A partir de hoy existen nuevas características en la Plataforma de SQL Azure (http://blogs.msdn.com/sqlazure/archive/2010/04/16/9997517.aspx):
- MARS (Multiple Active Results Sets), lo cual simplifica el diseño de las aplicaciones y permite trabajar con múltiples conjuntos de datos
- ALTER rename permite renombrar las bases de datos en la nube
- Application and Multi-server management mejoras en las Data-tier Applications lo cual que permite hacer el despliegue de base de datos en SQL Azure de forma más flexible desde SQL Server 2008 R2 y Visual Studio 2010
También puede empezar a probar las bases de 50GB en SQL Azure, para hacerlo envíe un correo a EngageSA@microsoft.com

There are new improvements in the SQL Azure Platform (http://blogs.msdn.com/sqlazure/archive/2010/04/16/9997517.aspx):
- MARS (Multiple Active Results Sets), which simplifies the application design process
- ALTER rename process for symmetry in renaming databases
- Application and Multi-server management for Data-tier Applications which further streamlines application design and enables deployments of database applications directly from SQL Server 2008 R2 and Visual Studio 2010 to SQL Azure for database deployment flexibility
Also you can take advantage of the new 50GB Databases en SQL Azure, you can become an early adopter of this new feature by sending an email to EngageSA@microsoft.com then you must fill out a survey and nominate your application.

Ahora SQL Azure implementa el Open Data Protocol, el Open Data Protocol (OData) es un estándar emergente para consultar y actualizar datos a través de la web. El OData es un protocolo basado en REST que se enfoca en maximizar la interoperabilidad entre servicios de datos y clientes. Dentro de estos clientes se pueden citar varias plataformas tales como ASP.NET, PHP, y Java, así como Microsoft Excel y aplicaciones móbiles. Más información puede encontrarse en www.odata.org
Si desea probar esta nueva característica se puede inscribir en https://www.sqlazurelabs.com
También en este blog http://oakleafblog.blogspot.com/2010/03/odataorgs-sql-azure-northwind-sample.html puede ver un ejemplo de utilizar ODATA con SQL Azure.

SQL Azure now implements the Open Data Protocol, the Open Data Protocol (OData) is an emerging standard for querying and updating data over the Web. OData is a REST-based protocol whose core focus is to maximize the interoperability between data services and clients that wish to access that data. It is thus being used to expose data from a variety of sources, from relational databases and file systems to content management systems and traditional websites. In addition, clients across many platforms, ranging from ASP.NET, PHP, and Java websites to Microsoft Excel and applications on mobile devices, are finding it easy to access those vast data stores through OData as well. Full information about OData can be found on its dedicated website. www.odata.org
You can subscribe to be an early tester of SQL Azure Open Data Protocol here https://www.sqlazurelabs.com
You can also read a full sample here http://oakleafblog.blogspot.com/2010/03/odataorgs-sql-azure-northwind-sample.html

If you are configuring a SQL Server to be used as an Session State for ASP.NET you need to configure the proper security to allow the application pool to access the SQL Server, you can use the following script to configure the security, remember to configure the proper identity (the one that is configured in the application pool)
use ASPState
go
grant EXECUTE on GetHashCode to [ApplicationPoolIdentity]
grant EXECUTE on GetMajorVersion to [ApplicationPoolIdentity]
grant EXECUTE on TempGetAppID to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItem to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItem2 to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItem3 to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItemExclusive to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItemExclusive2 to [ApplicationPoolIdentity]
grant EXECUTE on TempGetStateItemExclusive3 to [ApplicationPoolIdentity]
grant EXECUTE on TempGetVersion to [ApplicationPoolIdentity]
grant EXECUTE on TempInsertStateItemLong to [ApplicationPoolIdentity]
grant EXECUTE on TempInsertStateItemShort to [ApplicationPoolIdentity]
grant EXECUTE on TempInsertUninitializedItem to [ApplicationPoolIdentity]
grant EXECUTE on TempReleaseStateItemExclusive to [ApplicationPoolIdentity]
grant EXECUTE on TempRemoveStateItem to [ApplicationPoolIdentity]
grant EXECUTE on TempResetTimeout to [ApplicationPoolIdentity]
grant EXECUTE on TempUpdateStateItemLong to [ApplicationPoolIdentity]
grant EXECUTE on TempUpdateStateItemLongNullShort to [ApplicationPoolIdentity]
grant EXECUTE on TempUpdateStateItemShort to [ApplicationPoolIdentity]
grant EXECUTE on TempUpdateStateItemShortNullLong to [ApplicationPoolIdentity]
go
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" stateNetworkTimeout="10" sqlConnectionString="data source=127.0.0.1;Integrated Security=SSPI" sqlCommandTimeout="30" customProvider="" cookieless="UseCookies" cookieName="ASP.NET_SessionId" timeout="20" allowCustomSqlDatabase="false" regenerateExpiredSessionId="true" partitionResolverType="" useHostingIdentity="true" > <providers> <clear /> </providers> </sessionState>

Si ha configurado SQL Server como repositorio para las sesiones de ASP.NET puede que se le despliegue este error Unable to use SQL Server because ASP.NET version 2.0 Session State is not installed on the SQL server, esto se debe a que la cuenta con la cual está ejecutando el Application Pool del sitio en ASP.NET no tiene derechos sobre la base de datos en SQL Server, para configurarlo ejecute las siguientes instrucciones, recuerde cambiar la identidad del usuario por el usuario que tiene configurado en su IIS.
use ASPState

Si desea sincronizar su base de datos de SQL Server local con una base de datos en la nube de SQL Azure, puede empezar utilizando el SQL Data Sync, el cual le permite implementar una sincronización de datos bidreccional. Primero baje e instale el Microsoft Synch Framework 2.0 Software Development Kit (SDK) desde esta dirección
http://www.microsoft.com/downloads/details.aspx?FamilyID=89adbb1e-53ff-41b5-ba17-8e43a2e66254&displaylang=en
Después hay que bajar e instalar el SQL Data Sync CTP desde http://www.microsoft.com/downloads/details.aspx?FamilyID=bce4ad61-5b76-4101-8311-e928e7250b9a&displaylang=en
Una vez que haya instalado estos utilitarios podrá ejecutar el SQL Data Sync Wizard tal y como se muestra a continuación:
1. Primero necesita la dirección y contraseña de su servidor en SQL Azure, también necesita especificar el nombre de la base de datos en la cual usted desea replicar los datos, en este caso es AdventureWorks que está creada en SQL Azure. Si necesita información sobre el nombre del servidor puede acceder el portal de administración de Azure en esta dirección http://www.microsoft.com/windowsazure/sqlazure/ recuerde que debe configurar el firewall en el portal de SQL Azure para permitir el tráfico desde su servidor local hacia la nube.
2. Ahora debe especificar la información de la base de datos local
3. En el siguiente paso se debe especificar las tablas que van sincronizarse, además debe establecer la forma en que se van a administrar los conflictos.
4. El siguiente paso es especificar el orden en que se replican las tablas y finalmente se muestra la pantalla resumen:
5. Ahora puede dar click en Process para ejecutar la sincronización.

If you want to syncronize your local SQL Server Database with a Database in the SQL Azure Cloud, you can start using the SQL Data Sync that allows you to implement bi-directional data synchronization. First you need to download the Microsoft Synch Framework 2.0 Software Development Kit (SDK) from this address
http://www.microsoft.com/downloads/details.aspx?FamilyID=89adbb1e-53ff-41b5-ba17-8e43a2e66254&displaylang=en
Then you need to download the actual SQL Data Sync CTP from http://www.microsoft.com/downloads/details.aspx?FamilyID=bce4ad61-5b76-4101-8311-e928e7250b9a&displaylang=en
One you have installed both applications you will be able to run the SQL Data Sync Wizard as shown in the following steps:
1. First you need your SQL Azure server Address and Password, also you need to specify the name of the database that you want to replicate the data to, in this case is AdventureWorks that resides in SQL Azure. If you need you SQL Azure information you can access your account in the SQL Azure Portal in this address http://www.microsoft.com/windowsazure/sqlazure/ remenber that you need to configure the firewall in the SQL Azure Portal Page to allow the traffic beetween you local server and the cloud.
2. Next you need to specify you local database information
3. In the next step you will need to specify which tables will be syncronized, review the Conflict Resolution Policy, this allows you to specify how the the conflicts will be handled.
4. After that you can specify the order of the tables, and in the final step the summary will be shown:
5. Now you can click on Process to run the syncronization.

Con la introducción de SQL Server 2008 R2 Microsoft agregó la posibilidad de crear imágenes con Sysprep que incluyan una instalación de SQL Server 2008 R2, de esta forma ahora puede tener una imágen de estación de trabajo o servidor que ya posea SQL Server instalado. Para crear la imagen debe copiar los archivos de instalación al disco local de la máquina y cuando ejecute el instalador verá una nueva opción, tal y como se muestra a continuación:
Ahora continúe con el asistente de instalación y después ejecute la herramienta sysprep. Cuando ya se haya realizado la clonación del servidor o máquinas y ejecutado el Sysprep Mini Setup, usted verá una nueva opción para finalizar la instalación de este nuevo SQL clonado:
Existen algunas limitaciones, tal y como lo anota peteras (http://blogs.msdn.com/petersad/archive/2009/12/17/sql-server-2008-r2-sysprep-step-by-step.aspx) :
- Solo la base de datos y reporting services soportan sysprep
- No se puede utilizar en escenarios que incluyan cluster
- No hay soporte para IA64 o WOW64
- Los discos de instalación deben estar disponibles cuando se prepara y termina de configurar la imagen. Si va a instalar SQL Express debe extraer los archivos de instalación al disco local
Más información la pueden encontrar en http://msdn.microsoft.com/en-us/library/ee210754(SQL.105).aspx

Starting with SQL Server 2008 R2 Microsoft has added the SysPrep feature to the SQL Server setup, in this way you can now have a server or workstation image with SQL already installed, to create the image you must copy the setup files into the local disk, then when you run the setup you will see a new option among the already known ones:
What you need to do now is follow the setup wizard and at the end execute the sysprep utility. After you have cloned you machine and ran the sysprep mini setup you will see an option to finish the SQL Server configuration, as shown in the following image:
There are some limitations as peteras pointed (http://blogs.msdn.com/petersad/archive/2009/12/17/sql-server-2008-r2-sysprep-step-by-step.aspx) out on his blog:
- Only the database engine and reporting services supports Sysprep
- Cannot be used for clustering scenarios
- Not supported on IA64 system or supported in WOW64
- The installation media need to be available when preparing an image and configuring the image. When Sysprepping a SQL Server Express, you need to extract the files to the local machine before preparing the image.
More detailed step can be found here http://msdn.microsoft.com/en-us/library/ee210754(SQL.105).aspx

El 10 de abril realizamos el Evento Cloud Computing y Aplicaciones, en esta charla se trataron temas sobre SQL Server Azure y Windows Azure, la presentación la puede descargar desde la siguiente dirección http://comunidadwindows.org/files/folders/20100410/default.aspx
If you have two servers one running SQL Server Agent (SERVER A) and the other Integration Services (SERVER B) and you want to be able to run the SSIS packages on SERVER B from the Agent on SERVER A, you need to properly configure the firewall on SERVER B, if you don’t do it, you will run into the following error:
Error Could not load package "XXXXX" because of error 0xC00160AA. Description: Connect to SSIS Service on machine "XXXXX" failed: The RPC server is unavailableConnect to SSIS Service on machine “XXXXX" failed: The RPC server is unavailable
To configure the firewall follow these steps:
- Allow the C:\Program Files\Microsoft SQL Server\100\DTS\Binn\MsDtsSrvr.exe to go though the firewall, you can do it with an exeption in Windows 2003 or an Access Rule in Windows 2008.
- Allow the traffic for TCP port 135
**********************************************************************************
Si tienes que ejecutar paquetes que están en un servidor remoto tienes que asegurarte que el firewall del servidor remoto está correctamente configurado, para eso debes permitir trafico por el puerto TCP 135 y crear una excepción para el archivo C:\Program Files\Microsoft SQL Server\100\DTS\Binn\MsDtsSrvr.exe

When you are trying to create a new database for your Report Server through the Reporting Services Configuration Manager and the database server is not local but a remote server and in the remote server you have changed the default port and the SQL Browser is not running, you will run in the following error SocketException getaddrinfo no data of the requested type was found , and the configuration tool will show the following error in the Generating rights scripts section.
When you click on the Error link, you will saw the following detail:
System.Net.Sockets.SocketException: No such host is known
at System.Net.Dns.GetAddrInfo(String name)
at System.Net.Dns.InternalGetHostByName(String hostName, Boolean includeIPv6)
at System.Net.Dns.GetHostEntry(String hostNameOrAddress)
at ReportServicesConfigUI.RSDatabase.IsLocalDbServer(String dbServer)
at ReportServicesConfigUI.RSDatabase.GrantRSConnectionRights()
at ReportServicesConfigUI.RSDatabase.CreateNewDatabase()
This happens because the configuration tools is trying to resolve the server name you have specified, for example if your remote server is called DBServerA and you have created an alias whose name is DB you will run into this error. To solve it, you need to create an alias with the same name of the remote server and you have to specify the remote port, as shown in the following screenshot:
If you are running in a 64 bits machines you will also have to create the alias for the 32 bits clients, I had to create the alias twice for this in order to work.

If you are running tests on a SQL Server database using scripts, usually you may have to create a batch of TSQL and they must be executed in a certain order and in a certain time, to achive this you can use the WAITFOR DELAY statament, it allows your script to wait N seconds before being executed. In the following script we wait 30 seconds before executing the getdate command.
WAITFOR DELAY '00:00:30' ---- 30 Seconds Delay
SELECT GETDATE() CurrentTime
