一、系统要求：
最低内存256M，建议512M，硬盘空间5G（AS3自定义安装，操作系统大概是2个G，oracle9204大概是2.5G），如果是把oracle安装文件复制到硬盘上再安装则需要7G；交换分区为内存倍，如果内存为1G或更大时为内存相同大小查看物理内存：# grep MemTotal /proc/meminfo查看交换分区大小：# /sbin/swapon ?s
二、安装前的准备：
oracle9204安装软件（一共三张盘，可到http://www.oracle.com下载），oracle9204补丁：p3006854_9204_LINUX.zip，p3119415_9204_LINUX.zip，p2617419_210_GENERIC.zip；在安装oracle9204前必须打p3006854_9204_LINUX.zip补丁，p3119415_9204_LINUX.zip和p2617419_210_GENERIC.zip是agent的补丁，如果不打这两个补丁agent就没法正常启动。因为是直接安装9204的版本，所以p3095277_9204_LINUX.zip的补丁就不用打了。
三、检查以下软件包是否已安装：
compat-db-4.0.14-5.i386.rpm compat-gcc-7.3-2.96.122.i386.rpm compat-gcc-c++-7.3-2.96.122.i386.rpm compat-libstdc++-7.3-2.96.122.i386.rpm compat-libstdc++-devel-7.3-2.96.122.i386.rpm openmotif21-2.1.30-8.i386.rpm setarch-1.3-1.i386.rpm tcl-8.3.5-92.i386.rpm检查软件包# rpm ?qa | grep compat compat-db-4.0.14-5.i386 compat-gcc-7.3-2.96.122.i386 compat-gcc-c++-7.3-2.96.122.i386 compat-libstdc++-7.3-2.96.122.i386 compat-libstdc++-devel-7.3-2.96.122.i386 # rpm ?qa | grep openmotif21 openmotif21-2.1.30-8.i386
# rpm ?qa | grep setarch setarch-1.3-1.i386
#rpm ?qa | grep tcl tcl-8.3.5-92.i386在AS3的第三张及其它光盘上有安装软件包，例：# rpm ?ihv compat- compat-gcc-7.3-2.96.122.i386.rpm注意：软件包的安装是有先后次序。
四、设置系统参数
1.更改gcc、g++版本mv /usr/bin/gcc /usr/bin/gcc323 ln -s /usr/bin/gcc296 /usr/bin/gcc mv /usr/bin/g++ /usr/bin/g++323 ln -s /usr/bin/g++296 /usr/bin/g++注意：如果gcc296，g++296没安装，请先安装该软件包2.设置内核参数修改/etc/sysctl.conf、/etc/security/limits.conf两个文件#vi /etc/sysctl.conf添加以下参数kernel.shmmax = 2147483648 （以字节为单位，物理内存*1024*1024*2，为物理内存的2倍）
kernel.shmmni=4096 kernel.shmall=2097152 kernel.sem=250 32000 100 128 fs.file-max=65536 net.ipv4.ip_local_port_range=1024 65000保存退出执行以下命令使配置马上生效# sysctl -p #vi /etc/security/limits.conf添加以下参数oracle hard nofile 65536 oracle soft nofile 65536 oracle hard nproc 16384 oracle soft nproc 16384
五、创建运行oracle数据
系统管理用户及设置其的环境变量1.创建组和用户# groupadd oinstall # groupadd dba # useradd -g oinstall -G dba oracle # passwd oracle
2.设置用户环境变量以oracle打开新的终端窗口或 在root 终端窗口上# su ? oracle $ vi $HOME/bash_profile添加export LD_ASSUME_KERNEL=2.4.1 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/9.2.0 export ORACLE_SID=myora export ORACLE_TERM=xterm # export TNS_ADMIN= Set if sqlnet.ora， tnsnames.ora， etc. are not in $ORACLE_HOME/network/admin――这是设置参数文件所在位置，例如：tnsnames.ora，sqlnet.ora， spfilexxx.ora export NLS_LANG=“Simplified Chinese_china”。ZHS16GBK export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data export LD_LIBRARY_PATH=$ LD_LIBRARY_PATH ORACLE_HOME/lib：/lib：/usr/lib：/usr/local/lib export PATH=$PATHORACLE_HOME/bin $ source $HOME/.bash_profile――让设置马上生效或重新登录系统3.创建oracle安装目录以root用户身份打开另一个终端窗口# mkdir -p /u01/app/oracle # chown ?R oracle.oinstall /u01/app/oracle # chmod ?R 775 /u01/app/oracle # mkdir /var/opt/oracle # chown ?R oracle.dba /var/opt/oracle # chmod ?R 775 /var/opt/oracle
六、安装oracle数据库系统（当前用户是root）
1.解包# unzip ship_9204_linux_disk1.cpio.gz # unzip ship_9204_linux_disk2.cpio.gz # unzip ship_9204_linux_disk3.cpio.gz # cpio ?idmv
进入Disk1目录$ ./runInstaller数据库用户组为 “dba”
安装时一定要记得选择支持多语言核心字符集（AL32UTF，选择安装过程中自动创建数据安装过程中会提示用root 执行/tmp/orainstRoot.sh 、/u01/app/oracle/product/9.2.0/root.sh这两个脚本安装时agent会启动失败，略过继续下一步…。
打agent补丁以修正agent不能正常启动的bug （还是oracle 用户身份）
先停止oracle的一些后台服务$ sqlplus “sys/as sysdba” ――提示输入oracle sys用户的密码，直接回车就可以SQL>；shutdown immediate SQL>；lsnrctl stop $ unzip p3238244_9204_LINUX.zip $ cp p2617419_210_GENERIC.zip /tmp $ cd /tmp $ unzip p2617419_210_GENERIC.zip $ export PATH=$PATH：/tmp/Opatch $ export PATH=$PATH：/sbin $ cd ……/……/ 3238244 $ opatch apply $ cd $ORACLE_HOME/network/lib $ make ?f ins_oemagent.mk install $ sqlplus “sys/as sysdba” ――提示输入密码回车略过SQL>；startup SQL>；exit $ lsnrctl start运行 $ agentctl start 测试agent代理能否正常工作$ agentctl start如果数据库不能正常启动请执行$ dbca把旧库删除再创建一个新库七、安装好后打/u01/app/oracle/product/9.2.0/network/admin/sqlnet.ora文件添加SQLNET.AUTHENTICATION_SERVICE=（NTS）
只要在本地主机上运行sqlplus以数据库系统管理员登录都必须输入密码才可进入oracle数据库系统。
Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool 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.
