10.安装并创建数据库
在root用户下，先将光盘中的oracle数据库软件拷到根目录下，然后再执行： unzip 10201_database_linux32.zip
mv database/* /home/oracle
su – oracle（切换到oracle用户下）
du –sh ./database/ 【查看文件的大，因为文件正在传送】
cd database（当数据库从根目录都拷到oracle用户的家目录下时，再进入该目录）
ls
进行系统检测：
./runInstaller（请以KDE视窗模式下进入.否则无法执行runInstaller）
如果出现以下问题：
[oracle@oracle ~]$ ./runInstaller

解决办法：需要切换到root用户执行xhost +
如果还不成功，则在切换到oracle用户，并执行export DISPLAY=0.0
出现以下图形界面，我们选择高级安装模式：
根据提示，此时我们需要切换到两个目录下，分别执行程序：
cd /u01/app/oracle/oraInventory/
./orainstRoot.sh
cd /u01/app/oracle/product/10.2.0/db_1
./root.sh
然后点击ok即可，随即出现安装完成界面，点击退出即可。
以上会出现是否同意的信息，使管点击I aggress即可。
到此为止，安装已经全部结束，数据库也创建了。(有人可能会在安装数据库的时候没有创建数据库，这时就可以用dbca创建，注意：dbca是创建数据库帮手，可以帮你创建数据库)
如果上图中出现Java的错误提示信息，则需要编辑/u01/app/oracle/product/10.2.0/db_1/sysman/config，在此文件中加入
agentTZRegin=Asia/Shanghai
11.下面是对数据库的管理：
