oracle是11g，我在服务器上部署web程序直接连本机数据库，
tnsnames.ora文件
# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.1.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
LISTENERBOB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.90)(PORT = 1521))
)
(CONNECT_DATA =
(Service_Name = orcl)
(SID = orcl)
)
)
listener.ora文件内容
# listener.ora Network Configuration File: D:\app\Administrator\product\11.1.0\db_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.
LISTENERIT =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.90)(PORT = 1521))
)
SID_LIST_LISTENERIT =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = Oracle8)
(ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1)
(SID_NAME = ORCL)
)
)
一直报 “ORA-12504: TNS: 监听程序在 CONNECT_DATA 中未获得 SERVICE_NAME” 错误，以前曾经可以过，好久没动，居然不行了，于是我把监听和net服务全部重新配置了，
------解决方案--------------------
LISTENERBOB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.90)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
------解决方案--------------------
- SQL code
listener.ora文件内容改成如下:SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = ORCL) (ORACLE_HOME = D:\app\Administrator\product\11.1.0\db_1) (SID_NAME = ORCL) ) )LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) ) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.90)(PORT = 1521)) ) )--tnsnames.ora内容:LISTENERBOB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.90)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ORCL) ) )
------解决方案--------------------
先在system用户下查一下你的数据库实例名是否为“orcl”？：
select value$ from sys.props$ where name='GLOBAL_DB_NAME';
------解决方案--------------------
show parameter service_names
另外看看INIT.ORA文件里有service_names这一项吗？它的值是否等于ORCL
当然前提必须如楼上所说的你要确认名为ORCL的数据库实例存在
