Presenter: Scott Chapman
Many customers only replace their mainframe every three to five years, and often make minimal, if any, configuration changes between replacements. Proper planning prevents poor performance. There are a many things to consider while deciding on the configuration that will take your business forward for the next three to five years. Some preparations are best started more than a year ahead of your planned upgrade. Others, such as running zPCR, are done before signing the purchase order and still other activities may need to be done after you have decided on a configuration but before implementation.
In this session, Scott Chapman will share the insight he has garnered from years of planning processor upgrades. He’ll explain the basics of running zPCR, why you want to do so, and how you can use the output. Preparing for processor speed changes will be discussed. Finally, some thoughts will be provided about understanding the performance changes after the upgrade.
