226 on SQL Server instance sql2016 .EXAMPLE Enable-DbaTraceFlag -SqlInstance sql2016 -TraceFlag 1117, 1118 Enable multiple trace flags on SQL Server instance sql2016 #> [CmdletBinding()] param ( [parameter(Position = 0, Mandatory = $true, ValueFromPipeline = $True)] [Alias("ServerInstance", "SqlServer", "SqlServers")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [parameter(Mandatory)] [int[]]$TraceFlag, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { Write-Message -Level Verbose -Message "Attempting to connect to $instance" try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } $CurrentRunningTraceFlags = Get-DbaTraceFlag -SqlInstance $server -EnableException # We could combine all trace flags but the granularity is worth it foreach ($tf in $TraceFlag) { $TraceFlagInfo = [pscustomobject]@{ SourceServer = $server.NetName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName TraceFlag = $tf Status = $null Notes = $null DateTime = [DbaDateTime](Get-Date) } If ($CurrentRunningTraceFlags.TraceFlag -contains $tf) { $TraceFlagInfo.Status = 'Skipped' $TraceFlagInfo.Notes = "The Trace flag is already running." $TraceFlagInfo Write-Message -Level Warning -Message "The Trace flag [$tf] is already running globally." continue } try { $query = "DBCC TRACEON ($tf, -1)" $server.Query($query) $server.Refresh() } catch { $TraceFlagInfo.Status = "Failed" $TraceFlagInfo.Notes = $_.Exception.Message $TraceFlagInfo Stop-Function -Message "Failure" -ErrorRecord $_ -Target $server -Continue } $TraceFlagInfo.Status = "Successful" $TraceFlagInfo } } } } |
