Whatever the case may be,
there are only two methods.
1. Use lower version of exp to export and lower version of imp to import
or
2. install version of exp/imp views by running catexp.sql
If you want to export/import 9.2.0.6 database using 9.2.0.7 version of exp, then run catexp of 9.2.0.6 against 9.2.0.7 database.
Search the forum for more details.

Many Thanks Mahesh!!!

However, two more questions here. (although i will definitely serach the forum for Details)

1)Will "Executing catexp of 9.2.0.6 Database will overwrite (drop /create) the Objects required of export/import in existing 9.2.0.7 database?

2)
Is the Export or Import utility version also matters here?
i have two databases where

DB1
Database version : Oracle9i Enterprise Edition Release 9.2.0.6.0
IMP Utility : 9.0.1.5.0

DB2
Database version : Oracle9i Enterprise Edition Release 9.2.0.7.0
IMP Utility : 9.2.0.7.0

Please suggest.
Thanks and Regards
Pratap

1.) YES. You need to re-run catexp of 9.2.0.7 again for further operations wiht 9.2.0.7. You may not want to do this in production (though harmless, do not do it, if you are not comfortable).

Quote:

Database version : Oracle9i Enterprise Edition Release 9.2.0.6.0
IMP Utility : 9.0.1.5.0

You mean to say that,
Your datbase version and it local imp version are different?
I would prefer to have them in same version.

concept is use the lower version of exp/imp tools against higher version of database
or
Run catexp.sql
