在实际的工作和学习中，很多人都会发现有些patch没有setup安装程序，本文中我们将详细的介绍如何使用oracle的opatch工具来进行安装。
1、下载
opatch的最新版本可以从metalink下载，参考 note:224346.1
(opatch - where can i find the latest version of opatch?)
2、准备工作
# you must have perl 5.00503 (or later)
# installed under the oracle_home, or elsewhere within the host
# environment. opatch is no longer included in patches as of 9.2.0.2.
# refer to the following link for details on perl and opatch:
# http://metalink.oracle.com/metalink/plsql/ml2_documents.showdocument?p_database_id=not&p_id=189489.1
下载optach后，上传到$oracle_home
[/app/oracle/product/9205/opatch]$chmod 755 *
[/app/oracle/product/9205/opatch]$ opatch version
invoking opatch 10.2.0.1.6
opatch version: 10.2.0.1.6
opatch succeeded.
[/app/oracle/product/9205/opatch]$ opatch lsinventory

lsinventorysession failed:
the oracle home does not meet oui version requirement.
this opatch (version 10.2.0.1.6) detects oui version 10.1.0.5.0 in the home.
it requires oui version 10.2 or above.
opatch failed with error code 73
原因：opatch的版本过高。
下载新的opatch，重新执行opatch lsinventory
[/app/oracle/product/9205/opatch]$ opatch lsinventory
oracle interim patch installer version 1.0.0.0.57

result:
there is no interim patch
opatch succeeded.
3、具体范例及遇到的问题
下面以打补丁5523799为例
[/app/oracle/product/9205/patches/5523799]$opatch apply
报错：
invoking fuser to check for active processes.
invoking fuser on "/app/oracle/product/9205/bin/oracle"
problems when checking for files that are active.
there were problems when checking for active processes on critical files.
the patch tool runs the command "fuser" to check that critical files are not in use. make sure 'fuser' is available and executable on your path
error: opatch failed during pre-reqs check.
原因为fuser没有执行权限,su - root
/usr/sbin#chmod +x fuser
重新命令，打patch成功
用opatch lsinventory显示打patch结果
[/app/oracle/product/9205/opatch]$ opatch lsinventory
oracle interim patch installer version 1.0.0.0.57
