Question: I want to move all db objects
from one schema to another schema.
How do I copy an Oracle schema?
Answer: To clone a schema, I would use
either of these methods:
- Copy schema with Data Pump export/import: Use
expdp to export the old schema and import into the new
schema using
impdp with the "remap schema" parameter. The Rampant
Oracle Utilities book has full examples of copying a schema.
- Copy schema with CTAS: Create the new schema owner,
use
CTAS to copy the tables, and then punch & re-add constraints
and indexes using
dbms_metadata. Parallelized CTAS is a faster way to copy a
schema than using Data Pump, but the copy steps are more
complex.
See the link for a working example of a
script to copy an Oracle user.
