  2. 2. © 2016 IBM Corporation2 Agenda  Mainframe software delivery pressures  What is RD&T?  Roger’s Communications’ use of RD&T  What’s new in RD&T 9.5  Deploying RD&T via IBM Cloud Managed DevOps
  3. 3. © 2016 IBM Corporation3 Business constraints with mainframe environments today Do any of these pressures sound familiar? All teams share one dev/test LPAR. If someone gets behind, or causes an error in the environment, everyone is impacted. Systems programmers need a safe place to practice, test new software updates, recreate issues etc… Agile has meant a threefold increase in compilations testing. We have better productivity but development chargebacks also increased dramatically. A new version of the COBOL compiler has been released and an impact assessment is required before switching to the new release When production systems do quarterly accounting, development is squeezed and work slows. Sometimes necessary testing does not happen and quality suffers. Agile software delivery requires prototyping and tinkering. Developers and testers can’t touch mainframe configurations, and sometimes it takes weeks to have operations make an experimental change.
  4. 4. © 2016 IBM Corporation4 Typical z Systems Testing Architecture Organized by project team, vertically scaled, sharing resources, limited automation z/OS Dev/Test LPARProject Team [April Maintain] Project Team [Prototype SOA] Project Team [June New Func] Project Team [Dec Sys Upgrade] Data App App App 1.Shared resources combined with overlapping schedules can elicit conflicts, impede innovation and slow code delivery 2.Coordination of environmental changes and releases cause bottlenecks, delays and additional overhead 3.Shared test data is difficult to manage and can lead to over testing or incorrect test results

The Program may not be used to run production workloads of any kind, nor more robust development workloads including without limitation production module builds, pre-production testing, stress testing, or performance testing. “RD&T improved our development and testing timeline and provided stability and quality” Developer, Large Enterprise Computer Services Company NEW NEW NEW
  9. 9. © 2016 IBM Corporation9 Typical RD&T use cases  Modernization- drive newer technologies and levels of software to production more quickly – Prototyping – z/OS software betas or upgrades – Development  Employee Education in an indestructible, approachable environment  Distributing development and test activities for higher availability, quality, and productivity. Benefits: – Increased availability of mainframe dev/test environment – Reduces issues with shared data – No waiting for sys admins to make changes on the mainframe  Enabling new software delivery methodologies such as Continuous Integration  Enabling development and test for geographically dispersed and outsourced teams

  23. 23. 23 Build simple and reliable application deployment procedures Web-Services Application Deployment RD&T Webinar RD&T • Challenge o Web-services java code is packaged in a WAR file o Multiple deployment options: dropins, Liberty application , CICS bundle. Pros and cons for each option o z/OS java deployment new at Rogers Communication, existing tools only partly applicable • RD&T Benefits and Solution o Experiment with different deployment options o Final decision – dropins for developers, deploy as a Liberty “application” for QA and PROD o Procedure tested till perfect o Other lessons learned o Keep in mind that the process will be automated. Scripts can easily manipulate files as a whole (copy, rename) but are less suitable to modify a configuration file (e.g. change an XML attribute) o Instrument the application to report what version of the application is running and what is the build number/date-time o In a clustered environment, provide an endpoint on each node for support and monitoring purposes
  24. 24. 24 • Disconnect development from the z/OS software upgrade cycle o Early access to new features o Reduce distraction of sys prog staff o No differences when code moved to z/OS LPAR • Bypass normal security constraints o Loose security for CICS, RACF, USS etc o Config changes by dev team with sys prog assistance o Test ID for RACF crypto setup o Eliminate hand off delays, request/approval/configure/test repeat • Fail fast o Learn by trying - cycle time reduced o Liberty/CICS docs provide examples with slight differences – able to quickly try out config changes RD&T enabled agile design of complex solutions Conclusions RD&T Webinar
