impdp multiple partitions in same table TM-CONTENTION issue

edited Jun 14, 2020 5:08AM in Database Utilities (MOSC) 7 commentsAnswered

I have a very large table to migrate with 2.6 trillion rows and about 100tb in size. it is in a daily interval partitioned table with 180 days of rolling data. i am unable to do multiple impdp jobs at the same time into what is a daily interval table as I get "enq: TM - contention" on a 2nd job. below is my .par file for the jobs. looking for a way to do in parallel with some sort of reasonable performance. I had a problem setting up the table with current partitions from the current database as the table would not then allow new partitions to be created as it was ( internally )  a range table ( not daily interval ) table at that point.

Howdy, Stranger!
