The next meeting of the NY Metro NaSPA Chapter will be on Tuesday, 20 March 2012 in room 1219 at the IBM Building at 590 Madison Avenue, New York City, from 10:00 AM until 4:30 PM. Please note the change in registration at the end of this append. Sessions for the day include:
"How do you do What you do When You're a z196 CPU?", Bob Rogers, Distinguished Engineer, IBM If you've ever been an assembler programmer, you'll enjoy this look inside IBM's latest mainframe processor. This presentation includes an overview of the processor cache, the elements of the instruction pipeline, and other aspects of instruction execution. It focuses on the IBM zEnterprise processors (z196) and is an update to presentations the speaker has given in the past on the workings of earlier IBM System z processors. This version of the presentation covers topics such as the high-frequency pipeline, instruction cracking, register renaming, out-of-order execution, co-processors, TLB enhancements and other interesting aspects of the z196 processors. About the speaker: Bob Rogers is a z/OS designer and evangelist. An IBM Distinguished Engineer, he frequently presents at SHARE and other conferences. "Detecting and Diagnosing Soft Failures Using z/OS Predictive Failure Analysis and Runtime Diagnostics", Bob Abrams, Senior Technical Staff Member, IBM Predictive Failure Analysis (PFA) and Runtime Diagnostics (RTD) are two z/OS functions aimed at improving z/OS availability via the detection, avoidance and diagnosis of Soft Failures. This presentation starts by defining Soft Failures and describes how PFA analyzes specific data sources to identify changes in patterns compared to behavior learned from the system based on prior history. PFA is integrated with the z/OS Health Checker, offering many checks of system behavior, leading to the prediction of system activity that could lead to a system outage. We then describe Runtime Diagnostics, which is a z/OS function (new in z/OS R12) that can be invoked to analyze a system for "sick but not dead" types of problem symptoms, producing its response in a multi-line WTO response. An integration of PFA and RTD analysis introduced in R13 is also discussed. About the speaker: Bob Abrams is a Senior Technical Staff Member (STSM) at IBM in the z/OS Development area, celebrating 34 years at IBM this year. His focus areas include reliability, availability and serviceability (RAS) and problem determination issues for z/OS system software, including the z/OSMF Incident Log, Runtime Diagnostics features, and System z firmware. "High Availability Architectures for Linux in a Virtual Environment", Scott Loveland, Senior Technical Staff Member, IBM Linux virtual servers are increasingly being used to support critical applications in IBM System z server environments. As the mission becomes more important, so does the need to ensure its supporting infrastructure is highly available. But how? z/OS system programmers know the best practices for eliminating single points of failure for their systems, but may be unsure how to translate those techniques to the Linux world. Admins coming from a distributed Linux background may wonder how a virtualized environment on System z changes the game. And both groups may ponder how to best marry the Linux and z/OS worlds to maximize availability. Wonder no more! This session will cover a set of high availability architectures for Linux virtual servers (LVS), in the context of serving data to WebSphere applications (though WebSphere itself won't be the main focus). We'll discuss: Single points of failure in an LVS environment, probabilities of each, and the relative cost to eliminate them -- with examples of how to do so The power of virtualization to minimize degradation of service in the wake of failures, and to reduce the need for large clusters of redundant servers How software running on Linux virtual servers can work cooperatively with a Parallel Sysplex and z/OS data sharing groups Sample architecture specifics, including architectural decisions and tradeoffs, configuration options, and product technologies used About the speaker: Scott Loveland is a Senior Technical Staff Member in the IBM Poughkeepsie development laboratory. His career has spanned a variety of mainframe software technologies, ranging from z/OS to Linux for System z to various middleware products. His the Linux for System z integration test architect, and a frequent speaker at industry conferences and customer briefings. "Avoiding the Pitfalls of Managing System Logger", Andrew Sica, Advisory Software Engineer, IBM System Logger provides sysplex-wide logging capability to exploiters such as CICS Transaction Server, SMF, IMS Common Queue Server, and more. This session will talk about some of the common setup and tuning mistakes that can come back to bite you - and how to avoid them. We'll also discuss recent enhancements to the component, and give a glimpse of some future changes. About the speaker: Andrew Sica has been working in system logger development for the last 12 years. He is one of the co-authors of the "System Programmer's Guide to the z/OS System Logger." Registration: Due to a change in building access policies, registration is required . Please RSVP to [email protected] as soon as is possible if you are thinking of attending, but no later than Noon ET on Monday, 19 March. The meeting is open to non-NaSPA members and is free.
