environment, successfully complete the entire Oracle database object and data migration work. It is worth noting that when we export Oracle objects and data, the default is the original Oracle database table space and database user name, if we want to specify a different table space and database user objects in the new database server, then we need to replace the generated SQL script, and specify a reasonable tablespace and database user in the first step.
