error when upgrading with database upgrade assistant
I am trying to run Database Upgrade Assistant to upgrade from 22.214.171.124 to 126.96.36.199 on Windows 2000. It was ok until when it is trying to perform the backup. It gave "Could not generate backup of the database". I know I have enough space for the backup destination. This message is so generic, it's useless. Has anyone had similar problem before?
When running Database upgrade assistant, at the beginning it offers to back up the database to be upgraded. So I selected the backup option but it failed. I think as you said, since it's in noarchivelog mode, DBUA probably failed to back it up because cold backup is required.
