Cold backup before upgrade using xcopy on Windows
Hello, we are running Oracle Database Standard Edition 11.2.0.3.0 on Windows Server 2008 R2. In a previous thread about upgrading from 11.2.0.3.0 to 11.2.0.4.0, it was suggested that I perform a cold backup before installing the new home and upgrading the database. So after some searching I found several examples of using Windows xcopy to perform the cold backup. Below is the commands I have come up with to do this. Here is my questions:
1) Have I included all of the files I need to back up?
2) Do I have the xcopy switches correct to insure everything is copied?
3) I read in another post that the database upgrade will also back up the data. Do I really need to do that portion twice?
