1. Zowe Overview - Automation, Testing, and Orchestration
Dan Kelosky
Open Mainframe Team
linkedin.com/in/dkelosky
Lucky enough to be part of
Open Mainframe in Broadcom is Zowe stuff

2. Agenda Me Zowe Modern tools - purpose, how, & why I use them
Answer questions
Demos
test
build & deploy CI
I’m first - my perspective
Presented this before, but it’s a little different
team mates do something else - theyd need to submit the session

3. Mainframe Tools SLIP GTF
HLASM (31|64, Problem|Supervisor, System key[0-7], SRB|TCB)
Conditional Assembly
Metal C
Endevor
IPCS
ISPF
Console commands
IEASYSxx, PROGxx, etc
XDC
RDz
Millennial but now 10 years of working experience
First 5 years
Assembler and metal C developer - IDMS, Common Services NetMaster
Math major barely a computer science major - I don’t know source control - not interested in modern

4. Distributed Tools Android Cloud dev (firebase) apps & serverless
Web development (JQuery, Angular, Node.js, ...)
Scripting (Perl, Python, Ruby, JavaScript, …)
Editor extension (Brackets, Atom, VS Code, ...)
CI (Travis, Circle, Azure pipelines, Jenkins, TeamCity, Drone, …)
SHARE 2014 Pitt
Continued to be assembler and metal C developer - IDMS, Common Services NetMaster
As a hobby I started many side projects - not just reading about them but building them
Left the company and mainframe autonomous rail system for university of west virginia
but I missed mainframe - so when called back, I jumped at it - Continue assembler and metal C developer

5. Personal Tools diaper bag and all the stuff that comes with it snacks
dinosaurs

6. Zowe mainframe tools, distributed tools, personal tools
zowe a way to help bridge the tools
wierd picture

7. Zowe ML UI CLI APIs Explain REST in API like a browser
3 components of API ML
UI explorer - admin operations
CLI - focus b/c Im original developer of the CLI
zowe isn’t the only way to work with modern tooling

8. API https://phpenthusiast.com/blog/what-is-rest-api

9. API ML - Catalog

10. https://github.com/Netflix/eureka
API ML - Discovery

11. https://github.com/Netflix/zuul
API ML - Gateway
(unofficial)

12. UI & CLI

13. Modern Tooling - Overlap
git
Node.js
perl
python
explain each
Can use these on platform and it makes sense to do so
In other cases - perhaps its a lighter lift to install these in typical environments from the normal location - you can’t get node.js from their website
have fun installing

14. Modern Tooling - Parallels
Symbolic substitution - &SYSNAME.
Mustache, handlebars - {{ }}
JCL assembler service to perform symbolic substitution
Although its interesting that i can do both - it might be helpful in complex projects to be consistent
searching and diff utilities (super c) - regular expression over z/os wild cards

15. Modern Tooling - Integrations
RDz / Eclipse plugins
Jenkins plugins
CI tools
Can become outdated
Quirks - developers can tell
Can’t keep up - always will be a subset

16. Modern Tooling - z/OS Limitations
assembler highlighting
i wrote a version of this like a year ago and published it and it’s been enhanced in open source

17. Development is Complicated
Hybrid development - TypeScript (Node.js), Spring (Java), C++, Metal C, assembler, makefile, JCL
source controlled via git/GitHub
delivered through Endevor
Team members use different editors, diff tools, git clients
CLI, scripts, and task runner are common pieces
Consistency helps

18. Scripting Python Ruby Perl JavaScript / TypeScript
Bash / Shell scripts
Windows Batch
REXX
CLIST
Groovy Go
...
i’ll show the example in a moment
we tend to stick to JavaScript - it’s the most popular on GitHub and has been since 2014
Typescript appears to upwards - i think #7 in 2018
bring idea to life
we can script in them, the cli is developed in them, web is developed in them - maybe our services will be node.js someday and

19. Scripting Examples

20. Task Runners / Encapsulation Tools
npm / yarn
gradle
grunt
gulp
make
...
integrate with editors - show intellij and vs code and others for free
abstract operations - describe what you want to do, and it takes care of much details
we’ve tended to stick with npm & yarn is mostly compatible

21. Task Runners / Encapsulation Tools Examples
integrate with editors - show intellij and vs code and others for free
→ allocation example
Show running through CLI and through clicking
Automation tools understand these, show npm
show a command
show allocate
show upload
show build
show powermode & highlighting capabilities --- expose limitations of ISPF and benefits of open source

22. Testing Frameworks JUnit Jest PyUnit RSpec Mocha.js
perform an operation and programmatically determine whether the operation was as I intended
test a function adds numbers
test a function captures error if i add to strings

23. Testing Frameworks Examples
npm run test
gradle test
… etc
show code and run a test

24. Source Control git mercurial svn ChangeMan ISPW Endevor GitHub
Bitbucket
GitLab
...
i have remote interactions
I have higher level functionality in some scripting language (probably)
now start source control (see why in a moment)
Hosted / on prem repo
endevor, changeman, ispw

25. Source Control Examples
integrate with CI tools
issue tracking
release management
code review
work Jira, VersionOne, Waffle, Trello, Ration things
show GitHub UI

26. CI/CD Jenkins Drone Concourse TeamCity Travis CI CircleCI Drone Cloud
...
on prem / hosted
bias towards free / open source
urban code
XLR

27. CI/CD Examples mostly focus on CI - continuous integration
examples of deployment
show UI

28. CI/CD Tooling TSLint Codecov SonarQube JCLCheck TYPERUN=SCAN ...
A reason for why the CLI was developed

29. CI Tooling Examples
JCLCheck
Show lint operations

30. Demo 0 API ML Desktop UI Commands VS Code
talked about CLIs, task runners, and scripts
npm is a command line tool
im using the same tools
changed for demo - but we’re using this for a real project

31. Demo 1 - Testing npm run genjcl npm run allocate npm run upload
npm run jcl
npm run test

32. Demo 2 - CI
Drone
Commands
Task Runner
Test Automation
Power mode
