COBOL Scenarios

Scenario I: Calling an Existing COBOL Server

Start of instruction setTo call an existing COBOL server

  1. Use the IDL Extractor for COBOL to extract the Software AG IDL and, depending on the complexity, also a server mapping file. See When is a Server Mapping File Required? in the EntireX Workbench documentation.

  2. Build an EntireX RPC client using any EntireX wrapper. See EntireX Wrappers. For a quick test you can:

    • use the IDL Tester; see EntireX IDL Tester in the EntireX Workbench documentation

    • generate an XML mapping file (XMM) and use the XML Tester for verification; see EntireX XML Tester in the XML/SOAP Wrapper documentation

See Client and Server Examples for z/VSE Batch in the COBOL Wrapper documentation for COBOL RPC Server examples.

Scenario II: Writing a New COBOL Server

Start of instruction setTo write a new COBOL server

  1. Use the COBOL Wrapper to generate a COBOL server skeleton and, depending on the complexity, also a server mapping file. See When is a Server Mapping File Required? in the EntireX Workbench documentation. Write your COBOL server and proceed as described under Using the COBOL Wrapper for the Server Side.

  2. Build an EntireX RPC client using any EntireX wrapper. See EntireX Wrappers. For a quick test you can:

    • use the IDL Tester; see EntireX IDL Tester in the EntireX Workbench documentation

    • generate an XML mapping file (XMM) and use the XML Tester for verification; see EntireX XML Tester in the XML/SOAP Wrapper documentation

See Client and Server Examples for z/VSE Batch in the COBOL Wrapper documentation for COBOL RPC Server examples.
