今天在启动监听时报了以上错误信息，解决办法：

 

经了解，是关于/var/tmp目录下的.oracle文件权限

[oracle@oracle tmp]$ ls -al
total 12
drwxrwxrwt  3 root root 4096 Nov 13 15:32 .
drwxr-xr-x 22 root root 4096 Aug 25  2011 ..
drwxrwxrwt  2 root root 4096 Nov 13 15:30 .oracle (注意这个文件是隐藏文件)
chmod 777 /var/tmp/.oracle

或者是

[oracle@oracle tmp]$  chown -R oracle.dba .oracle/

问题解决

如何以上方法不行，就只有重新创建监听。
