启动监听报错TNS-12547: TNS:lost contact

   今天晚上，遇到一个问题，想从xp的客户端连接到Linux下的ORACLE服务器，首先启动监听器，出现以下错误
  
[oracle@localhost admin]$ lsnrctl start

 首先怀疑是listener.ora日志文件太大了，查看后，排除这种情况
  第二种可能是/etc/hosts写错了  发现这里的IP地址写错了，修正为
   192.168.1.126   localhost.localdomain   localhost
  启动监听器 成功正常

 

   注意：有时候sqlnet.ora是有ip限制的，如果本机的地址没加到那，可能导致这监听器起不来
