There was a problem hiding this comment.
Убрал это условие, т.к. оно было очень странным:
- если "повезло" и источник оказался недоступен в момент проверки триггера, то триггер перейдёт в EXCEPTION, если с момента проверки прошло более
ttlсекунд (это которые "Set NODATA if has no value for ttl seconds"). Плюс к этому здесь генерилось 2NotificationEvent, в случае выполнения условия. - иначе триггер состояние не поменяет + к этому, если источник остаётся не доступным, то триггер вообще не будет проверяться (т.к. если источник недоступен, то триггеры не шедулятся на проверку), т.е. не перейдёт в EXCEPTION
