Deploy windows azure worker role
Hi,
I've created a simple azure worker role which executes few things in the database continuously and I need to deploy this worker role to azure portal. how can i deploy an azure worker role to azure portal.
thanks,
Snegha
Hi robdmoore67,
I deployed my worker role using the below option
Deploy using Visual Studio by linking your Visual Studio to your subscription, right-clicking the cloud project and selecting Publish; see this link for more info: http://msdn.microsoft.com/en-us/magazine/jj618299.aspx
deployment went success but my worker role is not running on the background i guess.
this is my below code on workerrole.cs
public override void Run()
// This is a sample worker implementation. Replace with your logic.
Trace.TraceInformation("WorkerRole entry point called", "Information");
while (true)
_myService = new MYService();
_myService .Start();
Trace.TraceInformation("Working", "Information");
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
// For information on handling configuration changes
// see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
return base.OnStart();
but this works fine when i try to debug locally. Kindly let me know if there is any mistake.
kind regards,
Snegha

Velhi Vel,
According to the error message, I suggest you could try to use the latest version of Azure SDK and Emulator. Also, you could refer to this document via (http://msdn.microsoft.com/en-us/library/windowsazure/dn459835.aspx#BKMK_knownIssues ).
You could get the latest version form this page (http://www.windowsazure.com/en-us/downloads/ ).
please try it.

Azure Worker Role can't receive tcp connection to Port 25(Smtp)
I have an SMTPE implementation as an Azure Worker Role. I have defined two input endpoints (port 25 and port 2525). Listener at 2525 accepts tcp connections from smtp clients. However port 25 can't receive connections.
When running on emulator port 25 works fine. This issue occurs when I publish my worker roles to the cloud.
I use the same code for both. InputEndpoints are also defined the same way. The only difference is the port number.
Is there any limitation related to port 25?hi sir,
Base on my experience, Azure platform don't support out-of-the-box mail server. So I am not sure you can use SMTP on Azure cloud service. but I recommend you could refer to the
sendgrid .Also, you can follow this documents:

What happens when Azure Worker Role VM goes down in middle of a computation process
Hi,
I wanted to know what happens if the Azure Fabric controller decides to bring down an Azure Worker Role VM during a computation process within the worker role ? Does the new VM that FC spins up start from the same place where it left off (when the VM
was brought down). As per my understanding, answer is "NO" because an Azure VM is stateless. If we want that the new VM starts from the same place where it left off, we need to save the state and read it from there, when the VM starts (probably
somewhere in the RoleEntryPoint class).
can someone please confirm my understanding ?Hi,
You are right.
Azure PaaS instances are stateless.
If the instance that is just configured were to fail and Azure spun up a replacement instance, all the work that you have done would not carry over.
To know more about it, you might want to refer to the link provided below
http://azure.microsoft.com/en-us/documentation/articles/fundamentals-application-models/
(Refer To Section : Cloud Services )
Hope this helps !

Deploy Files In Azure Worker Role
I have a worker role that uses the MAF framework. That means I need to add assemblies that my project do not reference directly, and these files need to be in a specific folder structure(http://msdn.microsoft.com/en-us/library/bb384201.aspx).
I had the same scenario with a web role and was able to achieve this because when you package a web role, it can copy every file found in the project folder. So I had a BeforeBuild event that would copy all the files to my bin folder for my web app, and all
the files in there were packaged in my azure package.
The same thing does not apply to worker roles. Before the build I create the folder structure in the bin\config folder, I can see the structure there, but the files do not get copied in the azure package at the end. I know the usual way to achieve this is
to add a reference to those dll and set them to copy local, but that won't place the files in the required folder structure.
Another way around would be to add custom code that would load those files from azure storage, and copy them when the role is starting, but that means I need to make extra steps everytime I deploy, and make sure that the storage is updated at the same time
of my package. I was wonedring if there was any other way to achieve this. I cannot believe that this is completely unsupported. I did not create a custom framework for my add-ins, I am usign the one provided by Microsoft with the .NET framework, so I really
hope there is a way to add those files to the azure package.
Thanks, LouisHere is what I dened up doing to achieve this:
Make a copy of the Microsoft.WindowsAzure.targets file found in the MSBuild folder to your Azure project folder. (C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0\Windows Azure Tools\1.6 was the folder for me)
Modify the filed you just copied to comment a part that would delete any "oprhan" file that does not belong to the role it is building. Without removing this, the file will get deleted automatically because it will detect that the project does not need it.
<ItemGroup>
<OrphanedWorkerFiles Include="$(IntermediateWorkerOutputPath)**\*.*" Exclude="@(WorkerFiles->'$(IntermediateWorkerOutputPath)%(TargetPath)')" />
</ItemGroup>
<Delete Files="@(OrphanedWorkerFiles)" ContinueOnError="true" />
That can be found on line 2864 with version 1.6 of the Azure SDK. Comment it out or remove it.
Modify the ccproj file of your Azure project to point to that file instead fo the original one. The import should now look like this: <Import Project="$(ProjectDir)Microsoft.WindowsAzure.targets" />
You can then add a <Target Name="BeforeBuild"></Target> node in that ccproj file, or add before build events in that project that will copy the required file to this folder: $(ProjectDir)obj\$(ConfigurationName)\[Azure role], and replace [Azure
role] by the name of the role you want to copy these files to.
Once you've done that, you can rebuild your solution, and any files copied during your before build event will be included in your final azure package.

I have written a console application to test the WASABi(AutoScaling Application Block) for my worker role running in azure. The worker role processes the messages in the queue and I want to scale-up based on the queue length. I have configured and set the

Hello,
>>: The service configuration could not be retrieved from Windows Azure for hosted service with DNS prefix 'rmsazure' in subscription id **************
Base on error message, I guess your azure service didn't get your certificate and other instances didn't have certificate to auto scale. Please check your upload the certificate on your portal management. Also, you could refer to same thread via link(
http://stackoverflow.com/questions/12843401/azure-autoscaling-block-cannot-find-certificate ).
Hope it helps.
Any question or result, please let me know.
Thanks

Azure Worker Role reboots when adding instance of Web Role
I have a Windows Azure cloud service with a Web Role and a Worker Role. I I have built a website that allows me to perform various management functions against the cloud service (stop/start, reboot instance, add instance, remove instance). All functions are
performed via the web api. My issue is that when I add an instance of the web role, the worker role reboots. Note that this doesn't happen if I add an instance via the Azure portal. The code functions correctly in all other aspects. Any idea how to do this
so that only the role being affected recycles instead of all roles recycling?
My code:
public void AddInstance()
XDocument configDoc = this.GetDeploymentConfiguration();
var ns = configDoc.Root.GetDefaultNamespace();
configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value = ( int.Parse( configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value ) + 1 ).ToString();
string encodedString = Convert.ToBase64String( Encoding.UTF8.GetBytes( configDoc.ToString() ) );
this.SetDeploymentConfig( encodedString );
public XDocument GetDeploymentConfiguration()
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
var xdoc= operation.Invoke( uri );
var myelm = xdoc.Element( wa + "Deployment" ).Element( wa + "Configuration" );
var mystring= Encoding.UTF8.GetString( Convert.FromBase64String( myelm.Value ) );
return XDocument.Parse( mystring );
public string SetDeploymentConfig( string configurationFile )
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "/?comp=config" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
string payloadString = string.Format(
@"<?xml version=""1.0"" encoding=""utf-8""?>
<ChangeConfiguration xmlns=""http://schemas.microsoft.com/windowsazure"">
<Configuration>{0}</Configuration>
</ChangeConfiguration>", configurationFile );
XDocument payload = XDocument.Parse( payloadString );
return operation.Invoke( uri, payload );Hi,
From my experience, if you add one role instance, the whole cloud service will run in translating state, and this cloud service will stop to working, so maybe this is a future request.

What actions will trigger azure worker role reboot
Hi team,
we have a application host in worker role, the worker process will create a new process if it receive a request,
i we want to update the worker and keep new process still working smoothly, what we should do during the Udate.
we did some test for this and found that when updating the worker role via portal, the worker role VM will not reboot,
will all update not cause worker role reboot?
another question, what actions will cause worker role reboot,so that we could avoid them when doing update.
thanks in advance.Hi,
Thanks for Posting. I see that no one in the forum community has answered the question. hope the following resource points you in the right direction.
There are certain implicit and explicit factors that may force the runtime to reboot or re-launch the role instances. Implicit factors are internal to Azure environment and explicit factors are those that are initiated through the change in configuration
files or by performing an in-place upgrade.

Azure worker role throws after EF/Odata Nuget upgrades

Deploying Windows Azure Cloud Service to multiple instances
Hello folks,
Currently, I have Windows Azure Cloud service on one instance, if I move to multiple instances, will Azure deploy it to all instances during the time of deployment? Basically, the fact that there are multiple instances behind the Cloud Service will be transparent
to the whole deployment process, is that a correct understanding?
ThanksHi,
From my experience, all the instances in one cloud service were the same, and we just focus on the application and not the infrastructure. Refer to
http://www.windowsazure.com/en-us/services/cloud-services/ for more information.
Best Regards

Installing flash player msi on Azure Worker Role VM
Hi,
Trying to install the flash msi on Azure Wroker role.
Tried the following C# code:
Type type = Type.GetTypeFromProgID("WindowsInstaller.Installer");
Installer installer = (Installer)Activator.CreateInstance(type);
installer.UILevel = MsiUILevel.msiUILevelNone;
installer.EnableLog("voicewarmup", logfile);
installer.InstallProduct(installerpath, "ACTION=INSTALL ACTION=ADMIN
REBOOT=ReallySuppress ALLUSERS=\"\" ");
While locally on the emulator it worked, on the actual VM it failed:

Any idea what "Failed to connect to server. Error: 0x80070005" means ?
10xHi,
I'm not familiar with Azure VMs, and therefore, unfamiliar with Worker Roles in Azure VMs, however, error: 0x80070005 is the standard Microsoft error for Access Denied. Based on the log output you have, the access denied error is being returned when attempting to connect to a server.

Deploy Windows Azure Virtual Machine UnauthorizedAccessException
Hi,
I intended to move my stored vm from the VMM Library to Azure, however I received the following error. Which account is VMM using to access my library?
Error:
StatusCode: Microsoft.SystemCenter.CloudManager.Providers.ProviderException
Error: The server failed to open file
\\Library\StoredVms\VM1\VM1.vhd: Access to the path is denied.
StatusCode: System.UnauthorizedAccessException
Thanks for any advice
John
JohnHi John,
The Copy/Move job runs under the CloudManagerAzureProviderService. In my case this runs under a system account. I checked the share permissions -> added everyone Full Control and added Everyone RX to the security of the library folder.
I also made the service account local administrator but that did not help at first.
This solved my problem :-)
Hope it will fix yours as well

How is a Worker Role hosted?
Hi
How is a worker role hosted in Azure. What process is it in?
I'm thinking of how to test locally or an on premise version. Is the Azure host process simply a windows service?
I'm writing a solution that uses the Service Bus for Window Server 1.1 as my customers all use on-premise servers (at the moment). It would be handy if I could create a worker role for on premise solutions :)
Thanks
GrahamHi Graham,
Thanks for your posting!
Base on my understanding, Azure worker role is used for some services would run in the background to collect, transform, and prepare data. In other words, Azure work role could
executive function to a background processor .
In worker role project, we could see the file named "WorkerRole.cs". The class inherited the "RoleEntryPoint".
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
Trace.TraceInformation("WorkerRole1 entry point called");
while (true)
Thread.Sleep(10000);
Trace.TraceInformation("Working");
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
// For information on handling configuration changes
// see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
return base.OnStart();
When one worker role instance was starting, it could be executed "OnStart()" method firstly. Then in a worker role’s lifecycle is the "Run" method, typically implemented as an infinite loop, such as "While(true) ".
In fact, if the Run method terminated, the instance would be restarted or recycled again. Please see this video (http://channel9.msdn.com/Series/Windows-Azure-Cloud-Services-Tutorials/Introduction-to-Windows-Azure-Worker-Roles-Part-1).
For your question----" Is the Azure host process simply a windows service?", the answer is that one worker role can be one or more than one instance (VM).
And in your scenarios, Worker role could meet your requirement. In VS, Azure SDK support one project template named "Worker role with service bus queue". Please see this documents:
http://msdn.microsoft.com/en-us/library/azure/jj149831.aspx

Hello,
I want to deploy my c++ exe on a worker role. My exe takes 2 argument PathOfinput.txt and PathOfoutput.txt . When I run my web app locally it works And I obtained the output.file in the right path That I already gave it as an argument to my exe.
The problem is when I publish my service on cloud I was not able to locate my output.txt. Do I need to add code to upload output.txt to localstorage account?
Is it possible to run the exe on cloud and use my local computer for the storage of input.txt and output.txt??
I will be grateful if you respond me as soon as possible
thanks.Hi,
As far as I know, we usually not upload file to azure worker role, if the worker role instance scale to two instances or more, we will failed to read these uploaded files, I would suggest you use azure storage to do this.

Jambor

I am asking for feedback on this design. Here is an example user story:
As a group admin on the website I want to be notified when a user in my group uploads a file to the group.
Easiest solution would be that in the code handling the upload, we just directly create an email message in there and send it. However, this seems like it isn't really the appropriate level of separation of concerns, so instead we are thinking to have a separate
worker process which does nothing but send notifications. So, the website in the upload code handles receiving the file, extracting some metadata from it (like filename) and writing this to the database. As soon as it is done handling the file upload it then
does two things: Writes the details of the notification to be sent (such as subject, filename, etc...) to a dedicated "notification" table and also creates a message in a queue which the notification sending worker process monitors. The entire sequence
is shown in the diagram below.
My questions are: Do you see any drawbacks in this design? Is there a better design? The team wants to use Azure Worker Roles, Queues and Table storage. Is it the right call to use these components or is this design unnecessarily complex? Quality attribute
requirements are that it is easy to code, easy to maintain, easy to debug at runtime, auditable (history is available of when notifications were sent, etc...), monitor-able. Any other quality attributes you think we should be designing for?
More info:
We are creating a cloud application (in Azure) in which there are at least 2 components. The first is the "source" component (for example a UI / website) in which some action happens or some condition is met that triggers a second component or "worker"
to perform some job. These jobs have details or metadata associated with them which we plan to store in Azure Table Storage. Here is the pattern we are considering:
Steps:
Condition for job met.
Source writes job details to table.
Source puts job in queue.
Asynchronously:
Worker accepts job from queue.
Worker Records DateTimeStarted in table.
Queue marks job marked as "in progress".
Worker performs job.
Worker updates table with details (including DateTimeCompleted).
Worker reports completion to queue.
Job deleted from queue.
Please comment and let me know if I have this right, or if there is some better pattern. For example sake, consider the work to be "sending a notification" such as an email whose template fields are filled from the "details" mentioned in
the pattern.Hi,
Thanks for your posting.
This development mode can exclude some errors, such as the file upload complete at the same time... from my experience, this is a good choice to achieve the goal.

Jambor
