Workflow : Check the Checkpoint
I was testing some workflow processes the other day and I ran into something I thought was odd and I hope I can explain it well here. The issues is that when you create a workflow, if you do not plan to use the -PSPersist switch when calling the workflow, make sure you spend plenty [...]
Workflow – Persist to Disk
When using workflows it is common to rely on persistence to allow for external interaction and recovery. The PSPersist parameter on a workflow can be used by the end user to ensure recovery. As the creator, you have the ability to control the persistence of each activity with the PSPersist parameter, or by calling CheckPoint-Workflow or Suspend-Workflow at any [...]
Upgrading to Windows Server 2012 GUI mode issue
Much like myself, I assume many of you are going to upgrade many of your Windows 2008 and Windows 2008 R2 system to Windows Server 2012. There is a known issue after the upgrade that may impact you if you start to remove and add back the GUI features noted in this URL. If you [...]
Cleaning your Windows Server 2012 Server of Source Files
If you install Windows Server 2012 (with a GUI) and then remove the GUI features after you have configured your server, most of the source install files are still on your system. To remove the unneeded source files, use the following command:
|
1 |
Get-WindowsFeature -Name * | Where-Object {$_.Installed -eq $False -AND $_.InstallState -eq "Available"} | Uninstall-WindowsFeature |
After this point when installing new roles you will need to specify [...]
My Ideas – System Center Orchestrator vNext
Orchestrator VNext I think it is a no brainer that the next version of Orchestrator should be PowerShell Workflow based. Though the old engine and way would still remain for backwards compatibility. If you think about it, that is exactly what PSWF is and it has a larger base of functions and abilities. PSWF has [...]
PowerShell Workflows -Variables Parallel / Sequence
Parallels and Sequences, are going to work the same when it comes down variables. When we are in these process blocks, we can see all the variables in the workflow scope with no problems the variables are just there. This I think is very cool! You can define variables in your parent workflow scope and [...]
PowerShell Workflow – Using Variables with InLineScripts
Variables in PowerShell Workflows do not act like standard PowerShell in all cases, so you have to watch out for a few things. From what I can tell though if you need a variable you can get one and pass it around the different scopes. First lets go over some generic PowerShell Workflow variables. At first [...]
PowerShell Workflows – A Basic Understanding
Over the next few weeks I will be putting out information on many different aspects of PowerShell Workflows PowerShell Workflows are new in the PowerShell 3.0. Up to this point, the main use of it is to provision new Windows Servers and Services. Today I am going to do my best to explain to you [...]
PowerShell 3 – Get-Command and Intellisense
With PowerShell 3, we get a lot of extra benefits like intellisense and module auto-loading. These benefits seem to come at a cost. When your profile contains things like New-PSDrive and Import-Module, these new features may not work as expected. I for one had 3 different New-PSDrive created in my profile and no less than [...]
PowerShell Profile, Module Path and Autoloading
It is a good time to start reviewing your PowerShell profiles. Many people have been adding a good list of Import-Module command because in PowerShell 2.0, you were required to load any module you needed to use. In PowerShell 3.0. that has all changed. As PowerShell starts up, it will index all of the modules [...]
