rman 示例

　

• 每周日1点数据库全备
• 每天8点备份归档

　[ora11204@OEL-ASM scripts]$ crontab -l 0 1 * * 0 /u01/orabak/scripts/backup.sh /u01/orabak 0 8 * * * /u01/orabak/scripts/backuparch.sh /u01/oraba

• 全备脚本：vi backup.sh

#!/bin/bash
#ENV

• 归档备份脚本：vi backuparch.sh
  这里只是去掉全备的命令，其他保留。

#!/bin/bash
#ENV
export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 export PATH=$ORACLE_HOME/bin:$PATH #backup RMAN if [ ! -d "$1" ]; then echo "You have input no dir for \$1" exit 1 fi echo "=================================================================================" >>${1}/backup_arch.log echo "Begin backup at : `date`" >> ${1}/backup_arch.log rman target / <<EOF >> ${1}/backup_arch.log run { CONFIGURE RETENTION POLICY TO REDUNDANCY = 2; CONFIGURE DEVICE TYPE DISK PARALLELISM 6; CONFIGURE DEFAULT DEVICE TYPE TO DISK; backup current controlfile format '${1}/%d.%s.%p.%T.CTL'; backup spfile format '${1}/%d.%s.%p.%T.SPFILE'; crosscheck backup; crosscheck copy; sql "alter system archive log current"; backup as COMPRESSED backupset archivelog all not backed up format '${1}/%d.%s.%p.%T.ARC'; crosscheck archivelog all; delete noprompt archivelog all completed before 'sysdate-10'; delete noprompt expired backup; delete noprompt obsolete; } exit EOF echo "End backup at : `date`" >>${1}/backup_arch.log echo "Begin scp at : `date`" >>${1}/backup_arch.log scp ${1}/*`date +%Y%m%d`*.{CTL,SPFILE,ARC} [email protected]:/tmp/ echo "End scp at : `date`" >>${1}/backup_arch.log echo "=================================================================================" >>${1}/backup_arch.log exit 0

参数文件：

 控制文件：

RMAN> restore controlfile from '/tmp/ORCL.23.1.20180619.CTL';
RMAN> alter database mount;
RMAN> catalog start with '/tmp/';
RMAN> crosscheck backup;

转储文件并恢复到指定时间点：

RMAN> restore database;
RMAN> sql "alter session set nls_date_format=''yyyy-mm-dd hh24:mi:ss''";
RMAN> recover database until time '2018-06-19 17:50:00';

--先只读打开确认数据是否符合要求
SQL> alter database open read only; --确认没问题后重新以resetlogs方式打开 SQL> create spfile from pfile='/u01/oradata/orcl/pfile.ora'; SQL> startup mount SQL> alter database open resetlogs;
