Configuring the Trace File (SAP Library - BC ABAP Workbench Tools)

Configuring the Trace File

Profile Parameters

The system requires the two following profile parameters to be set in order for the performance trace to work:

rstr/file: The pattern for the path name of the trace file.

rstr/max_diskspace: The maximum size (in bytes) that can be assigned to a trace file.

The recommended default size is 16 384 000 (16 000 KB). However, you can change the name of the trace file at any time using Transaction ST01. This allows you to work with several trace files at once and prevent performance data from being overwritten.

rstr/fileset/allowed: This parameter determines whether users should be allowed to change the name of the trace file. The default value is "1", that is, it is possible to change the name of the file. If you change the value to "0", users cannot change the name of the file.

These parameters are set when the system is installed. You can also change them using Transaction RZ11.

Changing the Name of the Trace File

The name of the trace file into which the performance trace writes entries is predetermined by the system administrator. If the profile parameter rstr/fileset/allowed is set to its default value, you can change the name of the trace file in the profile parameter rstr/file using Transaction ST01.

Procedure

Start Transaction ST01, either using its transaction code, or by choosing Administration ® System administration ® Monitor ® Trace ® SAP System trace.

Choose Edit ® New file.
A dialog box appears in which you can choose any character for the third-last character (as long as the profile parameter rstr/fileset/allowed is set to "1").

Enter a character.
You can enter any character from 0 through 9 and A through Z.
