Please respond
to ORACLE-L
Thanks so much for the info, Stephane.....I wonder if there will be
problems
arising about compatibility issues
between export from 9.2.0.3 database using the 9.2.0.3 export utility to
import onto 9.2.0.2 database
using the 9.2.0.2 import utility.
Any ideas about this ??
Regards,
Samir

Samir,
The general rule concerning this common problem is that you can import
into a database version n data exported from version n - 1, but that
importing into version n-1 data extracted from version n requires using
export of version n-1 against the database at version n (otherwise imp
screams). It assumes of course that you havn't made an extensive use of all
the novelties from version n, either in terms of structure, or in terms of
calls to arcane SYS packages which don't exist in version n-1. This doesn't
seem to be your case however.
There is an additional glitch, which is that exp makes use of tables
(dictionary tables) which evolve over time. Before running export of
version
n-1 against a database at version n, you may have to run (as SYS) a special
catalog script, usually called catexpsomething.sql, where something
represents the version of the export utility you want to use (n-1) and
which
you will find under the usual $ORACLE_HOME/rdbms/admin.
HTH,
