Oracle 11g RAC 应用补丁简明版

之前总结过《Oracle 11.2.0.4 RAC安装最新PSU补丁》，

这次整理为简明版，忽略一切输出的显示，引入一些官方的说明，增加OJVM PSU的补丁应用。

环境：RHEL6.5 + Oracle 11.2.0.4 RAC（4 nodes）

本次需求：应用最新的PSU，OJVM PSU补丁。

目前最新发布（2016-07-19）的PSU,OJVM PSU补丁文件分别为：

p23274134_112040_Linux-x86-64.zip

p23177551_112040_Linux-x86-64.zip

• 1.检查OPatch版本
• 2.解压补丁文件
• 3.确认已停止OEM
• 4.本次PSU补丁说明
• 5.手动应用补丁
• 6.数据库应用PSU
• 7.应用OJVM PSU
• 8.应用补丁结果

1.检查OPatch版本

需要跟踪对应补丁的README说明，确定当前环境的OPatch版本符合要求，如果不符合要求，需要下载符合要求的OPatch版本。

1.1 查询OPatch版本

$ORACLE_HOME/OPatch/opatch version

1.2 替换为新版本OPatch

备份原来的OPatch，解压/tmp下的新版本OPatch到$ORACLE_HOME下，检查OPatch的版本：

mv $ORACLE_HOME/OPatch $ORACLE_HOME/OPatch_bak && cd /tmp && unzip p6880880_112000_Linux-x86-64.zip -d $ORACLE_HOME
$ORACLE_HOME/OPatch/opatch version

2.解压补丁文件

$ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME
解压补丁文件：赋权确定解压的目录/usr2有对应权限，然后解压补丁文件

root:
chown oracle:oinstall /usr2 && chmod 775 /usr2 && mv /tmp/p23274134_112040_Linux-x86-64.zip /usr2/
grid:
cd /usr2 && unzip p23274134_112040_Linux-x86-64.zip

3.确认已停止OEM

Stop EM Agent Processes Prior to Patching and Prior to Rolling Back the Patch

查看em运行状态：
$ORACLE_HOME/bin/emctl status dbconsole
如果状态是运行，则需要关闭：
$ORACLE_HOME/bin/emctl stop dbconsole

一般是在Oracle用户登录1节点 停止em。

4.本次PSU补丁说明

23054359
DB PSU 11.2.0.4.160719 (INCLUDES CPUJUL2016)
Both DB Homes and Grid Home

23054319
OCW PSU 11.2.0.4.160719
Both DB Homes and Grid Home

22502505
ACFS PSU 11.2.0.4.160419
Only Grid Home

5.手动应用补丁

Manual Steps for Apply/Rollback Patch
See My Oracle Support Document 1641136.1 for cases where opatch auto cannot be used.
文档第5部分
5 Manual Steps for Apply/Rollback Patch

5.1 停止CRS

--1.Stop the CRS managed resources running from DB homes. If this is a GI Home environment, as the database home owner execute:
`$ <ORACLE_HOME>/bin/srvctl stop home -o <ORACLE_HOME> -s <status file location> -n <node name>`

$ORACLE_HOME/bin/srvctl stop home -o $ORACLE_HOME -s /tmp/stophome.log  -n xxx01

实际这一步没成功，也没看出对应用补丁什么影响.

5.2 运行rootcrs.pl

--2.Run the pre root script. If this is a GI Home, as the root user execute:
`# <GI_HOME>/crs/install/rootcrs.pl -unlock`

停止节点1的服务
su - root
$GRID_HOME/crs/install/rootcrs.pl -unlock

5.3 应用CRS补丁

--3.Apply the CRS patch using. As the GI home owner execute:
$ <GI_HOME>/OPatch/opatch napply -oh <GI_HOME> -local <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>
As the GI home owner execute:
$ <GI_HOME>/OPatch/opatch napply -oh <GI_HOME> -local <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<ACFS Components_number>
As the GI home owner execute:
$ <GI_HOME>/OPatch/opatch apply -oh <GI_HOME> -local <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<DB_PSU_number>

grid用户登录，打对应补丁：

su - grid
$GRID_HOME/OPatch/opatch napply -oh $GRID_HOME -local /usr2/23274134/23054319
$GRID_HOME/OPatch/opatch napply -oh $GRID_HOME -local /usr2/23274134/22502505
$GRID_HOME/OPatch/opatch apply -oh $GRID_HOME -local /usr2/23274134/23054359

5.4 补丁安装前执行脚本

--4.Run the pre script for DB component of the patch. As the database home owner execute:
$ <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>/custom/server/<OCW Components_number>/custom/scripts/prepatch.sh -dbhome <ORACLE_HOME>

Oracle用户登录，补丁安装前检查：

su - oracle
$ /usr2/23274134/23054319/custom/server/23054319/custom/scripts/prepatch.sh -dbhome $ORACLE_HOME

5.5 应用DB补丁

--5.Apply the DB patch. As the database home owner execute:
$ <ORACLE_HOME>/OPatch/opatch napply -oh <ORACLE_HOME> -local <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>/custom/server/<OCW Components_number>
$ <ORACLE_HOME>/OPatch/opatch apply -oh <ORACLE_HOME> -local <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<DB_PSU_number>

oracle用户登录，打对应补丁：

$ORACLE_HOME/OPatch/opatch napply -oh $ORACLE_HOME -local /usr2/23274134/23054319/custom/server/23054319
$ORACLE_HOME/OPatch/opatch apply -oh $ORACLE_HOME -local /usr2/23274134/23054359

5.6 补丁安装后执行脚本

--6.Run the post script for DB component of the patch. As the database home owner execute:
$ <UNZIPPED_PATCH_LOCATION>/<GI_PSU_number>/<OCW Components_number>/custom/server/<OCW Components_number>/custom/scripts/postpatch.sh -dbhome <ORACLE_HOME>

oracle用户登录，补丁修复完确定：

$ /usr2/23274134/23054319/custom/server/23054319/custom/scripts/postpatch.sh -dbhome $ORACLE_HOME

5.7 root用户执行脚本

--7.Run the post script. As the root user execute:
# <GI_HOME>/rdbms/install/rootadd_rdbms.sh
If this is a GI Home, as the root user execute:
# <GI_HOME>/crs/install/rootcrs.pl -patch
If this is an Oracle Restart Home, as the root user execute:
# <GI_HOME>/crs/install/roothas.pl -patch

root用户登录，执行脚本：

su - root
# $GRID_HOME/rdbms/install/rootadd_rdbms.sh
# $GRID_HOME/crs/install/rootcrs.pl -patch

5.8 可能的报错

--8.If the message, "A system reboot is recommended before using ACFS??? is shown, then a reboot must be issued before continuing. Failure to do so will result in running with an unpatched ACFS\ADVM\OKS driver.

5.9 呼应5.1步骤，这里也没做

--9.Start the CRS managed resources that were earlier running from DB homes. If this is a GI Home environment, as the database home owner execute:
$ <ORACLE_HOME>/bin/srvctl start home -o <ORACLE_HOME> -s <status file location> -n <node name>
If this is an Oracle Restart Home environment, as the database home owner execute:
$ <ORACLE_HOME>/bin/srvctl start home -o <ORACLE_HOME> -s <status file location>

6.数据库应用PSU

6.1 关闭数据库然后应用PSU

srvctl stop database -d lrnop

6.2 根据下面文档的内容操作

2.5.2 Loading Modified SQL Files into the Database

The following steps load modified SQL files into the database. For an Oracle RAC environment, perform these steps on only one node.

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
The catbundle.sql execution is reflected in the dba_registry_history view by a row associated with bundle series PSU.

For information about the catbundle.sql script, see My Oracle Support Document 605795.1 Introduction to Oracle Database catbundle.sql.

If the OJVM PSU was applied for a previous GI PSU patch, you may see invalid Java classes after execution of the catbundle.sql script in the previous step. If this is the case, run utlrp.sql to re-validate these Java classes.

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> @utlrp.sql
Check the following log files in $ORACLE_BASE/cfgtoollogs/catbundle for any errors:

catbundle_PSU_<database SID>_APPLY_<TIMESTAMP>.log
catbundle_PSU_<database SID>_GENERATE_<TIMESTAMP>.log
where TIMESTAMP is of the form YYYYMMMDD_HH_MM_SS. If there are errors, see Section 3, "Known Issues".

This patch now includes the OJVM Mitigation patch (Patch:19721304). If an OJVM PSU is installed or planned to be installed, no further actions are necessary. Otherwise, the workaround of using the OJVM Mitigation patch can be activated. As SYSDBA do the following from the admin directory:

SQL > @dbmsjdev.sql
SQL > exec dbms_java_dev.disable
For more information on the OJVM mitigation patch, see Document 1929745.1 Oracle Recommended Patches -- "Oracle JavaVM Component Database PSU" (OJVM PSU) Patches.

2.5.3 Upgrade Oracle Recovery Manager Catalog

If you are using the Oracle Recovery Manager, the catalog needs to be upgraded. Enter the following command to upgrade it:

$ rman catalog username/password@alias
RMAN> UPGRADE CATALOG;

7.应用OJVM PSU

7.1 打OJVM PSU

p23177551_112040_Linux-x86-64.zip

7.2 应用OJVM PSU

su - oracle
cp /tmp/p23177551_112040_Linux-x86-64.zip /usr2 && cd /usr2 && unzip p23177551_112040_Linux-x86-64.zip

$ cd <PATCH_TOP_DIR>/23177551
$ opatch prereq CheckConflictAgainstOHWithDetail -ph ./

cd /usr2/23177551 && opatch apply

7.3 数据库应用OJVM PSU

--1.For an Oracle RAC environment, reload the packages on one of the nodes using the following commands. Make sure no other instance of the database is up on the remote nodes.

cd $ORACLE_HOME/sqlpatch/23177551
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> alter system set cluster_database=false scope=spfile;
SQL> SHUTDOWN
SQL> STARTUP UPGRADE
SQL> @postinstall.sql
SQL> alter system set cluster_database=true scope=spfile;
SQL> SHUTDOWN
SQL> STARTUP
--2.After installing the SQL portion of the patch, some packages could become INVALID. This will get recompiled upon access or you can run utlrp.sql to get them back into a VALID state.

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> @utlrp.sql

8.应用补丁结果

最终验证应用补丁的结果：
各节点的$GRID_HOME,$ORACLE_HOME,都可以使用opatch lspatches查看补丁应用的情况：

[root@db02 tmp]# su - grid
[grid@db02 ~]$ $ORACLE_HOME/OPatch/opatch lspatches
23054359;Database Patch Set Update : 11.2.0.4.160719 (23054359)

23054319;OCW Patch Set Update : 11.2.0.4.160719 (23054319)

OPatch succeeded.
[grid@db02 ~]$ exit
logout
