Oracle 12.2安装示例数据库schema
Oracle 12.2安装示例数据库schema
在做Oracle数据库实验时都会用到一些示例SCHEMA如：HR、OE、SH等，在Oracle11g版本时在DBCA时直接勾选Sample Schemas就可以安装这些示例SCHEMA，如下图：
但到了Oracle12.2 版本，也有一个示例Schemas选项卡如下图所示：
但是数据库安装完成后却还是没有这些示例SCHEMA，到底是怎么回事呢？我们来查一下官方文档：
Starting with Oracle Database 12c Release 2, the latest version of the sample schema scripts are available on GitHub at https://github.com/oracle/db-sample-schemas/releases/latest.
During a complete installation of Oracle Database, the HR schema can be installed either manually or automatically when creating a database using the dbca option. All the other sample schemas must be installed manually via the scripts available on GitHub.
从上面的官方文档中我们可以看到从Oracle12.2版本开始，示例Schemas的脚本被放到了GitHub上，在DBCA安装时只会安装hr示例Schema。从文档中给出的指定地址下载示例Schema安装脚本：
同步下载：
git clone https://github.com/oracle/db-sample-schemas.git
将文件放于$ORACLE_HOME/demo/ 目录下.
从README.txt文档中找到安装方法，开始安装：

重新查看README.md文档看到需要把“__SUB__CWD__”这个变量替换为当前路径，还给出了命令：
[oracle@rhel7 db-sample-schemas-12.2.0.1]$ perl -p -i.bak -e 's#__SUB__CWD__#'$(pwd)'#g' *.sql */*.sql */*.dat执行完上面的脚本后重新安装示例Schema：
sys@ORA12C>@mksample 123456 123456 hr oe pm ix sh bi users temp /home/oracle/dbca/ 192.168.56.22:1521/ora12c最终安装成功：
