Overview/Description
A service is a grouping of related tasks within a database with common functionality, quality expectations, and priority relative to other services. It provides a single-system image for managing competing applications running within a single instance and across multiple instances and databases. Using standard interfaces, such as the Database Configuration Assistant, Enterprise Manager, and SRVCTL, services can be configured, administered, enabled, disabled, and measured as a single entity. This course provides an introduction to services and discusses how to configure...
