在實際的工作和學習中，很多人都會發現有些Patch沒有setup安裝程序，本文中我們將詳細的介紹如何使用Oracle的opatch工具來進行安裝。

1、下載

Opatch的最新版本可以從Metalink下載，參考 Note:224346.1

(Opatch - Where Can I Find the Latest Version of Opatch?)

2、準備工作

# 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

下載Optach后，上傳到$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

Invoking OPatch 10.2.0.1.6

OUI location : /app/oracle/product/9205/oui

Log file location : /app/oracle/product/9205/cfgtoollogs/opatch/opatch2008-02-20_15-27-23PM.log

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的版本過高。

下載新的Opatch，重新執行opatch lsinventory

[/app/oracle/product/9205/OPatch]$ opatch lsinventory

We recommend you refer to the OPatch documentation under

OPatch/docs for usage reference. We also recommend using

the latest OPatch version. For the latest OPatch version

and other support related issues, please refer to document

Result:

There is no Interim Patch

OPatch succeeded.

3、具體范例及遇到的問題

下面以打補丁5523799為例

[/app/oracle/product/9205/patches/5523799]$opatch apply

報錯：

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.

原因為fuser沒有執行權限,su - root

/usr/sbin#chmod +x fuser

重新命令，打Patch成功

用opatch lsinventory顯示打patch結果

[/app/oracle/product/9205/OPatch]$ opatch lsinventory
