Investigate/improve user impact of Oracle error

[jonespm]

We frequently get an error
"ORA-00942: table or view does not exist"

This is expected behavior while the database is reloading and usually happens when someone tries to access the application around midnight. In April we've gotten about 20 of these errors as the usage of Student Explorer picks up.

• What does the user currently see when they get this.
  • I'm guessing it's just a generic error message, hopefully it's not an actual error message
• Should/can we provide a better message for this case
  • I think for this we could say "The student explorer data is currently unavailable for a daily load, please try back again a little later"
