根据patch包中的README.html文件找到静默安装部分：
8.2 Installing the Oracle Database 10g Patch Set Noninteractively
关键是运行如下命令
$ ./runInstaller -silent -responseFile response_file
但安装文件中没有response_file文件的模板，经查找，patch包中的Disk1/response/patchset.rsp为此模板

模板中修改如下选项，其它保持不变：
UNIX_GROUP_NAME=oinstall
－－安装用户组
FROM_LOCATION=/orapatch/Disk1/stage/products.xml
－－patch包的products.xml路径
ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1
ORACLE_HOME_NAME=OraDb10g_home1

确认ORACLE_HOME_NAME选项稍微麻烦点，通过查看/etc/oraInst.loc中inventory_loc值的指向的/ContentsXML/inventory.xml
我的是/u01/app/oracle/oraInventory/ContentsXML/inventory.xml
# less /u01/app/oracle/oraInventory/ContentsXML/inventory.xml
找到
此处的OraDb10g_home1就是上面ORACLE_HOME_NAME选项的值。

下面就开始静默安装（经修改的patchset.rsp文件放在/orapatch/Disk1下）：
注意：此安装需要oracle用户
$ cd /orapatch/Disk1
$ ./runInstaller -silent -responseFile patchset.rsp
此处patchset.rsp不写绝对路径会出如下错误
OUI-10203:The specified response file 'patchset.rsp' is not found. Make sure that the response file specified exists and you have read privileges to this file.

patchset.rsp写了绝对路径后，安装正常进行，速度很快，比图形界面快多了。
$ ./runInstaller -silent -responseFile /orapatch/Disk1/patchset.rsp

至此，使用root用户执行/u01/app/oracle/product/10.2.0/db_1/root.sh，patch安装成功。

接下来就是Manually Upgrading a Release 10.2 Database，还是按README.html做吧！
