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 -p ASMCMD [+] > cd +flashback ASMCMD [+flashback] > mkdir backup ASMCMD [+flashback] > ls PROD/ 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 2020 Copyright (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/grid copying +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/grid copying +flashback/backup/arch_20200226_06upflvi_1_1.bak -> /home/grid/arch_20200226_06upflvi_1_1.bak ASMCMD [+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=+ASM1 echo " 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/grid EOF [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 ....
