PL/SQL developer 连接Oracle数据库

更改tnsnames.ora文件，一般在~\oracle\product\10.2.0\db_2\network\ADMIN目录下
添加如下：
188.10.15.9/ORCLGBK =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 188.10.15.9)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orclgbk)
)
)

(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 数据库IP或数据库主机名)(PORT = 数据库端口号))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = 数据库服务名)
)
)

需要填写数据库IP和数据库端口号和数据库服务名
