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