Some minutes ago I've tried to do an export but I get the following error (AIX system):
Additional information: 3 ORA-31693: Table data object "XX"."TABLE_NAME" failed to load/unload and is being skipped due to error: ORA-31617: unable to open dump file "/dir/back/dump/dump_xx_04.dmp" for write ORA-19505: failed to identify file "/dir/back/dump/dump_xx_04.dmp" ORA-27037: unable to obtain file status IBM AIX RISC System/6000 Error: 2: No such file or directory
What could the reason for this behaviour be?
I've read in some blog that using just
%U that the export is actually slower. Is that true?
