1，metalink上下载最新的补丁，下载最新的Opatch
2，node3上停CRS等，更新OPatch版本，生成rsp文件，其它主机也会做同样操作
先生成rsp文件
cd /oracle/11.2.0/grid/OPatch/ocm/bin
./emocmrsp
As root user execute:
<GI_HOME>/bin/crsctl start crs
unzip <OPATCH-ZIP> -d <ORACLE_HOME>
<ORACLE_HOME>/OPatch/opatch version
su - grid
unzip /oracle/patchs/p6880880_112000_Linux-x86-64.zip -d /oracle/11.2.0/grid
su - oracle
unzip /oracle/patchs/p6880880_112000_Linux-x86-64.zip -d /oracle/app/oracle/product/11.2.0/db_1
验证补丁是否冲突
opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./12827726
opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir ./12827731
3，node5上手工打补丁
$GRID_HOME/OPatch/opatch napply -oh $GRID_HOME -local /oracle/patchs/12827731
/oracle/11.2.0/grid/OPatch/p12827731/12827731/custom/server/12827731/custom/scripts/prepatch.sh -dbhome $ORACLE_HOME
/oracle/11.2.0/grid/OPatch/p12827731/12827731/custom/server/12827731/custom/scripts/prepatch.sh -dbhome $ORACLE_HOME
$ORACLE_HOME/OPatch/opatch napply -oh $ORACLE_HOME -local /oracle/11.2.0/grid/OPatch/p12827731/12827726
$ORACLE_HOME/OPatch/opatch napply -oh $ORACLE_HOME -local /oracle/11.2.0/grid/OPatch/p12827731/12827731/custom/server/12827731
/oracle/11.2.0/grid/OPatch/p12827731/12827731/custom/server/12827731/custom/scripts/postpatch.sh -dbhome $ORACLE_HOME
其中/oracle/11.2.0/grid/OPatch/p12827731为解压后的地址
4，node4上自动打补丁
su - oracle
[oracle@dtydb4 ~]$ emctl stop dbconsole
As the Grid home owner execute:
$GRID_HOME/OPatch/ocm/bin/emocmrsp
su - grid
unzip /oracle/patchs/p6880880_112000_Linux-x86-64.zip -d /oracle/11.2.0/grid
su - oracle
unzip /oracle/patchs/p6880880_112000_Linux-x86-64.zip -d /oracle/app/oracle/product/11.2.0/db_1
验证补丁版本
$ORACLE_HOME/OPatch/opatch lsinventory
先生成rsp文件
cd /oracle/11.2.0/grid/OPatch/ocm/bin
./emocmrsp
Follow these instructions in this section if the GI home is not shared and none of the Oracle database homes is shared.
As root user execute the following command on each node of the cluster:
/oracle/11.2.0/grid/OPatch/opatch auto /oracle/patchs
/oracle/11.2.0/grid/OPatch/ocm/bin/ocm.rsp
[root@dtydb4 patchs]# /oracle/11.2.0/grid/OPatch/opatch auto /oracle/patchs
Executing /usr/bin/perl /oracle/11.2.0/grid/OPatch/crs/patch112.pl -patchdir /oracle -patchn patchs -paramfile /oracle/11.2.0/grid/crs/install/crsconfig_params

在打补丁的同时，CRS会自动重启
[grid@dtydb4 ~]$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
/oracle/11.2.0/grid/bin/crsctl stop crs
5,node3上自动打补丁，过程同上
6，
For each database instance running on the Oracle home being patched, connect to the database using SQL*Plus. Connect as SYSDBA and run the catbundle.sql script as follows:
cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle.sql psu apply
SQL> QUIT
