Redo generation

Whcih would generate more redo?

truncate or delete.

Addtionally, when I try this,

select count(*) from v$archived_log where COMPLETION_TIME=sysdate; I don't get sany result but there are many records in v$archived_log with today's date as completeion date.

Can we check how many redo in MB got generated in last 1 hour?

Regards,
