-- 基于catalog 创建RMAN存储脚本

简言之，将rman的备份恢复命令写成脚本并保存在恢复目录内，恢复目录内的脚本可用性及通用性高于基于文件系统的脚本。

客户端只要能够登录到RMAN恢复目录，则这些脚本可用，尤其对于global脚本，可以被任意注册的数据库调度。哈哈哈哈哈哈

关于如何创建恢复目录数据库及恢复目录脚本，此处省略，请参考:

RMAN catalog 的创建和使用

基于catalog 创建RMAN存储脚本

基于catalog 的RMAN 备份与恢复

一、脚本的分类

local : 在rman连接的目标数据库下创建的脚本，此类脚本仅仅适用于当前目标数据库。即是针对特定的数据库创建的rman脚本

global : 能够在恢复目录注册的任意目标数据库中执行

 

二、创建脚本

--创建全局备份脚本

RMAN> create global script global_full_backup

2> comment 'A script for full backup to be used with any database'

3> {

4>backup database

5>plus archivelog

6>tag='Whole_db_bk';

7>delete obsolete;

8> }

 

created global script global_full_backup

 

--创建本地备份脚本

RMAN> create script full_backup

2> comment 'A script for full backup to be used with current target database'

3> {

4>backup as compressed backupset

5>database plus archivelog delete input

6>tag='Whole_db_bk';

7>delete obsolete;

8> }

 

created script full_backup

 

--从文本文件创建脚本

[Oracle@oradb bk]$ cat backup_ctl_spfile--注意文本文件必须以"{" 开头，以"}" 结尾

{

allocate channel ch1 device type disk;

backup current controlfile

tag='ctl_spfile'

format '/u01/oracle/bk/rmbk/ctl_spfile_%d_%U';

release channel ch1;

}

 

RMAN> create script ctl_spfile_bk from file '/u01/oracle/bk/rmbk/backup_ctl_spfile';

 

script commands will be loaded from file /u01/oracle/bk/rmbk/backup_ctl_spfile

created script ctl_spfile_bk

 

三、查看脚本的内容

print [global] script script_name

print [global] script script_name to file '<dir>'--将RMAN存储脚本转换到文件系统可读文件

 

RMAN> print script ctl_spfile_bk;

 

printing stored script: ctl_spfile_bk

{

allocate channel ch1 device type disk;

backup current controlfile

tag='ctl_spfile'

format '/u01/oracle/bk/rmbk/ctl_spfile_%d_%U';

release channel ch1;

}

 

RMAN> print script ctl_spfile_bk to file '/u01/oracle/bk/rmbk/backup_ctl_spfile2';

 

script ctl_spfile_bk written to file /u01/oracle/bk/rmbk/backup_ctl_spfile2

 

查看当前恢复目录内的脚本

list [global | all] script names

 

RMAN> list script names;
