It's easier enough. Just use the DBMS_RANDOM package supplied by Oracle.
SQL> desc rndm
Name                                      Null?    Type
COL1                                               NUMBER
COL2                                               VARCHAR2(10)
COL3                                               DATE
SQL> BEGIN
  2     DBMS_RANDOM.initialize(12348765);
  3     FOR i IN 1..4 LOOP
  4        INSERT INTO rndm VALUES (dbms_random.value
  5                                 , dbms_random.string('A', 10)
  6                                 , sysdate + dbms_random.value(1,1000));
  7     END LOOP;
  8  END;
  9  /
PL/SQL procedure successfully completed.
SQL> SELECT * FROM rndm;
      COL1 COL2       COL3
.028766128 pUFMxywBzC 14-JAN-07

.454116997 EHCEZKPORm 14-FEB-05

SQL> Note that the published API seems to have changed in 9.2 (if not earlier), with the apparent sole purpose of DBMS_RANDOM being the generation of random numbers. However, as you can see, the old methods still work. Not sure what Oracle are up to.
