怎么将RMAN备份文件放到ASM中

本篇内容介绍了"怎么将RMAN备份文件放到ASM中"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

一、问题描述

此次，我们希望将RMAN备份出来的文件放到ASM当中存储，这个操作不太难，就是正常的RMAN脚本，将format输出到正确的磁盘组就好。

二、实践

1.在磁盘组中建立目录

[grid@sam1 ~]$ asmcmd -pASMCMD [+] > cd +flashbackASMCMD [+flashback] > mkdir backupASMCMD [+flashback] > lsPROD/backup/cluster/

2.准备备份脚本

run {allocate channel ch2 type disk;allocate channel ch3 type disk;backup as compressed backupset database format '+FLASHBACK/backup/db_%T_%U.bak'  plus archivelog  format '+FLASHBACK/backup/arch_%T_%U.bak';backup current controlfile format '+FLASHBACK//backup/ctl_%T_%U.bak';release channel ch2;release channel ch3;}

3.RAMN执行脚本

[oracle@sam1 ~]$ rman target /Recovery Manager: Release 11.2.0.3.0 - Production on Wed Feb 26 04:26:00 2020Copyright (c) 1982, 2011, Oracle and/or its affiliates.

5.可以将ASM中的备份文件复制到文件系统中

（1）直接cp文件到操作系统中，只能一个一个文件复制

ASMCMD [+flashback/backup] > cp arch_20200226_06upflvi_1_1.bak /home/gridcopying +flashback/backup/arch_20200226_06upflvi_1_1.bak -> /home/grid/arch_20200226_06upflvi_1_1.bak

利用通配符也是只复制一个文件

ASMCMD [+flashback/backup] > cp *.* /home/gridcopying +flashback/backup/arch_20200226_06upflvi_1_1.bak -> /home/grid/arch_20200226_06upflvi_1_1.bakASMCMD [+flashback/backup] >

（2）使用shell脚本批量将文件从ASM拷贝到文件系统（ASMCMD 中的cp 命令不能使用通配符 * ，只能通过脚本实现批量拷贝）

[grid@sam1 ~]$ cat asmcp.sh #!/bin/sh export ORACLE_SID=+ASM1echo  " Start to copy backupfile from ASM to file system ...." asmcmd   <<  EOF  cd  flashback/backup   cp arch_20200226_06upflvi_1_1.bak /home/grid  cp arch_20200226_07upflvi_1_1.bak /home/grid  cp arch_20200226_08upflvp_1_1.bak /home/grid  cp arch_20200226_0dupfm17_1_1.bak /home/grid  cp ctl_20200226_0eupfm18_1_1.bak /home/grid  cp db_20200226_09upflvq_1_1.bak /home/grid  cp db_20200226_0aupflvq_1_1.bak /home/grid  cp db_20200226_0bupfm0t_1_1.bak /home/grid  cp db_20200226_0cupfm0v_1_1.bak /home/gridEOF[grid@sam1 ~]$ chmod u+x asmcp.sh [grid@sam1 ~]$ ls -l asmcp.sh -rwxr--r-- 1 grid oinstall 562 Feb 26 06:41 asmcp.sh[grid@sam1 ~]$ ./asmcp.sh Start to copy backupfile from ASM to file system ....ASMCMD> ASMCMD> copying +flashback/backup/arch_20200226_06upflvi_1_1.bak -> /home/grid/arch_20200226_06upflvi_1_1.bakASMCMD> copying +flashback/backup/arch_20200226_07upflvi_1_1.bak -> /home/grid/arch_20200226_07upflvi_1_1.bakASMCMD> copying +flashback/backup/arch_20200226_08upflvp_1_1.bak -> /home/grid/arch_20200226_08upflvp_1_1.bakASMCMD> copying +flashback/backup/arch_20200226_0dupfm17_1_1.bak -> /home/grid/arch_20200226_0dupfm17_1_1.bakASMCMD> copying +flashback/backup/ctl_20200226_0eupfm18_1_1.bak -> /home/grid/ctl_20200226_0eupfm18_1_1.bakASMCMD> copying +flashback/backup/db_20200226_09upflvq_1_1.bak -> /home/grid/db_20200226_09upflvq_1_1.bakASMCMD> copying +flashback/backup/db_20200226_0aupflvq_1_1.bak -> /home/grid/db_20200226_0aupflvq_1_1.bakASMCMD> copying +flashback/backup/db_20200226_0bupfm0t_1_1.bak -> /home/grid/db_20200226_0bupfm0t_1_1.bakASMCMD> copying +flashback/backup/db_20200226_0cupfm0v_1_1.bak -> /home/grid/db_20200226_0cupfm0v_1_1.bakASMCMD> exit[grid@sam1 ~]$ ls -l *.bak-rw-r----- 1 grid oinstall  42693632 Feb 26 06:50 arch_20200226_06upflvi_1_1.bak-rw-r----- 1 grid oinstall  35036160 Feb 26 06:50 arch_20200226_07upflvi_1_1.bak-rw-r----- 1 grid oinstall   3460608 Feb 26 06:50 arch_20200226_08upflvp_1_1.bak-rw-r----- 1 grid oinstall     43008 Feb 26 06:50 arch_20200226_0dupfm17_1_1.bak-rw-r----- 1 grid oinstall  18546688 Feb 26 06:50 ctl_20200226_0eupfm18_1_1.bak-rw-r----- 1 grid oinstall 437977088 Feb 26 06:50 db_20200226_09upflvq_1_1.bak-rw-r----- 1 grid oinstall 320684032 Feb 26 06:50 db_20200226_0aupflvq_1_1.bak-rw-r----- 1 grid oinstall   1114112 Feb 26 06:50 db_20200226_0bupfm0t_1_1.bak-rw-r----- 1 grid oinstall     98304 Feb 26 06:50 db_20200226_0cupfm0v_1_1.bak
