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).

Features

This profile file is structured as follows:

# This is a comment in a SAP profile:

Parametername1 = Value1

Parametername2 = Value2

Parameter names that logically belong together have a common root. For example, the root of parameters that control the dispatcher within an application server is: rdisp/ .

The parameter rdisp/wp_non_dia specifies how many dialog work processes are started by the dispatcher.

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

Windows NT systems: \\sapmnt\\sys\profile\

( = SAP system name and = name of the NT machine on which the global profile directory is physically located)

All hosts in an SAP System can access these profiles. It is possible for several R/3 instances to use a single profile simultaneously. Separate profiles are not required for each R/3 instance.

You should maintain setup profiles using the Computing Center Management System (CCMS). You should therefore not edit the active profiles directly at operating system level.
