Example 3-2 Performing a Schema-Mode Import
> impdp hr SCHEMAS=hr DIRECTORY=dpump_dir1 DUMPFILE=expschema.dmp EXCLUDE=CONSTRAINT,REF_CONSTRAINT,INDEX TABLE_EXISTS_ACTION=REPLACE
EXCLUDE parameter filters the metadata that is imported. For the given mode of import, all the objects contained within the source, and all their dependent objects, are included except those specified in an
EXCLUDE statement. If an object is excluded, then all of its dependent objects are also excluded.The
TABLE_EXISTS_ACTION=REPLACE parameter tells Import to drop the table if it already exists and to then re-create and load it using the dump file contents.
