Oracle12c只能用127.0.0.1地址連線，不能遠端訪問問題
1.該問題需要在listener中新增區域網ip地址的監聽
2.手動修改tnsnames.ora檔案
仿照原有：
PDBORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PDBORCL)
)
)
LISTENER_ORCL =(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
本地配置新增新的配置如下：
LISTENER_ORCL2 =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.4.30.44)(PORT = 1521))
ORCL2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.4.30.44)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
PDBORCL2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.4.30.44)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PDBORCL)
)
)
3.重啟服務及監聽
