摘要：
配置文件和路径配置文件：tnsnames。ora默认路径：%ORACLE_HOME%etworkadminnsnames。ora，%ORACLE_HOME%通常用于环境变量。我的路径是C:\ProgramFiles（x86）OracleInstantClientnetworkadminnames。或配置文件如下：#tnsnames。oraNetwork配置文件#
配置文件和路径
- 配置文件：
tnsnames.ora - 默认路径:
%ORACLE_HOME% etworkadmin nsnames.ora，%ORACLE_HOME%通常在环境变量中使用。 - 我的路径为：C:Program Files (x86)OracleInstant Client etworkadmin nsnames.or
配置文件如下：
# tnsnames.ora Network Configuration File.
# Generated by Oracle configuration tools.
# Sample:
#DatabaseName =
# (DESCRIPTION =
# (ADDRESS_LIST =
# (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
# )
# (CONNECT_DATA =
# (SERVER = DEDICATED)
# (SERVICE_NAME = ServiceName)
# (INSTANCE_NAME = InstanceName)
# )
# )
# Modify the following content to fit your own needs.
DummyDatabase =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DummyService)
)
)
pcidata_hce =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.10.10)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = devorcl)
)
)
FM_DEV=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.10.223)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = testorcl)
)
)
hceorcl = //数据库名称自定义文中唯一值
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.10.123)(PORT = 1521)) //数据库IP及端口号
(CONNECT_DATA =
(SID =orcl) //实例名
)
)
pdatatest =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.10.182)(PORT = 1521))
(CONNECT_DATA =
(SID =pdatatest)
)
)
162ora =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.20.10.162)(PORT = 1521))
(CONNECT_DATA =
(SID =pdjgorcl)
)
)
这样就可以通过pl/sql developer连接了。
