Я пытаюсь подключиться к Oracle 10.2.0 из NetBeans, используя следующую строку подключения:
jdbc:oracle:thin:@localhost:1521:XE
Самая странная часть - все работает нормально, пока одна из перезагрузок. Я все время начал получать эти ошибки TNS-12505; посмотрите последние записи в моем listener.log:

Первые три записи - мои попытки подключения из NetBeans. В-четвертых, подключение через SQL * Plus работало просто отлично.
Вот содержимое моего listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\oraclexe\app\oracle\product\10.2.0\server)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
(ADDRESS = (PROTOCOL = TCP)(HOST = Brodyaga-PC)(PORT = 1521))
)
)
DEFAULT_SERVICE_LISTENER = (XE)
И tnsnames.ora:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Brodyaga-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
И вывод из служб < lsnrctl

Обе службы Oracle запускаются, и SQL * Plus подключается отлично.
Есть ли способ обхода этой ошибки?
