Task 5: (Optional) Restore Tablespaces to Read/Write Mode

Make the transported tablespaces read/write again at the source database.

The following statements make the sales_1 and sales_2 tablespaces read/write: 

ALTER TABLESPACE sales_1 READ WRITE;
ALTER TABLESPACE sales_2 READ WRITE;

You can postpone this task to first ensure that the import process succeeds.
