Configuring a Workflow on a Farm

You can use a SharePoint solution package to install Microsoft Project Server 2010 workflows on production servers in a SharePoint farm. You can separately activate a workflow for each instance of Project Web App.

Note Note

There will be several tools for workflows available for Project Server 2010. The tools help to create simple (non-branching) workflows, import and export enterprise project types (EPTs), associate EPTs with workflows, and visualize workflows on Project Server. The tools will be published on MSDN Code Gallery (http://code.msdn.microsoft.com/).

The procedures in this article use the BranchingWorkflow sample described in How to: Create a Branching Workflow. You should install and test workflows on a test installation of Project Server before deploying them to a production server. For more information, see How to: Install and Test a Project Server Workflow.

This article includes the following sections:

By using Microsoft Visual Studio 2010, you can easily create a SharePoint solution package (.wsp file) for a Project Server workflow. When you develop a workflow, Visual Studio 2010 creates the Features and Package folders in the workflow project (Figure 1). The Features folder includes the default Feature1 feature.

Note Note

The top-level folder structure includes the Features folder and the Package folder, which contain the SharePoint Feature and package definitions. Because Visual Studio 2010 uses the folder structure to match SharePoint directories on the target computer and to build SharePoint solution files, the top-level folder structure should not be changed.

Procedure 1. To create a workflow solution package

  1. On a Project Server computer, run Visual Studio 2010 as an administrator, and then open a Project Server workflow solution. For example, open the BranchingWorkflow solution.

    Tip Tip

    You can open a workflow solution and create a SharePoint solution package on another Project Server computer, where Visual Studio 2010 is not configured with the Project Server – Workflow and SharePoint Server – Workflow tabs in the Toolbox, as described in How to: Configure Visual Studio 2010 for a Project Server Workflow. The workflow activities in the Toolbox tabs are necessary only if you need to add an activity.

  2. Optional:   Modify the feature title, description, or name:

    1. Expand the Features folder. Right-click Feature1, and then click View Designer.

    2. On the Feature1.feature tab, the default description in the Description text box is My SharePoint Workflow Feature. For example, change the description to Branching Workflow example for testing, and then save and close the Feature Designer.

    3. You can also rename the default Feature1 feature. For example, right-click Feature1 in Solution Explorer, and then click Rename. When you rename the Feature1 node, Visual Studio also renames the subnodes. The code in this article uses the Feature1 name.

  3. Optional:   Add items to the package manifest. For example, add images or icons that can be used in the enterprise project type (EPT) drop-down list or the Project Web App site collection feature list:

    1. In Solution Explorer, right-click the BranchingWorkflow project, click Add, and then click SharePoint Mapped Folder.

    2. In the Add SharePoint Mapped Folder dialog box, expand the TEMPLATE folder, and then click IMAGES. Click OK.

    3. In Solution Explorer, right-click the IMAGES1 folder, click Add, click Existing Item, and then navigate to the directory that contains the images you want to import. For example, import P14SDK.gif and P14SDK_small.gif from the Project Server 2010 SDK download.

  4. Verify the package contents before building the package file:

    1. In Solution Explorer, expand the Package folder, and then double-click the Package.package node to open the Package Designer (Figure 1).

    2. Leave the Reset Web Server check box clear. It is not necessary to restart IIS when you first install the package. When you upgrade the package, you can restart the Project Server Queue service, restart the SharePoint Timer service, and reset IIS manually or by using a script.

      Figure 1. Using the Package Designer in Visual Studio 2010

      Using the Package Designer in Visual Studio 2010
    3. On the Package.package tab, if you imported any images, verify that the package includes the IMAGES1 (BranchingWorkflow) item and the image files.

    4. At the bottom of the Package.package tab, click Manifest. In Preview of Packaged Manifest, verify that the manifest includes the workflow assembly and deployment target, any optional template files you added, and the feature manifest. For example, the BranchingWorkflow manifest that includes the two optional image files shows the following.

      <Solution xmlns="http://schemas.microsoft.com/sharepoint/" 
          SolutionId="57e93e21-e17f-4bfa-8630-b0dde64ea029" SharePointProductVersion="14.0">
        <Assemblies>
          <Assembly Location="BranchingWorkflow.dll" DeploymentTarget="GlobalAssemblyCache" />
        </Assemblies>
        <TemplateFiles>
          <TemplateFile Location="IMAGES\P14SDK.gif" />
          <TemplateFile Location="IMAGES\P14SDK_small.gif" />
        </TemplateFiles>
        <FeatureManifests>
          <FeatureManifest Location="BranchingWorkflow_Feature1\Feature.xml" />
        </FeatureManifests>
      </Solution>
      

      When you install the workflow package on another Project Server computer, you need to know the feature manifest location, for example, BranchingWorkflow_Feature1.

  5. Build the solution package file. In Solution Explorer, right-click the BranchingWorkflow project, and then click Package.

  6. Optional:   Verify the contents of the BranchingWorkflow.wsp file:

    1. In the bin\Debug subfolder of the Visual Studio solution, make a copy of the BranchingWorkflow.wsp file.

    2. Change the file extension to .cab, and then open BranchingWorkflow_Copy.cab by using WinZip. Table 1 shows the files and subdirectories in the package.

      Table 1. Files and directories in the workflow solution package

      Name

      Path

      BranchingWorkflow.dll

       

      manifest.xml

       

      Feature.xml

      BranchingWorkflow_Feature1\

      Elements.xml

      BranchingWorkflow_Feature1\BranchingWorkflow\

      (optional image files)

      images\

Note Note

The Feature1.Template.xml file in the Visual Studio solution shows that the Feature element is missing the Id attribute. However, when you run the Package command, Visual Studio adds the required attributes for the Feature element when it creates the Feature.xml file.

The generated Feature.xml file that is in the BranchingWorkflow.wsp solution package includes the Id attribute and Scope attribute of the Feature element:

<?xml version="1.0" encoding="utf-8"?>
<Feature xmlns="http://schemas.microsoft.com/sharepoint/" Title="BranchingWorkflow Feature1" 
Description="Branching Workflow example for testing" Id="6de058f5-92bb-4c32-82f3-ac1e1841f89b" Scope="Site">
  <Properties>
    <Property Key="GloballyAvailable" Value="true" />
  </Properties>
  <ElementManifests>
    <ElementManifest Location="BranchingWorkflow\Elements.xml" />
  </ElementManifests>
</Feature>

The BranchingWorkflow.wsp file can be copied to other Project Server computers for installation.

You can use Windows PowerShell commands to install and update a workflow solution package in a Project Web App site collection. You must install the package for each instance of Project Web App where you want the workflow to be available.

Procedure 2 shows the individual Windows PowerShell commands required to install the workflow. For a script that installs, removes, or updates a workflow package, see the Complete Script Example for Managing a Workflow Solution section.

Procedure 2. To install a workflow solution package

  1. Copy the workflow package to another Project Server computer. For example, create the PSScripts file share on the ServerName computer, and then copy BranchingWorkflow.wsp to \\ServerName\PSScripts.

  2. On the Windows Start menu on the ServerName computer, click the Microsoft SharePoint 2010 Products folder, right-click SharePoint 2010 Management Shell, and then click Run as administrator.

    Tip Tip

    If you want to edit a script or run SharePoint cmdlets in the Windows PowerShell integrated scripting environment (ISE), you must register the SharePoint snap-in in the current ISE session or add the following command to one of the Windows PowerShell profiles. For information about creating and modifying a profile, see Windows PowerShell Profiles in Windows PowerShell Help, and then add the command to the profile (commands are not case-sensitive).

    The following command is not necessary in the SharePoint 2010 Management Shell; it already has the SharePoint snap-in added.

    Add-PSSnapin Microsoft.SharePoint.PowerShell; Get-PSSnapin
    
  3. Run the following command, which imports the solution to the SharePoint farm:

    Add-SPSolution -LiteralPath C:\PSScripts\BranchingWorkflow.wsp
    

    For more information about the Add-SPSolution cmdlet, for example, type Get-Help Add-SPSolution in the Windows PowerShellcommand window.

    TipTip

    When you run the command in the SharePoint 2010 Management Shell window, you are asked to confirm the action. To suppress the confirmation, add the -Confirm:$false argument to the command.

  4. The following command installs the solution in the Project Web App site collection:

    Install-SPSolution -Identity BranchingWorkflow.wsp -GacDeployment
    
    NoteNote

    The Install-SPSolution command starts a SharePoint Timer process. If the install process is not complete, the Enable-SPFeature command in the following step shows an error.

  5. The following command enables the workflow in the Project Web App site collection that is named pwa on the ServerName computer:

    Enable-SPFeature -Identity BranchingWorkflow_Feature1 -Url http://ServerName/pwa
    

    The Enable-SPFeature command activates the feature. To see the results, click Site collection features on the Project Web App Site Settings page. The Features page (http://ServerName/PWA/_layouts/ManageFeatures.aspx?Scope=Site) shows that BranchingWorkflow Feature1 is active.

  6. To enable Project Web App to create workflow instances, open Site Settings in Project Web App, click Workflow Settings, and then click Add a workflow. Alternately, you can open the Add a Workflow page with the following script:

    $ie = 'C:\Program Files (x86)\Internet Explorer\iexplore.exe'
    & $ie "http://ServerName/pwa/_layouts/AddWrkfl.aspx"
    
  7. On the Add a Workflow page, click the BranchingWorkflow – BranchingWorkflow template, type Branching Workflow for the name, and then click OK.

The Branching Workflow example is now ready for use in Project Web App. To create an EPT and use the workflow, see the procedures in How to: Install and Test a Project Server Workflow.

Installation of the workflow solution adds files in the following places:

  • The Feature.xml and Elements.xml files are installed in the [Program Files]\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\FEATURES\ directory. The example creates the BranchingWorkflow_Feature1 subdirectory.

  • The optional images are installed in the [Program Files]\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\IMAGES\BranchingWorkflow\ directory.

  • The BranchingWorkflow.dll assembly is installed in the global assembly cache. See [Windows]\assembly.

The Windows PowerShell cmdlets that are used to uninstall a solution package are the opposite of the cmdlets for installation, and performed in reverse order.

Procedure 3. To uninstall a workflow solution package

  1. Disable the workflow feature with the following command:

    Disable-SPFeature -Identity BranchingWorkflow_Feature1 -Url http://ServerName/pwa
    

    The Disable-SPFeature command deactivates the feature. To see the results (Figure 2), click Site collection features on the Project Web App Site Settings page to open the Features page (http://ServerName/PWA/_layouts/ManageFeatures.aspx?Scope=Site).

    Figure 2. The Features page shows the BranchingWorkflow Feature1 is not active

    The BranchingWorkflow Feature1 is not active
  2. Uninstall the solution, as follows:

    Uninstall-SPSolution -Identity BranchingWorkflow.wsp
    
  3. Remove the solution:

    Remove-SPSolution -Identity BranchingWorkflow.wsp
    
    NoteNote

    The Uninstall-SPSolution command starts a SharePoint Timer process. If the uninstall process is not complete, the Remove-SPFeature command shows the following error:

    Remove-SPSolution : The solution "branchingworkflow.wsp" has been deployed in the farm. Please retract the deployment before removing the solution. You can also use the -override parameter to forcibly remove the solution, but you will not be able to retract the solution deployment.

  4. To disable Project Web App from creating workflow instances, open Site Settings in Project Web App, click Workflow Settings, and then click Remove a workflow. Alternately, you can open the Remove a Workflow page by using the following script:

    $ie = 'C:\Program Files (x86)\Internet Explorer\iexplore.exe'
    & $ie "http://ServerName/pwa/_layouts/RemWrkfl.aspx"
    
  5. On the Remove a Workflow page, click the Remove option button for the BranchingWorkflow – BranchingWorkflow template, and then click OK.

The files are uninstalled from the three locations previously described.

Complete Script Example for Managing a Workflow Solution

The Install-PJWorkflow.ps1 script can install, remove, or update a workflow. Copy and save the script in a file named Install-PJWorkflow.ps1, for example in the C:\PSScripts directory. To run or edit the script in the Windows PowerShell ISE editor, see the tip in step 2 of Procedure 2.

To use the script, run SharePoint 2010 Management Shell as an administrator. For example, run the following commands to install the BranchingWorkflow.wsp package on the local Project Server computer. The backtick character (grave accent or ASCII 96) in the Install-PJWorkflow command is an escape character for line continuation.

cd C:\PSScripts
.\Install-PJWorkflow E:\Project\WorkflowExamples\BranchingWorkflow.wsp `
   http://ServerName/pwa BranchingWorkflow_Feature1 install

Because the arguments are named parameters, you can also use parameter names in the command. The following example uses the –action named parameter:

.\Install-PJWorkflow E:\Project\WorkflowExamples\BranchingWorkflow.wsp `
   http://ServerName/pwa BranchingWorkflow_Feature1 -action install
Caution noteCaution

The Install-PJWorkflow.ps1 script works if the workflow feature is active only on the Project Web App site that you specify. If there are two or more sites in the SharePoint farm where the workflow is active, you must deactivate the feature on both sites before you retract the solution.

The Start-Sleep cmdlet uses the $sleepTime variable to set a sleep time of five seconds between some of the commands. The Install-SPSolution and Uninstall-SPSolution cmdlets start a SharePoint timer job. If the timer job is not complete, you get an error message when you run Enable-SPFeature or Remove-SPSolution. The script finds the timer job and waits for it to complete.

If Windows Internet Explorer is not installed on the C: drive, change the value of the $ie variable.

Completed update of BranchingWorkflow.wsp

Instead of recreating a workflow solution package and running the Install-PJWorkflow.ps1 script on a Project Server computer, you can update the workflow by manually replacing the assembly in the global assembly cache. You can also use Visual Studio 2010 to deploy and retract the workflow on the development computer.

Important note Important

If you use Visual Studio 2010 to deploy and retract a workflow, you must create a custom deployment that resets the SharePoint Timer service and the Project Server Queue service. For more information, see Walkthrough: Creating a Custom Deployment Step for SharePoint Projects.

We recommend that you use Install-PJWorkflow.ps1 or a similar Windows PowerShell script to install, remove, or update a workflow for Project Web App.

Procedure 4. To manually update a workflow assembly

  1. Stop the Project Server Queue service and the SharePoint Timer service.

  2. Add the updated workflow assembly to the global assembly cache. For example, open the Run dialog box on the Start menu, and then type assembly in the Open text box. Drag BranchingWorkflow.dll into the assembly window.

  3. Start the Project Server Queue service and the SharePoint Timer service.

  4. Restart IIS. In a Command Prompt window, run iisreset.

  5. Repeat steps 1 – 4 for every Project Web App server in the SharePoint farm.

On a SharePoint farm that includes a computer running Project Server and one or more Project Web App servers, the front-end web service on the Project Server computer can be turned off for performance or security reasons. In that case, workflows cannot start until the workflow configuration settings on a separate Project Web App server are updated. Procedure 5 shows how to turn off the front-end web service and update the workflow configuration settings.

Note Note

Procedure 5 is not necessary if you use the Project Server computer also as a front-end Project Web App server.

Procedure 5. To reconfigure a workflow on a farm

  1. Turn off Project Web App (the front-end web service) on the Project Server computer. On the Central Administration page for SharePoint 2010, in the System Settings group, click Manage services on server. On the Services on Server page, click Stop for the Microsoft SharePoint Foundation Web Application service.

    Note Note

    Leave the Project Application Service running on the Project Server computer.

  2. On a separate Project Web App server, open a SharePoint 2010 Management Shell window, and then run the following Windows PowerShell commands:

    $webapp = Get-SPWebApplication -identity http://WebApplication[:port]
    $webapp.UpdateWorkflowConfigurationSetttings()
    

    For example, if the URL of a Project Web App site is http://ServerName/pwa, the –identity parameter is http://ServerName.

  3. On each Project Web App server in the farm, do the following:

    1. Restart Internet Information Services (IIS).

    2. Open the Services window, and then restart Microsoft Project Server Events Service 2010 and Microsoft Project Server Queue Service 2010.
