SAP Profiles

SAP profiles are operating system files that contain instance setup information. SAP Systems can consist of one or more 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).

SAP profiles are stored in a special file directory. This directory can be made accessible from all hosts depending on current needs:

UNIX systems : /usr/sap//SYS/profile

This profile determine how many work process of a particular type are started.
An important part of this instance profile sis that definition of the size of the main memory areas of the R/3 System. The profile also contains settings of logon parameters and log size.

They also define the available instance resources (main memory, shared memory, roll memory and so on), and how to allocate memory to the SAP application buffers.
