Delivering CICS Web Services for CA Gen Applications
The document discusses the need for CICS web services in CA Gen applications, emphasizing the advantages of exposing existing mainframe applications as modern web services without requiring extensive restructuring. It outlines the capabilities of Web Services Genius, a solution for creating and deploying SOAP and RESTful web services from CA Gen applications, which simplifies the process and reduces the need for new middleware. The presentation also highlights the ease of generating web services, migrating them between models, and the benefits of rapid delivery to enhance application performance and usability.

- 7. z/OS Mainframe CAB CAB CAB CICS Web (Pipeline) SOAP REST Cobol Wrapper “Exposed” CAB CAB Web Services GENius – Solution Architecture Generation •Cobol wrapper • Import/Export Copybooks • Compile&link Cobol Wrapper • Build REST Service: JSON Schema+ • Build SOAP Services: WSDL Developer workstation Define Web Services from any CAB/Pstep in the HE/CSE HE/CSE Distributed environment Application server WSDL JSON Schema
- 8. Configuring Your Site and Models A single windows client • Simple clear layout • Interacts with Encyclopedia •Enables all configuration • Where Web Services are defined Tree nodes are hierarchical • Root node for site-level config • Model for model-specific config Drag and drop to replicate • Configurations can be dragged from one model to another model. The tree view of all the models in the Encyclopedia shows each candidate Pstep and Action Block Object property information for the site, individual models and each web service Web Services interface definition area
- 9. Creating Web Services ..or selecting an existing Web Service.. … allows the Interface definition to be named and the URI to be specified so the service can be located Every part of the exposed Web service interface can be named in a way that makes sense for the Web Service consumer A context-click on the selected action block.. Web Service definitions • On CABs or Psteps • Multiple Web Services Configured as required •Named as needed • Data exposed as necessary • Hide or Fix any attribute. Each data item can be: - Omitted - Set with a Fixed value, or - Passed through (Variable)
- 10. Simple click-to-generate • Generate single or multiple WS’s • Creates Cobol and control files •Packaged as a discrete “Remote” Build the generated RMT on z/OS • Supplied batch job for Build, OR • Supplied ISPF panel Build deploys all artefacts • JSON/WSDL created • URI’s operational and active. Generating Web Services – CSE Context click, and.. generate Creates all the files ready for building on z/OS.. .. and a “Remote” containing all required artefacts ready for Build.
- 11. Build using supplied ISPF panel • Takes the generated Remote file • Builds all artefacts for use Deploys all artefacts for use •JSON and Bind files for RESTful APIs • WSDL for SOAP Web Services • Active on nominated URI’s Can be customised • Every site is different • Modular design for customisation • Talk to us about what is needed. Building Web Services – CSE Specify the location of the uploaded Remote file And see the build results for each Web Service
- 12. Generate & Install with ISPF panel • Operates on a single Web Service • Specify environmental options Generation creates all WS artefacts •Cobol wrappers and copybooks • WSBind, WSDL and JSON Schemas • Deployed to nominated libraries Can be customised • Every site is different • Modular design for customisation • Talk to us about what is needed. Generating Web Services – HE Standard build panel allows the Generate and/or Install of any defined Web Service … and your sites’ preferred environmental options ..and see the build results for the Web Service Generation & Install
- 13. Migrating Web Services Between Models Web Services can be dragged and dropped between models • Once defined, any Web Service can be replicated to another model with drag-n-drop •Simple method removes the risk of incorrectly re-defining Web Services manually The target model for the existing Web Service • Must already contain the same action block • The action block view structures should match • The ancestry for that action block must be in place • And the target model has been configured for Web Services Promotion of Web Services is simple • When the Web Service is ready to be migrated “up”, simply drag-n-drop • Once migrated, the Web Service only needs to be Generated and Built.
- 14. Key Benefits of Web Services GENius Publish CICS Web Services directly from CA Gen mainframe applications • New and unique capability to deploy SOAP or RESTful Web Services on Gen applications •Create Web Services from any Pstep or CAB without change to the Gen applications Web Services GENius simplifies your application delivery • No new layers of middleware or hardware – leverage what you’ve got • Exploits TCP/IP and IBM’s CICS Web Services infrastructure development • Insulates developers from underlying technologies to accelerate Web Service delivery No need for re-training development teams or new skill sets • Seamless integration with CA Gen and IBM technologies • Existing development teams can quickly deploy new Web Services.
