Leveraging CICS Events with an ESB

An IBM Redbooks publication


Abstract

There are many reasons to use an enterprise service bus (ESB) as the event bus:


  • Transformation: Function that transforms the incoming event by translating or splitting it
  • Enrichment: Function that enriches the content of events with reference data from multiple possible sources
  • Validation: Function to provide validation against required criteria
  • Pattern detection: Function that recognizes actual and retrospective patterns; a combination from possibly multiple events, characterizing a significant business situation
  • Filtering: Stateless function that filters events based on their content, that is, the information that is carried by the message generated when the event happened
  • Aggregation: Function that can group events as necessary
  • Routing: Function that routes events to the destination based on various possible routing patterns, such as pre-established itinerary, calendar-based, or subscription or “intelligent” routing decisions

In this IBM® Redbooks® publication, we show examples of using an ESB to transform and enrich an event received from Customer Information Control System (CICS®) Transaction Server. We also show an example of enriching an event.

This book is intended for anyone planning to use CICS events with an ESB.

This book contains four parts:
Part 1, "Introduction" on page 1 introduces event processing. We explain what it is and why you need it. We also review the CICS TS implementation of event processing. We discuss enterprise service bus technology and how to integrate event processing with an ESB.

Part 2, "Environment" on page 55 of the book focuses on our environment and the application we chose to use.

Part 3, "Scenarios" on page 89 describes our scenarios with three separate ESBs along with information about the IBM WebSphere® Business Events, IBM WebSphere Business Monitor, and IBM WebSphere Process Server for z/OS® setup details:
Scenario 1: IBM WebSphere Enterprise Service Bus for z/OS business scenario
Scenario 2: IBM WebSphere Message Broker for z/OS business scenario
Scenario 3: DataPower® business scenario
Scenario flow
WebSphere Business Events
WebSphere Business Monitor
WebSphere Process Server

Part 4 of this book describes best practices:
Governance
Security
