升级Oracle Rac 11.2.0.4 到 11.2.0.4.1
1、当前数据库环境：
双节点Oracle linux 5.4 RAC
Grid software 11.2.0.4
Oracle software 11.2.0.4
OPatch Version 11.2.0.3.4
2、OPatch下载
下载11.2.0.4.1 Patch:17478514
p17478514_112040_Linux-x86-64.zip
根据该psu readme ：
OPatch Utility
You must use the OPatch utility version 11.2.0.3.5 or later to apply this patch. Oracle recommends that you use the latest released OPatch version for 11.2, which is available for download from My Oracle Support patch 6880880 by selecting the 11.2.0.0.0 release.
由于OPatch Version 11.2.0.3.4，所以我们需要更新OPatch version，下载OPatch ：补丁程序6880880: OPatch patch of version 11.2.0.3.6 for Oracle software releases 11.2.0.x
p6880880_112000_Linux-x86-64.zip
3、更新OPatch version/OCM configuration
将p6880880_112000_Linux-x86-64.zip解压到各个节点DB home 和 GI home
节点1,2上分别用grid和oracle用户执行
mv $ORACLE_HOME/OPatch/ $ORACLE_HOME/OPatch.bak
节点1,2上分别用grid和oracle用户执行
unzip /software/p6880880_112000_Linux-x86-64.zip -d $ORACLE_HOME/
节点1,2上分别用grid和oracle用户执行
--执行如下命令在当前目录下创建文件 ocm.rsp
cd $ORACLE_HOME/OPatch/
$ORACLE_HOME/OPatch/ocm/bin/emocmrsp
验证OPatch版本更新
$ORACLE_HOME/OPatch/opatch version
OPatch Version: 11.2.0.3.6
OPatch succeeded.
4、Patch Conflict Detection and Resolution
解压文件：
unzip p17478514_112040_Linux-x86-64.zip
cd /software/17478514/
冲突检测：
节点1,2上分别用grid和oracle用户执行
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./
5、Instructions for Patching a Grid Infrastructure (GI) Home
root用户执行:（注意权限问题，，grid用户安装补丁该补丁由grid解压，oracle类似）
