CICS

This comprehensive guide details the factors that drive CICS performance and helps readers develop comprehensive performance plans. Tackling a large number of vital CICS-related topics, it provides a single point of reference for designing and planning CICS performance through integration of software engineering, queueing theory, and workload capacity principles. Increasing its utility for all those planning CICS performance, the book describes the major structural features of CICS/VS, CICS/MVS, and CICS/ESA, along with performance-related differences. It also provides a simple methodology for quantifying performance-related factors and details capacity planning techniques, including methods of analyzing CICS workloads, forecasting growth, and estimating queueing delays and response time.
