由于docker安装的oracle 12c有很多莫名其妙的bug，很多正常的SQL被它报错，比如：
SYS@lhrcdb1> @/par/day9.sql where case when s.sid>s.cnt-2 then s.sid+2-s.cnt else s.sid+2 end=s1.sid * ERROR at line 24: ORA-00923: FROM keyword not found where expected基本无法使用。所以又重新拉取了oracle 19c的镜像，在建立容器的时候，遇到一些问题。
记录如下：
- 拉取oracle 19c的镜像

- 运行容器
第一次用了上次12c的同样命令行，结果出错了。

然后看到了这篇文章, 里面提到很重要的一点是，
2.4 查看安装过程 执行运行命令后，可以马上执行日志查看命令。创建实例的过程会比较长，请耐心等待。 docker logs -ft oracle19c执行docker logs -ft oracle19c在日志中看到一个明显的出错信息

再次关闭并删除错误的容器，重新运行刚才的docker run命令，并观察安装进度日志。
