09:30 - 10:30  Application Performance Management, From 30,000 Feet Down to Ground Level

Speaker: Doug Dittrich, Vantage Performance Solutions

In a complicated client/server and distributed environment it is more important than ever to relate business objectives (Service Level Objectives) back to transaction threads that span multiple platforms, networks, and client interfaces. This presentation provides a methodology for using Application Performance Management solutions for collecting and analyzing network data. With this data performance view, engineers can set thresholds that match business objectives enabling them to focus on the exceptions. In addition, when a performance exception occurs you will see how Application Performance Management simplifies the process of identifying the performance issue - whether it is the network, the server, or the application, down to the source statement or SQL call level.

10:45 - 11:45 Get Real! The Importance of Realism for Web Site Capacity Assessment

Speaker: Philip Joung, CAW Networks and Spirent Communications

Web system capacity assessment often carefully emulates user behavior. User behavior dramatically affects system performance, but comprises only half the story. Network realism plays a major role in system performance, and must be considered for a reliable reflection of performance in the real world. Network realism includes packet loss, link latencies, millions of IP addresses and protocols. Philip’s presentation will show the benefits gained from capacity assessment. His presentation will cover the impact of both user and network behavior and include an explanation of how they affect performance. Actual case study results will be provided.

11:45 - 1:00  NCCMG Business Meeting - **LUNCH WILL BE PROVIDED**

 

1:00 - 2:00  Using the z/OS SNMP MIB to Solve Performance Problems

Speaker: Nalini Elkins, Inside Products

The new z/OS TCP/IP stack (z/OS 1.2) has a greatly enhanced SNMP MIB to allow the systems programmer to do diagnostics for the TCP/IP stack and sessions. The SNMP MIB includes hundreds of variables to analyze the core IP protocols (IP, TCP, UDP, and ICMP) plus many other variables not available by any other means. Data such as backlog for Listener sessions or IP packets dropped for CSM memory shortages provide invaluable sources of data to monitor for z/OS performance and troubleshooting.

The z/OS 1.2 SNMP MIB also contains information to analyze OSA Express performance and throughput. This information is not available through Netstat commands or via SMF records. OSA Express provides high speed access for FTP and other critical traffic - knowing the throughput and utilization of this expensive and critical resource is mandatory for a systems programmer.

The many variables and their uses will be discussed in this presentation.
