A schema import is specified using the
SCHEMAS parameter. In a schema import, only objects owned by the specified schemas are loaded. The source can be a full, table, tablespace, or schema-mode export dump file set or another database. If you have the
DATAPUMP_IMP_FULL_DATABASE role, then a list of schemas can be specified and the schemas themselves (including system privilege grants) are created in the database in addition to the objects contained within those schemas.
Cross-schema references are not imported for non-privileged users unless the other schema is remapped to the current schema. For example, a trigger defined on a table within the importing user's schema, but residing in another user's schema, is not imported.
