创建目录

/tmp/psu

如果未授权进行会报错，因为是grid用户安装没有权限

在每个节点都运行

chown -R grid:oinstall /tmp/psu 进行授权

[root@rac1 psu]# ll
total 683348
-rw-r--r-- 1 grid oinstall 666719126 Jul 17 18:26 p20996923_112040_Linux-x86-64.zip
-rw-r--r-- 1 grid oinstall  33020933 Aug  1  2014 p6880880_112000_Linux-x86-64.zip

--------------------------------------------------------------------------------

2.升级OPatch工具在所有节点进行

首先查看当前的版本号

（在所有节点运行）

[grid@rac1 ~]$ /u01/app/11.2.0/grid/OPatch/opatch version
OPatch Version: 11.2.0.3.4

OPatch succeeded.
[grid@rac2 ~]$ unzip /tmp/psu/p6880880_112000_Linux-x86-64.zip -d /u01/app/11.2.0/grid/

解压完毕再次检测[grid@rac2 ~]$ /u01/app/11.2.0/grid/OPatch/opatch version
OPatch Version: 11.2.0.3.6
OPatch succeeded.

Oracle

（同样在两个节点运行，检测查看安装）

[oracle@rac1 11.2.0]$ /u01/app/oracle/product/11.2.0/dbhome_1/OPatch/opatch version
OPatch Version: 11.2.0.3.4

OPatch succeeded.

[oracle@rac1 dbhome_1]$ unzip /tmp/psu/p6880880_112000_Linux-x86-64.zip -d /u01/app/oracle/product/11.2.0/dbhome_1

再次检查[oracle@rac1 dbhome_1]$ /u01/app/oracle/product/11.2.0/dbhome_1/OPatch/opatch version 

OPatch Version: 11.2.0.3.6
------------------------------------------------------------------
OPatch succeeded.

先检测当前的版本

[grid@rac2 ~]$ /u01/app/11.2.0/grid/OPatch/opatch lsinventory  -detail -oh /u01/app/11.2.0/grid/

[oracle@rac2 ~]$ /u01/app/oracle/product/11.2.0/dbhome_1/OPatch/opatch lsinventory -detail -oh /u01/app/oracle/product/11.2.0/dbhome_1

--------------------------------------------------------------

3.创建OCM文件

[grid@rac1 ~]$ cd /u01/app/11.2.0/grid/OPatch/ocm/bin/
[grid@rac1 bin]$  ./emocmrsp

[grid@rac1 bin]$ ls -l ocm.rsp
-rw-r--r-- 1 grid oinstall 621 Aug 20 21:38 ocm.rsp

---------------------------------------------------------------------------------

查看是否可以打补丁包

[grid@rac2 bin]$ /u01/app/11.2.0/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /tmp/psu/20996923/
Oracle Interim Patch Installer version 11.2.0.3.6

OPatch apply (所有节点需执行)（无需关闭组件）

[root@rac1 pus]# /u01/app/11.2.0/grid/OPatch/opatch auto /tmp/pus/20996923/ -ocmrf /u01/app/11.2.0/grid/OPatch/ocm/bin/ocm.rsp

我们再次查看下当前版本

 备注：由于官方没有要求打补丁的时候需要关闭DB或CRS，这里可以清晰看出它的执行步骤，
关闭RAC-->补丁RAC -->关闭CRS -->补丁CRS -->启动CRS-->启动RAC、
