Kumar,  

You can't copy the datafiles between OSs unless they are binary compatable, with Windows and any
flavor of Unix are not. Also, you will have problems trying to export from 9i and import to 8i. You need
to run the export using 8i executables, or at least I could never get it to work any other way. Is there
a reason you can't install 9i on the Linux side? Also, if you are saying that both "machines" are the
same hardware ("dual boot"), how do you expect to get the .dmp file from one "side" to the "other side"?
Do you have some network storage somewhere?  

Good Luck,

Dennis,
In my case Net8 connection is not feasible because I have both OS Windows 2000/ Linux on the same machine using dual boot. So the only option for me is to export the required user from Windows database and then import from Linux database. But please note that I have source database Windows 2000/9i, but the source database is Linux/8.1.6. Can this be any problem for export/import.

Recently I copied a database from a Window machine to another window machine by copying the database files, redo log file, control files etc to target machine in the corresponding directory and just created a service on the target machine by using oradim and it worked fine. Is that possible if you want to move the database and other files of Windows OS database to a Linux OS database and then use svrmgrl to do something similar to get windows database working on Linux. I know for this to work, I need to recreate or make changes to control file.

Thanks.

   Ummm . . . are you using any 9i features? I'm assuming you have considered using 9i on Red Hat. Sounds like probably use the 8i export function to create the export file. I'm assuming the data involved is small enough to make export/import practical. If you create a Net8 connection, you can just copy the data.
