DB export going slow
we are running an Oracle 12c (12.2.0.1 with, Patch 29019842) standard edition along with JDE. We are running exports on a regular basis.
Each Sunday we are restarting the complete database including the OS (Windows). The first export will start Monday night 11:00 P.M. and will finish after 3 hours, Tuesday at 02:00 A.M..
The second export is starting on Tuesday 11:00 P.M. and will finish on Wednesday 09:00 A.M.
So the second export, same settings and same amount of data, is taking 7 hours longer than the day before.
Memory max target is set to 12GB and memory target to 10 GB. On OS level, the process is allocating 7,5 GB.
