11.2.0.3 补丁集在美国时间9月23日发布了，关于11.2.0.3 发布的更多信息可以参考<Oracle 11gR2发布11.2.0.3 Patchset补丁集-又一重量级更新>一文。
这里我们来快速浏览由11.2.0.2 RAC升级到11.2.0.3的过程：
在正式升级GI/CRS之前需要先打上”Patch 12539000: 11203:ASM UPGRADE FAILED ON FIRST NODE WITH ORA-03113″
我们仅需要针对GI/CRS打上补丁，无需在RDBMS/DB上实施。该Patch可以滚动升级Rolling upgrade, 简易的实施流程如下：
1. 在所有节点上安装最新的opatch工具，该步骤不需要停止任何服务
[root@vrh1 ~]# su - grid
[grid@vrh1 ~]$ cd $CRS_HOME
[grid@vrh1 grid]$ mv OPatch OPatch_old
[grid@vrh1 grid]$ unzip /tmp/p6880880_112000_Linux-x86-64.zip -d $CRS_HOME
[grid@vrh1 grid]$ opatch
Invoking OPatch 11.2.0.1.3
Oracle Interim Patch Installer version 11.2.0.1.3

2. 解压之前下载的 p12539000_112020_Linux-x86-64.zip 的补丁包，！！注意不要解压在/tmp目录下！！
[grid@vrh1 ~]$ mkdir /g01/patch
[grid@vrh1 ~]$ cd /g01/patch
[grid@vrh1 patch]$ unzip /tmp/p12539000_112020_Linux-x86-64.zip

1.解压软件包，第三个zip包为grid软件
[grid@vrh1 tmp]$ unzip p10404530_112030_Linux-x86-64_3of7.zip
2. 以GI拥有者用户启动GI/CRS的OUI安装界面，并选择Out of Place的安装目录

4. 确认GI/CRS成功升级到11.2.0.3 :
[grid@vrh2 ~]$ crsctl query crs activeversion Oracle Clusterware active version on the cluster is [11.2.0.3.0]
升级11.2.0.2 RDBMS/DB到 11.2.0.3
1. 解压RDBMS/DB 相关的第1-2个 zip包：
[root@vrh1 ~]# su - oracle [oracle@vrh1 tmp]$ mkdir /s01/patch [oracle@vrh1 tmp]$ cd /s01/patch [oracle@vrh1 patch]$ unzip /tmp/p10404530_112030_Linux-x86-64_1of7.zip [oracle@vrh1 patch]$ unzip /tmp/p10404530_112030_Linux-x86-64_2of7.zip
2.
因为11.2.0.2的Patchset以后都是out of place的，所以我们可以不用像在11gr2以前那样必须在原有安装低版本软件的基础上才能升级软件，而可以选择在别的位置完全新安装。
注意该步骤不需要停止数据库实例，可以在前期工作中完成。
以DB/RDBMS数据库软件的拥有者身份(oracle用户)启动方才解压目录下的oui安装界面:
su – oracle
(oracle)$ unset ORACLE_HOME ORACLE_BASE ORACLE_SID
(oracle)$ export DISPLAY=:0
(oracle)$ cd $PATCHHOME
(oracle)$ ./runInstaller
依次在所有节点上执行root.sh脚本
/s01/orabase/product/11.2.0/dbhome_3/root.sh
3. 使用DBUA静默模式升级RAC数据库的数据字典
su - oracle
[oracle@vrh1 ~]$ export ORACLE_HOME=/s01/orabase/product/11.2.0/dbhome_3
/* 这里的SID指定数据库名 */
[oracle@vrh1 ~]$ $ORACLE_HOME/bin/dbua -silent -sid VPROD

4.更新所有节点上.bash_profile 中的ORACLE_HOME等变量
5.执行过DBUA升级工具的节点上的orapw$SID密码文件已被更新，将该文件传播到其他节点上
6.确认数据字典升级成功，并重启所有实例

11.2.0.3上optimizer_features_enable造成的一些变化
我们知道几乎每个Patchset都会引入Oracle Optimizer优化器的一些微妙变化，升级到11.2.0.3后默认的optimizer_features_enable(OFE)为11.2.0.3，我们来了解一下这与11.2.0.2时有哪些区别：
