Hi Experts.
We have been alerted that an RFC user configured in the XI (3.0 SP14) is changing the work processes trace level to full trace in the R/3 system where it connects.
This should be creating huge trace/log files in the R/3 system which could be affecting the performance.
However, we have other XI server pointing to the same R/3 (in a different SLD) and the RFC user is not doing this, which makes me think that in the first mentioned XI we have wrongly set any parameter/configuration.
I have already checked the SM59 and the trace option in the RFC is not enabled.
Do you have guys any idea about any paramter to specify the trace level used when a RFC connection is stablished?
Thanks in advance.
Cheers.
Hi ,
System Logs
In accordance with the dialog system, the SAP Gateway records system logs for all error situations. You can evaluate the system logs with the usual tools.
Traces
In addition you can record detailed traces. To do this you have to set a trace level in the parameter rdisp/TRACE :
rdisp/TRACE = 0 no trace
rdisp/TRACE = 1 error trace
rdisp/TRACE = 2 complete process trace, short data trace
rdisp/TRACE = 3 complete process trace, short data trace
The traces are to be found in the following files:
Process
Trace File
Gateway read process:
dev_rd
Gateway monitor:
dev_gwmon
All trace lines describing an error begin with ***.
All trace lines corresponding to a system log (syslog) begin with ***LOG, followed by the system log number and the version of the variable parts of the system log.
You can Activate the trace function for the gateway and for external programs.

Trace Functions
Return Codes
For troubleshooting purposes, it is often helpful to understand the meaning of the return codes. You will find a list of the most important error codes in the section Error Codes.
If an error occurs, you can view the error codes on the initial screen of the Gateway Monitor. If you choose F1 help, a list is displayed.
The CPI-C return codes and the return codes from the SAP Gateway are listed in the SAP note 63347.
SAP Gateway Memory Problems
Some error messages and trace entries indicate gateway problems as regards memory allocation. For more information about this, see Memory Management of the SAP Gateway and Parameters for Resource Management
Error Starting CPI-C Programs
Local Programs
The gateway starts locak CPIC programs using fork/execlp. This implies that the program must be located in the search path of the (gateway) UNIX ID and must be executable for the (gateway) UNIX ID.
You can test this by logging on with the gateway ID and using the command which checking whether the program you want to start is in the search path of the gateway ID: Enter which <program>.
Remote and Registered Programs
For information about errors that may occur when starting remote and registered CPI-C programs see Errors When Starting CPI-C Programs.
