Oracle 10g RAC 升级（CPU Update）之--升级数据库
系统环境：
操作系统：RedHat EL5
Cluster： Oracle CRS 10.2.0.1.0
Oracle： Oracle 10.2.0.1.0
如图所示：RAC 系统架构
三、升级数据库
数据库的升级需要关闭DataBase，可以采用DBUA以图形的方式升级，也可以采用sqlplus 命令（catupgrd.sql 脚本），本案例采用dbua方式升级。
[root@node2 ~]# srvctl start listener -n node1
[root@node2 ~]# srvctl start listener -n node2
[root@node2 ~]# srvctl start asm -n node1
[root@node2 ~]# srvctl start asm -n node2
[root@node2 ~]# crs_stat -t

升级完成后，在所有node执行以下脚本：
[root@node1 ~]# su - oracle
[oracle@node1 ~]$ /u01/app/oracle/product/10.2.0/db_1/install/changePerm.sh
