HomeDatabaseMysql TutorialRHEL5_x64上安装Oracle 11.2

安装操作系统和补丁包安装操作系统时只安装GNOME桌面yum install gcc gcc-c++ libXp libaio make binutils openmotif setarch co

一:安装操作系统和补丁包
安装操作系统时只安装GNOME桌面
yum install gcc gcc-c++ libXp libaio make binutils openmotif setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel rsh compat-libstdc++-33 elfutils-libelf-devel libaio-devel sysstat unixODBC unixODBC-devel pdksh


二:环境配置
1、创建Oracle安装目录
mkdir -p /u01/oracle/


2、创建用户账号
注意:安装Oracle数据库时必须使用非root用户,root用户被禁止安装
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
useradd -u 500 -g oinstall -G dba,oper,asmadmin -d /u01/oracle oracle
passwd oracle      #设置oracle用户密码
chown -R oracle:oinstall /u01
chmod -R 775 /u01

3、配置用户环境
编辑/etc/profile .bash_profile 文件
export PS1="`/bin/hostname -s`-> "
export ORACLE_SID=wishdb
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export PATH=$ORACLE_HOME/bin:$HOME/bin:/sbin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

编辑/etc/profile文件
if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
        ulimit -p 16384
        ulimit -n 65536
    else
        ulimit -u 16384 -n 65536
    fi
fi

4、配置内核参数
编辑/etc/sysctl.conf文件,添加以下内容.
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
net.ipv4.ipfrag_high_thresh = 524288
net.ipv4.ipfrag_low_thresh = 393216
net.ipv4.tcp_rmem = 4096 524288 16777216
net.ipv4.tcp_wmem = 4096 524288 16777216
net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_sack = 0
net.ipv4.tcp_window_scaling = 1
net.core.optmem_max = 524287
net.core.netdev_max_backlog = 2500
net.ipv4.tcp_mem = 16384 16384 16384
fs.file-max = 6815744
fs.aio-max-nr = 1048576
添加以上内容后必须刷新内核参数:sysctl -p

5、配置登录认证
编辑/etc/pam.d/login文件,添加以下内容,vi /etc/pam.d/login
session required /lib/security/pam_limits.so
session required pam_limits.so

6、配置limits.conf文件
编辑/etc/security/limits.conf文件,添加以下内容,,vi /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

7、开始安装

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.
