Develop

Alan Andersson (COBOL Application Developer) and Jash Jayaraman (Java Application Developer) can check out code from the SCM system

and modify it.

Once happy, they commit the code back to the SCM system.

Pre-delivery builds help them both to know that their code will compile and they can test the results as they code.

Once they’ve committed, they can see the results of their changes in the resultant builds and automated tests, to fix problems quickly.


Build

Bobbie Beckett (Build Engineer) has written build automation, using the new CICS Build Toolkit, to build:

- CICS bundlesEvents, policies and other resourcesJava OSGi bundles and Liberty applications

- CICS cloud applications

Bobbie sets up CI servers to run the build after every code change, just like their native code.

The builds also run automated tests.


Release

Richard Renner (Release Engineer) has written release automation for the company’s CICS bundles and applications using the new JCL utility DFHDPLOY, which simplifies how he writes that automation.

He also works with his fellow release engineers across the company to use UrbanCode Deploy (with the new CICS plugin) to deploy CICS components in unison with other components.

New builds can now be quickly and automatically deployed to the right environments.

UrbanCode Deploy

COBOLA traditional CICS application in COBOL, using its existing tools and build infrastructure, forms part of a coordinated deployment with other artefacts using UrbanCode Deploy.

COBOL + PolicyA traditional CICS application in COBOL, managed by policies deployed in a CICS bundle, is deployed using UrbanCode Deploy.

Liberty Profile A Java EE application with a RESTful front-end is built automatically and deployed using z/OS automation.

Multi-version COBOLCICS application

A CICS cloud-style application is built automatically and deployed using z/OS automation without loss of service.

COBOL + OSGiAn application, mainly composed of COBOL but with modules that have been converted to OSGi, is deployed using UrbanCode Deploy.

Command-line interface to build CICS projectsScript alternative for “Export ... to z/OS UNIX File System”

One tool to build for all versions of CICS TS

Uses projects from CICS Explorer optionally shared through SCM

Installation on z/OS, Linux, Windows Transfer cicsbt_v5.3.0.0.zip from CICS beta site in binary

Unzip; jar -xf cicsbt_v5.3.0.0.zip

Make executable on z/OS and Linux; chmod a+x *.sh

Requires• Java 7 or above, for z/OS IBM 31-bit or 64-bit SDK

CICS Build Toolkit


CICS Build Toolkit examples

Build a CICS bundle

Bundle ID, bundle ID + version, several bundles, all bundles

cicsbt --input my/source/dir/*

--build MyBundleProject --output my/output/dir

Build a CICS bundle that references an OSGi Java project + Liberty apps

For OSGI can use a CICS version .target or your own

cicsbt --input my/source/dir/* --build OSGiBundleProject --target com.ibm.cics.explorer.sdk.runtime51.target --output my/output/dir

Build a CICS cloud application and binding

Application binding ID, binding ID + version, all applications and bindings

cicsbt --input my/source/dir/*

--build MyApplicationBinding

--output my/output/dir


CICS Build Toolkit as part of continuous integration

Build Engineer can write a build script to:

Check out resourcesBuild CICS applicationCopy to staging

Test, and run from continuous integration build server, such as Jenkins or RTC


DFHDPLOY batch utility

Automate deployment of bundles (and applications) through simple single commands…

“Take a bundle on disk, install it, and take it to the state I want.”... and the reverse as well.

Automation runs faster - takes advantage of new synchronous APIs where available.

Intelligent management of BAS and CSD definitionsIncluding support for shared CSDs


Example DFHDPLOY script


Example DFHDPLOY output


• Continuous Delivery– Integrate with build and test tools to automatically deploy, test and promote new builds

• Production Deployments – Orchestrate a complex production deployments of applications and configuration

• Self-Service – Grant teams rights to “push the go button” for different applications and environments

• Incremental Updates – Deploy only the changed components or missing incremental (patch) versions
