Database installation

本文将介绍Oracle数据库下载及安装等一系列步骤，需要了解的朋友可以参考下

一、Oracle 下载 注意Oracle分成两个文件，下载完后，将两个文件解压到同一目录下即可。路径名称中，最好不要出现中文，也不要出现空格等不规则字符。
官方下地址： http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html以下两网址来源此官方下载页网。 win 32位操作系统下载地址： http://download.oracle.com/otn/nt/oracle11g/112010/win32_11gR2_database_1of2.zip http://download.oracle.com/otn/nt/oracle11g/112010/win32_11gR2_database_2of2.zip
win 64位操作系统下载地址： http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_database_1of2.zip http://download.oracle.com/otn/nt/oracle11g/112010/win64_11gR2_database_2of2.zip 二、Oracle安装 1. 解压缩文件，将两个压缩包一起选择，鼠标右击 -> 解压文件如图

2.两者解压到相同的路径中，如图：

3. 到相应的解压路径上面，找到可执行安装文件【 setup.exe 】双击安装。如图：

4. 安装第一步：配置安全更新，这步可将自己的电子邮件地址填写进去（也可以不填写，只是收到一些没什么用的邮件而已）。取消下面的“我希望通过My Oracle Support接受安全更新(W)”。如图：

5. 安全选项，直接选择默认创建和配置一个数据库(安装完数据库管理软件后，系统会自动创建一个数据库实例)。如图：

6. 系统类，直接选择默认的桌面类就可以了。(若安装到的电脑是，个人笔记本或个人使用的电脑使用此选项) 如图：

7. 典型安装。重要步骤。建议只需要将Oracle基目录更新下，目录路径不要含有中文或其它的特殊字符。全局数据库名可以默认，且口令密码，必须要牢记。密码输入时，有提示警告，不符合Oracel建议时不用管。 (因Oracel建议的密码规则比较麻烦，必须是大写字母加小写字母加数字，而且必须是8位以上。麻烦，可以输入平常自己习惯的短小密码即可) 如图：

8. 若输入的口令短小简单，安装时会提示如下。直接确认Y继续安装就是了。如图：

9. 先决条件检查。安装程序会检查软硬件系统是否满足，安装此Oracle版本的最低要求。直接下一步就OK 了。如图：

10. 概要安装前的一些相关选择配置信息。可以保存成文件或不保存文件直接点完成即可。如图：

11. 安装产品自动进行，不用管。如图：

12. 数据库管理软件文件及dbms文件安装完后，会自动创建安装一个实例数据库默认前面的orcl名称的数据库。如图：

13. 实例数据库创建完成了，系统默认是把所有账户都锁定不可用了(除sys和system账户可用外)，建议点右边的口令管理，将常用的scott账户解锁并输入密码。如图：

14. 解锁scott账户，去掉前面的绿色小勾，输入密码。同样可以输入平常用的短小的密码，不必非得按oracle建议的8位以上大小写加数字，麻烦。呵呵。如图：

15. 同样，密码不符合规则会提示。不用管它，继续Y即可。如图：
16. 安装成功，完成即可。简单吧，呵呵。如图：
三、安装后，进入小测试下 可以通过开始，应用程序中的 "Oracle 11g" -> "应用程序开发" -> "Sql Developer 或Sql Plus" 连接。注意第一次，使用SQL Developer时，会提示指定 java.exe的路径，这里千万别指定自己的java_home了（我就是开始不知道，指定一个JDK6，结束说不兼容。）可以使用Oracel安装路径下面的jdk路径具体是：如图：。

当然若不小心，选择错了。选择了java_home中的高级版本，打开SQL Developer报错后不兼容，也有办法解决。可以在【F:\app\chen\product\11.2.0\dbhome_1\sqldeveloper\sqldeveloper\bin】路径下找到【sqldeveloper.conf】文件后打开找到SetJavaHome 所匹配的值，删除后面的配置内容。保证时会提示，只读文件不可覆盖保存。此时可以另存为到桌面上，然后再回到bin目录中删除掉此文件，再把桌面上的文件复制过去，再打开时，重新选择java.exe。此时选择对就好了。
