RabbitMQ: Completely Hard Reset a RabbitMQ Server Installation

clean-rabbitmq

Probably the most exciting thing of this post is the funny image of RabbitMQ’s cleaner 🙂

Yes, you can also reset the RabbitMQ instance, by running these commands:

rabbitmqctl.bat stop_app

rabbitmqctl.bat reset

rabbitmqctl.bat start_app

soft-reset-rabbitmq

…but sometimes could be necessary to clean up stuff, especially when you have played around cluster, multiple node on the same machine, ad so on.

It took me a while to figure out who was maintaining a reference to the %appdata%\RabbitMQ folder, even after I uninstalled Erlang, so here’s the simple steps:

  1. Uninstall RabbitMQ Server
  2. Kill the process epmd.exe (this was the process maintaning a reference to the RabbitMQ folder)
    rabbitmq-epmd-process
  3. Delete the folder RabbitMQ that is under %appdata%
    rabbitmq-folder-wont-delete If you also want to change the erlang cookie, you will need to delete also the file “.erlang.cookie” that you find under your users folder %userprofile%
    rabbitmq-erlang-cookie If you have a cluster and remove .erlang.cookie the node would no be able to rejoin the cluster
  4. Reinstall RabbitMQ Server

 

That’s all folks!

Software on the hosted build server

Took directly from visual studio site: Hosted build controller.

You can check the detail list, and install the visual studio extension “Avanade Extensions for VS2012” (VS2013 version) to track the software installed on the hosted build server using the Software Inventory functionality.

The hosted build server is deployed with the following software:

  • Windows Server 2012 R2, 64-bit environment, with Windows PowerShell
  • Team Foundation Build (Team Foundation Server 2013)
  • Visual Studio
    • Visual Studio 2013 Update 2 RC

RabbitMQ: Change the Hostname

rabbitmq-change-hostname

WARNING: ALL THE RABBITMQ DATA WILL BE LOST WITH THIS OPERATION. Please backup your rabbitmq database before doing this (check the documentation about).

If you change the name of the machine where RabbitMQ server is installed, you will see that the service will no longer be startable, this because RabbitMQ relays on the machine name to create and connect to the node, even if it is local.

To fix this problem, you just have to reinstall the rabbitmq windows service, by using the proper command line utility rabbitmq-service.bat

*********************
Service control usage
*********************

rabbitmq-service help    - Display this help
rabbitmq-service install - Install the RabbitMQ service
rabbitmq-service remove  - Remove the RabbitMQ service

The following actions can also be accomplished by using
Windows Services Management Console (services.msc):

rabbitmq-service start   - Start the RabbitMQ service
rabbitmq-service stop    - Stop the RabbitMQ service
rabbitmq-service disable - Disable the RabbitMQ service
rabbitmq-service enable  - Enable the RabbitMQ service
  1. First start a command prompt as administrator and go to the rabbitmq-server-x sbin folder 
    cd %programfiles(x86)%\RabbitMQ Server\rabbitmq_server-3.3.2\sbin
  2. Uninstall the service 
    rabbitmq-service.bat remove
  3. Install the service 
    rabbitmq-service.bat install

This should recreate the service and configure it to start the node with the correct name.

If this doesn’t work you can follow the instruction on how to completely reset a rabbitmq server installation.

Developing against Service Bus for Windows 1.1

roysvork

Wouldn’t it be great if we could work on applications that leverage Microsoft Service Bus locally without having to connect to and potentially pay for Microsoft Azure?

Not everyone knows this, but there’s a local counterpart to Microsoft Azure Service Bus in the form of Service Bus for Windows. Those that do know about it know that it doesn’t have a great development story and can be a pain in the arse to set up.

In this post we’ll take the sting out of the process and show you how you can get your local environment set up so you and the rest of your team can develop against Service Bus without using any Microsoft Azure services.

You’ll need an instance of SQL server to which you have admin rights to use Service Bus for Windows.

IMPORTANT: If you have any other service running that use the default AMQP ports 5671, & 5672 then the configuration…

Azure Public IP Addresses

If you like me you’re interested to know the ip ranges that windows azure uses to connect to the internet 🙂 this is the right post 😉

Do not assume that traffic originating from these IP address ranges is trustworthy.

You can download Windows Azure Datacenter IP Ranges xml from the download center.

Here’s the list updated on 12th June 2014

Linq Take Random – Query to Get a Random Sub Collection – Random Order

While writing a load test today, I had to simulate different kind of customers with different kind of taste, and I had a collection of item ids, and to simulate a random distribution, I had to generate a sub collection taking random ids from the collection source, in that way I can simulate different kind of customers that will end-up querying the server requesting different item details.

Googling a little-bit I found an easy way to do this, and is to Order the collection by a different Guid for each row:

var result = collection.OrderBy(t => Guid.NewGuid());

and to get (take) 10 random elements:

var result = collection.OrderBy(t => Guid.NewGuid()).Take(10);

From the Scott Mitchell’s post, you can see some empirical tests that proves a nice random distribution. Of course this is not to use in production code where you absolutely need an unpredictable results, but for load testing, and other take-it-easy purpose, that’s cool.

This is a LINQPad example:

void Main()
{
	var collection = Enumerable.Range(1, 100).ToList();
	
	for (int i = 0; i < 3; i++)
	{
		collection.OrderBy(t => Guid.NewGuid()).Take(10).Dump();
	}
}
