The SAP profile contains R/3 setup information for an R/3 instance.

The R/3 System can consist of one or more instances. For example, an R/3 System with a single instance containing only a central server, or a client/server system containing two or more separate instances.

Individual setup parameters can be customized to the requirements of each instance.

These individual parameters allow you to configure:

• The runtime environment of the instance (resources such as main memory size, shared memory, roll size)

• Which services the instance has available (work processes)

• Where other services can be found (database host).
