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
inflated: database/stage/Components/oracle.sysman.console.db/11.2.0.1.0/1/DataFiles/filegroup4.jar java.io.EOFException: Unexpected end of ZLIB input stream at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:241) at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:159) at java.util.zip.ZipInputStream.read(ZipInputStream.java:166) at sun.tools.jar.Main.extractFile(Main.java:753) at sun.tools.jar.Main.extract(Main.java:716) at sun.tools.jar.Main.run(Main.java:226) at sun.tools.jar.Main.main(Main.java:942)
unzip 解压报错 unzip aix.ppc64_11gR2_database_1of2.zip -d oracle/

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： C:\Users\Forrest>ftp 192.168.1.248 连接到 192.168.1.248。 220 localhost FTP server (Version 4.2 Sat Aug 7 19:39:41 CDT 2010) ready. 用户(192.168.1.248:(none)): root 331 Password required for root. 密码: 230-Last login: Wed Dec 31 22:52:13 CST 1969 on /dev/pts/0 from 192.168.1.118 230 User root logged in. ftp> bin 200 Type set to I. ftp> ftp> put D:\迅雷下载\aix.ppc64_11gR2_database_1of2.zip 200 PORT command successful. 150 Opening data connection for aix.ppc64_11gR2_database_1of2.zip. 452 Error writing file: A file cannot be larger than the value set by ulimit. ftp: 发送 1073741824 字节，用时 251.31秒 4272.58千字节/秒。 ftp>
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
