“We have production and development in different LPARs so they can’t impact each other’s performance. Right?” Well… that’s not entirely true: there are a number of ways that one LPAR’s activity may impact another LPAR’s performance. While some of these ways are examples of poor configuration decisions, most are a result of necessary trade-offs while running in a shared environment. If you’ve ever wondered how one LPAR may impact the performance of work in another LPAR or wondered how to best protect LPARs from such interference then this session is for you. Scott Chapman will discuss performance measures that might tip you off to a problem as well as configuration options that can help protect your most important systems.
Scott Chapman has over three decades of experience in the IBM mainframe environment. Much of this experience has focused on performance, from both the application and systems perspective. He's written COBOL application code and Assembler system exit code. He’s ported Java applications to the mainframe as well as developed unique Java applications. His mainframe responsibilities have spanned application development, performance tuning, capacity planning, software cost management, system tuning, sysplex configuration, WLM configuration, and most other facets of keeping a mainframe environment running effectively. At Enterprise Performance Strategies, Scott has helped customers around the world understand and improve the performance of their z/OS systems. He is one of the principal designers and developers of the Pivotor performance reporting product. Scott has spoken extensively at user group meetings and was honored to receive the Computer Measurement Group's Mullen award, and also co-authored a CMG best paper. He has also received SHARE’s Best Session Award multiple times and SHARE’s Distinguished Speaker award. Scott is a founding steering committee member of the Central Ohio Mainframe User's Group.
