其中:Security ON: Local OS Authentication 此条提示信息表明监听处于Local OS Authentication认证模式.
Oracle 10g版本以及之后的版本中推出了监听的本地操作系统认证安全特性.若监听程序是在当前用户下启动的，
则当前用户具有管理监听的所有权利，其他用户对监听的管理将受到限制 因为数据库是11.2.0.1而且使用了oracle restart特性且用户为grid.注册了listener服务且只对默认端口1521有效.
之前是1532所以oracle restart不会自动重启监听.由于将端口修改成了1521所以oracle restart自动重启了listener [grid@node2 ~]$ srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): node2,node1
这个是不用管的
问题描述二
oracle sqlplus / as sysdba 连接不上去
oracle 死活连接不上去，实例是启动的完好无损，原因是权限不对，
问题解析
跟据自己的实例分析所有权限：
[root@node2 bin]# cd /u01/app/grid/11.2.0/crs/bin/ [root@node2 bin]# chown grid.oinstall oracle [root@node2 bin]# chmod +s oracle [root@node2 bin]# chown root.oinstall oradism [root@node2 bin]# chmod +s oradism [root@node2 bin]# chown root.oinstall jssu [root@node2 bin]# chmod +s jssu [root@node2 bin]# chown root.oinstall extjob [root@node2 bin]# chmod +s extjob [root@node2 bin]# cd /u01/app/oracle/product/11.2.0/db_1/bin/ [oracle@node2 bin]$ chown root.oinstall extjob [oracle@node2 bin]$ chmod +s extjob [root@node2 bin]# chown root.oinstall jssu [root@node2 bin]# chown root.oinstall nmb [root@node2 bin]# chown root.oinstall nmhs [root@node2 bin]# chown root.oinstall nmo [root@node2 bin]# chmod +s nmb [root@node2 bin]# chmod +s nmhs [root@node2 bin]# chmod +s nmo [root@node2 bin]# chmod +s jssu [root@node2 bin]# chown oracle.asmadmin oracle [root@node2 bin]# chmod +s oracle [root@node2 bin]# chown root.oinstall oradism [root@node2 bin]# chmod +s oradism

权限赋予完整后问题解决，具体权限根据实际情况分析，这里是RAC集群问题
