模拟数据库崩溃，删除控制文件，此时数据库还在继续运行，可能要过一会切换日志崩溃。这里我直接重启一下数据库

3.1  假定没有设置Oracle_SID,设置Oracle_SID启动一个伪实例


$ORACLE_SID查看原来的SID。这里是假设原来$ORACLE_SID没设置的情况下：

[[email protected] ~]$ echo $ORACLE_SID

3.2  恢复spfile


RMAN> restore spfile from ‘/u01/app/oracle/fast_recovery_area/ORCL/autobackup/2015_10_12/o1_mf_s_892911216_c1pp7o9p_.bkp‘;

停掉伪实例，还原原来的参数文件名，原来是ORACLE_SID=orcl

RMAN备份数据库与恢复数据库(整库)的相关文章

ORACLE中采用rman备份异机恢复数据库详细过程

场景:        有一个生产库的用户下面所有的表都不见了,怀疑人为被删除了,现在需要用备份去恢复下,找出原来的表,线上是oracle dataguard环境,有全库备份文件,准备去测试库恢复一下. 1,从生产库上copy好全备份文件恢复数据库需要准备的文件:rman完整备份(包括数据文件.日志文件.控制文件.参数文件),记录源数据库的DBID 安装的测试数据库ORACLE数据库软件并创建跟源数据库同名和数据库SID并修改数据库DBID跟源数据库DBID一样,创建跟源数据库服务器相同的数据文件

使用rman备份异机恢复数据库

一.RMAN备份源库注意点: 最好保留rman备份日志 $rman target / log=backup.log RMAN>run { allocate channel t1 type disk; allocate channel t2 type disk; allocate channel t3 type disk; allocate channel t4 type disk; backup format '<give location of backup/%U>' filesper

oracle数据库rman备份计划及恢复

1.rman完全恢复的前提条件:历史的datafile,controlfile和spfile备份,加上完整的archivelog和完好的redolog. 2.rman备份脚本: a.RMAN 0级备份命令: run{ allocate channel c1 type disk; allocate channel c2 type disk; allocate channel c3 type disk; backup incremental level 0 tag 'level0' format "

RMAN - 备份异机恢复

OS: Oracle Linux Server release 5.7 DB: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production ① RMAN异机恢复的时候,db_name必须相同.如果想要改别的实例命,可以在RMAN恢复成功后,用 nid 命令修改. ② 恢复路径与源库不相同,在restore时用set指定新位置,并用switch logfile all 将信息更新到controlfile文

Oracle RMAN 备份控制文件/恢复控制文件

--备份控制文件 rman target / RMAN> startup RMAN> configure controlfile autobackup on; --启动自动备份 RMAN> show CONTROLFILE AUTOBACKUP;  --显示是否自动备份控制文件 RMAN> configure controlfile autobackup format for device type disk to '/backup/%F'; --设置控制文件备份路径 RMAN&g

使用rman异地恢复数据库试验（RAC恢复到单实例数据库）

前言 rman在实际应用中用到的不多,很多时候一个项目开始设置好备份策略,后续基本上都用不到了,除非数据库出现异常,可以说,rman是一个不常用但是却非常重要的技能,但是又非常容易忘记.为了不在关键时刻掉链子,做了一个rman异地恢复数据库的试验. 试验环境介绍 操作系统 数据库版本 RAC? 源系统 CentOS 6.3 x64 11.2.0.4 2节点 目标系统 RedHat 6.4 x64 11.2.0.4 单节点 Rman备份: 0级数据库全备 操作步骤 将rman备份文件从源库上面拷贝

利用SHELL脚本来验证Oracle数据库RMAN备份集的有效性

利用SHELL脚本来验证Oracle数据库RMAN备份集的有效性 作者:赵全文  网名:guestart 我们生产环境的Oracle数据库都做了RMAN备份,是采用了一周的RMAN备份保留策略:除了使用RMAN备份以外,我们还使用了爱数(Eisoo)备份软件来进行备份,可以说是做到了有备无患.可是,如果有一天,Oracle数据库由于主机层面硬件原因或是数据库层面的原因不能对外提供高可用服务的时候,假设数据丢了一大部分,我们只有用RMAN备份来进行恢复,再如果发现,RMAN备份失效了,那就往地缝里

rman 备份并异机恢复

1.RMAN 备份脚本 RUN { CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS; CONFIGURE CONTROLFILE AUTOBACKUP ON; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO "/backup/ZGW_Controlfile_%F"; ALLOCATE CHANNEL CH1 DEVICE TYPE DISK;

7.2 使用恢复数据库恢复数据

恢复数据库 (RDB) 一种特殊的邮箱数据库,通过它您可以装入还原的邮箱数据库,并可以在恢复操作中从还原的数据库提取数据. 您可以使用 New-MailboxRestoreRequest cmdlet 从 RDB 提取数据. 提取后,可将数据导出到一个文件夹或者合并到一个现有邮箱中. RDB 使您能够从备份或数据库副本中恢复数据,而不会干扰用户对当前数据的访问. Microsoft Exchange Server 2013 支持将数据直接还原到恢复数据库. 安装恢复的数据作为恢复数据库使管理员能
