Editor's Notes
- #11: Manage Development artifacts Copybooks, XML Schema(XSD), Web Service Definition Language(WSDL), COBOL CICS Web Service assistant parameters Pipeline name and Pipeline configuration Automate Build and validation CICS Web Service assistant parameters managed inside of changman Pipeline XML schema validation (COBOL XMLSS validate) Deploy zFS and Dataset promote/demote of required artifacts(wsbind, wsdl, xsd, etc) Install resource and perform Pipeline scan in our CICSplex
- #12: Leverage xml standards when possible ACORD, SWIFT, FIXML, etc Multiple approaches Top Down – Start with modeled schema and use generated copybooks internally in all programs(Rare) Meet in middle - Modeled interface with a program “wrapper” and controller to expose the business logic Controller layer helps combine multiple units of work Maximum reuse and no transformation on service bus Bottom up – Build WSDL from existing copybooks Simplest to do from a COBOL developer perspective Transformation on service bus to a public(modeled) interface is required CICS usually hosts our private service interface and the public accessed via our enterprise service bus. Using datapower for Validation, Authorization/Authentication, message transform Other best practices SSL Deploy/Backout –automatically perform the pipeline scan Have the ability to manage both WSDL and XSD in source code management tool or WSRR on day 1 Don’t waste time with a top down approach for existing business process Review/Document zfs backup and recovery process Validate new and changed pipeline definitions to ensure well formed COBOL XMLSS Ability to manage multiple pipelines in deploy process Developer training – XML, XSD, SOAP, WSDL, Soap UI Naming conventions – pipeline, zFS directories, services, programs, etc
- #13: Use RDz graphical wizards to build wsbind instead of the batch assistants Enhance Changeman or use RTC Enhance existing Changeman process to use JSON assistants for JSON Web Services Websphere Service Repository and Registry(WSRR) integration Worklight
- #14: Mix of stand alone and MRO prior to the CICSplex IA plugin makes it easy to navigate CICS resource relationships
- #15: Many acquisitions over the years resulted inconsistent process and development tooling(you name it we had it). We needed to simplify and standardize on a single set of development tools(multi year effort). Using CICS Explorer and PD Tools plugins inside RDz Develop in RDz and Deploy to our z LPARs or to RDT RDT contains bare essentials for development and testing
