System Trace: Relevant Profile Parameters
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/. For default values and parameter documentation, see transaction RZ11.The trace parameters that you can set are as follows:
|
Profile Parameters |
Meaning |
|
rstr/buffer_size_kB |
The SAP trace (such as SQL trace) writes the trace data to the trace files. For performance reasons, this is done via an internal buffer and not directly. The profile parameter rstr/buffer_size_kB determines the size of this buffer in kilobytes. |
|
rstr/filename rstr/max_files rstr/max_filesize_MB |
Since Release 6.10, the SAP trace stores the data in several files. These files are written to sequentially. The parameter rstr/filename sets the basic name of these files. There is always one file with the basic name. When this file is full (parameter rstr/max_filesize_MB), the file is re-named and a new file is created with the basic name. When the file is re-named, a number from 00 to 99 is added to the filename. The parameter rstr/max_files determines how many files there are in total. 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.
