我有两台计算机,计算机A有IP(10.11.11.2),其中包含oracle数据库11g R2,而计算机B有IP(10.11.11.18)。我搜索了很多,并在Tnsnames.ora和listener.ora文件中进行了一些更改但无法连接。但是当我从客户端调整10.11.11.2时,它给了我OK输出。可以从客户端访问该平均数据库,但我无法使用Toad或Sqldeveloper连接数据库。
给出错误: tns目前不知道所要求的服务
我的电脑A(10.11.11.2)tnsname.ora和listener.ora文件粘贴如下:

经过大量研究后我解决了这个问题。我也必须与你分享,以便任何有这个问题的人都可以轻松解决。
Listener.ora文件用于监听请求。如果我们想从另一台计算机访问数据库,我们必须在listener.ora中添加两个条目(一个用于SID,另一个用于机器IP地址)。
计算机A文件(listener.ora和tnsnames.ora)设置如下:
<强> LISTENER.ORA 强>
# listener.ora Network Configuration File: D:\app\Mobilityusr\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 = D:\app\Mobilityusr\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\Mobilityusr\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\app\Mobilityusr\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.11.11.2)(PORT = 1521))
)
)
ADR_BASE_LISTENER = D:\app\Mobilityusr
SID_LIST_LISTENER包含两个条目,首先SID_DESC是默认条目,我们必须添加第二个SID_DESC才能识别orcl SID否则在从其他机器连接数据库时Sqldeveloper或toad或sqlplus将给出以下错误: 错误:sid目前不知道
现在,Listener默认为localhost包含两个条目,我们必须添加包含服务器机器IP的第二个条目。通过此条目服务器上的数据库可以监听包含此IP地址的连接将连接到服务器数据库。否则将无法连接数据库。
注意:您可以使用这些配置,但不要忘记更改IP和oracle_home路径
和tnsnames.ora文件用于定义任何数据库参数(SID,PORT,HOST)的别名。但是,不必将tnsnames.ora更改为连接服务器和客户端,因此我不会修改位于服务器计算机上的tnsnames.ora。
计算机B tnsnames.ora与上述问题相同。 计算机B listener.ora与上述问题相同。
要点: 您只需要更改位于服务器计算机上的listener.ora文件(Oracle_home / network / admin /)。并在SID_LIST_LISTENER中添加两个条目以添加SID详细信息,并在LISTENER中添加第二个条目以添加计算机IP描述。
同时检查环境变量(ORACLE_UNQNAME,ORACLE_SID,ORACLE_HOME,TNS_ADMIN等)
更重要的一点您必须检查Listener服务是否已启动并正在运行 使用这些命令(打开CMD并输入):
** lsnrctl status **
** lsnrctl start **
** lsnrctl stop **
当你更改listener.ora文件时,你必须停止然后启动lsnrctl服务以改变效果。

在SQLDeveloper中,不要指定SID,而是选择Service Name。

我遇到了同样的问题,但是对于Oracle 12C却遇到了很多麻烦。终于使它与几乎类似的解决方案一起工作。
我的数据库服务器位于192.168.1.165上,端口为1526。 还必须在Windows服务器防火墙中打开端口1526。
# listener.ora Network Configuration File: G:\app\db12\product\12.1.0\dbhome_1\network\admin\listener.ora # Generated by Oracle configuration tools. SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = CLRExtProc) (ORACLE_HOME = G:\app\db12\product\12.1.0\dbhome_1) (PROGRAM = extproc) (ENVS = "EXTPROC_DLLS=ONLY:G:\app\db12\product\12.1.0\dbhome_1\bin\oraclr12.dll") ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1526)) (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1526)) ) (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1526)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.165)(PORT = 1526)) ) )
