Background documentation System Trace: Relevant Profile Parameters Locate the document in its SAP Library structure

With system profile parameters, you can set the maximum size of the SQL and system trace files and specify its path name. All trace parameter names begin with the string rstr/. You can display the standard values and the parameter documentation in transaction RZ11.

The trace parameters that you can set are as follows:

Profile Parameter



The SAP trace (for example, SQL trace) saves the trace data in trace files. To minimize the effect on system performance the data is saved in an internal buffer, and not saved directly. Profile parameter rstr/buffer_size_kB  determines the size of the buffer in kilobytes.


The SAP trace (for example, SQL trace) stores the data in several files that are written sequentially. Parameter rstr/filename defines the base name of these files. There is always one file with this exact name. Wenn die Datei voll ist (Parameter rstr/max_filesize_MB), wird die Datei umbenannt und eine neue Datei mit dem Basisnamen erzeugt. When the file is renamed, a number between 00 and 99 is assigned to the file name. Parameter rstr/max_files determines the maximum number of files. If this number is exceeded, the files are overwritten.                                                      



The System maintains additional trace parameters which you should not change.

You can obtain further information on the parameters using transaction RZ11.
