oracle-11g-r2 – 尝试将Windows SQL * Plus客户端连接到Oracle 11g Linux服务器时出现错误ORA-12560
作者：互联网
我在我的mac上在Centos VM上安装了11g.我已经完成所有工作并在服务器上运行.我已经包含了以下命令,我在cenos上运行.
$lsnrctl状态

我的tnsnames.ora文件如下：
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = hayer)(PORT = 1522))
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = hayer)(PORT = 1522))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
(SID = orcl)
)
)

在Centos服务器上我也可以使用sqlplus登录.我将Windows上的tnsnames.ora更改为与server相同.我在Windows主机文件中添加了oracle主机信息,我可以在端口1522上ping oracle主机和telnet主机.
我已禁用服务iptables,因此centos上不存在任何类型的防火墙.
但我仍然在Windows客户端上出现以下错误：

解决方法:
在Windows客户端上,您需要指定TNS别名@ORCL,否则它会假定您正在尝试连接到Windows客户端上运行的本地数据库,而该客户端没有.此外,系统通常不使用sysdba,甚至不确定是否有意义.使用SYS作为sysdba和普通系统.

如果您的Windows客户端上没有设置tnsnames.ora,您仍然可以通过EZCONNECT字符串@“hayer：1522 / orcl”连接,而不是设置tnsnames(是的,需要引号).
Enter user-name: system@"hayer:1522/orcl"
