请教linux中的oracle安装问题

Nicholaszh

我安装的是红帽子13(Red Hat Enterprise Linux ES 3),安装Oracle的时候先装了
j2sdk-1_4_2-nb-3_5_1-bin-linux.bin,Linux系统核心参数、oracle帐户的环境变量、oracle用户帐户及安装目录都已经设定好，但执行./runInstaller之后提示下列错误信息:

[oracle@localhost oracle]$ /mnt/windows/oracle/Disk1/runInstaller
[oracle@localhost oracle]$ Initializing Java Virtual Machine from   /tmp/OraInstall2004-07-05_05-42-14PM/jre/bin/java. Please wait...
Error occurred during initialization of VM
Unable to load native library: /tmp/OraInstall2004-07-05_05-42-14PM/jre/lib/i386/libjava.so: symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

[oracle@localhost oracle]$     
   
我估计j2sdk-1_4_2-nb-3_5_1-bin-linux.bin中没带java虚拟机，安装界面启动不了，是否还要安装java虚拟机才行?
另外，我想花点money去考DBA,各位牛人是否可以给点意见(少花点银子多花点功夫小弟很愿意接受)
