rman备份脚本

在数据库中启用块跟踪

alter database enable block change tracking；

alter database enable block change tracking using file '/u01/app/oracle/track/blockchange.trc'；

取消块跟踪

alter database disable block change tracking

查看是否启动块跟踪

SQL> select * from v$block_change_tracking;

在RMAN 下执行：

备份文件：

  CONFIGURE BACKUP OPTIMIZATION ON

  CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/orahome/oracle/zjgd_back/%T/%U';

  CONFIGURE CHANNEL DEVICE TYPE DISK clear;

控制文件：

  CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/orahome/oracle/zjgd_back/%T/%F';

snap： 

  CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/orahome/oracle/zjgd_back/snapcf_zjgd.f';

%c 备份片的拷贝数(从1开始编号);

%d 数据库名称；

%D 位于该月中的天数 (DD);

%M 位于该年中的月份 (MM);

%F 一个基于DBID唯一的名称，这个格式的形式为c-xxx-YYYYMMDD-QQ,其中xxx为该数据库的DBID,YYYYMMDD为日期，QQ是一个1-256的序列;

%n 数据库名称,并且会在右侧用x字符进行填充，使其保持长度为8;

%u 是一个由备份集编号和建立时间压缩后组成的8字符名称。利用%u可以为每个备份集生成一个唯一的名称；

%p 表示备份集中备份片段的编号，从1开始编号;

%U 是%u_%p_%c的简写形式，利用它可以为每一个备份片段(即磁盘文件)生成一个唯一名称，这是最常用的命名方式;

%s 备份集的号;

%t 备份集时间戳;

%T 年月日格式(YYYYMMDD);

 

你可以在备份的时候指定~比如

RMAN> backup current controlfile format'/home/oracle/%d_%M_%D'

RMAN> configure controlfile autobackup on;

new RMAN configuration parameters:

CONFIGURE CONTROLFILE AUTOBACKUP ON;

new RMAN configuration parameters are successfully stored

RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/u01/app/oracle/backup/%T%U'

2> ;

new RMAN configuration parameters:

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/u01/app/oracle/backup/%T%U';

new RMAN configuration parameters are successfully stored
