THE IMPORTANCE OF SYSTEMS MANAGEMENT FOR A PARALLEL SYSPLEX

ISM S/390(R) Parallel Sysplex(TM), a multisystem parallel processing e nvironment, provides benefits in terms of reliability, availability, a nd the total cost of computing. These benefits, however, bring about a systems management challenge because of the increased number of addre ss spaces that need to be managed. This paper describes how CICSPlex(R ) System Manager (SM) for MVS/ESA(TM) provides simplified systems mana gement of multiple CICS(R) regions within a sysplex environment. CICSP lex SM provides workload-sensitive balancing of CICS transactions, a s ingle-system image for CICS operations and monitoring, and general-pur pose thresholds for resource conditions within CICS. It also describes how CICSPlex SM is integrated with the MVS workload manager, the MVS automatic restart manager, and automation products such as NetView(R) and the NetView resource object data model (RODM).
