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

原因：開發系統版本不對
1. [root@hadoop01 database]# ./runInstaller --ignoreSysPrereqs 這樣是忽略系統版本，后面還是會報錯建議按下面的修改：
2. vi /etc/redhat-release 將redhat 5.1 該為 redhat 4 . 裝完后改回即可

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用戶安裝：創建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：缺少支持打印的圖形化動態鏈接庫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：好像是字符集的問題，而且不能啟動安裝頁面，於是./runInstaller
執行netca或dbca時, "UnsatisfiedLinkError exception loading native library: njni10"錯誤解決
安裝對應32位glibc
重新安裝：
ORA-27125:unable to create shared memory segment
安裝被中斷。
解決方法如下：
#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執行下面的命令，將dba組添加到系統內核中：
# echo 502 >/proc/sys/vm/hugetlb_shm_group
--這里的502 是上面的id 命令查看出來的。
# more /proc/sys/vm/hugetlb_shm_group
502
然后重新DBCA，成功建立實例！
