Administrator Getting the most from your systems Raising the Bar IBM zAware extends z/OS resilience to another level By Geoffrey E. Miller I ndustrywide, z/OS* is known for delivering high qualities of service, including robust reliability, availability and serviceability (RAS). But the z/OS development team doesn’t rest on its laurels—it continues to innovate. measured in years. The mainframe has earned the trust of businesses for its resilient characteristics. However, expectations and demands for availability are ever-increasing, while tolerance for application outages, whether planned or unplanned, is diminishing. Although the System z and z/OS platform provides a solid foundation for IT organizations, technologies that address new challenges will continue to be developed. Recently created technology raises the bar and continues z/OS leadership in RAS. New tools are helping address the challenge and complexity administrators face when battling a system or application problem. Solid Foundation The evolution of System z* and z/OS is frequently highlighted by technologies developed to improve the system’s resiliency. After all, it’s rooted in enterprise computing, helping businesses run critical applications, so supporting the demand for high levels of availability has always been a key objective. Using a two-pronged, continuous-improvement approach, System z and z/OS developers focus on enhancements in both quality and RAS; reducing faults while increasing the fault-tolerance of the system. The results have created a generalpurpose business computing system that enables continuous planned availability times that are frequently Interesting Phenomenon One result of a system with everimproving, high levels of resiliency and availability is that few opportunities arise for administrators, operators and programmers to respond to system problems. Accordingly, support teams have less experience in dealing with such problems, which in turn, can reduce the efficiency or effectiveness of their recovery actions. Because problems are rare, when one does occur support teams are ill-prepared. 34 NOVEMBER/DECEMBER 2012 ibmsystemsmag.com/mainframe http://www.ibmsystemsmag.com/mainframe
