  1. Mar 23, 2011  How can we improve Azure Cloud Services (Web and Worker Role)? (Web and Worker Role) Provide a way to schedule worker roles so they only run when needed If worker roles could be scheduled, like windows task scheduler then we would massively reduce the required cpu time used. Where you need N compute nodes NOW and you cant wait to spin.

Missing DLLs or dependencies

Dispatcher And Worker Nodes In Dmg Azure Server

Unresponsive roles and roles that are cycling between Initializing, Busy, and Stopping states can be caused by missing DLLs or assemblies. Install turbotax 2018 mac no dmg.

Symptoms of missing DLLs or assemblies can be:

Dispatcher And Worker Nodes In Dmg Azure Software

  • Your role instance is cycling through Initializing, Busy, and Stopping states.
  • Your role instance has moved to Ready but if you navigate to your web application, the page does not appear.

There are several recommended methods for investigating these issues.

Diagnose missing DLL issues in a web role

When you navigate to a website that is deployed in a web role, and the browser displays a server error similar to the following, it may indicate that a DLL is missing.

Diagnose issues by turning off custom errors

More complete error information can be viewed by configuring the web.config for the web role to set the custom error mode to Off and redeploying the service.

To view more complete errors without using Remote Desktop:

  1. Open the solution in Microsoft Visual Studio.

  2. In the Solution Explorer, locate the web.config file and open it.

  3. In the web.config file, locate the system.web section and add the following line:

  4. Save the file.

  5. Repackage and redeploy the service.

Can i use dmg instead of install disk. Once the service is redeployed, you will see an error message with the name of the missing assembly or DLL.

Diagnose issues by viewing the error remotely

You can use Remote Desktop to access the role and view more complete error information remotely. Use the following steps to view the errors by using Remote Desktop:

  1. Ensure that Azure SDK 1.3 or later is installed.
  2. During the deployment of the solution by using Visual Studio, enable Remote Desktop. For more information, see Enable Remote Desktop Connection for a Role in Azure Cloud Services using Visual Studio.
  3. In the Microsoft Azure portal, once the instance shows a status of Ready, remote into the instance. For more information on using the remote desktop with Cloud Services, see Remote into role instances.
  4. Sign in to the virtual machine by using the credentials that were specified during the Remote Desktop configuration.
  5. Open a command window.
  6. Type IPconfig.
  7. Note the IPV4 Address value.
  8. Open Internet Explorer.
  9. Type the address and the name of the web application. For example, http://<IPV4 Address>/default.aspx.

Navigating to the website will now return more explicit error messages:

  • Server Error in '/' Application.
  • Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
  • Exception Details: System.IO.FIleNotFoundException: Could not load file or assembly ‘Microsoft.WindowsAzure.StorageClient, Version=1.1.0.0, Culture=neutral, PublicKeyToken=31bf856ad364e35’ or one of its dependencies. The system cannot find the file specified.

For example:

Diagnose issues by using the compute emulator

You can use the Microsoft Azure compute emulator to diagnose and troubleshoot issues of missing dependencies and web.config errors.

For best results in using this method of diagnosis, you should use a computer or virtual machine that has a clean installation of Windows. To best simulate the Azure environment, use Windows Server 2008 R2 x64.

  1. Install the standalone version of the Azure SDK.
  2. On the development machine, build the cloud service project.
  3. In Windows Explorer, navigate to the bindebug folder of the cloud service project.
  4. Copy the .csx folder and .cscfg file to the computer that you are using to debug the issues.
  5. On the clean machine, open an Azure SDK Command Prompt window and type csrun.exe /devstore:start.
  6. At the command prompt, type run csrun <path to .csx folder> <path to .cscfg file> /launchBrowser.
  7. When the role starts, you will see detailed error information in Internet Explorer. You can also use standard Windows troubleshooting tools to further diagnose the problem.

Diagnose issues by using IntelliTrace

Nodes

For worker and web roles that use .NET Framework 4, you can use IntelliTrace, which is available in Microsoft Visual Studio Enterprise.

Follow these steps to deploy the service with IntelliTrace enabled:

Dispatcher And Worker Nodes In Dmg Azure Portal

  1. Confirm that Azure SDK 1.3 or later is installed.
  2. Deploy the solution by using Visual Studio. During deployment, check the Enable IntelliTrace for .NET 4 roles check box.
  3. Once the instance starts, open the Server Explorer.
  4. Expand the AzureCloud Services node and locate the deployment.
  5. Expand the deployment until you see the role instances. Right-click on one of the instances.
  6. Choose View IntelliTrace logs. The IntelliTrace Summary will open.
  7. Locate the exceptions section of the summary. If there are exceptions, the section will be labeled Exception Data.
  8. Expand the Exception Data and look for System.IO.FileNotFoundException errors similar to the following:

Address missing DLLs and assemblies

Dispatcher And Worker Nodes In Dmg Azure Server

To address missing DLL and assembly errors, follow these steps:

  1. Open the solution in Visual Studio.
  2. In Solution Explorer, open the References folder.
  3. Click the assembly identified in the error.
  4. In the Properties pane, locate Copy Local property and set the value to True.
  5. Redeploy the cloud service.

Once you have verified that all errors have been corrected, you can deploy the service without checking the Enable IntelliTrace for .NET 4 roles check box.
