Lesson Learned #213: Cannot set the AccessToken property if the Integrated Security has been set
Today, I worked on a service request where using SQLPackage and Azure Active Directory user our customer got the following error message "Error exporting database:Could not connect to database server. Cannot set the AccessToken property if the 'Integrated Security' connection string keyword has been set to 'true' or 'SSPI'."Lesson Learned #523: Measuring Import Time -Parsing SqlPackage Logs with PowerShell
This week I'm working on a service request who was experiencing long import times when restoring a large BACPAC into Azure SQL Database, I need to understand where time was being spent inside SqlPackage.exe. I rely on the diagnostics log and the PowerShell to analyze this time. The file contains valuable information that we can extract and summarize using PowerShell. I developed a small PowerShell Script with the following idea: Classifies every entry (Information, Verbose‑25, Verbose‑19, …). Tracks cumulative time for each class. Flags any operation whose delta exceeds 10 seconds with a warning. Produces two tables at the end: Summary per Level (counts + total seconds). Verbose‑25 Operations sorted by elapsed time. I used Verbose-25 (Verbose Operation plus operation ), because I identified that the lines contains the elapsed-time of the operation done. Those are usually the slowest parts. How the Script Works Read the content 5000 lines at a time. Parser every line running Process‑Line function to obtain 3 variables Level, Id, Timestamp, Message. If the level is not Verbose-25 (operation finished), the time is measured against the previous timestamp otherwise for Perf: text Operation ended we use elapsed ms. I added a line that when the delta > 10 s triggers Write‑Warning. $logPath = "C:\temp\Exampledf.txt" $prevStamp = $null $Salida = $null [int]$Lines= 0 $stats = @{} $Verbose25 = @{} function Process-Line { param ( [string]$line, [ref]$prevStamp ) if ($line -notmatch 'Microsoft\.Data\.Tools\.Diagnostics\.Tracer') { return "" } $tail = $Line.Substring($Line.IndexOf('Tracer') + 6).Trim() $c1 = $tail.IndexOf(':') if ($c1 -lt 0) { return "" } $level = $tail.Substring(0, $c1).Trim() $rest = $tail.Substring($c1 + 1).Trim() $c2 = $rest.IndexOf(':') if ($c2 -lt 0) { return "" } $id = $rest.Substring(0, $c2).Trim() $rest = $rest.Substring($c2 + 1).Trim() if ($rest.Length -lt 19) { return "" } $stamp = $rest.Substring(0, 19) $msg = $rest.Substring(19).Trim() if ($msg.StartsWith(':')) { $msg = $msg.Substring(1).Trim() } If($Level -eq "Verbose") { $levelKey = "$level-$id" # Verbose-25, Verbose-19… } else { $levelKey=$level } $delta = 0 if ($msg -like 'Perf: Operation ended*' -and $Level -eq "Verbose") { # Ej.: "...elapsed in ms): StartImportTable,[schema].[table],58" $elapsedMs = ($msg.Split(',')[-1]).Trim() if ($elapsedMs -match '^\d+$') { $delta = [double]$elapsedMs / 1000 } $Verbose25[$msg] = @{ ElapsedTime = [double]$elapsedMs / 1000 } $prevStamp.Value = [datetime]$stamp } else { $curr = [datetime]$stamp if ($prevStamp.Value) { $delta = ($curr - $prevStamp.Value).TotalSeconds } $prevStamp.Value = $curr } # ---- Update the summary ----------------------------------------------- if (-not $stats.ContainsKey($levelKey)) { $stats[$levelKey] = @{ Count = 0; Total = 0 } } $stats[$levelKey].Count++ $stats[$levelKey].Total += $delta return "$levelKey $delta $($msg.Trim())" } # Read and show line (every 5000) Get-Content -Path $logPath -ReadCount 5000 | ForEach-Object { foreach ($line in $_) { $Lines++ $Salida = Process-Line -line $line -prevStamp ([ref]$prevStamp) if ($Salida) { $deltaToken = [double]($Salida.Split()[1]) if ($deltaToken -gt 10) { Write-Warning "$Lines $Salida" } if ($Lines % 5000 -eq 0 -and $Salida) { Write-Output "$Lines Text: $Salida" } } } } Write-Output "`n--- Summary per Level -----------------------------------------" Write-Output "Lines Read: $Lines" $stats.GetEnumerator() | Sort-Object Name | ForEach-Object { [pscustomobject]@{ Level = $_.Name Operations = $_.Value.Count TotalTimeSec = [math]::Round($_.Value.Total, 3) } } | Format-Table -AutoSize Write-Output "`n--- Verbose-25 Operations -------------------------------------" $Verbose25.GetEnumerator() | Sort-Object @{ Expression = { [double]$_.Value.ElapsedTime }; Descending = $true } | ForEach-Object { [pscustomobject]@{ Operation = $_.Name ElapsedTimeSec = [double]$_.Value.ElapsedTime } } | Format-Table -AutoSize Examples:Lesson Learned #446: Simplifying SQLPackage Log Debugging with PowerShell
Handling massive SQLPackage diagnostic logs, like those spanning over 4 million rows, can be an overwhelming task when troubleshooting support cases. This article introduces a PowerShell script designed to efficiently parse through SQLPackage diagnostic logs, extract error messages, and save them to a separate file, thus simplifying the review process and enhancing the debugging experience.
