Got a Problem with Transaction Processing in a Timely fashion?

Verna Bartlett, DataKinetics

You will learn the many ways in which in-memory tables can boost mainframe performance, can be used together with DB2 for optimized data access, and can be used to provide increased flexibility and responsiveness to market changes.

DASD I/O Analysis from the Workload Point-of-View

Peter Enrico, EPS Strategies

When analyzing DASD I/O performance, many performance analysts concentrate on I/O measurements from a logical volume and control unit point-of-view. This “how to” session will explain many of the measurements available for valuable insight into a large influencing component to workload performance by examining from a workload perspective.

Exploring the SMF 113 Processor Cache Counters and LSPRs

Peter Enrico, EPS Strategies

The new SMF 113 measurements are designed to provide insight into the movement of data and instructions among the processor cache and memory areas. These measurements will be invaluable to help quantify the net effect of everything from turning on HiperDispatch to making critical application change.  SMF 113 measurements have become the basis for IBM’s LSPRs for processor sizing. You will learn the concept of processor caching on zArchitecture processors, the counters available in the SMF 113 record, formulas that make the counters come alive, examples of how the counters could be used.

Platform Performance Management Functions of the New IBM zEnterprise Mainframe

Glenn Anderson, IBM

The IBM zEnterprise Unified Resource Manager enables the deployment and management of the heterogeneous hardware resources of System z ensembles through a single interface that can be tied to business requirements. We begin with a discussion of the contents of a zEnterprise ensemble and the suites of functionality available to manage one. This presentation will examine the capabilities and basic implementation of Platform Performance Management for zEnterprise.

Connecting the Dots: LPARs, HiperDispatch, WLM, zIIPs and zAAPs

Glenn Anderson, IBM

Your z/OS System and WLM manage different types of transaction and server workloads with multiple dispatchable units - TCBs, SRBs, enclave SRBs. Multi address space application scenarios use a combination of velocity and response time goals across multiple WLM service classes to manage performance. HiperDispatch now plays a role in how ready work gets dispatched in z/OS, as well as how PR/SM dispatches logical CPs. In addition, some of these workloads are also eligible to be redirected to zIIP and zAAP specialty engines. Let’s connect all these pieces together to understand WLM management, what makes work eligible for zIIPs and zAAPs, and the role of HiperDispatch.
