• LiveMeeting VC PowerShell PASS – Troubleshooting SQL Server with PowerShell

  - by Laerte Junior

  Guys, join me on Wednesday July 18th 12 noon EDT (GMT -4) for a presentation called Troubleshooting SQL Server With PowerShell. It will be in English, so please make allowances for this. I’m sure that you’re aware that my English is not perfect, but it is not so bad. I will do my best, you can be sure. The registration link will be available soon from PowerShell.sqlpass.org, so I hope to see you there. It will be a session without slides. Just code; pure PowerShell code. Trust me, We will see a lot of COOL stuff.Big thanks to Aaron Nelson (@sqlvariant) for the opportunity! Here are some more details about the presentation: “Troubleshooting SQL Server with PowerShell – The Next Level’ It is normal for us to have to face poorly performing queries or even complete failure in our SQL server environments. This can happen for a variety of reasons including poor Database Designs, hardware failure, improperly-configured systems and OS Updates applied without testing. As Database Administrators, we need to take precaution to minimize the impact of these problems when they occur, and so we need the tools and methodology required to identify and solve issues quickly. In this Session we will use PowerShell to explore some common troubleshooting techniques used in our day-to-day work as s DBA. This will include a variety of such activities including Gathering Performance Counters in several servers at the same time using background jobs, identifying Blocked Sessions and Reading & filtering the SQL Error Log even if the Instance is offline The approach will be using some advanced PowerShell techniques that allow us to scale the code for multiple servers and run the data collection in asynchronous mode.

• Powershell BitLocker Recovery Key

  - by TheNoobofNoobs

  I'm trying to get a list of all computers that have a bit locker recovery key (or information for that matter) populated in their respective fields in AD. I am unable to even start on a script as I don't know where to begin. I did find this online but it doesn't appear to be working. foreach($comp in get-adcomputer -filter *) { get-adobject -filter 'objectclass -eq "msFVE-RecoveryInformation"' - searchbase $comp.distinguishedname -properties msfve-recoverypassword,whencreated | sort whencreated | select msfve-recoverypassword -last 1 } Export-Csv "FilePath.csv" Any ideas as to how I can go about this.

• An Introduction to PowerShell Modules

  For PowerShell to provide specialised scripting, especially for administering server technologies, it can have the range of Cmdlets available to it extended by means of Snapins. With version 2 there is an easier and better method of extending PowerShell: the Module. These can be distributed with the application to be administered, and a wide range of Cmdlets are now available to the PowerShell user. Powershell has suddenly grown up.

• Running same powershell script multiple asynchronous times with separate runspace

  - by teqnomad

  Hi, I have a powershell script which is called by a batch script which is called by Trap Receiver (which also passes environment variables) (running on windows 2008). The traps are flushed out at times in sets of 2-4 trap events, and the batch script will echo the trap details for each message to a logfile, but the powershell script on the next line of the batch script will only appear to process the first trap message (the powershell script writes to the same logfile). My interpetation is that the defaultrunspace is common to all iterations of the script running and this is why the others appear to be ignored. I've tried adding "-sta" when I invoke the powershell script using "powershell.exe -command", but this didn't help. I've researched and found a method using C# but I don't know this language, and busy enough learning powershell, so hoping to find a more direct solution especially as interleaving a "wrapper" between batch and powershell will involve passing the environment variables. http://www.codeproject.com/KB/threads/AsyncPowerShell.aspx I've hunted through stackoverflow, and again the only question of similar vein was using C#. Any suggestions welcome. Some script background: The powershell script is actually a modification of a great script found at gregorystrike website - cant post the link as I'm limited to one link but its the one for Lefthand arrays. Lots of mods so it can do multiple targets from one .ini file, taking in the environment variables, and options to run portions of the script interactively with winform. But you can see the gist of the original script. The batch script is pretty basic. The keys things are I'm trying to filter out trap noise using the :~ operator, and I tried -sta option to see if this would compartmentalise the powershell script. set debug=off set CMD_LINE_ARGS="%*" set LHIPAddress="%2" set VARBIND8="%8" shift shift shift shift shift shift shift set CHASSIS="%9" echo %DATE% %TIME% "Trap Received: %LHIPAddress% %CHASSIS% %VARBIND8%" >> C:\Logs\trap_out.txt set ACTION="%VARBIND8:~39,18%" echo %DATE% %TIME% "Action substring is %ACTION%" 2>&1 >> C:\Logs\trap_out.txt if %ACTION%=="Remote Copy Volume" ( echo Prepostlefthand_env_v2.9 >> C:\Logs\trap_out.txt c:\Windows\System32\WindowsPowerShell\v1.0\PowerShell.exe -sta -executionpolicy unrestricted -command " & 'C:\Scripts\prepostlefthand_env_v2.9.ps1' Backupsettings.ini ALL" 2>&1 >> C:\Logs\trap_out.txt ) ELSE ( echo %DATE% %TIME% Action substring is %ACTION% so exiting" 2>&1 >> C:\Logs\trap.out.txt ) exit

• SQL SERVER – Powershell – Get a List of Fixed Hard Drive and Free Space on Server

  - by pinaldave

  Earlier I have written this article SQL SERVER – Get a List of Fixed Hard Drive and Free Space on Server. I recently received excellent comment by MVP Ravikanth. He demonstrated that how the same can be done using Powershell. It is very sweet and quick solution. Here is the powershell script. Run the same in your powershell windows. Get-WmiObject -Class Win32_LogicalDisk | Select -Property DeviceID, @{Name=’FreeSpaceMB’;Expression={$_.FreeSpace/1MB} } | Format-Table -AutoSize Well, I ran this script in my powershell window, it gave me following result – very accurately and easily. Thanks Ravikanth one more time for excellent tip.

• Leveraging NuGet as a central repository for PowerShell modules

  - by cibrax

  We have been working a lot lately with PowerShell as part of our star product at Tellago Studios, “Moesion”. One of the main features we provide in Moesion is the ability to execute PowerShell commands remotely in a given server using a web mobile interface (You can read more in my previous post about Moesion). One of the things we realized in all this time is that PowerShell lacks of a central repository where IT guys or we, the developers, can easily grab and reuse commands.  All the commands or modules are basically spread across multiple places or websites, like personal blogs, TechNet or CodePlex projects to name a few making the search of them very hard. You are usually limited to use your favorite search engine and copy what you find. In addition, there is not an easy way to reuse, extend or version these commands, which also limits any contribution that you could make to the community.  My friend Jose wrote a great post the other day about the importance of reusing PowerShell modules, and what is the mechanism to reuse them. Jose, however, based his post in a custom implementation using a GIT repository for storing the modules. We have NuGet in the .NET platform for sharing and reusing existing libraries or code, so why can’t just leverage it for reusing PowerShell modules as well ?. Some teams in Microsoft are using NuGet for distributing libraries and binaries so it would be a great thing for all of us if they also distribute the scripting interfaces in PowerShell using NuGet. This applies to the .NET OS community as well. In fact, it looks like Andrew Nurse had the same idea and implemented a project for this in BitBucket, PsGet.

• powershell v2 remoting - How do you enable unecrypted traffic

  - by Peter Walke

  I'm writing a powershell v2 script that I'd like to run against a remote server. When I run it, I get the error : Connecting to remote server failed with the following error message : The WinRM client cannot process the request. Unencrypted traffic is currently disabled in the client configuration. Change the client configurati on and try the request again. For more information, see the about_ Remote_Troubleshooting Help topic. I looked at the online help for about _ Remote_Troubleshooting, but it didn't point me towards how to enable unecrypted traffic. Below is the script that I'm using that is causing me problems. Note: I have already run Enable-PSRemoting on the remote machine to allow it to accept incoming requests. I have tried to use a session option variable, but it doesn't seem to make any difference. $key = "HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds" Set-ItemProperty $key ConsolePrompting True $tvar = "password" $password = ConvertTo-SecureString -string $tvar -asPlainText –force $username="domain\username" $mySessionOption = New-PSSessionOption -NoEncryption $credential = New-Object System.Management.Automation.PSCredential($username,$password) invoke-command -filepath C:\scripts\RemoteScript.ps1 -sessionoption $mySessionOption -authentication digest -credential $credential -computername RemoteServer How do I enable unencrypted traffic?

• PowerShell: New-PSDrive error handling

  - by mazebuhu

  Hello, I have a script where I mount with the command "New-PSDrive" a network drive. Now, since the script is running as a "cronjob" on a server I want to have some error detection. If for any reason the command New-PSDrive fails the script should stop executing and notify that something went wrong. I have the following code: Try { New-PSDrive -Name A -PSProvider FileSystem -Root \\server\share } Catch { ... handle error case ... } ... other code ... For testing reasons I specified a wrong server name and I get the following error "New-PSDrive : Drive root "\wrongserver\share" does not exist or it's not a folder". Which is OK since the server does not exists. But the script does not go into the Catch clause and stop. It happily continues to run and ends up in a mess since no drive is mounted :-) So my question, why? Is there any difference in Exception handling in PowerShell? I should also note that I'm a noob in PowerShell scripting. Bye, Martin

• SQLAuthority News – Guest Post – Performance Counters Gathering using Powershell

  - by pinaldave

  Laerte Junior Laerte Junior has previously helped me personally to resolve the issue with Powershell installation on my computer. He did awesome job to help. He has send this another wonderful article regarding performance counter for readers of this blog. I really liked it and I expect all of you who are Powershell geeks, you will like the same as well. As a good DBA, you know that our social life is restricted to a few movies over the year and, when possible, a pizza in a restaurant next to your company’s place, of course. So what we have to do is to create methods through which we can facilitate our daily processes to go home early, and eventually have a nice time with our family (and not sleeping on the couch). As a consultant or fixed employee, one of our daily tasks is to monitor performance counters using Perfmom. To be honest, IDE is getting more complicated. To deal with this, I thought a solution using Powershell. Yes, with some lines of Powershell, you can configure which counters to use. And with one more line, you can already start collecting data. Let’s see one scenario: You are a consultant who has several clients and has just closed another project in troubleshooting an SQL Server environment. You are to use Perfmom to collect data from the server and you already have its XML configuration files made with the counters that you will be using- a file for memory bottleneck f, one for CPU, etc. With one Powershell command line for each XML file, you start collecting. The output of such a TXT file collection is set to up in an SQL Server. With two lines of command for each XML, you make the whole process of data collection. Creating an XML configuration File to Memory Counters: Get-PerfCounterCategory -CategoryName "Memory" | Get-PerfCounterInstance  | Get-PerfCounterCounters |Save-ConfigPerfCounter -PathConfigFile "c:\temp\ConfigfileMemory.xml" -newfile Creating an XML Configuration File to Buffer Manager, counters Page lookups/sec, Page reads/sec, Page writes/sec, Page life expectancy: Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Page*" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" –NewFile Then you start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\ConfigfileMemory.xml -PathOutputFile c:\temp\ConfigfileMemory.txt To let the Buffer Manager collect, you need one more counters, including the Buffer cache hit ratio. Just add a new counter to BufferManager.xml, omitting the new file parameter Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Buffer cache hit ratio" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" And start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\BufferManager.xml -PathOutputFile c:\temp\BufferManager.txt You do not know which counters are in the Category Buffer Manager? Simple! Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters Let’s see one output file as shown below. It is ready to bulk insert into the SQL Server. As you can see, Powershell makes this process incredibly easy and fast. Do you want to see more examples?

• C#, Powershell - Microsoft.Exchange.Management.PowerShell.Admin

  - by Svein Erik

  I'm having troubles using the Microsoft.Exchange.Management.PowerShell.Admin on a server. The server is not the one running Exchange 2007, it's a remote server (in the same zone). I can't figure out how to add the Snapin for Powershell - Microsoft.Exchange.Management.PowerShell.Admin. Is it possible to just get the dll file from the Exchange 2007 server, and copy it to the server where my code is running? Can someone please explain what I need to do to get my code running? The exception that i'm getting now is: "No Windows PowerShell Snap-ins are available for version 1". This is the code that generates the error: public void CreateMailBox(User user) { //Create a runspace for your cmdlets to run and include the Exchange Management SnapIn... RunspaceConfiguration runspaceConf = RunspaceConfiguration.Create(); PSSnapInException PSException = null; PSSnapInInfo info = runspaceConf.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.Admin", out PSException); Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConf); runspace.Open(); Pipeline pipeline = runspace.CreatePipeline(); Command command = new Command("New-Mailbox"); command.Parameters.Add("Name", user.UserName); .... The error is coming on the line with PSSnapInfo info = runspaceConf..... I'm using .NET 3.5

  Laerte Junior If you are a Powershell user, the name of the Laerte Junior is not a new name. He is the one man with exceptional knowledge of Powershell. He is not only very knowledgeable, but also very kind and eager to those in need. I have been attempting to setup Powershell for many days, but constantly facing issues. I was not able to get going with this tool. Finally, yesterday I sent email to Laerte in response to his comment posted here. Within 5 minutes, Laerte came online and helped me with the solution. He spend nearly 15 minutes working along with me to solve my problem with installation. And yes, he did resolve it remotely without looking at my screen – What a skilled and exceptional person!! I will soon post a detail note about the issue I faced and resolved with the help of Laerte. Here is his solution to my earlier puzzle in his own words.

• Windows startup Powershell script not closing after Start-Process

  - by Matthew Phipps

  I've got a Powershell V2.0 startup script for my work computer (XP Professional 64-bit), as follows: start "C:\Program Files (x86)\Microsoft Office\Office12\OUTLOOK.EXE" -ArgumentList "/recycle" sleep -S 2 start "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -ArgumentList "https://mail.google.com" sleep -S 2 start "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -ArgumentList "-new-window https://www.google.com/calendar" sleep -S 2 start "C:\Program Files (x86)\Skype\Phone\Skype.exe" The sleeps are to ensure that the windows appear on the taskbar in the correct order. I run this from a shortcut on my Quick Launch with the following Target: C:\WINDOWS\system32\WindowsPowerShell\v1.0\powershell.exe C:\scripts\initialize.ps1 (Yes, this is 2.0: powershell -Version 2.0 works, as does -Version 1.0, but not -Version 3.0) Problem is, the command window stays open until the Firefox windows are closed, which is not what I want. Looking at Process Explorer when I run the script, here's what happens: powershell.exe appears under explorer.exe and the Powershell window appears (with a black background, oddly. But it's not cmd.exe, since when I was debugging the script error messages would appear in red). outlook.exe appears under powershell.exe and the Outlook window appears. firefox.exe appears under powershell.exe and a Firefox window appears. A second firefox.exe appears under powershell.exe and another Firefox window appears. The second Firefox process then exits, as expected, since Firefox only uses one process. skype.exe appears under powershell.exe and the Skype window appears. The powershell.exe process inexplicably sticks around, as does the Powershell window. If I close both Firefox windows, the powershell.exe process exits and the Powershell window closes, and the outlook.exe and skype.exe processes appear under explorer.exe as expected. I suspect this has something to do with Firefox's standard input, output and error: I wouldn't expect Outlook or Skype to ever output anything to the console, but Firefox has command-line options that allow it to do so. I've looked over my about:config's user set values and didn't find anything suspicious. Finally, if I have a firefox.exe instance already running (started from the desktop shortcut) the problem doesn't occur (the powershell.exe process exits as it ought to). So what's going on here? I'm going to try adding -WindowStyle hidden to the shortcut next (gotta close this Firefox to test it), but I want to get to the bottom of this, if only to improve my understanding of how Windows consoles work.

• Use cases of [ordered], the new PowerShell 3.0 feature

  - by Roman Kuzmin

  PowerShell 3.0 CTP1 introduces a new feature [ordered] which is somewhat a shortcut for OrderedDictionary. I cannot imagine practical use cases of it. Why is this feature really useful? Can somebody provide some useful examples? Example: this is, IMHO, rather demo case than practical: $a = [ordered]@{a=1;b=2;d=3;c=4} (I do not mind if it is still useful, then I am just looking for other useful cases). I am not looking for use cases of OrderedDictionary, it is useful, indeed. But we can use it directly in v2.0 (and I do a lot). I am trying to understand why is this new feature [ordered] needed in addition. Collected use cases from answers: $hash = [ordered]@{} is shorter than $hash = New-Object System.Collections.Specialized.OrderedDictionary N.B. ordered is not a real shortcut for the type. New-Object ordered does not work. N.B. 2: But this is still a good shortcut because (I think, cannot try) it creates typical for PowerShell case insensitive dictionary. The equivalent command in v2.0 is too long, indeed: New-Object System.Collections.Specialized.OrderedDictionary]([System.StringComparer]::OrdinalIgnoreCase)
