Create a new database on the Sun workstation using the same database name and tablespace/datafile names. Create your schema owner. Do an export on the original database, and import into the new database.

Export parfile

inctype=complete
file=name_of_dump_file
log=name_of_log_file

Import parfile
userid=system/password@dbname
full=y
