It did! Can't believe it didn't occur to me that only specifying one file would be an issue with parallel > 1.

Previously even single process dp exports were slow. that was resolved by gathering missing dictionary and fixed stats.

thanks everyone! that's was a glaringly obvious mistake that i should have thought of.

Hi Chris,

Please let us know if that solved your problem. I am always intrigued as to what is going on. I vaguely remember a MOS note that explained tracing data pump exports, I can dig it up if needed. If nothing helps I would like to recommend use of session snapper to see what is going on on all participating processes, maybe correlated to file system/OS statistics.

Good luck,


Martin Bach
