摘要

The paper shares some challenges that some Application Capacity Management team had during a re-platforming and the way how to overcome them. The raw capacity estimation model was built to estimate AIX frames capacity needs. The capacity planning process was adjusted to virtualized environment. The essential system, middleware and database metrics to monitor capacity were identified; business driver correlated forecast reports were built to proactively tune entitlements; IT-Control Charts were created to establish dynamic thresholds for physical processors and 10s usage. A Capacity Council was established.
