最近因为一个测试环境需要oracle 9i，我在Oracle linux 4.8上安装，竟然遇到几个问题记录下：
1.运行runInstaller提示如下错误

[oracle@xifenfei Disk1]$ ./runInstaller
[oracle@xifenfei Disk1]$ Initializing Java Virtual Machine from /tmp/OraInstall2012-03-04_09-32-16PM/jre/bin/java. Please wait...
Error occurred during initialization of VM
Unable to load native library: /tmp/OraInstall2012-03-04_09-32-16PM/jre/lib/i386/libjava.so:
symbol __libc_wait, version GLIBC_2.0 not defined in file libc.so.6 with link time reference

解决方法：打上p3006854_9204_LINUX.zip补丁

[root@xifenfei tmp]$ unzip p3006854_9204_LINUX.zip
Archive:  p3006854_9204_LINUX.zip
   creating: 3006854/
  inflating: 3006854/rhel3_pre_install.sh
  inflating: 3006854/README.txt
[root@xifenfei 3006854]# cd 3006854
[root@xifenfei 3006854]# chmod +x rhel3_pre_install.sh
[root@xifenfei 3006854]# ./rhel3_pre_install.sh

2.在Linking Oracle9i到63%时入到如下错误

解决办法：在/usr/bin目录下有gcc 和 gcc32两个文件，执行 mv gcc gcc296 和 mv gcc32 gcc,完成之后，retry安装界面

[root@xifenfei tmp]# cd /usr/bin
[root@xifenfei bin]# ls gcc*
gcc  gcc32  gcc4
[root@xifenfei bin]# mv gcc gcc296
[root@xifenfei bin]# mv gcc32 gcc

3.执行netca/dbca报如下错误

[oracle@xifenfei Disk1]$ dbca
/u01/oracle/jre/1.1.8/bin/../lib/i686/green_threads/libzip.so: symbol errno,
version GLIBC_2.0 not defined in file libc.so.6 with link time reference (libzip.so)
Unable to initialize threads: cannot find class java/lang/Thread
Could not create Java VM
[oracle@xifenfei Disk1]$ netca
/u01/oracle/jre/1.1.8/bin/../lib/i686/native_threads/libzip.so: symbol errno,
version GLIBC_2.0 not defined in file libc.so.6 with link time reference (libzip.so)
Unable to initialize threads: cannot find class java/lang/Thread
Could not create Java VM

解决办法:在环境变量中加上LD_ASSUME_KERNEL=2.4.1

vi .bash_profile --加上下面语句
export LD_ASSUME_KERNEL=2.4.1
source ~/.bash_profile
