数据库管理员详细介绍
数据库管理员
每个oracle数据库至少应该有一名数据库管理员(dba).
1）职责：
a.安装和升级oracle数据库
b.建库、表空间、表、视图、索引...
c.制定并实时备份与恢复计划
d.数据库权限管理，调优，故障排除
e.对于高级dba，要求能参与项目开发，会编写sql语句、存储过程、触发器、规则、约束、包；
2）管理数据库的用户主要是sys和system
区别：
①存储的数据的重要性不同
sys：所有oracle的数据字典的基表和视图都存放在sys用户中，这些基表和视图对与oracle的运行是至关重要的，由数据库自己维护，任何用户都不能手动更改；sys用户拥有dba：数据库管理员角色，sysdba：系统管理员，sysoper：系统操作员角色或权限，是oracle权限最高的用户。
system：用于存放一级的内部数据，如oracle的一些特性或工具的管理信息；system用户拥有dba，sysdba角色或系统权限。
system如果正常登录，它其实就是一个普通的dba用户，但是如果以as sysdba登录，其结果实际上它是作为sys用户登录的，从登录信息里面可以看出来。
（dba:数据库管理员角色、sysdba:系统管理员、sysoper:系统操作员）（sysdba>sysoper>dba）
3）sysdba和sysoper权限的区别
①Starup(启动数据库)（两者都有）
②Shuptdown(关闭数据库)（两者都有）
③alter database open/mount/backup（两者都有）
④改变字符集（sysoper没有）
⑤create database(创建数据库)（sysoper没有）
⑥drop database(删除数据库)（sysoper没有）
⑦create spfile（两者都有）
⑧alter database archivelog(归档日志)（两者都有）
⑨alter database recover(恢复数据库)（sysoper只能完全恢复，不能执行不完全恢复）
⑩restricted session(会话限制)（两者都有）
⑪可以让用户作为sys用户连接（sysoper可以进行一些基本操作，但是不能查看用户数据）
⑫登录之后用户是sys（sysoper登录之后用户是public）
4）dba权限的用户
dba用户是指具有dba角色的数据库用户，特权用户可以执行启动实例，关闭实例等特殊操作，而dba用户只有在启动数据库后才能执行各种管理工作。
（意味着dba没有Starup(启动数据库)、Shutdown(关闭数据库)的权限）
5）管理初始化参数
初始化参数用于设置实例或是数据库的特征(每个初始化参数都有默认值)。

每个oracle数据库至少应该有一名数据库管理员(dba).
1）职责：
a.安装和升级oracle数据库
b.建库、表空间、表、视图、索引...
c.制定并实时备份与恢复计划
d.数据库权限管理，调优，故障排除
e.对于高级dba，要求能参与项目开发，会编写sql语句、存储过程、触发器、规则、约束、包；
2）管理数据库的用户主要是sys和system
区别：
①存储的数据的重要性不同
sys：所有oracle的数据字典的基表和视图都存放在sys用户中，这些基表和视图对与oracle的运行是至关重要的，由数据库自己维护，任何用户都不能手动更改；sys用户拥有dba：数据库管理员角色，sysdba：系统管理员，sysoper：系统操作员角色或权限，是oracle权限最高的用户。
system：用于存放一级的内部数据，如oracle的一些特性或工具的管理信息；system用户拥有dba，sysdba角色或系统权限。
②权限的不同
sys用户必须以as sysdba或as sysoper形式登录，不能以normal(标准)方式登录数据库。system如果正常登录，它其实就是一个普通的dba用户，但是如果以as sysdba登录，其结果实际上它是作为sys用户登录的，从登录信息里面可以看出来。
（dba:数据库管理员角色、sysdba:系统管理员、sysoper:系统操作员）（sysdba>sysoper>dba）
3）sysdba和sysoper权限的区别

②Shuptdown(关闭数据库)（两者都有）
