当我们需要查看数据库信息时，我们更愿意通过客户端来查看，这样不仅操作方便，而且查看更精准。那么需要远程连接数据库需要在本地修改那些配置呢？以下是我个人的经验，希望大家都指正。
1、在oracle安装目录\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora文件中添加红线以下的配置，可以换行，但不能有间隔。
|
# tnsnames.ora Network Configuration File: E:\oracle\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
YT_PX=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.41.1.21)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = matedb)
)
)

2、监听本地ip有两种方法
（1）在\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora 文件中监听本地ip
|
# listener.ora Network Configuration File: E:\oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = E:\oracle\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:E:\oracle\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = ORCL)
(ORACLE_HOME = E:\oracle\product\11.2.0\dbhome_1)
(SID_NAME = ORCL)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.192.88.220)(PORT = 1521))
)
)
ADR_BASE_LISTENER = E:\oracle
|

（2）在菜单栏找到Net Manager 点击进入
如下图添加新的监听器监听本地ip
