-- 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。

 

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;

 

        List of Stored Scripts in Recovery Catalog

 

            Scripts of Target Database ORCL

 

               Script Name

               Description

               -----------------------------------------------------------------------

               ctl_spfile_bk

 

               full_backup

               A script for full backup to be used with current target database

 

            Global Scripts

 

               Script Name

               Description

               -----------------------------------------------------------------------

               global_full_backup

               A script for full backup to be used with any database

 

四、更新脚本

    replace [global] script scrip_name {....}

    replace [global] script script_name from file ‘<dir>‘  --从文件更新脚本

 

    RMAN> replace global script global_full_backup

    2> {

    3>   backup as compressed backupset database plus archivelog

    4>   tag=‘whole_db_bk‘;

    5>   delete obsolete;

    6> }

 

    replaced global script global_full_backup

    

五、执行脚本

    方法：RUN { EXECUTE [global] SCRIPT script_name; }

    从rman客户端直接执行恢复目录内的脚本

        rman target sys/redhat@orcl catalog rman/rman@asmdb script ‘script_name‘;

 

    RMAN> run { execute global script global_full_backup;}

 

    executing global script: global_full_backup

 

六、删除脚本

    delete [global] script script_name

    

    RMAN> delete script ctl_spfile_bk;

 

    deleted script: ctl_spfile_bk

 

七、其它

    注意：使用EXECUTE SCRIPT, DELETE SCRIPT ,PRINT SCRIPT等命令时，如果一个本地的脚本未找到，则寻找全局的脚本来代替。

    因此应当注意命名规范，尽可能的不使用重名的脚本名，当DELETE SCRIPT 找不到本地脚本，而找到同样名字的全局脚本，则全局

    脚本被删除
