All the databases that I have worked on or been responsible for, have been 24x7. Here are some suggestions:

Know the requirements of your environment in regards to UPTIME. Have it documented. The best practice that works well is Service Level Agreements, if there is none in place, implement them. There is a world of cost differences between systems that can be down for 2 hours to those which can't be down at all.
In high availability databases, a Hardware cluster configuiration is highly recommended for 2 purposes: (A) Fast recovery and (B) Software upgrades (both APP and DB).
If you do not have a Test server, buy one!
Make sure that everyone (network Admins, DBAs, System Admins, etc.) has a way to communicate with one another. I suggest Cell phones as apposed to pagers.
Kiss your weekends and Holidays good bye!

If you have any specific questions, please feel free to contact me at satarnag_at_hotmail.com

Satar
