Oracle 19C 的下载和安装部署（图形安装和静默安装）
https://docs.oracle.com/en/database/oracle/oracle-database/19/ladbi/operating-system-checklist-for-oracle-database-installation-on-linux.html
Oracle Database 19c，也就是 12.2.0.3，最初在 livesql.oracle.com 上发布，是 Oracle Database 12c 和 18c 系列产品的最终版本，因此也是“长期支持”版本（以前称为“终端版本”）。“长期支持”意味着 Oracle Database 19c 提供 4 年的高级支持（截止到 2023 年 1 月底）和至少 3 年的延长支持（截至 2026 年 1 月底）。这个扩展的支持窗口对我们的很多客户至关重要，因为很多客户制定了相关的升级策略。有关最新的 Oracle 支持计划，请参阅 My Oracle Support 上的文档 ID 742060.1。截止目前，Oracle Database 19c 已经可以在 Oracle 数据库一体机上使用了。
Oracle12c 版本的说明：
Oracle12cR2=12.2.0.1
Oracle18C=12.2.0.2
Oracle19c=12.2.0.3
在 MOS 官方文章：Release Schedule of Current Database Releases (文档 ID 742060.1) 上，可以清晰的看到 Oracle 的版本计划。
Oracle Database 19c 的目标
Oracle Database 19c 是大多数客户准备要升级的版本，Oracle 已将 稳定性 作为此版本的核心目标。在 Oracle Database 19c 中，开发人员专注于修复已知问题，而不是添加新功能。在数年内我们已有数百人和数千台服务器每天 24 小时的运行测试。测试包括数据库的核心、安装程序，再到组成产品的子程序及实用工具的堆栈等所有方面。目标只有一个，保证数据库的稳定性。真正的为客户带来实惠。
在 Linux 上安装 Oracle Database 19c，需要 OL7、RHEL7、SLES12 及以上的更高版本。下面的内容来自官方文档
The following Linux x86-64 kernels are supported:
Oracle Linux 7.4 with the Unbreakable Enterprise Kernel 4: 4.1.12-112.16.7.el7uek.x86_64 or later
Oracle Linux 7.4 with the Unbreakable Enterprise Kernel 5: 4.14.35-1818.1.6.el7uek.x86_64 or later
Oracle Linux 7.4 with the Red Hat Compatible kernel: 3.10.0-693.5.2.0.1.el7.x86_64 or later
Red Hat Enterprise Linux 7.4: 3.10.0-693.5.2.0.1.el7.x86_64 or laterSUSE Linux Enterprise Server 12 SP3: 4.4.103-92.56-default or later
Oracle Enterprise Linux6 和 RedHat Linux6 并没有出现在官方给的列表中。随着时间的推移，不只是要升级操作系统，还要升级数据库。要做好升级规划。要不后期就会有意想不到的问题。19c 也就是 12.2.0.3，是 12c 系列里面的终极版本，重在稳定！

这里可以自动跑 root 脚本，不需要在单独跑 root 了
[root@oracle-server001 19]# /u01/app/oracle19/product/19.2.0/db_1/root.sh
[oracle19@oracle-server001 db_1]$ netca
[oracle19@oracle-server001 db_1]$ dbca
静默部分
V981623-01 db 19.2.0.0.0.zip 安装包大概 2.82G，解压后有 6.5G，数据库软件安装完成后有 7G，创建完数据库后有 10G。
从 Oracle 18c 开始，在安装数据库软件时，需要把压缩文件解压到 $ORACLE_HOME 路径下，在此目录下运行 ./runInstaller
创建用户 oracle19：
/usr/sbin/useradd -g oinstall -G oper,dba,asmdba,backupdba,dgdba,kmdba,racdba oracle19
passwd oracle19
mkdir -p /u19/app/oracle/product/19.2.0/dbhome_1
mkdir -p /u19/app/oraInventory
chown -R oracle19:oinstall /u19/app
创建环境变量：
vi .bash_profile
umask 022
export ORACLE_SID=lhr19c
export ORACLE_BASE=/u19/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.2.0/dbhome_1

1、测试可以在 CentOS 7.3 环境上安装，但是在 RHEL6.5 上不能安装
2、在安装过程中可以设置 root.sh 脚本自动执行
Oracle 19c（19.3）可以在 OTN 网站（https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle19c-linux-5462157.html）下载了，也可以去 Oracle 的云下载地址（https://edelivery.oracle.com）进行下载。本文是基于 19.2 版本的。
