因为时不时要搭个oracle 的dataguard，想偷个懒，根据自己的一些理解做了一个自动配置环境，
自动rman duplicate 复制来实现搭建oracle dg 的小工具，工具目前还不是特别完善，希望圈内各位前辈多多指点，多踩踩，有兴趣的小伙伴可以一起完善完善；
AutoDG oracle dataguard 自动搭建小工具，目前只支持linux 平台，Oracle11g 及以上版本
github代码连接：https://github.com/theone1900
功能参数使用说明
##check 参数 主库环境预检查
主要检查数据库版本是否大于11201
主库归档模式 & force_logging 是否开启
主库密码文件orapwd$SID是否存在
主库是否使用spfile
##prepare 参数 主库环境检查,主备环境初始化，自动搭建oracle dataguard
主库更新tnsnames.ora
下载主库tnsnames.ora，orapwd 密码文件
本地备库tnsnames.ora orapwd 文件同步
本地备库adump 等目录配置
本地备库listener.ora 初始化
本地备库pfile 初始化
本地备库启动到 nomount 状态
本地备库执行rman duplicate 命令
使用事项
4、配置 autodg 参数文件，config.toml 相关参数配置说明见 conf/config.toml
5、主库环境检查
$ ./autodg --config config.toml --mode check
6、自动配置dataguard 环境编辑，数据库同步备份等
$ ./autodg --config config.toml --mode prepare
prepare 模式
/* 数据库开启归档以及补充日志 */
-- 开启归档【必须选项】
alter database archivelog;
-- 强制日志【必须选项】
ALTER DATABASE force log ;
若直接在命令行中用 `nohup` 启动程序，可能会因为 SIGHUP 信号而退出，建议把 `nohup` 放到脚本里面且不建议用 kill -9，如：
```shell
#!/bin/bash
nohup ./autodg -config config.toml --mode check > nohup.out &
