Have you looked at MTTR to see if it meets the needs of the recovery scenarios at your site?

I have redo log sized to 800MB in a one of our databases. I am considering to double its size, as
the application generates too much redo, due to bad application code. Even for one column change,
the rest of the row gets updated with the same values.

I have heard of no issues with large redo log files. I just need to make sure I have enough log
groups and enough archived dest space to not affect archiving of redo logs..

This is on AIX 5.2 with Oracle 9.2.0.4
