因為時不時要搭個oracle 的dataguard，想偷個懶，根據自己的一些理解做了一個自動配置環境，

自動rman duplicate 復制來實現搭建oracle dg 的小工具，工具目前還不是特別完善，希望圈內各位前輩多多指點，多踩踩，有興趣的小伙伴可以一起完善完善；

AutoDG oracle dataguard 自動搭建小工具，目前只支持linux 平臺，Oracle11g 及以上版本

github代碼連接：https://github.com/theone1900

功能參數使用說明
##check 參數 主庫環境預檢查

主要檢查數據庫版本是否大于11201
主庫歸檔模式 & force_logging 是否開啟
主庫密碼文件orapwd$SID是否存在
主庫是否使用spfile
##prepare 參數 主庫環境檢查,主備環境初始化，自動搭建oracle dataguard

主庫更新tnsnames.ora
下載主庫tnsnames.ora，orapwd 密碼文件
本地備庫tnsnames.ora orapwd 文件同步
本地備庫adump 等目錄配置
本地備庫listener.ora 初始化
本地備庫pfile 初始化
本地備庫啟動到 nomount 狀態
本地備庫執行rman duplicate 命令
使用事項

4、配置 autodg 參數文件，config.toml 相關參數配置說明見 conf/config.toml

5、主庫環境檢查
$ ./autodg --config config.toml --mode check

6、自動配置dataguard 環境編輯，數據庫同步備份等
$ ./autodg --config config.toml --mode prepare
prepare 模式

/* 數據庫開啟歸檔以及補充日志 */
-- 開啟歸檔【必須選項】
alter database archivelog;
-- 強制日志【必須選項】
ALTER DATABASE force log ;


若直接在命令行中用 `nohup` 啟動程序，可能會因為 SIGHUP 信號而退出，建議把 `nohup` 放到腳本里面且不建議用 kill -9，如：

```shell
#!/bin/bash
nohup ./autodg -config config.toml --mode check > nohup.out &
