How to Import a complete Database in Oracle 9i

I export a backup of my database using the following. How can I overwrite the existing database from a dump file.

set oracle_sid=scrp
exp scrapware/recycle grants=yes owner=scrapware

file=H:\scrp-dump\expSCRp%date:~4,2%%date:~7,2%%date:~-4%%time:~0,2%%time:~3,2%%

time:~6,2%%time:~-2%.dmp

In Oracle a database refers to the files on disk.
An Instance is the memory and server processes.
A Schema is pretty much a user that owns objects.

Based on the question asked:
I assume you exported a schema from one database and want to overwrite that schema in a different database.

If so:
You shouldn't need fromuser and touser if you want to import it into the same schema in a different database.

Binary copy the file from serverA to serverB.  This isn't necessary because the classic exp/imp utilities can run from the client side but it makes things simpler if the file is on the database server.

In the other database, drop and recreate the user then:
imp scrapware/recycle full=Y
file=H:\scrp-dump\expSCRp%date:~4,2%%date:~7,2%%date:~-4%%time:~0,2%%time:~3,2%%
time:~6,2%%time:~-2%.dmp
