restore database in different file system [message #59677]

I backup database in WinNT using Recovery Manager.
Can anybody tell me how to restore it in Linux without using recovery catalog. I suppose it should be easy if destination filesystem would be like source filesystem - just put the files to the same places they were in WinNT. But I cannot put backup files to the places like c:aaaee in Linux.
Do I miss something? Can anybody help me?

thanks

i believe, the only way to move databases across the Operating systems is to export and import.
The RMAN backuppieces created in one OS cannot be used to restore in another OS ( windows -> linux)
( but u can use it to restore in the same OS but different version sunOS 7 -> sunOS 8).
Moreover u are actually looking into duplicating the database ( in windows) to linux.
RMAN duplication or clone requires that the filesytem used for backup ( in sourceMachine) should be available as 'local' filesystem in target machine.
like in unix, u can nfs mount the source:/backup to target:/backup and run duplicate commands in target.

Mahesh is right. You cannot use RMAN to duplicate databases across different platforms as the backup pieces are OS dependent. Export/Import is the only 'supported & trusted' way to do this kind of migration.
