TNS-12545: Connect failed because target host or object does not exist

TNS-12545: Connect failed because target host or object does not exist
Cause: The address specified is not valid, or the program being connected to does not exist.
Action: Ensure the ADDRESS parameters have been entered correctly; the most likely incorrect parameter is the node name. Ensure that the executable for the server exists (perhaps "oracle" is missing.) If the protocol is TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric IP address and try again.

TNS-12545：连接失败，因为目标主机或对象不存在,
.原因：指定的地址无效，或正在连接的程序不存在。,
.操作：确保ADDRESS参数输入正确; 最可能不正确的参数是节点名称。确保服务器的可执行文件存在（可能缺少“oracle”。）如果协议是TCP / IP，请编辑TNSNAMES.ORA文件以将主机名更改为数字IP地址，然后重试。,
