Under z/OS, a COBOL server can be called in different environments:

	Extract the interface of the COBOL server program.
	Generate connection and adapter services in Integration Server.
	Execute the call from Integration Server to the COBOL server program.

Continue with the appropriate scenario:

• CICS - Choose your CICS calling convention:

  • DFHCOMMAREA (using RPC Server for CICS)

  • DFHCOMMAREA (using CICS Socket Listener)

  • DFHCOMMAREA (zero footprint using CICS ECI)

  • Large Buffer

  • Channel Container

• Batch

• IMS - Choose your IMS environment:

  • MPP - online transactions (zero footprint using IMS Connect)

  • BMP - batch processing (using RPC Server for IMS)
