I have backup of database created with this code fragment on SGI IRIX, Oracle 7.2.3:
--------
ALTER TABLESPACE system BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/systdb1.dbf ORACLE_HOME/dbbackup/systdb1.dbf
ALTER TABLESPACE system END BACKUP;

ALTER TABLESPACE rbs BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/rbsdb1.dbf $ORACLE_HOME/dbbackup/rbsdb1.dbf
ALTER TABLESPACE rbs END BACKUP;

ALTER TABLESPACE temp BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/tempdb1.dbf $ORACLE_HOME/dbbackup/tempdb1.dbf
ALTER TABLESPACE temp END BACKUP;

ALTER TABLESPACE tools BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/tooldb1.dbf $ORACLE_HOME/dbbackup/tooldb1.dbf
ALTER TABLESPACE tools END BACKUP;

ALTER TABLESPACE users BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/usrdb1.dbf $ORACLE_HOME/dbbackup/usrdb1.dbf
ALTER TABLESPACE users END BACKUP;

ALTER TABLESPACE adminmtispace BEGIN BACKUP;
host cp $ORACLE_HOME/dbs/adminmtispace.dbf $ORACLE_HOME/dbbackup/adminmtispace.dbf
ALTER TABLESPACE adminmtispace END BACKUP;
...
ALTER DATABASE BACKUP CONTROLFILE TO '$ORACLE_HOME/dbbackup/ctrldb1.ctl';

host cp $ORACLE_HOME/dbs/*.ora $ORACLE_HOME/dbbackup

host cp $ORACLE_HOME/network/admin/*.ora $ORACLE_HOME/dbbackup

How can I restore this files on another IRIX, Oracle computer??
