provide greater protection in the unlikely event that the entire 8-node RISC System/6000 SP system experiences an outage. Figure 48. DCE Servers Required by CICS for AIX 11.9 Summary 168 CICS for AIX as the Transaction Server CICS for AIX in conjunction with the IBM Software Servers have proven themselves capable of handling the most demanding business requirements of TDJ. They can deliver new technologies, such as client-server computing, distributed processing, object-orientation, and the Internet, all of which are constantly evolving in response to changing business needs. CICS for AIX not only capitalizes on evolving technologies but also enables TDJ to implement client-server solutions across multiple hardware platforms and operating systems. Just as importantly, CICS for AIX frees programmers and end users from the complexities of the underlying technologies and enables them to concentrate on developing and running the necessary business systems. With CICS for AIX, TDJ can make information and applications immediately available where they are most needed—on the desktop of the end user. The end user is not constrained to using only one particular make of PC or running a particular operating system in order to access a CICS for AIX region. The any CICS client to any CICS server strategy gives the staff of TDJ the opportunity to
exploit business-critical information directly from standard desktop packages, significantly increasing the value of both centralized and local information. CICS for AIX also protects TDJ′s past investments by extending their usefulness. Through a GUI, the presentation of existing applications has been modernized without having to rewrite the business application. Moreover, mission-critical CICS applications are easily ported to distributed platforms, leveraging the value of the enterprise network. In the security area, CICS for AIX complements industry-standard security managers with its own security features that coordinate different databases, protect against network failures, and ensure the integrity of business data and application software. TDJ divided its CICS installation on a business-unit basis, providing independent operation for one department while allowing controlled access to resources belonging to another. CICS for AIX has become the transaction server of choice for TDJ in the new world of distributed, open OLTP. With CICS for AIX, TDJ can deliver on its strategy of a distributed, open OLTP environment across its entire enterprise network. Chapter 11. TDJ Enterprise International Limited 169
