Performance Optimization managed services are used by many mainframe users in order to maximize the use of resources, increase application availability, and optimize performance. There isn't one single big button to push - these recommendations take time to develop, deploy, and measure. These optimizations cover overall system configuration, IO priority, WLM Policy review and changes, batch recommendations for splitting or changing the batch cycle to avoid big spikes.
The main technical recommendations executed which produced the most results are explained. This are usually the WLM policy review and changes as well as logical CPU configurations and CPs for the LPARs. This can include application modernization (i.e., update of COBOL or PL/I compliers).
This session showcases a successful assessment and includes the recommendations implemented for this transformation project as well as the before and after results scenario.
