У меня есть сервер базы данных, на котором запущено Oracle 18.2 XE с приложением Apex 19.2, обслуживаемым через ORDS. ORDS находится за IIS 10.
Приложение работает правильно, но время от времени оно не работает, и я получаю следующее сообщение об ошибке ... и мне приходится перезапускать сервер, чтобы он заработал.
Есть ли у кого-нибудь идеи, как это решить, пожалуйста? Спасибо.
