记录centos6.8安装Oracle10.2.0.1过程中的错误解决

[root@hadoop01 database]# ./runInstaller
./runInstaller: /opt/database/install/.oui: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
原因：没有安装ld-linux.so.2
[root@hadoop01 database]# yum install -y ld-linux.so.2
继续安装[root@hadoop01 database]# ./runInstaller

原因：开发系统版本不对
1. [root@hadoop01 database]# ./runInstaller --ignoreSysPrereqs   这样是忽略系统版本，后面还是会报错建议按下面的修改：

2. vi /etc/redhat-release 将redhat 5.1 该为 redhat 4 . 装完后改回即可

The user is root. Oracle Universal Installer cannot continue installation if the user is root.
: No such file or directory

原因：不能用root用户安装：创建dba group和user oracle

Exception java.lang.UnsatisfiedLinkError: /tmp/OraInstall2016-10-12_08-59-12AM/jre/1.4.2/lib/i386/libawt.so: libXp.so.6: cannot open shared object file: No such file or directory occurred..
原因是：缺少支持打印的图形化动态链接库libXp.so.6
yum install -y libXp.so.6
yum install -y libXt.so.6
yum install -y libXtst.so.6

Warning: Cannot convert string "-b&h-lucida-medium-r-normal-sans-*-140-*-*-p-*-iso8859-1" to type FontStruct
原因：好像是字符集的问题，而且不能启动安装页面，于是./runInstaller

执行netca或dbca时, "UnsatisfiedLinkError exception loading native library: njni10"错误解决
安装对应32位glibc
重新安装：
ORA-27125:unable to create shared memory segment
安装被中断。

解决方法如下：
#id oracle

uid=500(oracle) gid=501(oinstall)groups=501(oinstall),502(dba),503(asmadmin),504(oper)

[root@rac2 ~]# more/proc/sys/vm/hugetlb_shm_group
0

下面用root执行下面的命令，将dba组添加到系统内核中：
# echo 502 >/proc/sys/vm/hugetlb_shm_group

--这里的502 是上面的id 命令查看出来的。
# more /proc/sys/vm/hugetlb_shm_group
502
然后重新DBCA，成功建立实例！
