Linux环境下安装oracle遇到的问题小结

在linux环境（RedHat Enterprise Linux5）上安装oracle10g的过程中所出现的问题
1、执行./runInstaller时出现如下错误
Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/OraInstall2010-04-30_02-23-49PM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory

at sun.awt.NativeLibLoader.loadLibraries(Unknown Source)
at sun.awt.DebugHelper.<clinit>(Unknown Source)
at java.awt.Component.<clinit>(Unknown Source)
这是因为缺少安装libXp-1.0.0-8.i386.rpm包所导致的，该包在RedHat Enterprise Linux5系统安装盘第二张安装盘上

2、oracle安装界面乱码
解决方法：
export NLS_LANG=AMERICAN_AMERICA.UTF8
export LC_ALL=C

3、oracle安装检测是出现：
Checking available swap space requirements ...
Expected result: 3024MB
出现这种情况是swap交换分区不够
free -m 查看交换分区只有1983MB，下面的方法将增加swap空间,root下操作
# cd /opt
# dd if=/dev/zero of=/opt/swapfile bs=1M count=2000
# mkswap swapfile
# swapon swapfile
这时候再执行free -m查看swap交换分区的空间变大了
