JCO trace

SAP JCo offers two different ways to write trace files.

1. Set the two options -Djco.trace_level= -Djco.trace_path= when you start the JVM.

2. Call the methods JCO.setTracePath(String directory_of_trace_files) and JCO.setTraceLevel(int trace_level) in your Java program.

In both cases files of signature JCO*.trc are created in the defined directory directory_of_trace_file. The quantity of log information can be adjusted with the trace level. The additional logging that is switched on for certain trace levels is described below. For error diagnostic the trace level 5 is recommended.

• 0: no trace files are written

• 1: logging of the SAP JCo Java API is switched on

• 3: logging of the SAP JCo JNI API is switched on

• 5: important information for error diagnostic is switched on
