拷贝补丁文件
Oracle11.1.0.7.3的补丁号是9352179，9776431是基于11.1.0.7.3的一个问题补丁，将补丁文件拷贝到/opt/orabak中，目录结构如下：
/opt/orabak/p9352179_111070_Linux-x86-64.zip
/opt/orabak/p9776431_111073_Linux-x86-64.zip
解压缩安装文件，并赋予权限。
【命令】
# cd /opt/orabak
# unzip /opt/orabak/p9352179_111070_Linux-x86-64.zip
# chmod 777 -R /opt/orabak/9352179
# chown oracle:dba -R /opt/orabak/9352179
# unzip /opt/orabak/p9776431_111073_Linux-x86-64.zip
# chmod 777 -R /opt/orabak/9776431
# chown oracle:dba -R /opt/orabak/9776431
升级Opatch
Opatch是安装oracle补丁的工具，在11.1.0.7上打补丁，需要使用版本为11.1.0.8.1的Opatch。默认的Opatch版本是11.1.0.6.2，路径是$ORACLE_HOME/OPatch/opatch，不能用于安装11.1.0.7.3的补丁，因此需要首先升级Opatch到11.1.0.8.1。请将OPatch安装在/opt/orabak下，否则需要替换下面命令中对应的Opatch路径。
检查Opatch的版本号，以oracle用户登陆，切换到Opatch的目录。
【命令】
# export PATH=/opt/orabak/OPatch:$PATH
# cd /opt/orabak/OPatch
# ./opatch version
Invoking OPatch 11.1.0.8.1
OPatch Version: 11.1.0.8.1
OPatch succeeded.
