xTEN have acquired Aireforge, the company that created Aireforge Studio. This application helps data professionals optimise, secure and maintain their SQL Server estates.
Aireforge was co-created by xTEN’s founder, so it made sense to bring these companies together. The application means that anyone can have access to over 30 years’ SQL server expertise, and helps the team here at xTEN deliver services even faster, adding value from day one for our customers.
Aireforge Studio is comprised of five modules to cover all aspects of a Data Professional’s role: Optimize, Compare, Estate, Check and Script. At xTEN, we use Aireforge Studio to uncover a wide range of issues when we are troubleshooting clients’ estates. This helps us get customers’ databases in a better state as fast as possible. We even use it to fix, manage and tune databases.
This acquisition means our customers will enjoy an even better service from xTEN. We’ll be able to use Aireforge as we are currently, but we’ll also be able to build our team’s knowledge into the application. We’ll have direct access to the Aireforge team so we can make sure the app is optimised for our customers. We’ll also show clients how to use the tool within their own teams, so they can start bringing advanced troubleshooting in-house. This means they’ll get more value for money from their xTEN relationship and grow knowledge within their own organisation.
xTEN’s customers are already benefiting from Aireforge Studio so we’re excited to open these opportunities to even more clients. One example is intuitive, a leading travel technology supplier, who used Aireforge Studio to speed up their services, improve security and get insight into their databases. This has resulted in happier customers and a more resilient service.
If you’d like to start getting more value from your SQL Server estate today, have a look at Aireforge Studio or get in touch with xTEN to find out more about our services.

I normally blog about SQL Server, but I thought I’d share my experience of using SQL Server from MuleESB. If you haven’t used Mule before, it’s an open source ESB, which also has a paid for Enterprise version. I’ve been using it for almost four years now and have been really impressed with how quickly we can create quite complex applications. It’s very fast, easy to use and free if you use the community version; I also have some experience with Java which helps. I tend to use Mule for applications that process web requests or when integrating with existing systems and SQL Server Integration Services (SSIS) for moving data around.
I’ve been working on a MuleESB program which needs to log millions of requests a day, and with the recent advancements in SQL Server, it’s now the obvious choice for storing almost any type of data. You can also run SQL Server 2017 on Linux, which will please a lot of Mule users.
Mule previously had a MSSQL connector but that has been deprecated and replaced with the Generic Database Connector, which works with most JDBC drivers. To get started, we’ll need to download the latest driver from Microsoft and add it to our project. We can then configure the database using a standard connection string.
Download and add the JDBC driver
At the time of writing, the latest is JDBC 6.4; which you’ll need if you want to use SQL Server 2017 but my screenshots all reference JDBC 6.2.
Add to your Mule Project using Add External JARs…. and selecting either mssql-jdbc-6.2.2.jre7.jar or mssql-jdbc-6.2.2.jre8.jar; depending on your JRE.
Note: You’ll need JDBC 6.4 if you want a driver for JRE 9; you’ll also need Mule 4 as 3.9 doesn’t support Java 9.
Configuring the Database Connector
The database connector is surprisingly easy to configure. We simply add a standard connection string and reference the JDBC driver, which is the same regardless of which JDBC driver you use. Aireforge have created an online connection string builder which you may find useful here.
The above is fine for testing but I would suggest that you use parameters that are stored in a central configuration file to make your life easier. This will enable you to automatically set the environment settings using a local config file or manually change between Dev and Production by commenting each section out. I would also advocate using an application name, as this will help you or the database team to identify your application; rather than it simply showing as a JDBC program.
By default, the maximum database connections is 5, unlike .NET where it’s 100. If you think you’ll need more, then make sure you set it higher.
If you’ll be using the connection frequently; I would strongly recommend using a minimum connection pool size to lower the overhead on both Mule and SQL Server.
If you’re using the standard port, then you don’t need to specify it but it doesn’t hurt and future proofs your application.
Only bother with a re-connection strategy if you really need to the data. If it’s just logging, then consider throwing it away rather than overloading a server which may already be suffering from being overloaded.
If you’re load balancing the connections, I would also suggest setting the Load Balance Timeout, otherwise the connections will be sticky and won’t automatically balance after a server restart etc.
Again, I would set an an application name to help when diagnosing issues.
Consider enabling delayed durability when saving logging data as it will reduce the time in SQL Server and free up database connections quicker. I would also specify for the specific stored procedure in use rather than forcing it for the entire database. With Delayed Durability comes the possibility of data loss, so make sure you understand the risks.
Consider using memory optimized tables for very busy applications, then process the data using a separate process. This could be called from Mule or via the SQL Server Agent. Again, if the data isn’t important, I would opt for a SCHEMA_ONLY table; which is faster but you’ll lose the data should SQL Server restart. If this isn’t an option, you can use the default of SCHEMA_AND_DATA which will commit the data to disk.
Use a stored procedure or parameterised queries when communicating with SQL Server as this will enable SQL Server to reuse execution plans.
I’ve created a HTTP service listening on 8081 that will then connect to the database, retrieve the server and service name, then return it as JSON.
Here’s the example results in JSON.
Microsoft have made the cheaper (or free) versions of SQL Server very powerful by allowing us to use features which were previously enterprise only. For me, it does everything I need from a database. In-memory tables that can handles thousands of updates a second, to large clustered columnstore tables that can handle real-time analytical queries that drive dashboards.
It would be nice to see the JTDS driver get more attention, as it’s much faster than ODBC but at the time of writing, doesn’t work with the latest versions of SQL Server and doesn’t have much documentation / support. Maybe Microsoft could release and maintain JTDS driver in parallel to JDBC?
Utilizing the cache scope could also prove quite powerful as it will reduce the resource requirements of SQL Server, whilst improving the performance of your Mule application. I’ll try to blog on this soon but feel free to pester me if I haven’t.

Audley Travel is a Tour Operator providing high quality, tailor-made holidays. As the company was expanding quickly with multiple offices around the world, their aim was to improve resilience and improve their procedures in the event of unexpected downtime.
xTEN worked closely with Audley’s development and operations teams to design a solution that was best for them. Each office was given a local resilient cluster which can operate offline for days. This required some creative application changes and specialist knowledge of SQL Server. As well as this, we performed a SQL Server upgrade to utilise newer features and ensure version support.
The result: better protection against downtime. Thanks to the design, if one of Audley’s many office locations found their systems isolated, they could continue to work. This reduced the financial impact of time offline.
