1. Run ORacle 8i exp against Oracle 9i database from ORACLE_HOME of 8i. IF you encounter any errors,run catexp.sql from Orale 8i ORACLE_HOME/rdbms/admin/ as sys@Oracle_9i_database using sqlplus
and then rerun the Oracle 8i exp against the 9i database.

2. Import the the 9i dump file into 8i database using 8i imp. Use appropriate NLS_LANG setting when importing,preferrably the same one you used when exporting.

3. Rerun ORacle 9i's catexp.sql against 9i database if you have run oracle 8i's catexp against the 9i database previously as mentioned in step 1.

Yuvraj,
I had no problem doing that on Unix. Besides,how are you executing the exp across the higher version..It should be something like

1. In 8i environment

export ORACLE_SID=8i_SID

i) Run 8i's catexp against 9i database

sqlplus sys/password@Oracle_9i_string @$ORACLE_HOME/rdbms/admin/catexp.sql

ii) Use 8i exp against 9i database

exp user/pass@Oracle_9i_connect_string owner=...

iii) Import into 8i database using 8i imp

imp user/pass file= fromuser= touser= ...

2. In 9i environment

export ORACLE_SID=9i_SID
i) Run 9i's catexp.sql against 9i database to restore the 9i dictionary views

sqlplus sys/password@9i_connect_string @$ORACLE_HOME/rdbms/admin/catexp.sql

People,

What if I don't have Oracle 9i and my partner wants to give me a dmp file? Should I be able to import the file without problems? What my partner's suppose to be aware of when creating the dmp file?
