Increasing challenges have put an even greater demand on enterprises around the world. These challenges include requirements on business compliance, governance with financial transparency, information privacy, and process control. However, businesses continuously look for new opportunities to satisfy new consumer demands by reacting swiftly and effectively to maximize their full potential.

IBM® System z® is a premier platform, with IBM CICS® Transaction Server for z/OS® running a huge number of critical business applications. Enterprises look to these business applications to get possible solutions for their challenges. CICS Transaction Server for z/OS V4.1 provides the ability to participate in event processing by capturing application events, which provide insight into the processing carried out in the enterprise's applications. CICS Transaction Server for z/OS V4.2 extends beyond that, and provides the ability to capture and emit system events, which provide insight into the state of the enterprise's CICS system and its resources.

The events are defined without the need to make any application or system changes. They can also be emitted in a number of standard formats, and thus easily consumed in many ways, by a range of commercial software products. System events allow the business to gain insight into whether the systems are able to support and run the business workload required, and to respond immediately when problems occur. All of these new capabilities open a way to satisfy the challenges faced by enterprises and, at the same time, inspire the potential for event-driven enterprise business.

This paper can help you to understand what CICS system events are and how to use them.
