其中:Security ON: Local OS Authentication 此條提示信息表明監聽處於Local OS Authentication認證模式.
Oracle 10g版本以及之后的版本中推出了監聽的本地操作系統認證安全特性.若監聽程序是在當前用戶下啟動的，
則當前用戶具有管理監聽的所有權利，其他用戶對監聽的管理將受到限制 因為數據庫是11.2.0.1而且使用了oracle restart特性且用戶為grid.注冊了listener服務且只對默認端口1521有效.
之前是1532所以oracle restart不會自動重啟監聽.由於將端口修改成了1521所以oracle restart自動重啟了listener [grid@node2 ~]$ srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): node2,node1
這個是不用管的
問題描述二
oracle sqlplus / as sysdba 連接不上去
oracle 死活連接不上去，實例是啟動的完好無損，原因是權限不對，
問題解析
跟據自己的實例分析所有權限：
[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
具體截圖：
權限賦予完整后問題解決，具體權限根據實際情況分析，這里是RAC集群問題
