如何如何打PSU补丁（11g RAC 升级11.2.0.2.1到最新的PSU11.2.0.2.4）

目的：11g RAC 升级11.2.0.2.1到最新的PSU11.2.0.2.4

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

opatch auto log file location is /oracle/11.2.0/grid/OPatch/crs/../../cfgtoollogs/opatchauto2012-01-13_09-47-25.log

Detected Oracle Clusterware install

Using configuration parameter file: /oracle/11.2.0/grid/crs/install/crsconfig_params

OPatch is bundled with OCM, Enter the absolute OCM response file path:

/oracle/11.2.0/grid/OPatch/ocm/bin/ocm.rsp

patch /oracle/patchs/12827731/custom/server/12827731 apply successful for home /oracle/app/oracle/product/11.2.0/db_1

patch /oracle/patchs/12827726 apply successful for home /oracle/app/oracle/product/11.2.0/db_1

Successfully unlock /oracle/11.2.0/grid

The opatch Applicable check failed for /oracle/11.2.0/grid. The patch is not applicable for /oracle/11.2.0/grid

patch /oracle/patchs/12827731 apply failed for home /oracle/11.2.0/grid

ACFS-9300: ADVM/ACFS distribution files found.

ACFS-9312: Existing ADVM/ACFS installation detected.

ACFS-9314: Removing previous ADVM/ACFS installation.

ACFS-9315: Previous ADVM/ACFS components successfully removed.

ACFS-9307: Installing requested ADVM/ACFS software.

ACFS-9308: Loading installed ADVM/ACFS drivers.

ACFS-9321: Creating udev for ADVM/ACFS.

ACFS-9323: Creating module dependencies - this may take some time.

ACFS-9327: Verifying ADVM/ACFS devices.

ACFS-9309: ADVM/ACFS installation correctness verified.

CRS-4123: Oracle High Availability Services has been started.

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
