1、登陆mos站点下载最新版本的 OPatch补丁，这里以p6880880_102000_Linux-x86-64.zip补丁为例。

https://updates.oracle.com/download/6880880.html

2、上传补丁至服务器，并移动补丁至数据库软件安装目录。

#mv p6880880_102000_Linux-x86-64.zip $ORACLE_HOME

3、切换用户至oracle用户，进入$ORACLE_HOME安装补丁。

[oracle@server ~]$ cd /home/oracle/orahome/

[oracle@server orahome]$ mv OPatch OPatch.old

[oracle@server orahome]$ unzip p6880880_102000_Linux-x86-64.zip

[oracle@server orahome]$ cd OPatch

[oracle@server OPatch]$ ./opatch version

Invoking OPatch 10.2.0.5.1

OPatch Version: 10.2.0.5.1

OPatch succeeded.

[oracle@server OPatch]$

4、可以使用绝对路径来启动 OPatch：

[oracle@server OPatch]$ $ORACLE_HOME/OPatch/opatch version

Invoking OPatch 10.2.0.5.1

OPatch Version: 10.2.0.5.1

OPatch succeeded.

[oracle@server OPatch]$

或者可以把 OPatch 所在的目录加到 PATH 这个环境变量中,之后就可以在任何目录运行 OPatch 命令(opatch )而不需要指定绝对路径

For Korn / Bourne shell:

$ export PATH=$PATH:$ORACLE_HOME/OPatch
