Hi Praveen,

SAP instances are defined during the installation of the SAP system.

The term “instance” is often used synonymously with “server” or “application server” in the SAP system. This depends on the selected installation environment. You can install multiple instances on one application server.

An SAP instance defines a group of resources such as memory, work processes and so on, usually in support of a single application server or database server within a client/server environment. Application servers share the same memory areas and are controlled by the same dispatcher process.

HI,

it is an administrative unit that groups components of an SAP R/3 system that provide one or more services.

These services are started and stopped at the same time. All components belonging to an instance are provided with parameters using a common instance profile. A central SAP R/3 System consists of a single instance that includes all the necessary SAP services.
