Oracle 即使主机名位于tnsnames.ora下，也无法执行tnsping

我无法从目标服务器启动oracle EBS源服务器

VISEBS是源，VISEBST是目标

来源tnsnames.ora：

VISEBS=
    (DESCRIPTION=
            (ADDRESS=(PROTOCOL=tcp)(HOST=xx.xx.xx.149)(PORT=1521))
        (CONNECT_DATA=

            (CONNECT_DATA= (SERVICE_NAME=VISEBST)
                     (INSTANCE_NAME=VISEBST))
        )

目标tnsnames.ora：

VISEBS=
    (DESCRIPTION=
            (ADDRESS=(PROTOCOL=tcp)(HOST=xx.xx.xx.149)(PORT=1521))
        (CONNECT_DATA=

                     (INSTANCE_NAME=VISEBST))
        )

149上的tnsping输出：

两台机器之间的所有ssh连接都工作正常

导致这种情况的问题是什么。

EBS服务器配置为（通过sqlnet.ora中的tcp.u节点）。如果配置了此选项，则只能从受邀节点执行TNS ping。可以通过autconfig变量添加新节点。

您没有显示实际的

tnsping

命令，也没有显示第二个命令的结果（是否也有错误？）。两个

tnsnames.ora

文件中的端口号是否应该不同？它们是否都应该为VISEBST条目设置1523？ssh适合哪里？这些应该通过ssh隧道传输，还是直接访问？对于第二个命令的结果，我得到了TNS-12547:TNS:lost contactyeah，我将端口号更改为1523，然后从源代码开始，但从目标代码开始，现在没有发生@AL
