My production environment is in 9.2. My development crashed. Then I installed the software 9.1 on sunsparc (which is the version we have).
When I want to import the (full mode) taken from production (9.2 version) into development (9.1 version), it is giving errors. Is it because the versions aren't compatible? Is it mandatory to upgrade the development database also? (I followed the procedure of creation of user and tablespace and other).
Use the 9.1 export utility against the 9.2 database. Your errors are because the 9.2 dump file contains information the 9.1 import utility does not understand. Create an entry in your 9.1 tnsnames.ora config file which points to the 9.2 database. Then start the 9.1 export utility. For the username, provide "user/pass@tns_entry". The 9.1 export utility will connect to the 9.2 database and create the dump file. At that point, you won't have any problems importing into the 9.2 database.
