“Drinking our own champagne” is how we approach technology here at Serena. If we have a our own tool that supports part of the application development lifecycle we use it for our own development efforts. In fact the Serena development teams deploy the beta versions of our solutions straight into their production environments because they want exploit the cool-new-stuff just as much as you do!

When I sat down today to start writing about automated deployment in modern enterprises I thought I’d follow the Serena mantra and “drink our own champagne” too. So I

As the overall owner of the content for our next xChange global user conference, I always remember that the heart of xChange15 is the breakout session content but the soul of xChange is the array of fantastic customer presentations.

I am delighted to announce that, as of today, you can learn more about the xChange Call for Speakers on the xChange website and then submit your ideas for presentations Read More



System’s programmers on the mainframe have a pretty difficult time these days. More and more complexity, rampant growth of z/Linux, Websphere and RD&T boxes. Draconian constraints, compliance and governance mandates to be applied. All with fewer and fewer resources. It is a common problem.

Serena is here to help. Our ChangeMan SSM technology is designed to be the SysProg’s best friend and unswerving ally.

Sitting quietly in the background monitoring system datasets and members like the APF authorized libraries, the LINKLIST datasets, console commands and any

Business man runningThis is the first installment of an occasional series of posts in the run up to the launch of ChangeMan 8.1 later this year. As part of the routine pre-launch activities I’ll be chatting to the development team to learn about the cool features that have been added to this latest version.

ChangeMan ZMF is used by some of the largest mainframe development shops in the world. It is typical for these organizations to have hundreds of thousands of components managed and tens of thousands of components in motion. Keeping

Myth: Errors happen: It’s software

Errors do occur. They occur for a reason. Often those reasons are out of our control. Someone changes an IP Address of a server. Someone changes the password to the back office system. Someone changes the name of a shared .DLL.

Of course in a well-managed and carefully controlled environment those kinds of things shouldn’t happen without the proper authentication, notification and approval. And the infamous “someone” is a responsible professional who calculates the impact of their changes and collaborates with everyone to minimize that impact. In a perfect world.

In the real world change is constant and calculating the consequences of change

As the DevOps movement approaches its 5 year anniversary, the question remains: is the movement ready to cross the chasm into mainstream IT? 

Stories of unicorns abound, and if we believe the vendors and early adopter case studies for the enterprise, we would be feeling that we are on the other side of the chasm, ready to get inside the tornado, change the culture and

Myth: Each deployment needs me

Helicopters have been described as “10,000 parts flying together in close formation. It is the mechanic’s job to keep that formation as tight as possible.”

Modern software applications comprise of millions of parts when you consider the huge chunks of code we bind into our applications from the database, security, web server, communications, encryption and authentication vendors. Add to that the seemingly infinite numbers of dependencies on external web services and internal CRM and financial systems.

There are 100 million lines of code in the Ford Taurus

But, just like the helicopter’s mechanic, the
