  28 # This function must be executed for each agent line which has been
  29 # found for the current item. It must deal with the ORA-* error
  30 # messages. It has to skip over the lines which show the SQL statement
  31 # and the SQL error message which comes before the ORA-* message.
  32 #
  33 # The check must completely skip the lines before the ORA-* messages
  34 # and return UNKNOWN on the first found ORA-* message.
  35 # line[0] is the item (db instance)
  36 #
  37 # This function returns a tuple when an ORA-* message has been found.
  38 # It returns False if this line should be skipped by the check.
