NNL-00018: warning: could not contact default name server

NNL-00018: warning: could not contact default name server
Cause: The control program was unable to contact its default name server during startup. There are a number of possible causes for this error. The control program's SQLNET.ORA file must exist in the correct system-specific location, and must be readable by the control program. The file must contain a names.preferred_servers entry with valid name server addresses. The first server in the preferred-server list must be running, and there must be network connectivity between the control program and that server.
Action: Check to see that all of the above are true. If the control program is still unable to contact its default server, turn on tracing and restart the control program. If the error persists, contact Worldwide Customer Support.

NNL-00018：警告：无法联系默认名称服务器,
.原因：控制程序在启动过程中无法联系其默认名称服务器。这个错误有很多可能的原因。控制程序的SQLNET.ORA文件必须存在于正确的系统特定位置，并且必须由控制程序读取。该文件必须包含具有有效名称服务器地址的names.preferred_servers条目。首选服务器列表中的第一台服务器必须正在运行，控制程序和该服务器之间必须有网络连接。,
.操作：检查以确认以上所有内容。如果控制程序仍然无法联系其默认服务器，请打开跟踪并重新启动控制程序。如果错误仍然存??在，请联系全球客户支持。,
