Oracle "not connected to ORACLE" fix

oracle_timeout_fix.rb

# If your workers are inactive for a long period of time, they'll lose
# their Oracle connection.
#
# This hack ensures we re-connect whenever a connection is
# lost. Because, really. why not?
#
# Stick this in RAILS_ROOT/config/initializers/connection_fix.rb (or somewhere similar)
#
