Nocatalog 下的RMAN 增量备份 shell脚本

發(fā)布時(shí)間：2025/3/15 编程问答 31 豆豆

生活随笔收集整理的這篇文章主要介紹了 Nocatalog 下的RMAN 增量备份 shell脚本小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

?????? 之前整理了下catalog下全備的腳本，上次在生產(chǎn)庫(kù)上弄了個(gè)nocatalog的腳本，結(jié)果沒(méi)有在本本上保存，這次要用了，重新在整理了一下。

Linux 平臺(tái)下 RMAN 全備和增量備份 shell 腳本

http://blog.csdn.net/tianlesoftware/archive/2010/07/16/5740630.aspx

在執(zhí)行腳本之前，先修改幾個(gè)參數(shù)值：

1. DB 參數(shù)：

修改控制文件的保存時(shí)間，從默認(rèn)的7天改成14天

SQL> show parameter control

SQL> alter system set control_file_record_keep_time=14 scope=both;

2. RMAN 參數(shù)：

開啟控制文件的自動(dòng)備份，開啟之后在數(shù)據(jù)庫(kù)備份或者數(shù)據(jù)文件（比如添加數(shù)據(jù)文件）有修改的時(shí)候都會(huì)自動(dòng)備份控制文件和spfile文件。

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;

RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;

3. 備份策略根據(jù)自己的系統(tǒng)決

?????? 我這里是周日做0級(jí)備份。周四1級(jí)備份，其他2級(jí)備份。

4. 備份腳本如下：
