OpenVMS Symposium Abstracts Special Overflow Session Room - Hollis Room – Susan Skonetski Overall Block Abstract: This room has been designated for sessions that were too important to be left out but either did not fit in easily with the defined blocks or the sessions needed additional time. Title: Practical Uses of OpenVMS’ MONITOR Utility Speaker: Bart Z. Lederman Abstract: MONITOR delivers powerful capabilities for performance troubleshooting, capacity planning, and load balancing, and is the utility most used within the OpenVMS Performance Expertise Center during testing and investigation to collect data. This session offers a series of practical examples based on experience. You will learn how to use MONITOR effectively as an interactive tool and for collecting, reporting, and playback. This session will benefit users of OpenVMS, including those who have only a cursory knowledge of MONITOR. For those who are already experienced with using MONITOR interactively, this session will bring to light some of the less obvious aspects of MONITOR that have proven the most useful in actual use. Attendees will be able to immediately apply these techniques on their own system. Title: Performance Management and OpenVMS Tools Speaker: Bart Z. Lederman Abstract: There is more to getting good performance from a system than “tuning”.

Title: Best Practices for OpenVMS Performance Speaker: Steve Lieman Abstract: Over the past several years and in conjunction with our partners and our largest customers, OpenVMS Engineering has helped create, shape, and define a set of best practices for managing the performance of large scale OpenVMS systems. This session will provide the technical details of what we have learned so far. Highlights include best practices for measuring the most business critical throughput and response statistics, the integration of business statistics with OpenVMS statistics and database statistics, and the design of an overall performance management process that will help you tie everything together on your most important systems using trending and before and after comparisons. Title: Boosting RMS Indexed File Performance Name: Elinor Woods Abstract: This session begins by identifying some often overlooked file and key definition characteristics that can significantly impact a file's performance and, if left unattended, could prevent a file from ever achieving the throughput it is capable of. Some of these characteristics include long chains of duplicate or deleted records and unnecessarily deep index trees. RMS indexed file internals are shared to explain how these characteristics may cause a performance bottleneck. After addressing these potential bottlenecks, the session describes some 'bells and whistles' that RMS offers that users can choose from that may boost indexed file performance. These include options that can reduce both I/O and bucket locking requests for both readers and writers (global buffers), as well as minimize record locking for readers (no query record locking). The session concludes with some assistance for getting started with enabling global buffers.
