oracle监听器启动错误-TNS-12546: TNS:permission denied
今天一台数据库服务器登录不上，报TNS-12541: TNS:no listener
到服务器上看下监听器状态
1. oracle@linux-34:~> lsnrctl status

启动下试试

竟然报TNS-12546: TNS:permission denied
查看下 /var/tmp/.oracle、/tmp/.oracle 这两个目录的权限访问。
1. linux-34:~ # ls -lrtd /tmp/.oracle
2. drwxrwxrwx 2 root root 4096 May 9 16:01 /tmp/.oracle
3.
4. linux-34:~ # ls -lrtd /var/tmp/.oracle
5. drwxr-xr-x 2 root root 4096 Oct 14 09:45 /var/tmp/.oracle
原因应该就在这了，/var/tmp/.oracle是755权限，把它修改为777。
chmod -R 777 /var/tmp/.oracle
然后再启动监听试试。
