Tracing an Oracle EXPDP

With the EXPDP command, you can add the TRACE= parameter.

The TRACE parameter takes a 7-digit hexadecimal mask.  The first three digits enable tracing for a specific Data Pump component, while the last four digits are usually: 0300.

Normally, TRACE=480300 is sufficient.

To trace EVERYTHING (main component plus worker threads), use TRACE=1FF0300.

 

Taken from Oracle Document ID 286496.1:
