ORA-16635: network connection failed during transmission

文档解释

ORA-16635: network connection failed during transmission

Cause: The Data Guard broker detected a connection failure to a remote database in the broker configuration. This failure happened in the middle of a transmission session. A transmission session usually requires more than one send operation for sending a large amount of data (for example, the broker configuration file) to the remote database.

Action: In most cases, no user action is required. The Data Guard broker always tries to resend the data. This error will be reported if the problem persists. This error indicates there are some problems with the network connection between broker managed databases. Further network troubleshooting should be done to identify and correct the actual problem.

ORA-16635: network connection failed during transmission是一个网络连接相关的错误，表示在传输过程中，网络连接失败了。

官方解释

常见案例

一般处理方法及步骤

1.检查服务器端和客户端上的网络设置是否正确，确保两者之间的连接是可用的。

2.检查网络上的防火墙或其他安全设备，查看是否限制了两个实例之间的连接。根据实际情况，如果需要，可以删除阻止向目标实例发出连接的规则。

3.确保网络连接处于可用状态，两个实例之间的带宽足够，确保网络正常通信。

4.确保实例之间存在正确的身份验证设置。
