Parallel Data Pump Import

edited Nov 29, 2019 4:04AM in Database Utilities (MOSC) 6 commentsAnswered

Hi! We have a new Oracle database that is version 12.2 Enterprise Edition. We are using expdp to export data from old DB (10g) and impdp to import to new one. The data size is quite large (about 500GB after export) and took 15 hours to export. We are running the import now and it took 40+ hours and not yet finish, still loading the indexes. I have a few question on the import plus possibility to make use of parallel import after reviewing Parallel Capabilities of Oracle Data Pump (Doc ID 365459.1).

1. We have stopped the import due to server issue and need a reboot. The import job was put to stop with STOP_JOB=IMMEDIATE. Then close the database and reboot the server OS. Then attach the job again and restart. Will it be difference comparing with the job was done without stopping and resuming?

Howdy, Stranger!
