今天升级一个oracle 10g的集群环境到10.2.0.5，网上下载补丁包p8202632_10205_linux-x86-64.zip,解压后安装执行，中途报错：
i/o error cannt reading or opening file in /tmp/...../temp52
网上查资料如下：
根据mos的说明，导致这个错误可能有如下原因：
a) insufficient free space in the temporarydirectory.
b) insufficient access rights on the temporary directory.
c) on oracle 9.2.0.5 to 9.2.0.8, a bug like bug: 5614628.
d) not using a (local) console.
e) corrupted software set.
f) setup of the oracle software in the stage area on disk.
g) wrong unzip utility is used.
h) no execute permission on unzip utility
i)free space => 2tb
j)during ftp from a windows mounted dvd to an unix system (unzipped directories),the new directories in the stage area on unix are all in lowercase.
逐一验证，，最后发现时zip包错误，看来以后下载文件后，最好checksum一下，以防万一
