Preparation:
Description:
This tutorial creates a service from a CICS COBOL account inquiry transaction (part of the CICS IVP Menu application), which accepts an account number and returns the customer information associated with the account number, as shown in Figure 1:
Phases 1 and 2 occur within the service flow project development environment. Phase 3 occurs within the runtime environment. This tutorial focuses only on the activities that occur in Phases 1 and 2 and does not discuss deployment, definition, or invocation of the code. For information on defining and invoking services in the supported runtime environments, consult the associated runtime documentation.
The service flow project tools can generate either COBOL source code for the CICS Service Flow Runtime or a macro for the Rational® Host Access Transformation Services (HATS) V6.0.3 or later (see Supported runtime environments for each project type).
This tutorial generates code for the CICS Service Flow Runtime environment.
The service flow project tools provide various methods to create and manage your resources. This tutorial uses the host editor to record a flow from the IVP Menu CICS application screens, which causes the service flow project tools to perform many of the necessary creation and management activities automatically.
