What is SAP Profile?

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)

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\

Types of SAP Profiles:

During installation, three profiles are created in the file system:
·  DEFAULT.PFL            ------------Default profile
·  START_<Instance>     ------------Start Profile
·  <SID>_<Instance>      ------------instance profile

These profiles contain the parameters that determine the operating system resource usage of the instance, for example, the number of work processes, the buffer sizes.

You import and activate these profiles using the profile maintenance tool.

This profile parameters are maintained in RZ10.
