• SQL Server PowerShell Provider And PowerShell Version 2 Get-Command Issue

  - by BuckWoody

  The other day I blogged that the version of the SQL Server PowerShell provider (sqlps) follows the version of PowerShell. That’s all goodness, but it has appeared to cause an issue for PowerShell 2.0. the Get-Command PowerShell command-let returns an error (Object reference not set to an instance of an object) if you are using PowerShell 2.0 and sqlps – it’s a known bug, and I’m happy to report that it is fixed in SP2 for SQL Server 2008 – something that will released soon. You can read more about this issue here: http://connect.microsoft.com/SQLServer/feedback/details/484732/sqlps-and-powershell-v2-issues Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• SQL Server PowerShell Provider follows the Version of PowerShell on the Host and other errata

  - by BuckWoody

  There may be some misunderstanding on how the PowerShell Provider for SQL Server works. I’ve written an article or two explaining that you can use PowerShell with SQL Server, without having the SQL Server 2008 (or higher) provider around. After all, PowerShell just uses .NET, and SQL Server “Server Management Objects” or SMO listen to that interface as well. In SQL Server 2008 and higher we created a “MiniShell” for PowerShell that gives you the ability to treat a SQL Server Instance as a drive (called a “Provider” or path or drive) and a few commands (called command-lets). Using these two simple constructs you can move around SQL Server quickly and work with the objects it holds. I read the other day where someone stated that we had “re-compiled” PowerShell, so that you would have version 1.0 from SQL Server and 2.0 on your new server. Not so! Drop to a SQLPS prompt and a PowerShell prompt and type this in each: $PSVersionTable They should return the same value. You can think of a MiniShell as simply a compiled “profile” that gives you those providers and command-lets automatically – that’s all. In fact, you can load the SMO libraries yourself without the SQL Server 2008 Provider anywhere in sight. I do this all the time, since the MiniShell also has other restrictions. Also remember that if you run a PowerShell script as a SQL Agent Job step type (in 2008 and higher) that you’re running under the context of the account that starts Agent – I think most folks know this, but it’s good to keep in mind. There’s a re-written section of Books Online that goes over working with this very nicely – also covers the question “How to I connect to another server using the SQL Server PowerShell Provider” (hint: It’s just CD) and “How do I load all the SMO stuff if I don’t want to use the Provider” and more. Be sure and check out the note at the bottom that explains the firewall exceptions you’ll need to enable to CD to that remote server.

• "powershell has stopped working" on PS exit after creating IIS User

  - by Nick Jones

  On a Windows Server 2012 box, I'm using PS to create a new IIS User (for automated deployments using MSDeploy). The command itself appears to work fine -- the user is created -- but as soon as I exit my PowerShell session (typing exit or just closing the command window), a dialog is displayed stating "powershell has stopped working", with the following details: Problem signature: Problem Event Name: PowerShell NameOfExe: powershell.exe FileVersionOfSystemManagementAutomation: 6.2.9200.16628 InnermostExceptionType: Runtime.InteropServices.InvalidComObject OutermostExceptionType: Runtime.InteropServices.InvalidComObject DeepestPowerShellFrame: unknown DeepestFrame: System.StubHelpers.StubHelpers.GetCOMIPFromRCW ThreadName: unknown OS Version: 6.2.9200.2.0.0.400.8 Locale ID: 1033 The PS commands in question are: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Management") [Microsoft.Web.Management.Server.ManagementAuthentication]::CreateUser("Foo", "Bar") Why is this happening and how can I avoid it? EDIT: I've also confirmed this be a problem with PowerShell 4.0, so I've added that tag. I've also submitted it on Connect. UPDATE: It appears that Windows Server 2012 R2 does not have this same bug.

• How to write PowerShell code part 4 (using loop)

  - by ybbest

  In this post, I’d like to show you how to loop through the xml element. I will use the list data deletion script as an example. You can download the script here. 1. To perform the loop, I use foreach in powershell. Here is my xml looks like <?xml version="1.0" encoding="utf-8"?> <Site Url="http://workflowuat/npdmoc"> <Lists> <List Name="YBBEST Collaboration Areas" Type="Document Library"/> <List Name="YBBEST Project" /> <List Name="YBBEST Document"/> </Lists> </Site> 2. Here is the PowerShell to manipulate the xml. Note, you need to get to the $configurationXml.Site.Lists.List variable rather than $configurationXml.Site.Lists foreach ($list in $configurationXml.Site.Lists.List){ AppendLog "Clearing data for $($list.Name) at site $weburl" Yellow if($list.Type -eq "Document Library"){ deleteItemsFromDocumentLibrary -Url $weburl -ListName $list.Name }else{ deleteItemsFromList -Url $weburl -ListName $list.Name } AppendLog "Data in $($list.Name) at $weburl is cleared" Green } How to write PowerShell code part 1 How to write PowerShell code part 2 How to write PowerShell code part 3 How to write PowerShell code part 4

• Powershell, Task Scheduler or loop and sleep

  - by Paddy Carroll

  I have a job that needs to go off every minute or so, it loads a DLL i have written in C# that retrieves state for an SQL Server Mirror (Primary, Mirror and witness) for a number of databases; it allows us to poke DNS to show where the primary instances are. Please don't mention Clustering - We're not doing that. I can't be arsed to write a service, there simply isn't enough time do I Task Scheduler - every minute: Invoke a powershell script that loads the DLL does the business Task scheduler - At Startup : Invoke a similer powershell script that loads the DLL once but then loops and sleeps, refreshing the Object that the DLL exposes. Pros and cons?

• How to write PowerShell code part 1 (Using external xml configuration file)

  - by ybbest

  In this post, I will show you how to use external xml file with PowerShell. The advantage for doing so is that you can avoid other people to open up your PowerShell code to make the configuration changes; instead all they need to do is to change the xml file. I will refactor my site creation script as an example; you can download the script here and refactored code here. 1. As you can see below, I hard code all the variables in the script itself. $url = "http://ybbest" $WebsiteName = "Ybbest" $WebsiteDesc = "Ybbest test site" $Template = "STS#0" $PrimaryLogin = "contoso\administrator" $PrimaryDisplay = "administrator" $PrimaryEmail = "[email protected]" $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers" 2. Next, I will show you how to manipulate xml file using PowerShell. You can use the get-content to grab the content of the file. [xml] $xmlconfigurations=get-content .\SiteCollection.xml 3. Then you can set it to variable (the variable has to be typed [xml] after that you can read the content of the xml content, PowerShell also give you nice IntelliSense by press the Tab key. [xml] $xmlconfigurations=get-content .\SiteCollection.xml $xmlconfigurations.SiteCollection $xmlconfigurations.SiteCollection.SiteName 4. After refactoring my code, I can set the variables using the xml file as below. #Set the parameters $siteInformation=$xmlinput.SiteCollection $url = $siteInformation.URL $siteName = $siteInformation.SiteName $siteDesc = $siteInformation.SiteDescription $Template = $siteInformation.SiteTemplate $PrimaryLogin = $siteInformation.PrimaryLogin $PrimaryDisplay = $siteInformation.PrimaryDisplayName $PrimaryEmail = $siteInformation.PrimaryLoginEmail $MembersGroup = "$WebsiteName Members" $ViewersGroup = "$WebsiteName Viewers"

• How to write PowerShell code part 2 (Using function)

  - by ybbest

  In the last post, I have showed you how to use external configuration file in your PowerShell script. In this post, I will show you how to create PowerShell function and call external PowerShell script.You can download the script here. 1. In the original script, I create the site directly using New-SPSite command. I will refactor it so that I will create a new function to create the site using New-SPSite. The PowerShell function is quite similar to a C# method. You put your function parameters in () and separate each parameter by a comma (,). Then you put your method body in {}. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } 2. The difference is you do not need semi-colon (;) at the end of each statement and when calling the method you do not need comma (,) to separate each parameter. function add ([int] $num1 , [int] $num2){ $total=$num1+$num2 #Return $total $total } #Calling the function [int] $num1=3 [int] $num2=4 $d= add $num1 $num2 Write-Host $d 3. If you like to return anything from the function, you just need to type in the object you like to return, not need to type return .e.g. $ObjectToReturn not return $ObjectToReturn

• PowerShell Script to Deploy Multiple VM on Azure in Parallel #azure #powershell

  - by Marco Russo (SQLBI)

  This blog is usually dedicated to Business Intelligence and SQL Server, but I didn’t found easily on the web simple PowerShell scripts to help me deploying a number of virtual machines on Azure that I use for testing and development. Since I need to deploy, start, stop and remove many virtual machines created from a common image I created (you know, Tabular is not part of the standard images provided by Microsoft…), I wanted to minimize the time required to execute every operation from my Windows Azure PowerShell console (but I suggest you using Windows PowerShell ISE), so I also wanted to fire the commands as soon as possible in parallel, without losing the result in the console. In order to execute multiple commands in parallel, I used the Start-Job cmdlet, and using Get-Job and Receive-Job I wait for job completion and display the messages generated during background command execution. This technique allows me to reduce execution time when I have to deploy, start, stop or remove virtual machines. Please note that a few operations on Azure acquire an exclusive lock and cannot be really executed in parallel, but only one part of their execution time is subject to this lock. Thus, you obtain a better response time also in these scenarios (this is the case of the provisioning of a new VM). Finally, when you remove the VMs you still have the disk containing the virtual machine to remove. This cannot be done just after the VM removal, because you have to wait that the removal operation is completed on Azure. So I wrote a script that you have to run a few minutes after VMs removal and delete disks (and VHD) no longer related to a VM. I just check that the disk were associated to the original image name used to provision the VMs (so I don’t remove other disks deployed by other batches that I might want to preserve). These examples are specific for my scenario, if you need more complex configurations you have to change and adapt the code. But if your need is to create multiple instances of the same VM running in a workgroup, these scripts should be good enough. I prepared the following PowerShell scripts: ProvisionVMs: Provision many VMs in parallel starting from the same image. It creates one service for each VM. RemoveVMs: Remove all the VMs in parallel – it also remove the service created for the VM StartVMs: Starts all the VMs in parallel StopVMs: Stops all the VMs in parallel RemoveOrphanDisks: Remove all the disks no longer used by any VMs. Run this script a few minutes after RemoveVMs script. ProvisionVMs # Name of subscription $SubscriptionName = "Copy the SubscriptionName property you get from Get-AzureSubscription"   # Name of storage account (where VMs will be deployed) $StorageAccount = "Copy the Label property you get from Get-AzureStorageAccount"   function ProvisionVM( [string]$VmName ) {     Start-Job -ArgumentList $VmName {         param($VmName) $Location = "Copy the Location property you get from Get-AzureStorageAccount" $InstanceSize = "A5" # You can use any other instance, such as Large, A6, and so on $AdminUsername = "UserName" # Write the name of the administrator account in the new VM $Password = "Password"      # Write the password of the administrator account in the new VM $Image = "Copy the ImageName property you get from Get-AzureVMImage" # You can list your own images using the following command: # Get-AzureVMImage | Where-Object {$_.PublisherName -eq "User" }         New-AzureVMConfig -Name $VmName -ImageName $Image -InstanceSize $InstanceSize |             Add-AzureProvisioningConfig -Windows -Password $Password -AdminUsername $AdminUsername|             New-AzureVM -Location $Location -ServiceName "$VmName" -Verbose     } }   # Set the proper storage -

• Can't get powershell to return where results from GCI using ACL

  - by Rossaluss

  I'm trying to get Powershell to list files in a directory that are older than a certain date and match a certain user. I've got the below script so far which gives me all the files older than a certain date and lists the directory and who owns them: $date=get-date $age=$date.AddDays(-30) ls '\\server\share\folder' -File -Recurse | ` where {$_.lastwritetime -lt "$age"} | ` select-object $_.fullname,{(Get-ACL $_.FullName).Owner} | ` ft -AutoSize However, when I try and use an additional where parameter to select only files owned by a certain user, I get no results at all, even though I know I should, based on the match I'm trying to obtain (as below): $date=get-date $age=$date.AddDays(-30) ls '\\server\share\folder' -File -Recurse | ` where ({$_.lastwritetime -lt "$age"} -and {{(get-acl $_.FullName).owner} -eq "domain\user"}) | ` select-object $_.fullname,{(Get-ACL $_.FullName).Owner} | ` ft -AutoSize Am I missing something? Can I not use the get-acl command in a where condition as I've tried to? Any help would be appreciated. Thanks

• Virtual Machines List from PowerShell vs PowerShell ISE and PowerGUI

  - by slybloty

  I am confused to why I have different information based on where I try to retrieve it from. I have 3 Windows 2012 servers (G0, G1, and G2) running Hyper-V. The following situation is captured from one server which I use to run scripts and control the others. What I'm trying to do is to get a list of the virtual machines in existence on these 3 machines: Using PowerGUI and PowerShell ISE: PS > Get-VMHost | select name Name ---- G0.nothing.com G2.nothing.com G1.nothing.com PS > Get-VMHost | Get-VM | select name Name ---- VM1628856-4 VM1628856-2 VM1628856-6 VM1628856-3 VM1628856-1 VM1628856-5 Using PowerShell: PS > Get-VMHost | select name Name ---- G0 PS > Get-VM Name State CPUUsage(%) MemoryAssigned(M) Uptime Status ---- ----- ----------- ----------------- ------ ------ VM1107610-1 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1390728-1 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-1 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-10 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-2 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-3 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-4 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-5 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-6 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-7 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-8 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1393540-9 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage VM1833022-1 OffCritical 0 0 00:00:00 Cannot connect to virtual machine configuration storage My main concern is that I don't have reliable information from the 3 tools. The Hyper-V Manager application shows the same list as the PowerShell does. But if I run my scripts from the other two tools, which is what I mostly do, I don't have the same information available, therefore I can't manipulate the same VMs. I've also noticed that the Virtual Machine Manager shows the same list of VMs as the first two tools, PowerGUI and PowerShell ISE. Which information is valid? And how can I retrieve the correct list of VMs? EDIT 1 The $env:psmodulepath value: PS > $env:psmodulepath C:\Users\administrator\Documents\WindowsPowerShell\Modules; C:\Windows\system32\WindowsPowerShell\v1.0\Modules\; C:\Program Files (x86)\Microsoft SQL Server\110\Tools\PowerShell\Modules\; C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\Configuration Providers\; C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\bin\psModules\; C:\Program Files (x86)\QLogic Corporation\QInstaller\Modules EDIT 2 PowerShell is using this Hyper-V module: C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.HyperV.PowerShell\v4.0_6.3.0.0__31bf3856ad364e35\Microsoft.HyperV.PowerShell.dll And PowerGUI is using this one: C:\Windows\System32\WindowsPowerShell\v1.0\Modules\Hyper-V\Hyper-V.psd1 If I try to load the module used by PowerShell onto PowerGUI I still get the same different results. How can I receive the correct information listed under Hyper-V using PowerGUI or PowerShell ISE?

• Load-Module equivalient in PowerShell v1

  - by friism

  (Cross-post from Stackoverflow) For reasons of script portability, I need to dynamically load snap-ins in a PowerShell script (ie. I don't want to actually install it). This is easily accomplished in PowerShell v2 with the Load-Module function. I need to run this particular script on a machine where I, for various reasons, do not want to install PowerShell v2, but have v1. Is there a Load-Module equivalent in PowerShell v1?

• Windows PowerShell ISE doesn't import PSCX 2.0 module

  - by Alexander

  Hi, i am using Powershell 2.0 with the PSCX 2.0 module. When writing PS scripts inside Windows PowerShell ISE no Cmdlets from the PSCX module are availible. For example running "Get-DriveInfo" from Windows PowerShell ISE would cause an error. Running "Get-DriveInfo" from Powershell works fine. I guess Windows PowerShell ISE doesn't load my PS profile (this would be mad). Does anyone know why and what to do to get it work?

  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.

He is a skilled Principal Database Architect, Developer, and Administrator, specializing in SQL Server and Powershell Programming with over 8 years of hands-on experience. He holds a degree in Computer Science, has been awarded a number of certifications (including MCDBA), and is an expert in SQL Server 2000 / SQL Server 2005 / SQL Server 2008 technologies. Let us read the blog post in his own words. I was reading an excellent post from my great friend Pinal about loading data from CSV files, SQL SERVER – Importing CSV File Into Database – SQL in Sixty Seconds #018 – Video,   to SQL Server and was honored to write another guest post on SQL Authority about the magic of the PowerShell. The biggest stuff in TechEd NA this year was PowerShell. Fellows, if you still don’t know about it, it is better to run. Remember that The Core Servers to SQL Server are the future and consequently the Shell. You don’t want to be out of this, right? Let’s see some PowerShell Magic now. To start our tour, first we need to download these two functions from Powershell and SQL Server Master Jedi Chad Miller.Out-DataTable and Write-DataTable. Save it in a module and add it in your profile. In my case, the module is called functions.psm1. To have some data to play, I created 10 csv files with the same content. I just put the SQL Server Errorlog into a csv file and created 10 copies of it. #Just create a CSV with data to Import. Using SQLErrorLog [reflection.assembly]::LoadWithPartialName(“Microsoft.SqlServer.Smo”) $ServerInstance=new-object (“Microsoft.SqlServer.Management.Smo.Server“) $Env:Computername $ServerInstance.ReadErrorLog() | export-csv-path“c:\SQLAuthority\ErrorLog.csv”-NoTypeInformation for($Count=1;$Count-le 10;$count++)  {       Copy-Item“c:\SQLAuthority\Errorlog.csv”“c:\SQLAuthority\ErrorLog$($count).csv” } Now in my path c:\sqlauthority, I have 10 csv files : Now it is time to create a table. In my case, the SQL Server is called R2D2 and the Database is SQLServerRepository and the table is CSV_SQLAuthority. CREATE TABLE [dbo].[CSV_SQLAuthority]( [LogDate] [datetime] NULL, [Processinfo] [varchar](20) NULL, [Text] [varchar](MAX) NULL ) Let’s play a little bit. I want to import synchronously all csv files from the path to the table: #Importing synchronously $DataImport=Import-Csv-Path ( Get-ChildItem“c:\SQLAuthority\*.csv”) $DataTable=Out-DataTable-InputObject$DataImport Write-DataTable-ServerInstanceR2D2-DatabaseSQLServerRepository-TableNameCSV_SQLAuthority-Data$DataTable Very cool, right? Let’s do it asynchronously and in background using PowerShell  Jobs: #If you want to do it to all asynchronously Start-job-Name‘ImportingAsynchronously‘ ` -InitializationScript  {IpmoFunctions-Force-DisableNameChecking} ` -ScriptBlock {    ` $DataImport=Import-Csv-Path ( Get-ChildItem“c:\SQLAuthority\*.csv”) $DataTable=Out-DataTable-InputObject$DataImport Write-DataTable   -ServerInstance“R2D2″`                   -Database“SQLServerRepository“`                   -TableName“CSV_SQLAuthority“`                   -Data$DataTable             } Oh, but if I have csv files that are large in size and I want to import each one asynchronously. In this case, this is what should be done: Get-ChildItem“c:\SQLAuthority\*.csv” | % { Start-job-Name“$($_)” ` -InitializationScript  {IpmoFunctions-Force-DisableNameChecking} ` -ScriptBlock { $DataImport=Import-Csv-Path$args[0]                $DataTable=Out-DataTable-InputObject$DataImport                Write-DataTable-ServerInstance“R2D2″`                               -Database“SQLServerRepository“`                               -TableName“CSV_SQLAuthority“`                               -Data$DataTable             } -ArgumentList$_.fullname } How cool is that? Let’s make the funny stuff now. Let’s schedule it on an SQL Server Agent Job. If you are using SQL Server 2012, you can use the PowerShell Job Step. Otherwise you need to use a CMDexec job step calling PowerShell.exe. We will use the second option. First, create a ps1 file called ImportCSV.ps1 with the script above and save it in a path. In my case, it is in c:\temp\automation. Just add the line at the end: Get-ChildItem“c:\SQLAuthority\*.csv” | % { Start-job-Name“$($_)” ` -InitializationScript  {IpmoFunctions-Force-DisableNameChecking} ` -ScriptBlock { $DataImport=Import-Csv-Path$args[0]                $DataTable=Out-DataTable-InputObject$DataImport                Write-DataTable-ServerInstance“R2D2″`                               -Database“SQLServerRepository“`                               -TableName“CSV_SQLAuthority“`                               -Data$DataTable             } -ArgumentList$_.fullname } Get-Job | Wait-Job | Out-Null Remove-Job -State Completed Why? See my post Dooh PowerShell Trick–Running Scripts That has Posh Jobs on a SQL Agent Job Remember, this trick is for  ALL scripts that will use PowerShell Jobs and any kind of schedule tool (SQL Server agent, Windows Schedule) Create a Job Called ImportCSV and a step called Step_ImportCSV and choose CMDexec. Then you just need to schedule or run it. I did a short video (with matching good background music) and you can see it at: That’s it guys. C’mon, join me in the #PowerShellLifeStyle.

• PowerShell Script to Create PowerShell Profile

  - by Brian Jackett

  Utilizing a PowerShell profile can help any PowerShell user save time getting up and running with their work.  For those unfamiliar a PowerShell profile is a file you can store any PowerShell commands that you want to run when you fire up a PowerShell console (or ISE.)  In my typical profiles (example here) I load assemblies (like SharePoint 2007 DLL), set aliases, set environment variable values (such as max history), and perform other general customizations to make my work easier.  Below is a sample script that will check to see if a PowerShell profile (Console or ISE) exists and create it if not found.  The .ps1 script file version can also be downloaded from my SkyDrive here. Note: if downloading the .ps1 file, be sure you have enabled unsigned scripts to run on your machine as I have not signed mine.   $folderExists = test-path -path $Env:UserProfile\Documents\WindowsPowerShell if($folderExists -eq $false) { new-item -type directory -path $Env:UserProfile\Documents\WindowsPowerShell > $null echo "Containing folder for profile created at: $Env:UserProfile\Documents\WindowsPowerShell" }   $profileExists = test-path -path $profile if($profileExists -eq $false) { new-item -type file -path $profile > $null echo "Profile file created at: $profile" }     A few things to note while going through the above script. $Env:UserProfile represents the personal user folder (c:\documents and settings…. on older OSes like XP and c:\Users… on Win 7) so it adapts to whichever OS you are running but was tested against Windows 7 and Windows Server 2008 R2. “ > $null” sends the command to a null stream.  Essentially this is equivalent to DOS scripting of “@ECHO OFF” by suppressing echoing the command just run, but only for the specific command it is appended to.  I haven’t yet found a better way to accomplish command suppression, but this is definitely not required for the script to work. $profile represent a standard variable to the file path of the profile file.  It is dynamic based on whether you are running PowerShell Console or ISE.   Conclusion     In less than two weeks (Apr. 10th to be exact) I’ll be heading down to SharePoint Saturday Charlotte (SPSCLT) to give two presentations on using PowerShell with SharePoint.  Since I’ll be prepping a lot of material for PowerShell I thought it only appropriate to pass along this nice little script I recently created.  If you’ve never used a PowerShell profile this is a great chance to start using one.  If you’ve been using a profile before, perhaps you learned a trick or two to add to your toolbox.  For those of you in the Charlotte, NC area sign up for the SharePoint Saturday and see some great content and community with great folks.         -Frog Out

• How to Load commands into your powershell profile to run on starting powershell

  - by JohnyV

  Hi, I have found a way to load exchange 2010 powershell into powershell running on a windows xp workstation, however there are a few commands that need to run. I was wondering how I could load them into a profile somehow. These are the commands that I need to run before I can do any of the exchange things such as Get-Mailbox. COMMAND 1 $session = New-PSSession -Configurationname Microsoft.Exchange –ConnectionUri http://servername/powershell -Credential $user (it prompts you for a username and p/word then the next command) COMMAND 2 Import-PSSession $session Then I am able to run exchange 2010 commands such as Get-Mailbox. Anyway I can load these so that when I click on the powershell shortcut they preload the importing of exchange commands. Thanks

• When running PowerShell script as a scheduled task some Exchange 2010 database properties are null

  - by barophobia

  Hello, I've written a script that intends to retrieve the DatabaseSize of a database from Exchange 2010. I created a new AD user for this script to run under as a scheduled task. I gave this user admin rights to the Exchange Organization (as a last resort during my testing) and local admin rights on the Exchange machine. When I run this script manually by starting powershell (with runas /noprofile /user:domain\user powershell) everything works fine. All the database properties are available. When I run the script as a scheduled task a lot of the properties are null including the one I want: DatabaseSize. I've also tried running the script as the domain admin account with the same results. There must be something different in the two contexts but I can't figure out what it is. My script: Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010 Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Starting script" $databases = get-mailboxdatabase -status if($databases -ne $null) { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Object created" $databasesize_text = $databases.databasesize.tomb().tostring() if($databasesize_text -ne $null) { $output = "echo "+$databasesize_text+":ok" Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Path check" if(test-path "\\mon-01\prtgsensors\EXE\") { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Path valid" Set-Content \\mon-01\prtgsensors\EXE\ex-05_db_size.bat -value $output } Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "Exiting program" } else { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "databasesize_text is empty. nothing to do" } } else { Write-EventLog 'Windows PowerShell' -source PowerShell -eventid 100 -message "object not created. nothing to do" } exit 0

• 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

• 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
