**！！！原文出处，国外大佬写的，安装过程中的问题一样，解决方案全都有效：**[https://ahmedfattah.com/2020/01/13/oracle-database-19c-installation-on-oracle-cloud-compute-instance/][https_ahmedfattah.com_2020_01_13_oracle-database-19c-installation-on-oracle-cloud-compute-instance]

## 安装 ##

> Step1：该包将为 Oracle 软件安装准备环境（安装所需的包、创建用户、创建目录、设置限制等）。

curl -o oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm
    
    yum -y install oracle-database-preinstall-19c

> Step2: Download the Oracle Database 19c Software

wget https://www.oracle.com/database/technologies/oracle19c-linux-downloads.html
    
    yum -y localinstall oracle-database-ee-19c-1.0-1.x86_64.rpm

> Step3：创建和配置 Oracle 数据库

/etc/init.d/oracledb_ORCLCDB-19c configure

将会遇到的问题及解决办法如下：

> 问题1
> 
>  *  `[WARNING] ORA-04031: unable to allocate 1048848 bytes of shared memory (“shared pool”,”unknown object”,”PDB Dynamic He”,”alls-ktimcem”)`
>  *  `[WARNING] ORA-04031: unable to allocate 1048848 bytes of shared memory (“shared pool”,”unknown object”,”PDB Dynamic He”,”alls-ktimcem”)`

Oracle 根据系统物理内存的 40% 实时计算 memory\_target 的值。

解决方法，在对应的配置文件中修改这个默认的参数值：

cd /opt/oracle/product/19c/dbhome_1/assistants/dbca/templates/
    vim General_Purpose.dbc

![修改内存容量比][watermark_type_ZHJvaWRzYW5zZmFsbGJhY2s_shadow_50_text_Q1NETiBAYmx0c2U_size_20_color_FFFFFF_t_70_g_se_x_16 2]  
将其从 40 修改为 70 或更多。

在再次运行命令之前，由于之前命令失败，需要先做一些清理：

> 杀死该进程，并删除网络配置

/opt/oracle/product/19c/dbhome_1/bin/lsnrctl stop
    
    ls /opt/oracle/product/19c/dbhome_1/network/admin
    rm -rf *.ora

> 重新运行

/etc/init.d/oracledb_ORCLCDB-19c configure

最后，数据库成功创建：
