Profiles 

Purpose

SAP profiles are operating system files that contain instance configuration information. SAP systems can consist of one or more instances. Individual configuration parameters can be customized to the requirements of each instance. You can use these parameters to configure the following:

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

·         Which services the instance itself provides (work processes)

·         Where other services can be found (database host)

Features

The profile file is structured as follows:

# This is a comment in an SAP profile:

Parametername1 = Value1

Parametername2 = Value2

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

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

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

UNIX systems:/usr/sap/<SID>/SYS/profile

Microsoft Windows NT systems:\\<SAPGLOBALHOST>\sapmnt\<SID>\sys\profile\

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

All host computers in an SAP System can access these profiles. More than one instance can use the same profile at the same time. Separate profiles are not required for each instance.

Use the Computing Center Management System (CCMS) to maintain configuration profiles. This means that you should not edit the active profiles directly at operating system level.
