Dear Gurus,

I have been running my database in noarchive mode and I want to switch to
Archivelog mode. I am running Oracle 7.3.4. I have three groups of redo logs
that are 20MB each. 
My question is what happens to filled online redo logs during a hot/online
backup?? My fear is my database could hang when all redo logs fill up before
my backup completes because it usually takes 2-3 hours (backup) to complete?
and my log switches occur in 15-20 mins.

TIA
Regards
