[Saurabh Sharma]

hi all, there is an urgent problem that cropped up while i had some problems with oracle 8(version 8.0.4) database and after taking all the necessary backups, full database exports, physical copy of database and net8 folder.. deinstalled it. i then installed oracle 8i (version 8.1.5) and tried to import the exported files after making the same structue(tablespace and users) as there were in previous install. but there is not even a single table import taking place. will u pls help me in where i'm doing wrong. and how i could restore the earlier export files in this new database. here's some info that may help..   earlier version 8.0.4, sid orcl new version 8.1.5  , sid apex no/name of tablespace and users are exactly matching.
