碰到Oracle 在windows服务器上，asp.net core web api 在linux的docker中
碰到问题
说ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region not found
这应该是服务器时区和oracle不一致导致的， docker默认时区都是 Etc/UTC，而我的Oracle 数据库中没有这个时区
解决：
通过语句可以查看到Oracle有哪些时区
select tzname, tzabbrev from v$timezone_names
我这里 亚洲的只有重庆，所以，我下面的操作都是选的重庆
在网上找了好多资料，有的说，改oracle什么配置文件，加什么参数，都没有用。
有的说改docker 时区，确实是的，但是好多方法都不能用，也没有说明白。
我的操作系统是 Ubuntu 16.04 修改时区！ 尝试各种各种改时区的方法，都没有用。
我的解决办法
1、进入docker
docker exec d7f -it /bin/bash //d7f 是容器的id或名称，我这里是id
2、执行命令：dpkg-reconfigure tzdata
root@d7f2ead6bdfa:/app# dpkg-reconfigure tzdata
debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline

Time zone: 19
Current default time zone: 'Asia/Chongqing'
Local time is now: Mon Nov 12 12:56:26 CST 2018.
Universal Time is now: Mon Nov 12 04:56:26 UTC 2018.
一步一步选下来，选你自己要的时区
3、验证
root@d7f2ead6bdfa:/app# dpkg-reconfigure -f noninteractive tzdata
Current default time zone: 'Asia/Chongqing'
Local time is now: Mon Nov 12 12:56:32 CST 2018.
Universal Time is now: Mon Nov 12 04:56:32 UTC 2018.
看我的时区已经改了，我这里重启了一下容器，程序跑起来了。
