Rational Developer for System z

Developing service flow projects

The service flow project tools, which are a part of the Enterprise Service Tools component of IBM® Rational® Developer for System z®, allow you to develop a comprehensive service flow that invokes and processes data from multiple existing applications, including CICS® nonterminal applications, CICS terminal applications, and Web services.*

A service flow allows you to integrate calls to existing CICS applications with calls to new CICS applications or to Web services, without having to rewrite existing CICS applications.

To run a service flow you need the CICS Service Flow Feature (Service Flow Runtime) (see Supported runtime environments for each project type).

You can also generate a macro for the Rational Host Access Transformation Services (HATS) runtime from a service flow project (see Supported runtime environments for each project type).

You can invoke a service flow in the following ways:
