A simple 11.2 DataPump export (EXPDP) at SCHEMA level (e.g. on SCOTT schema) can be shown to generate a number of DWxx (and also seen from P00x and ORAxx processes) traces in /diag/trace directory.
The traces are of the following nature:
*** ACTION NAME:(SYS_EXPORT_FULL_02)
KUPC: Setting remote flag for this process to FALSE
prvtaqis - Enter
*** 2010-07-15 23:00:23.133
prvtaqis subtab_name upd
prvtaqis sys table upd
*** 2010-07-15 23:00:23.831
kwqberlst !retval block
kwqberlst rqan->lagno_kwqiia 5
kwqberlst rqan->lascn_kwqiia > 0 block
Traces are typically < 100K in length. If the EXPDP run was successful the traces contain no error messages, if EXPDP raises an internal 600/7445 or other errors the traces might contain some equivalent information.
