RMAN cold backup vs hot

589266Jan 6 2010 — edited Jan 6 2010

To apply a patch it taking around 3 hours including backing up database.
My question is why should i take cold backup, why not hot backup that can be taken online by placing tablespace into backup mode. Then we can reduce the downtime of backup.

oracle 10.2.4
