求教：Enterprise linux 5上安装oracle 10g出现的问题
本人初学，在Red Hat Enterprise Linux 5上安装oracle10g（10201_database_linux32）时，执行
./runInstaller文件安装时显示如下问题：
-------------------------------------------------------------

在网上查过之后，好多人都说是缺少系统安装包，然后下载了libXp-1.0.0-8.1.el5.i386.rpm安装包，并且开始安装（rpm -ivh '/home/oracle/Desktop/libXp-1.0.0-8.i386.rpm' ），而后又出现了下面的问题：
-----------------------------------------------
warning: /home/oracle/Desktop/libXp-1.0.0-8.i386.rpm: Header V3 DSA signature: NOKEY, key ID 82fd17b2
error: can't create transaction lock on /var/lib/rpm/__db.000
----------------------------------------------------------------------

而后我又在网上查了查：
说：这是由于yum安装了旧版本的GPG keys造成的，解决办法就是

引用
rpm --import /etc/pki/rpm-gpg/RPM*

本人执行这命令之后，又出现了如下问题
----------------------------------------

这些问题可能很基础，可是鉴于本人初学，恳请大家不吝赐教，不胜感激！
