Activating / Deactivating Developer Traces from the System Profile & Command Line

Activating / Deactivating Developer Traces from the System Profile:

You can also set trace options instance-wide with the rdisp/TRACE=<n> option. The trace values are the same as those in the list above.

Setting the trace parameter in the instance profile of a particular server activates developer traces only in that server.

Setting the parameter in the default profile would activate traces in all servers (excepting those whose instance profiles specify a different parameter value).

Activating / Deactivating Developer Traces from the Command Line:

You can also turn tracing on, or set the various trace levels by entering the appropriate commands in the command line. This is possible in all SAP programs. Typically, you must add these options to the start commands for SAP processes in the start-up profile of an instance of your SAP System. 

The following criteria are available:

• TRACE=0: No trace

• TRACE=1: Write error messages in the trace file.

• TRACE=2: Full trace. The trace entries that are actually written can vary with the SAP program that is being traced.

• TRACE=3: Additionally, trace data blocks.
