Oracle Unix 9 - slow granting Schema object to User

Question

I have a problem. I can't figure out why granting schema object to users take longer time. here is my codes:
DECLARE
alert_button     NUMBER;
CURSOR Teller_Cur IS SELECT * FROM TELLER_M;
BEGIN
     alert_button := Show_Alert('AlertOK');
     IF alert_button = ALERT_BUTTON1 THEN           
          FOR Teller_Rec IN Teller_Cur LOOP
     Message('Setting table access for ' || Teller_Rec.Teller_ID || ' in progress, please wait....', No_acknowledge);
          IF :DTABLE IS NOT NULL THEN
          -- Granting Schema object to new User
          IF SUBSTR(:DTABLE, 1, 4) = 'TEMP' THEN
          Forms_DDL('GRANT SELECT, INSERT, UPDATE, DELETE ON ' || :DTABLE || ' TO ' || Teller_Rec.Teller_Id || '');
          ELSE     
     IF Teller_Rec.SELECT_ACCESS = 'Y' THEN
     Forms_DDL('GRANT SELECT ON ' || :DTABLE || ' TO ' || Teller_Rec.Teller_Id || '');
     END IF;
IF Teller_Rec.INSERT_ACCESS = 'Y' THEN
Forms_DDL('GRANT INSERT ON ' || :DTABLE || ' TO ' || Teller_Rec.Teller_Id || '');
END IF;     
          IF Teller_Rec.UPDATE_ACCESS = 'Y' THEN
Forms_DDL('GRANT UPDATE ON ' || :DTABLE || ' TO ' || Teller_Rec.Teller_Id || '');
          END IF;      
          IF Teller_Rec.DELETE_ACCESS = 'Y' THEN
Forms_DDL('GRANT DELETE ON ' || :DTABLE || ' TO ' || Teller_Rec.Teller_Id || '');
END IF;      
          END IF;
     -- Creating Synonyms in new User schema
          Forms_DDL('CREATE SYNONYM ' || Teller_Rec.Teller_Id||'.'|| :DTABLE || ' FOR ' || :DTABLE ||'');
ELSE
                         -- for stored procedure:
          Forms_DDL('CREATE SYNONYM ' || Teller_Rec.Teller_Id||'.'|| :DSTOREDP || ' FOR ' || :DSTOREDP ||'');
     Forms_DDL('GRANT EXECUTE ON ' || :DSTOREDP || ' TO ' || Teller_Rec.Teller_Id || '');
END IF;
     END LOOP;     
     Message('Setting table access completed!!!', No_acknowledge);
     END IF;
END;
If i use oracle 8.1.7 locally, it doesn't take than 5 minutes to grant access. But whereas to Oracle 9.0.1 (through network) is taking more than 20 minutes.
If anyone knows, do help me.
Thank you.

The problem is not the difference between the database versions I think; it's the location of the Server.
Take a look what one call of forms_ddl causes network traffic. you have this traffic for each call of forms_ddl. On the Local Server this might not be so much of a problem but with the network between it I this is much slower...
Try to bundle up your statements or even better put the whole stuff in a database procedure to do it via one call. I speeded up creating grants and synonyms from 10 minutes via forms_ddl to 3 minutes using database procedure.
The only limitation is that your messages won't display for each user.
