Just a couple of questions regarding you approach.
- Why not use the REMAP_TABLESPACE option in datapump rather than having to extract the DDL and manually recreate the objects.
- If you do use the DDL approach I'd suggest just creating the tables first, then import the data only and then create indexes/constraints as this should quicker.
Another possiblty is also to use the COPY command which will cope with your LONG columns and then rename the objects afterwards rather than using expdp/impdp.
Cheers,
Ian

Good Morning,
I've got a requirement to move about 300GB of table and index data from the current tablespaces into new tablespaces. There is a physical standby in place. The standby is located in another city. The database is 7TB in size. I am running Oracle 10.2.0.4 on AIX 6.1.
The standby is currently mounted with the STANDBY_FILE_MANAGEMENT initialization parameter is set to AUTO. We are not using ASM.
I'd like to get a sanity check on the plan I've put together.
Stop the application
Create the new tablespaces and datafiles --> this should propagate to the
standby
Get table and index DDL using dbms_metadata.get_ddl
Export tables using datapump
Drop tables and indexes --> this should propagate to the standby
Edit DDL to recreate tables and indexes in new tablespaces
Run create scripts --> this should propagate to the standby
Import tables using datapump --> this should propagate to the standby
All tables will remain in the same schema.
Comments appreciated.
