Почему ошибка ORA-12514: TNS:listener does not currently know of service requested in connect descriptor?

Здравствуйте.

На 3-х виртуальных машинах в локальной сети
192.168.0.21
192.168.0.22
192.168.0.23
проинсталлированы 3 экземпляра Oracle

1 и 2 работает инстансы,
3-й при подключении клиента возвращает ошибку

An error was encountered performing the requested operation:
Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
Vendor code 12514

Как решить проблему с 3-м эксземпляром?

Answer 1

[Smithson]

Вот тут пишут, что надо исправить SERVICE_NAME в tnsnames.ora

Comments

[Николай Бараненко]

могут ли в одной подсети быть несколько экземпляров с одинаковым Global Database Name? и влияет ли наличие Container Database также одинаково именованное?

[Smithson]

Николай Бараненко: А шут его знает :) Не пробовал.

Answer 2

[Николай Бараненко]

В общем в одной подсети инстансы oracle с одинаковыми service name и портами жить могут.

в listener.ora добавляем информацию о новом подключении по IP и меняем порт

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 2001))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2001))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.22)(PORT = 2001))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2001))
    )	
  )

В tnsnames.ora заносим информацию о новых экземплярах

SERVER01_DBORACLE_LOCAL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.22)(PORT = 2001))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dboracle)
    )
  )  
  
SERVER01_DBORACLE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 2001))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = dboracle)
    )
  )    
ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2001))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

LISTENER_DBORACLE =
  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 2001))

После перезапускаем службы листенера и самой БД.

Проверяем командой
lsnrctl status

lsnrctl reload – переинициализировать листенер иногда помагает, когда инстанс не инициализовался листенером
