Preparing Database Upgrade 11G, 220.127.116.11 to 12c, 18.104.22.168. Our first planned activity is to perform a DataPump export. In the past the export has taken almost 24 hours, and the import has taken over 48 hours. Needless to say this is unacceptable to our customer.
Should mention we have a 2 node RAC Database, that has 24 cores. Plan to use parameter I haven’t used before. Database is reasonable large (~12TB)
Anyone have experience setting these parameters cluster=Y Parallel=48?
