1.1 查看操作系统版本
RHEL7.9
bash
[root@lu9up01 ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.9 (Maipo)1.2 内存大小
至少1G，建议2G以上
bash
[root@lu9up01 ~]# free -g
total used free shared buff/cache available
Mem: 7 0 0 0 7 7
Swap: 7 0 71.3 共享内存段
共享内存段/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%。/dev/shm大小应该大于SGA+PGA的总内存大小，如果/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。
bash
[root@lu9up01 ~]# df -h /dev/shm/
Filesystem Size Used Avail Use% Mounted o
tmpfs 3.8G 0 3.8G 0% /dev/shm1.4 /tmp目录
/tmp目录要求超过1G
bash
[root@lu9up01 ~]# df -h /tmp
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 41G 7.2G 34G 18% /1.5 交换分区Swap空间
- 当物理内存在4GB到16GB时，要求Swap等于内存值
- 当物理内存超过16GB时，要求Swap等于16GB
bash
[root@lu9up01 ~]# free -g

bash
[root@lu9up01 ~]# echo never > /sys/kernel/mm/transparent_hugepage/enabled
[root@lu9up01 ~]# echo never > /sys/kernel/mm/transparent_hugepage/defrag
[root@lu9up01 ~]# cat /sys/kernel/mm/transparent_hugepage/enabled
always madvise [never]
[root@lu9up01 ~]# cat /sys/kernel/mm/transparent_hugepage/defrag
always defer defer+madvise madvise [never]都是[never]就可以
1.7 主机名和映射

2 静默安装Oracle数据库软件
2.1 安装包准备
上传安装包到$ORACLE_HOME下并解压：
bash
cd $ORACLE_HOME
unzip LINUX.X64_193000_db_home.zip重新设置所属用户组：
bash
chown -R oracle:oinstall /u01/app/oracle2.2 编辑响应文件
备份：
bash
su - oracle
cd $ORACLE_HOME/install/response
cp db_install.rsp /tmp修改配置：
bash
vi db_install.rsp修改文件中以下内容（这些是比较关键的，其余的配置按需更改）：
bash
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1

oracle.install.db.config.starterdb.SID=lu9up
oracle.install.db.config.starterdb.storageType=FILE_SYSTEM_STORAGE2.3 静默安装数据库软件
bash
$ cd $ORACLE_HOME
$ ./runInstaller -silent -ignorePrereq -responseFile $ORACLE_HOME/install/response/db_install.rsp安装日志：
bash

不需要修改响应文件，默认安装就好。
bash
$ netca -silent -responsefile $ORACLE_HOME/assistants/netca/netca.rsp安装完成后查看监听状态：

4.1 备份响应文件
bash
$ cd $ORACLE_HOME/assistants/dbca
$ cp dbca.rsp /tmp4.2 编辑响应文件
bash
$ vim dbca.rsp
