  5. 5. © 2013 IBM CorporationIMS Connect Configuration• No changes are needed in the IMS Connect configurationmember HWSCFGxx of the IMS PROCLIB to support IMSCallout• XML transformations for SOAP Gateway messages– User Message Exit HWSSOAP1– Add the ADAPTER statement– Concatenate DSN for XML converters in STEPLIB of the startup JCL
  6. 6. © 2013 IBM CorporationIMS SOAP Gateway
  7. 7. © 2013 IBM CorporationIMS Enterprise Suite SOAP Gateway Overview• A Light-weight Web Service solution for IMS without the need of aJava EE server• Integrates IMS assets into the Service-Oriented Architecture (SOA)• Provides end-to-end interactions between IMS transactions and webservices clients in an On Demand environment• Enables IMS as Provider and Consumer of Web Services• Secure• Tooling support– Utilizes Rational Developer for System z tooling to create converters for transformingXML messages to IMS messages and vice versa– No need to change existing IMS application code (provider scenario)
  8. 8. © 2013 IBM Corporation• Eclipse-based application development tool for modernizing and developingSystem z applications– COBOL, PL/I, C, C++, HL Assembler, Java– Supports IMS, CICS, Batch, USS, etc..– Interactive access to z/OS system– Access PDS and run JCL from your workstation• Premier IBM Integrated Development Environment for development and test ofIMS applications– Drag-and-drop code snippet function for IMS DLI callsIMS application development and modernization: Rational Developerfor System z (RDz)• Also supports IMS SOA enablement– Enables CICS and IMS applications for WebServices and SOA– Built-in wizard for SOAP Gateway and Web 2.0– Generate XML COBOL/PLI converters for XMLtransformation– Generate WSDL, correlator files for WebServices access
