The profile files are automatically created during installation. After
installation is complete, the profile files are stored at operating system
level in the directory: \usr\sap\\SYS\profile. Thisdirectorycanbe
read by all instances of an SAP system using the share or mount technique.
The SAP system has three system profiles. These are:
• Start profile
• Default profile
• Instance profile
In principle, you can change these files with operating system resources
(editors). In doing so, the user must ensure himself or herself that the
changes are performed correctly. Incorrectly set parameters can lead to
the system not starting. It is far more convenient and safer to change the
profile parameters using the resources in the SAP system.
Show the profile files at operating system level. To do this, go to the
directory g:\usr\sap\\SYS\profile in Windows Explorer.
Make a backup of the profile files. To do this, create a separate directory
and copy the files there.

The instance-specific start profile (START_), specifies for each instance which processes are to
be started. These are, for example, the message server and the dispatcher.
