Action – Embrace DevOps Inaction – 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

An Integrated Development Environment for z Systems

10

Rational Developer for System z

A modern IDE for productive development of cross-platform applications written in COBOL, PL/I, ASM, Java, EGL or C/C++ in System z CICS, IMS, DB2, Batch applications

Access to typical System z sub-system functionality in z/OS, CICS, IMS, DB2, WAS

Integrated Debugger and integration with Debug tool

Integration with Fault Analyzer for Dump Analysis

Integration with File Manager for file and test data handling

Integration with Asset Analyzer for Application Understanding and Impact Analysis

Integration with Team Concert for Lifecycle and Source Management

Integration with RD&T for flexible access to System z environment

ISPF-based development

● Multiple screens/sessions and multiple disparate tools

● 20 x 80 characters of content

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

Access Jobs

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

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.

Key points for Demo 1:

• Navigation to z/OS resources is simple and consistent.

• Invocation of File Manager functions is consistent and intuitive.

• Manipulation of data using File Manager editor is consistent

regardless of underlying data stores.

• Copying of data from a resource to another is simple. For example,

copying of test data is made very simple using File Manager.

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.

37

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.
