Configuration exception when migrating a ASP.NET application to a Azure webrole

by Damiaan Peeters 31. March 2011 01:50

Ok.  I found why I got a configuration exception every time I launched my azure project (in visual studio 2010). 

I have installed Azure Tools 1.4, on my Visual Studio 2010 SP1.

The problem

When I launched the appFabric / Azure Compute Emulator, I got a my visual studio telling my that I he didn’t have any trace or disassembly information. 

The most annoying part of this situation is that my WebRole Entry point wasn’t started neither.

This was the error (cut some path’s out to keep it readable).

System.Configuration.ConfigurationErrorsException was unhandled

Solution

So what does it mean.  If you open up the config file mentioned in the (inner) exception. You might notice this is not a complete configuration file.  For me it was my App.Settings file. 

What I did?  I moved my app.Settings into my Web.config file.  And gone was the error.

I think this is a bug. So, I posted it to Microsoft Connect so you can review it overthere:

Regain administrator access to your SQL EXPRESS 2008 (R2)

by Damiaan Peeters 27. March 2011 23:32

As I described earlier with a plain SQL server loosing access to your own SQL server or database is a very annoying problem.

The Problem

When starting the Azure Compute Emulator I got this error:

Creating database DevelopmentStorageDb20090919...
Cannot create database 'DevelopmentStorageDb20090919' : CREATE DATABASE permission denied in database 'master'.

One or more initialization actions have failed. Resolve these errors before attempting to run the storage emulator again. These errors can occur if SQL Server was installed by someone other than the current user. Please refer to http://go.microsoft.com/fwlink/?LinkID=205140 for more details.

What this error means is:

  • I was using the useDevelopmentStorage=true parameter, so the emulator connects to the default sqlexpress instance (MACHINE\sqlexpress) on the pc. 
  • Once connected, he tried to create a new database

If SQL Express is not installed by the user your are working with.  The current user is NOT a sysadmin and can’t create any databases).  Adding yourself is neither a solution or enabling the SA user as you are not granted access to do so.

The Solution

Launch the “add self to SQL SysAdmin” script created by ward Beattie.

It saves you days of work and searching.

I highly encourage you to DOWNLOAD the script from the original location.  But just for reference and in case the script got deleted or moved, I added the complete script below.

Configuration of MySQL 5.5 on Websitepanel

by Damiaan Peeters 11. March 2011 19:36

So I followed these steps to activate MySQL 5.5 on our websitepanel deployment.

The current version of Websitepanel (1.1.0) doesn’t support Mysql by default.  However, with a few small changes you can get the Mysql version 5.5 to work.

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
<assemblyIdentity name="MySql.Data" publicKeyToken="c567fc88969c44d" />
<bindingRedirect oldVersion="0.0.0.0-6.3.5.0" newVersion="6.3.6.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>

  • Finally add and update the MySQL configuration in website panel.  These where the values I used
    • Internal Address: 127.0.0.1:3306
    • MySQL Installation Folder: C:\Program Files\MySQL\MySQL Server 5.5
    • Database Browser Logon URL: http://phpmyadmin.ourdomain.com/index.php
    • Root login: root
    • Root password: our root password

There is still a bug with deleting the database.  There are solutions available for this problem, but it’s not urgent for me.  So I didn’t tried it.
