Introduction to CICS Runtime

Introduction to the CICS Runtime Environment

Purpose

This guide provides explanations and instructions for configuring and using Oracle Tuxedo Application Runtime for CICS (CICS Runtime) when developing and running On Line Transaction Processing (OLTP) applications on a UNIX/Linux platform.

This guide describes the steps required to implement and perform COBOL CICS transactions, whether they are migrated from z/OS CICS or newly written for UNIX applications.

To illustrate this purpose, the User Guide provides a detailed description of the deployment and administration of the Simple Application in a UNIX environment.

This guide helps you to:

•	Configure CICS Runtime software.

•	Declare components to CICS Runtime.

•	Run a CICS Application.

How This Book Is Organized

This guide is divided into seven main chapters:

•	“Overview of the CICS Runtime” on page 2‑1: introduces the general principles of the CICS Runtime.

•	“Initial Configuration of the CICS Runtime” on page 3‑1: describes how to set parameters to make CICS Runtime operational before implementing CICS applications.

•	“Implementing CICS Applications” on page 4‑1: details how to configure the CICS Runtime to use CICS applications including examples moving from simple to more-and-more complex cases.

Additionally,

•	“Reference” on page 5‑1: contains information describing the .desc files used by the different CICS Runtime servers.

•	“Oracle Tuxedo Application Runtime for CICS CSD Converter” on page 6‑1: specifies how to set the target CSD file in argument, and the translated resource configuration files resides in current directory by default.

•	“ECI Client Support” on page 7‑1: elaborates ECI emulator that supports customers to keep using existed program without code change when migrating mainframe applications from IBM z/OS to an open systems application grid running Oracle Tuxedo.
