服務器端安裝完後,

D:\app\Oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN 下

1. listener.ora 下紅色部分是新增 . orcl177是實例名稱. Host :172.30.70.177 這裏是服務器IP

# listener.ora Network Configuration File: D:\app\Oracle\product\11.2.0\dbhome_1\network\admin\listener.ora

)
)

ADR_BASE_LISTENER = D:\app\Oracle

2.tnsnames.ora 下  HOST 改成IP 172.30.70.177

# tnsnames.ora Network Configuration File: D:\app\Oracle\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL177 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.70.177)(PORT = 1521))

(SERVER = DEDICATED)
(SERVICE_NAME = orcl177)
)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =

客戶端:tnsnames.ora 下新增

Orcl_177 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.30.70.177)(PORT = 1521))
)
(CONNECT_DATA =

)
)

改完後 PL/SQL Develop 能夠連上
