RHEL6 下安装oracle 10g

这个貌似缺少32位包，你尝试一下安装32位安装包试试
yum install libXt.i686 libXtst.i686 libXp.i686 --setopt=protected_multilib=false
yum 安装 出错 Error: Protected multilib versions:

yum -y install binutils compat-libstdc++-33 compat-libstdc++-33.i686 elfutils-libelf elfutils-libelf-devel GCc gcc-c++ glibc glibc.i686 glibc-common glibc-devel glibc-devel.i686 glibc-headers ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libgcc libgcc.i686 libstdc++ libstdc++.i686 libstdc++-devel make sysstat

以前遇到安装ORACLE成功后，启动过程中遇到ORA-27125错误, 也在博客ORA-27125: unable to create shared memory segment和博客ORA-27125里面记录过，于是按照解决方法做了如下操作:

[root@DB-Server cdrom]# id oracle
uid=502(oracle) gid=502(oinstall) groups=502(oinstall),503(dba)

[root@DB-Server cdrom]# more /proc/sys/vm/hugetlb_shm_group

[root@DB-Server cdrom]# echo 502 >/proc/sys/vm/hugetlb_shm_group

然后在/etc/sysctl.conf 里面添加参数vm.hugetlb_shm_group = 502，就可以在下次启动时不报ORA-27125错误。
