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 anyRead More
This 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. KeepingRead More
UPDATE: Patrick was unable to speak last week, so we rescheduled the webcast to this Thursday at Noon ET / 9 am PT. Please register here.
Patrick Debois coined the term “DevOps” as part of the first DevOpsDays nearly 5 years ago. Now DevOps is a major movement in the smallest start-ups and the largest enterprises.
I welcome you to join me Read More
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 changeRead More
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 andRead More
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, theRead More
“I don’t want to know why it happened: I just want you to fix it!” was what I was told early one morning by the Director of Sales. And she was right: getting the online store back online was the most important thing for the business. Blamestorming would come later.
There is a temptation at 3:00 am to just do whatever it takes to bring the system back on the air even if that means bypassing protocols and procedures designed to protect system integrity. Sales-and-Marketing and Audit-and-Compliance might not see eye-to-eye on this approach.
So why do emergency fixes have to be different? This myth is all about time. The time it takes to write the script.Read More

When we started this series we talked about how release engineers have difficulty in keeping up with the rate of change in their environment. Every day a new security patch or software update is applied that changes the known topology of one or more deployment targets.
This is why, some release engineers insist, they have to hand-craft the deployment scripts each and every time.
In an ideal world every target environment would be standardized. But we don’t live in an ideal world. Whether it is our own on-premise platforms, virtualized or cloud platforms we know that their configurations are in a state of constant evolution. This makes it hard for release engineersRead More
