# Oracle Enterprise Manager

> Oracle Enterprise Manager (OEM) is an on-premises management platform for Oracle IT infrastructure and applications. Its REST APIs and the EM CLI provide programmatic access to monitoring, administration, and automation — targets, metrics, incidents, blackouts, credentials, users/roles, jobs, patching, deployment procedures, and database lifecycle management. APIs are served from the customer's own Oracle Management Service (OMS) at https://{emHost}:{emPort}/em/api using HTTP Basic authentication.
