If the server already had Windows 2000 running, let' say if we want to upgrade the O/S to Windows Server 2003 with the assumption that all of the database are shutdown. The question is "do we have to reinstall the software and restore the database??? Or we can simply startup the datbase afterward"
how many users are concurrently runing queries/transactions
I have never seen (so far in 4.5 years) a shop which uses windows to run mission critical apps such as CRM, Telecom Billing systems, DWH
Personal experience. It's a bank. Two instances on two-node Win2K cluster, Oracle FailSafe for HA purposes. Each instance has about 500-600 concurent sessions (dedicated server connections). Database size cca 300 GB each. One is transactional system, the other is DWH (kind of). Both are mission critical.
