刚开始使用jar -xvf 进行解压也报错，怀疑jar解压命令有问题。便安装了zip相关包再进行解压还是报错。

jar 解压报错
jar -xvf aix.ppc64_11gR2_database_1of2.zip

unzip 解压报错

通过网上查询相关报错信息，有网友说是上传没有在二进制模式下，也有说上传过程中包有丢失md5值不一致，其中有一条说的系统有限制导致ftp上传不完整。

经检查FTP 上传时提示有限制报错，如下：

查看AIX当前的size数值，该数值表示用户创建的文件大小限制。此定义值（512字节为单位）为该用户可以生成的最大文件的大小。

ulimit -f
2097151

cat /etc/security/limits

default:
fsize = 2097151
core = 2097151
cpu = -1
data = 262144
rss = 65536
stack = 65536
nofiles = 2000

此处输出后段省略

将其fsize更改为-1，使该参数无大小限制。

为使/etc/security/limits文件的更改生效，用户必须注销当前登录会话并重新登录。

重新上传再解压即正常没有报错
