Figure 5. OLTP Market Segmentation Model 1.6 Summary 12 CICS for AIX as the Transaction Server The big challenge that enterprises face in the area of OLTP is complexity. Good, comprehensive solutions are in great demand. In Part 2 of this book we describe the best solution available: IBM Transaction Server for AIX Version 4 and CICS for AIX.
Part 2. The Solution Today′s OLTP systems are so varied and complex that is beyond the scope of one software component or product to solve all of needs an enterprise′s requirements for implementing its business systems. The development of complete, robust, and managed systems can occur only by combining software components into packages. In Part 2 of this book we show how the IBM Transaction Server for AIX and CICS for AIX can be used as the foundation on which you can build your distributed enterprise business systems. Taking CICS for AIX as the core enabler of our OLTP system, we examine how other components in the IBM Transaction Server for AIX and other IBM Software Servers can be combined to provide a framework for highly interconnectable, robust, and reliable business systems. For each of these other components we examine the benefits they bring to the total environment and how they can be combined with CICS for AIX. We then discuss the planning issues associated with combining these components with CICS for AIX. We aim to show the high degree of flexibility that exists within a CICS for AIX based environment. Whether you want to access existing enterprise data or make the best use of existing Intel-based hardware, for example, CICS for AIX and other members of the CICS family provide the right facilities. © Copyright IBM Corp. 1996 13
