If you need to attract new developers, and want to keep your company’s name out of the headlines, then this session is for you. When your business depends on your mainframe apps working and performing well—all the time—you need to be alerted to issues as they occur and have the tools to help you find and fix the problems and test your solutions before disaster strikes (we’ve all been in those late night and weekend drills). You also need to continue supporting these applications for years to come, and that will require new talent. This session will introduce you to the development environments that college grads are already comfortable with, and help your applications become more resilient at the same time. We’ll walk you through the tools to help you accomplish all of this and demo some scenarios to show you how efficiently our tools can perform the tasks that slow you down.

Action – Embrace DevOpsInaction – Status Quo
•Status quo – don’t change
•FUD: “millennials can’t code COBOL”,
“manual processes exist for a reason”, “SoR
dev can’t be as nimble as dist’d”
•Slow – SoR dev the bottleneck
•High cost – “inhibitor to innovation”
•High risk – business becomes uncompetitive
•Change agent – accept the mission!
•New reality - make a radical shift with
DevOps…and lean, and MVPs, and…
•Fast - client feedback incorporated
•Low cost – incremental deliveries, new
client value
•Low risk – better quality, holistic dev /
delivery

The Benefits of a RDz's IDE
• Instead of maneuvering to access panels and working sequentially,
• in RDz the functionality you need is always in-focus – you work concurrently
Access Datasets
+ Dataset

Access Jobs
(Outlist facility)
Edit a program

13. What productivity gain can I expect from RDz?
• An IBM productivity study concluded that RDz significantly improves productivity
as compared to ISPF
• 100 common (daily) ISPF tasks used during maintenance and support
assignments
– ISPF workflow translated (click-for-click) to RDz development
– Project participants believed they were trying to find gaps between RDz and
ISPF functionality
• Mix of experienced (veteran) ISPF programmers and new-hire developers
Productivity increases translates to real dollar savings and improved
application delivery time

14. zUnit – Unit testing framework for z/OS
• Frameworks that assist developers in writing code
to perform repeatable, self-checking unit tests are
collectively known as xUnit.
• xUnit defines a set of concepts that together
provide a light-weight architecture for
implementing unit testing frameworks.
– JUnit, for example, is a very popular instance
of the xUnit architecture.
• zUnit is a xUnit instance for System z
• Goal is to encourage the continuous integration
and continuous testing methodology for System
z Application development and maintenance.

37. Key points for Demo 2:
• The problem is reported using a RTC work item.
• Fault Analyzer abend analysis made the problem analysis simple.
• Integration with File Manager made the manipulation of erroneous
data simple.
• The outcome from the problem analysis is reported in the same
work item.

38. Additional considerations for Demo 2:
• In the previous example, erroneous data is simply updated.
• What if coding change is required?
– Make changes using RDz.
– Interactive debugging, performance analysis, unit testing, code
coverage analysis…
– Manage change record using RTC’s work item.
• Keeping data for testing purposes?
– Keep a copy of erroneous data for further analysis.
– Keep a copy of erroneous data for regression testing.
– Protect sensitive information using File Manager’s data
scrambling.
