Programming Models

A programming model defines the method(s) used to access and integrate server applications with host applications. A programming model is a combination of:

  • The communication protocol that is used to exchange data with the remote application program.

  • The target host environment used to host the server application program.

  • The interaction semantics defined by the application to control connect, data exchange, and disconnect sequences.

    Transaction Integrator supports a set of predefined programming models for Windows-initiated processing and for host-initiated processing. The following table summarizes the 11 available WIP programming models depending on the protocol and the target environment.

Protocol Target/Host Environment Host Integration Server Programming Model Host Integration Server COMTI name
TCP/IP CICS TCP Transaction Request Message (TRM) Link MS Link
TCP/IP CICS TCP Enhanced Listener Message (ELM) Link n/a
TCP/IP CICS TCP Transaction Request Message (TRM) User Data Concurrent Server
TCP/IP CICS TCP Enhanced Listener Message (ELM) User Data n/a
TCP/IP IMS IMS Connect IMS Open Transaction Management Architecture (OTMA) Connect
TCP/IP IMS IMS Implicit Implicit

LU6.2 IMS IMS LU6.2 User Data IMS using LU6.2

The following table summarizes the five available HIP programming models depending on the protocol and the target environment.
