二、正式库进行RMAN备份
RMAN全备脚本
cat /home/oracle/scripts/rman_full.sh
#!/bin/bash
source ~/.bash_profile
TODAYdate %Y-%m-%d
rman target / nocatalog EOF
spool log to /home/oracle/scripts/logs/$TODAY.full_backup.log;
run{
allocate channel c1 device type disk;
backup as compressed backupset filesperset 2 database format /backup/level0_%d_%t_%s_%p tag L0;
sql alter system archive log current;
backup as compressed backupset archivelog all format /backup/arc_%t_%s;
backup current controlfile format /backup/cntrl_%s_%p_%s;
release channel c1;
}
crosscheck backup;
crosscheck archivelog all;
delete noprompt expired backup;
delete noprompt obsolete;
EOF执行备份脚本
sh /home/oracle/scripts/rman_full.sh查看备份log 备份正常查看备份文件 正式库生成参数文件
三、将正式库备份与参数文件拷贝到测试库
scp命令传输
传输备份文件 传输参数文件 测试库文件检查
检查备份文件 检查参数文件 四、测试库异机恢复
编辑参数文件 创建spfile将数据库启动到nomount状态
create spfile from pfile/home/oracle/pfile/ora;
startup nomount;恢复控制文件将数据库启动到mount状态
restore controlfile from /backup/cntrl_19_1_19;注册备份集
catalog start with /backup/;#crosscheck核对数据文件备份集
crosscheck backup;restore database
run{allocate channel t1 type disk;allocate channel t2 type disk;restore database;switch datafile all;release channel t2;release channel t1;
}recover database
recover database;开启数据库
alter database open resetlogs;检查数据库
select name,open_mode from v$database;
select file_name from dba_temp_files;
select member from v$logfile;
show parameter name五、验证数据
