Any performance issues for hot backups ??

I am looking into the possibilities Oracle can give me to do 'hot backups'. From a developers point of view I don't have to do anything, except require that the database is started in the ARCHIVELOG mode. (at least that is what I read so far, if I am wrong in this assumption, please let me know).

I am pretty sure that when I write the above as a conclusion I will immediately be getting responses (from within my company) saying that this solution is not workable because of performance issues. Therefor I am asking this group for 'field' experiences. Are there any reports or does anyone have experience that indicates that the performance of the Oracle database degrades (significantly) or hardly affects it when running in archivelog mode ?

Regards,

Bas
