　　一、ORACLE的启动和关闭

　　1、在单机环境下要想启动或关闭ORACLE系统必须首先切换到ORACLE用户，如下

　　su - oracle

　　a、启动ORACLE系统

　　oracle>svrmgrl

　　SVRMGR>connect internal

　　SVRMGR>startup

　　SVRMGR>quit

　　b、关闭ORACLE系统

　　oracle>svrmgrl

　　SVRMGR>connect internal

　　SVRMGR>shutdown

　　SVRMGR>quit

　　启动oracle9i数据库命令：

　　$ sqlplus /nolog

　　SQL*Plus: Release 9.2.0.1.0 - Production on Fri Oct 31 13:53:53 2003

　　SQL> connect / as sysdba

　　Connected to an idle instance.

　　SQL> startup^C

　　SQL> startup

　　ORACLE instance started.

　　2、在双机环境下要想启动或关闭ORACLE系统必须首先切换到root用户，如下

　　su － root

　　a、启动ORACLE系统

　　hareg －y oracle

　　b、关闭ORACLE系统

　　hareg －n oracle

　　Oracle数据库有哪几种启动方式

　　说明：

　　有以下几种启动方式：

　　1、startup nomount

　　非安装启动，这种方式启动下可执行：重建控制文件、重建数据库

　　读取init.ora文件，启动instance，即启动SGA和后台进程，这种启动只需要init.ora文件。

　　2、startup mount dbname

　　安装启动，这种方式启动下可执行：

　　数据库日志归档、

　　数据库介质恢复、

　　使数据文件联机或脱机，

　　重新定位数据文件、重做日志文件。

　　执行“nomount”，然后打开控制文件，确认数据文件和联机日志文件的位置，

　　但此时不对数据文件和日志文件进行校验检查。

　　3、startup open dbname

　　先执行“nomount”，然后执行“mount”，再打开包括Redo log文件在内的所有数据库文件，

　　这种方式下可访问数据库中的数据。

　　4、startup，等于以下三个命令

　　startup nomount

　　alter database mount

　　alter database open

　　5、startup restrict

　　约束方式启动

　　这种方式能够启动数据库，但只允许具有一定特权的用户访问

　　非特权用户访问时，会出现以下提示：

　　ERROR：

　　ORA-01035: ORACLE 只允许具有 RESTRICTED SESSION 权限的用户使用

　　6、startup force

　　强制启动方式 bitsCN.com中国网管联盟

　　当不能关闭数据库时，可以用startup force来完成数据库的关闭

　　先关闭数据库，再执行正常启动数据库命令

　　7、startup pfile=参数文件名

　　带初始化参数文件的启动方式

　　先读取参数文件，再按参数文件中的设置启动数据库

　　例：startup pfile=E:Oracleadminoradbpfileinit.ora

　　8、startup EXCLUSIVE

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.
