使用Java JDK 1.5或者1.6

Use JDK 6 (Java SE Development Kit 1.6.0_21) or JDK 5  (1.5.0_24) with the JNDI extension with the Oracle Java Database  Connectivity and Oracle Call Interface drivers. However, these are not mandatory  for the database installation. Note that JDK 1.5 is installed with this  release.
以下是对操作系统的配置文件的修改vim /etc/profile

Use a text editor to open the /etc/profile file of the Oracle  Grid Infrastructure installation owner, and find the following line:
ulimit –S –c 0 > /dev/null 2>&1
Change it to the following:
ulimit -S -c unlimited > /dev/null 2>&1

Use a text editor to open /etc/sysctl.conf, and find the  following line:
kernel.core_uses_pid
Confirm that it is set to 1. This setting appends the PID to the generated  core file, which allows multiple core file dumps.
If kernel.core_uses_pid is missing, then add the following  line:
kernel.core_uses_pid = 1

Find the following line:
fs.suid_dumpable
By default, this value is set to 0. Change it to  1.
If fs.suid_dumpable is not in the sysctl.conf file,  then add the following line:
fs.suid_dumpable = 1

Save /etc/sysctl.conf, and use the following command to reload  settings:
# sysctl -p

添加安装的用户组和用户：

[root@oracle ~]# groupadd oinstall
[root@oracle ~]# groupadd dba
[root@oracle ~]# useradd -g oinstall -G dba oracle

继续修改系统参数/etc/sysctl.conf在/etc/security/limits.conf最后添加：# End of file
oracle  soft nproc 2047
oracle  hard nproc 16384
oracle  soft nofile 1024
oracle  hard nofile 65536
oracle  soft stack 10240
oracle  hard stack 20480除了最后一项全部是按照oracle推荐最保守设置。
创建安装目录
这里创建的是/oracle
设置好权限和所有者 chown -R oracle:oinstall /oracle
创建安装目录，，修改oracle 家目录下.bash_profile
在其后添加
# added by qitianwu
TMP=/oracle/tmp
TMPDIR=/oracle/tmp
export TMP TMPDIR
ORACLE_BASE=/oracle/app/oracle
ORACLE_SID=sales
export ORACLE_BASE ORACLE_SID
之后以root身份执行 xhost +
此命令表示，允许任意用户从任意的主机上运行图形命令
以oracle用户登录shell
su – oracle
进入oracle目录  执行./runInstaller
之后图形化配置按照指引一步步完成即可。
