在Oracle 12CR2中在创建数据库时不能安装sample schemas，Oracle将sample schemas的安装脚本存储在GitHub上了，可以通过以下链接地址进行下载
https://github.com/oracle/db-sample-schemas/releases/latest
下载到的是一个zip文件，例如我下载的文件名为db-sample-schemas-12.2.0.1.zip，将其解压
[oracle@jytest1 schema]$ unzip db-sample-schemas-12.2.0.1.zip [oracle@jytest1 schema]$ ls -lrt total 36584 -rw-r--r-- 1 oracle oinstall 2322 Apr 3 2009 drop_sch.sql -rw-r--r-- 1 oracle oinstall 16894 Jul 1 2014 sted_mkplug.sql.dbl -rw-r--r-- 1 oracle oinstall 27570 Jul 1 2014 mkplug.sql -rw-r--r-- 1 oracle oinstall 1685 Nov 6 2015 mk_dir.sql.sbs drwxr-xr-x 2 oracle oinstall 6 Mar 20 19:50 log -rw-r--r-- 1 oracle oinstall 1824 Mar 20 19:51 mk_dir.sql drwxr-xr-x 2 oracle oinstall 4096 May 18 17:12 human_resources -rw-r--r-- 1 oracle oinstall 37389564 May 18 17:48 db-sample-schemas-12.2.0.1.zip drwxrwxrwx 10 oracle oinstall 4096 May 18 18:46 db-sample-schemas-12.2.0.1
创建sample schemas只需执行db-sample-schemas-12.2.0.1目录下的mksample.sql脚本,其语法如下:
mksampleEXAMPLE TEMP $ORACLE_HOME/demo/schema/log/ localhost:1521/pdb
其参数分别指system,sys,hr,oe,pm,ix,sh,bi用户的密码，与缺省表空间，临时表空间名，以及存储生成日志文件的目录和连接数据库的连接串
[oracle@jytest1 db-sample-schemas-12.2.0.1]$ sqlplus /nolog

上面的错误显示不能打开__SUB__CWD__/目录下的相关脚本文件，这里我们需要将__SUB__CWD__/目录使用相关脚本存储的目录的绝对路径来替，下面执行替换
[oracle@jytest1 db-sample-schemas-12.2.0.1]$ perl -p -i.bak -e 's#__SUB__CWD__#'$(pwd)'#g' *.sql */*.sql */*.dat
重新执行
