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
