Uses

These charts show how z/OS LPARs use the real memory in central storage. Lack of sufficient real memory to handle workload requirements can result in excessive paging between central storage and auxiliary storage—which results in less than optimal performance. These charts help to understand how real memory is used, and can assist in identifying systems that are experiencing performance degradation due to insufficient central storage to satisfy workload requirements.
