does it ever complete ?
1) why not you do it in batches ? something like
delete from table where updated_date < date and rownum < 25001;
commit;
then again we can do the same thing until it deletes everything. batch size is just an example to make you understand. you can determine the correct batch size by executing it with 50K or 10K etc and you find it that works quick and should be fine.
2) is there an index for the updated_date column in your table ?
3) after deletion, if you will have only little count of records in that table then why not take only those records to some other table and then truncate this table and then put those records back into original table.
create table bak_table as select * from mytable where <<condition for all the required records>>;
truncate table mytable;
insert into mytable select * from bak_table;
commit;
Thanks
