Oracle Data Guard “Physical Standby Database (Disabled)”

This past week, I was working on a task nobody anywhere ever wants to do: routinely changing passwords. It’s easy enough to do. In Toad for Oracle, right-click the user, Alter, paste new password. That works well until you realize you forgot everywhere you used and need to update that password. In our case, I neglected to stop Data Guard prior to changing the passwords, which caused our production server to be marked as “disabled”.
