前言
还是大家常说的那句：生产环境千万记得备份哈~~~
以下的环境，是我的测试环境，这里就不备份啦~
1. 升级Grid Infrastructure
1.1 升级前准备
1.1.1 软件准备
这个当然不用多说：下载、上传到服务器、解压
1.1.2 新建GI的新HOME
mkdir -p /u01/app/11.2.0.4/grid
chown -R grid:oinstall /u01/app/11.2.0.4
chmod -R 775 /u01/app/11.2.0.4
1.1.3 检查两台Node的名称
[root@RAC01 ~]# cat /etc/hosts
# Do not remove the following line, or variousprograms
# that require network functionality willfail.
127.0.0.1 localhostlocalhost.localdomain localhost
::1 localhost6.localdomain6localhost6
#Eth0 Public
10.0.0.240 RAC01
10.0.0.242 RAC02
#Virtual IP
10.0.0.241 RAC01-VIP
10.0.0.243 RAC02-VIP
#Eth1 Private
172.30.1.1 RAC01-PRIV
172.30.1.2 RAC02-PRIV
#Scan
10.0.0.244 RACSCAN
1.1.4 升级前的CUV检查（建议）
[root@RAC01 app]# su - grid
[grid@RAC01 ~]$ /software/grid/runcluvfy.sh stage -pre crsinst-upgrade -n rac01,rac02 -rolling -src_crshome /u01/app/11.2.0/grid-dest_crshome /u01/app/11.2.0.4/grid -dest_version 11.2.0.4.0
如果检查出错误，请根据提示修复。
1.2 进行升级
需要保证所有节点的GI都正常运行
[grid@RAC01 ~]# su – grid
[grid@RAC01 ~]$ unset ORACLE_HOME
[grid@RAC01 ~]$ unset ORACLE_BASE
[grid@RAC01 ~]$ unset ORACLE_SID
[grid@Oracle-LAB ~]$ cd /software/grid/
[grid@Oracle-LAB grid]$ ./runInstaller
注意：如果在上面一个步骤上点“Next”出现下图错误：
第一：先分别在两个NODE上测试SSH，如：
[grid@rac01 ~]$ sshrac02 date
Fri Jan 10 17:34:55 CST 2014
第二：如果以上不能SSH，那在“SSH Connectivity”中先输入GRID帐号密码，然后再测试，如果SETUP成功，但TEST仍报上图的错误，那可能是因为Node Name大小写引起，需要执行以下命令，命令格式如下：
$ <OLD_GI_HOME>/oui/bin/runInstaller -updateNodelistORACLE_HOME=<OLD_GI_HOME> “CLUSTER_NODES={racnode1,racnode2}” CRS=true
例：
[grid@rac01 grid]$ cd /u01/app/11.2.0/grid/oui/bin/
[grid@rac01 bin]$ ./runInstaller -updateNodelistORACLE_HOME=/u01/app/11.2.0/grid "CLUSTER_NODES=rac01,rac02" CRS=true
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500MB. Actual 5633 MB Passed
The inventory pointer is located at/etc/oraInst.loc
The inventory is located at/u01/app/oraInventory
‘UpdateNodeList‘ was successful.
执行了以上的命令后，重新执行[grid@Oracle-LAB grid]$ ./runInstaller
你会发现Node Name由原来的大写变为小写了，再“Next“就可以了。根据以上提示分别在RAC01、RAC02上执行：
[root@rac01 ~]#/u01/app/11.2.0.4/grid/rootupgrade.sh
[root@rac02 ~]#/u01/app/11.2.0.4/grid/rootupgrade.sh
完成后在当前GRID帐号下运行：crsctlquery has softwareversion查看当前版本信息。
[grid@Oracle-LAB grid]$ crsctl query hassoftwareversion
Oracle High Availability Services version onthe local node is [11.2.0.4.0]
当出现以下报错时，只要能PING通SCAN IP即可忽略。1.1 修改改Grid帐号下的ORACLE_HOME值
[root@rac01/]# gedit /home/grid/.bash_profile
ORACLE_SID=+ASM1
ORACLE_BASE=/u01/app/grid
ORACLE_HOME=/u01/app/11.2.0.4/grid
PATH=$PATH:$ORACLE_HOME/bin
export PATH ORACLE_SID ORACLE_BASE ORACLE_HOME
[root@rac02/]# gedit /home/grid/.bash_profile
ORACLE_SID=+ASM2
ORACLE_BASE=/u01/app/grid
ORACLE_HOME=/u01/app/11.2.0.4/grid
PATH=$PATH:$ORACLE_HOME/bin
export PATH ORACLE_SID ORACLE_BASE ORACLE_HOME
1.2 重启oracle
[root@rac01 /]# cd/u01/app/11.2.0.4/grid/bin
[root@rac01 bin]# ./crsctlstop cluster –all
[root@rac01 bin]# ./crsctlstart cluster -all
完成重启后检查版本：
[root@rac01 bin]# ./crsctlquery crs activeversion
Oracle Clusterware active version on thecluster is [11.2.0.4.0]
2. 升级数据库软件
2.1 升级前准备
2.1.1 软件准备
这个当然不用多说：下载、上传到服务器、解压
注：再次重新强调：生产环境升级前请备份！！
2.1.2 分别在RAC中所有节点上新建DB软件的新HOME
mkdir -p/u01/app/oracle/product/11.2.0.4/dbhome_1
chown -R oracle:oinstall/u01/app/oracle/product/11.2.0.4
chmod -R 775 /u01/app/oracle/product/11.2.0.4
2.1.3 检查Oracle软件版本
[oracle@Oracle-LAB ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on MonJan 6 13:08:12 2014
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release11.2.0.3.0 - 64bit Production
With the Partitioning, Automatic StorageManagement, OLAP, Data Mining
and Real Application Testing options
2.1.4 备份数据库
不再详述。
2.2 进行升级
[oracle@rac01 ~]$ unset ORACLE_BASE
[oracle@ rac01 ~]$ unset ORACLE_HOME
[oracle@ rac01 ~]$ unset ORACLE_SID
[oracle@ rac01 ~]$ cd /software/database/
出现以下错误提示可以忽略，这个主要是因为在DNS中没有对应Node记录引起，不会影响数据库软件的应用与运行。
[root@rac01 /]# /u01/app/oracle/product/11.2.0.4/dbhome_1/root.sh

3. 升级数据库
3.1 升级前检查
进入新目录下执行utlu112i.sql来进行升级前的检查：
[root@Oracle-LAB~]# su - oracle
[oracle@Oracle-LAB~]$ /u01/app/oracle/product/11.2.0.4/dbhome_1/bin/sqlplus / as sysdba

3.2 运行DBUA来升级数据库
以Oracle用户，进入新目录运行DBUA。
[root@rac01/]# su - oracle
[root@Oracle-LAB~]$ cd /u01/app/oracle/product/11.2.0.4/dbhome_1/bin
[oracle@Oracle-LABbin]$ ./dbua
3.3 修改Oracle帐号的ORACLE_HOME
[root@rac01/]# gedit /home/oracle/.bash_profile
ORACLE_SID=RACORCL1 #第二个节点为ORCL2
ORACLE_UNQNAME=RACORCL #如果不配置，EM起不来
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/dbhome_1
PATH=$PATH:$ORACLE_HOME/bin
export PATH ORACLE_SID ORACLE_BASE ORACLE_HOMEORACLE_UNQNAME
[root@rac02 /]# gedit/home/oracle/.bash_profile
ORACLE_SID=ORCL2 #第二个节点为ORCL2
ORACLE_UNQNAME=RACORCL #如果不配置，EM起不来
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/dbhome_1
PATH=$PATH:$ORACLE_HOME/bin
export PATH ORACLE_SID ORACLE_BASE ORACLE_HOMEORACLE_UNQNAME
重启数据库服务：
[root@rac02 /]# /u01/app/11.2.0.4/grid/bin/crsctl stop cluster-all
[root@rac02 /]# /u01/app/11.2.0.4/grid/bin/crsctl start cluster-all
