locally. Use
- startsap name= nr= SAPDIAHOST= to start an R/3 instance and
- stopsap name= nr= SAPDIAHOST= to stop an R/3 instance (the executables
sapstart.exe, sapsrvkill.exe and sapntwaitforhalt.exe must be in the same directory)

To provide a stable startup procedure, a parameter read sequence (also known as
the parameter replace sequence) is defined during startup as follows:
R/3 processes read the appropriate parameters from the R/3 kernel, from the NT
system environment variables, and from the NT Registry environment variables.
The default profile
“\\\sapmnt\\SYS\profile\default.pfl” is read. Profile values already defined in the
R/3 kernel are replaced with the values in the default profile.
The instance profile
“\\\sapmnt\\SYS\profile\__” is read.
Profile values already defined in the default profile or in the R/3 kernel are replaced
with the values defined in the instance profile.
This procedure ensures that system parameter values reflect not only the instance
profile but also the values in the default profile and the R/3 kernel.
The SAP service reads only the start profile and the default profile. The R/3 kernel
(disp+work.exe) reads only the default profile and the instance profile. If you
change the default profile, you must restart the SAP service (including the R/3
instance). If you only change the instance profile, you only need to restart R/3 using
the MMC.

R/3 work directories contain trace files and error files for messages relating to the
startup of work processes. Each R/3 instance has a separate work directory
containing information that may not be found in the R/3 System log.
The work directory files are initialized in chronological order. During startup, the
SAP service executable SAPSTARTSRV.EXE writes:
Database logs to the file STDERR1
Message server logs to the file STDERR2
Dispatcher logs to the file STDERR3
To define the level of information written to the developer trace files, set the profile
parameter “rdisp/TRACE” in the instance profile. The possible values for this
parameter are:
0: Write only errors (no traces)
1: Write error messages and warnings (default)
2: Write error messages and a short trace
3: Write error messages and the complete trace
