Oracle 11g RAC 自动应用PSU补丁简明版

环境：Oracle RAC(GI 11.2.0.4 + DB 11.2.0.4)

本文应用补丁信息：

Patch 23615403 - Combo of OJVM Component 11.2.0.4.160719 DB PSU + GI PSU 11.2.0.4.160719 (Jul2016)

本文主要演示使用opatch auto自动应用补丁的过程。

• 1.更新OPatch版本
• 2.配置ocm.rsp文件
• 3.使用opatch auto应用补丁
• 4.数据库修改

1.更新OPatch版本

在所有节点的GI HOME和DB HOME下，都更新为符合应用补丁需求的OPatch版本。
将之前OPatch备份，解压新版本的OPatch到$ORACLE_HOME目录下，最后检查OPatch版本。

--更新OPatch版本 @all nodes including GI HOME and DB HOME
mv OPatch OPatch_bak
unzip p6880880_112000_Linux-x86-64.zip -d $ORACLE_HOME
$ORACLE_HOME/OPatch/opatch version

2.配置ocm.rsp文件

在各个节点的grid用户下OPatch下，配置ocm.rsp文件。

--生成ocm响应文件 @all nodes
[grid@jyrac2 ~]$ cd /opt/app/11.2.0/grid/OPatch/ocm/bin/
[grid@jyrac2 bin]$ ls
emocmrsp
[grid@jyrac2 bin]$ ./emocmrsp

[grid@jyrac2 bin]$ ls
emocmrsp  ocm.rsp
[grid@jyrac2 bin]$ pwd
/opt/app/11.2.0/grid/OPatch/ocm/bin

3.使用opatch auto应用补丁

使用opatch auto应用补丁，具体需要参照补丁包中附带的readme来操作。
根据readme中描述，对于GI HOME和DB HOME都不共享的情况下，使用root用户在每个节点执行opatch auto的具体命令即可实现自动应用补丁。

Case 1: GI Home and the Database Homes that are not shared and ACFS file system is not configured.

As root user, execute the following command on each node of the cluster:

opatch auto UNZIPPED_PATCH_LOCATION/23615403 -ocmrf ocm response file

先确认补丁包的解压目录（各节点保持一致，方便操作）：

[grid@jyrac2 bin]$ cd /opt/app/media/
[grid@jyrac2 media]$ ls
23615403  p23615403_112040_Linux-x86-64.zip  PatchSearch.xml

然后使用opatch auto应用补丁，

--opatch auto @all nodes

[root@jyrac1 23615403]# /opt/app/11.2.0/grid/OPatch/opatch auto /opt/app/media/23615403 -ocmrf /opt/app/11.2.0/grid/OPatch/ocm/bin/ocm.rsp

正常应用补丁的输出类似下面这样：

[root@jyrac1 23615403]# /opt/app/11.2.0/grid/OPatch/opatch auto /opt/app/media/23615403 -ocmrf /opt/app/11.2.0/grid/OPatch/ocm/bin/ocm.rsp

This file will show your detected configuration and all the steps that opatchauto attempted to do on your system:

opatch auto succeeded.

这个opatch auto的过程会自动关闭数据库和集群，打完补丁之后自动启动集群和数据库。

同样，第一个节点成功后，在第二个节点应用补丁，输出基本一样，不再演示。

4.数据库修改

最后就是根据readme具体说明，在数据库执行：

cd $ORACLE_HOME/rdbms/admin
sqlplus /nolog
SQL> CONNECT / AS SYSDBA
SQL> STARTUP
SQL> @catbundle.sql psu apply
SQL> QUIT
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
SQL > @dbmsjdev.sql
SQL > exec dbms_java_dev.disable

最后，可以通过 select * from dba_registry_history; 查询一下补丁应用的情况：

SQL> set lines 1000
SQL> select * from dba_registry_history;
ACTION_TIME                                                                 ACTION                         NAMESPACE                      VERSION                                ID BUNDLE_SERIES                  COMMENTS

总的来说，这个opatch auto不出问题的情况下，操作上要比手工打补丁简单的多。

若是想更可控的手工打补丁的话，可以参考之前的文章：《Oracle 11g RAC 应用补丁简明版》
