One of the challenges in reporting on large amounts of data is, well, reporting on large amounts of data! The process of collecting, storing, and subsequently displaying thousands of objects is a daunting task for any performance management tool. Certain types of data lend themselves to this quandary, and WebSphere MQ queues in large Z/OS queue managers is certainly one of those cases.
Large Z/OS queue managers can easily accommodate 1000’s of WMQ objects. I have seen customer environments which are in excess of 10,000 objects in a single queue manager. Obviously, there is a significant cost in retrieving and displaying such a large amount of data.
Understanding the requirement to reduce the TCO of system management tools, Tivoli R&D has recently delivered functionality which significantly decreases the CPU required to process large amounts of data. CPU reductions of up to 85% have been observed when executing user requests returning a result set of 16mb.
This enhancement is available for Z/OS and distributed system based OMEGAMON / ITM / ITCAM agents. The following table outlines PTFs delivering this function.
