I've worke more than one year in Dev and Test Database , Now they ask me to start production database admin. We have several of them and some of very heavy OLTP type. A little scary even for small changes.

Could somebody tell/refer me to some sort of Articles, URLs, or documents that generally inform me about some DO ... , DON't ... , Never DO ... and this king of things that each individual must follow when she/he apporoach to a critical PROD Database.
