系统环境：
操作系统：AIX 5.3.8
Oracle: Oracle 10gR2
案例分析：
在构建RAC时，安装完CRS需要做安装后的校验，在执行校验工具cluvfy时出现以下错误：

修改可执行脚本权限：
[root@aix230:/u01/soft/Disk1/cluvfy]#chmod 777 runcluvfy.sh
仍然失败，看来不是权限的问题：
[root@aix230:/u01/soft/Disk1/cluvfy]#./runcluvfy.sh
The unzip of archive file ./jrepack.zip failed
查看可执行脚本的内容，发现秘密

DIRNAME=/bin/dirname

查看本机unzip可执行文件位置：
[root@aix230:/u01/soft/Disk1/cluvfy]#which unzip
/u01/crs_1/bin/unzip
竟然不在"/usr/bin"下
拷贝unzip到"/usr/bin"下
[root@aix230:/u01/soft/Disk1/cluvfy]#cp /u01/crs_1/bin/unzip /usr/bin
[root@aix230:/u01/soft/Disk1/cluvfy]#which unzip
/usr/bin/unzip然后执行：
[root@aix230:/u01/soft/Disk1/cluvfy]#/u01/soft/Disk1/cluvfy/runcluvfy.sh -h
USAGE:
cluvfy [ -help ]
cluvfy stage { -list | -help }
cluvfy stage {-pre|-post} [-verbose]
cluvfy comp { -list | -help }
cluvfy comp [-verbose]@至此，问题得以解决！！！
