一、前言

  欢迎阅读本篇技术文档，本文档将帮助大家顺利完成Oracle Linux 7.9 + ASM安装Oracle 12CR2的过程。在本文档中，您将学到如何准备安装前的环境、如何正确配置ASM磁盘、如何安装Oracle 12CR2，以及如何进行基本配置。希望通过这份文档，能够帮助大家更好地理解Oracle数据库的安装和配置流程，能够更加轻松地进行相关操作。希望本文档能够为您提供有价值的信息，并使您能够成功安装和配置Oracle 12CR2数据库。

二、Oracle ASM简介

  Oracle ASM是用于Oracle数据库文件的卷管理器和文件系统，支持单实例Oracle数据库和Oracle Real Application Clusters（Oracle RAC）配置。Oracle ASM是Oracle推荐的存储管理解决方案，它提供了传统卷管理器、文件系统和裸设备的替代方案。Oracle ASM 使用磁盘组来存储数据文件；Oracle ASM 磁盘组是 Oracle ASM 作为一个单元管理的磁盘集合。在磁盘组中，Oracle ASM 公开 Oracle 数据库文件的文件系统接口。存储在磁盘组中的文件内容均匀分布，以消除热点并在磁盘之间提供统一的性能。性能可与裸设备的性能相媲美。

三、安装前准备

1、环境规划

2、Linux系统参数设置

2.1、hosts文件配置

[root@hellodba ~]# echo "192.168.0.58 hellodba">> /etc/hosts
[root@hellodba ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.58 hellodba

2.2、配置语言环境

[root@hellodba ~]# echo "export LANG=en_US.UTF-8" >> ~/.bash_profile
[root@hellodba ~]# source ~/.bash_profile

2.3、修改 /dev/shm大小

[root@hellodba ~]# df -h /dev/shm
Filesystem Size Used Avail Use% Mounted on
tmpfs 7.8G 0 7.8G 0% /dev/shm
[root@hellodba ~]# echo "none /dev/shm tmpfs defaults,size=16384m 0 0" >> /etc/fstab
[root@hellodba ~]# mount -o remount /dev/shm
[root@hellodba ~]# df -h /dev/shm
Filesystem Size Used Avail Use% Mounted on
tmpfs 16G 0 16G 0% /dev/shm

//关于/dev/shm
在Linux系统中,'/dev/shm'目录是一个特殊的目录,用于实现共享内存,默认是系统内存的50%。它是一个临时文件系统,通常位于RAM(内存)中,而不是硬盘上,并且在系统重启时会被清空。因此,'/dev/shm'目录只适合用于短期存储和进程间通信,不能用于长期存储数据。
'/dev/shm'大小应该大于SGA+PGA的总内存大小,在Linux系统上,如果操作系统'/dev/shm'装载大小对于Oracle系统全局区域(SGA)和程序全局区域(PGA)来说太小,则会导致ORA-00845错误。

2.4、创建数据库用户组和系统用户

[root@hellodba ~]# /usr/sbin/groupadd -g 50001 oinstall
[root@hellodba ~]# /usr/sbin/groupadd -g 50002 dba
[root@hellodba ~]# /usr/sbin/groupadd -g 50003 oper
[root@hellodba ~]# /usr/sbin/groupadd -g 50004 backupdba
[root@hellodba ~]# /usr/sbin/groupadd -g 50005 dgdba
[root@hellodba ~]# /usr/sbin/groupadd -g 50006 kmdba
[root@hellodba ~]# /usr/sbin/groupadd -g 50007 asmdba
[root@hellodba ~]# /usr/sbin/groupadd -g 50008 asmoper
[root@hellodba ~]# /usr/sbin/groupadd -g 50009 asmadmin
[root@hellodba ~]# useradd -u 51001 -g oinstall -G dba,asmdba,asmadmin,backupdba,dgdba,kmdba,oper oracle
[root@hellodba ~]# useradd -u 51002 -g oinstall -G asmadmin,asmdba,asmoper,dba,oper grid
[root@hellodba ~]# echo "oracle" | passwd --stdin oracle
[root@hellodba ~]# echo "oracle" | passwd --stdin grid

2.5、创建数据库安装目录并授权

[root@hellodba ~]# mkdir -p /oracle/app/grid
[root@hellodba ~]# mkdir -p /oracle/app/12.2/grid
[root@hellodba ~]# mkdir -p /oracle/app/oracle
[root@hellodba ~]# mkdir -p /oracle/app/oraInventory
[root@hellodba ~]# mkdir -p /soft
[root@hellodba ~]# chown -R grid:oinstall /oracle
[root@hellodba ~]# chown -R grid:oinstall /oracle/app/oraInventory
[root@hellodba ~]# chown -R oracle:oinstall /oracle/app/oracle
[root@hellodba ~]# chown -R oracle:oinstall /soft
[root@hellodba ~]# chmod -R 775 /oracle
[root@hellodba ~]# chmod -R 775 /soft

2.6、配置YUM源

//挂载光驱
[root@hellodba ~]# mount /dev/cdrom /mnt

//配置YUM源
[root@hellodba ~]# cd /etc/yum.repos.d
[root@hellodba yum.repos.d]# mkdir bak
[root@hellodba yum.repos.d]# mv *.repo bak
[root@hellodba yum.repos.d]# echo "[EL]" >> hellodba.repo
[root@hellodba yum.repos.d]# echo "name=Linux 7.9 DVD" >> hellodba.repo
[root@hellodba yum.repos.d]# echo "baseurl=file:///mnt" >> hellodba.repo
[root@hellodba yum.repos.d]# echo "gpgcheck=0" >> hellodba.repo
[root@hellodba yum.repos.d]# echo "enabled=1" >> hellodba.repo

net.core.wmem_max = 1048586
#当系统检测到oops时,重新启动系统,以便系统能够重新初始化恢复正常工作
kernel.panic_on_oops = 1
#单个共享内存段最大值,让数据库在一个共享段里面的可以容纳整个SGA
#SGA=物理内存*80%*80% PGA=物理内存*80%*20%
#(kernel.shmmax = 物理内存*1024*1024*1024-1)
kernel.shmmax = 9620726743
#控制共享内存页数(kernel.shmall = shmmax/4096)
kernel.shmall = 2348810
#共享内存的最大数量
kernel.shmmni = 4096
#当系统内存使用90%的时候开始使用交换页面
vm.swappiness=10
#默认是100,增大这个参数设置了虚拟内存回收directory和i-node缓冲的倾向,这个值越大。越容易回收。
vm.vfs_cache_pressure=200
#大页内存,物理内存大于8G一定要配 (sga_max_size+1g) / 2M
vm.nr_hugepages = 4000

[root@hellodba ~]# sysctl -p
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
