oracle 10g 10.2.0.1升级到10.2.0.4

一、首先升级crs软件：
1，停止数据库、asm、nodeapps
$ srvctl stop database -d hnzz
$ srvctl stop asm -n node1
$ srvctl stop asm -n node2
$ srvctl stop nodeapps -n node1
$ srvctl stop nodeapps -n node2
crs_stat -t 差可能所有资源都是offline状态
2，解压升级包
$su - oracle
$ unzip p6810189_10204_Linux-x86.zip
3,开始执行升级操作
$ cd /tmp/1024/Disk1/
$./runInstaller
开始界面首先选择CRS,中间看看检查结果，确保没错继续
安装过程中执行两个安装脚本
/oracle/app/product/crs/bin/crsctl stop crs
# /oracle/app/product/crs/install/root102.sh
两个都执行完毕后在节点2重复执行操作
二，升级数据库软件
1，停止所有服务
$ srvctl stop database -d hnzz
$ srvctl stop asm -n node1
$ srvctl stop asm -n node2
$ srvctl stop nodeapps -n node1
$ srvctl stop nodeapps -n node2
确认所有节点都offline
2，开始升级数据库软件
$ cd /tmp/1024/Disk1/
$./runInstaller
选择oracle目录
OraDb10g_home1
确保检查全部通过
安装过沉重要执行一个脚本
/oracle/app/product/10.2.0/db_1/root.sh
执行脚本签先备份bin文件（两个节点都执行）
# cd /usr/local/
# cp -rf bin bin.old
执行完成后退出，数据库软件升级完成
三，升级数据库
确保crs在至少一个节点上启动，如果没有启动可以按照下面的方式进行启动
$crs_start -all
$crs_stat -t
 
开始下面的操作
$ sqlplus / as sysdba
