increasing number of "..." to change the blinking cursor. New: Exp/imp is very easy to use, but the only confirmation is that the speed is too slow. If the data in a table has hundreds of millions of records, it is often a long time to stop importing and exporting the data in this table, however, the new tool expdp/impdp is provided from Oracle 10 Gb, which provides high-speed parallel and big data migration for Oracle data.

The skip_constraint_errors option of Oracle impdp skips the unique constraint error. In the past, impdp imported to an existing table has a unique index, and the data to be imported has a unique conflict with the current data. the general solution is to first Delete the unique index, import the duplicate data, and then re-create the index, or import the table as another table name, and then import the joine
