У меня установлен сервер oracle 11g, и клиенты .Net oracle будут обращаться к базе данных.
До вчерашнего дня я подключался от клиентов, используя эту строку подключения:

User ID=dbcplas;Password=pwd123;Data Source=(DESCRIPTION = (ADDRESS =(PROTOCOL = TCP)(HOST = 172.17.26.7)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl.cplas3.com)))  

До вчерашнего дня я мог использовать Oracle SQL Developer в том же клиенте.
Сегодня утром мы перезапустили сервер для обслуживания. После перезапуска сервера я не могу войти в систему из клиентского приложения .Net или sqldeveloper.
Я могу войти в систему через sql плюс серверной системы.
Кроме того, я не могу войти в систему любым другим способом.
Серверная сторона sql-developer тоже не работает.
Я дал ниже детали с сервера:

Почемуlsnrctl status не показывает статус orcl ??
Я попытался запустить службы orcl. Но его высказывание уже началось ..
В чем может быть проблема ??
