recover和restore的区别: restore just copy the physical file, recover will consistent the database. restore 是还原,文件级的恢复.就是物理文件还原.recover 是恢复,数据级的恢复.逻辑上恢复,比如应用归档日志.重做日志,全部同步,保持一致. 用我自己的土话讲就是,用restore先把备份文件拷贝到数据库目录下进行替换,再用recover经过一些处理,数据库就恢复正常了. 1.restore 命…

restore 是还原物理文件 recover 是用日志恢复到一致 用了RMAN备份后就必须要用restore还原,然后才用recover恢复 restore——还原,与backup相对,从备份读出恢复备份的数据. recover——恢复,把restore回来的数据经过一番处理变成正常数据. 如果restore,而不recover的话,数据库是打不开的!因为各文件都不同步 积累型(COMULATIVE ERPORT):备份上一次积累型备份所改变的数据: 增量型(INCREAMENTAL EXPO…

1.备份:物理备份时文件层次的备份,逻辑备份时数据层次的备份,物理备份为主,逻辑备份作为补充.物理备份分为用户管理备份和RMAN备份,前者使用SQL命令和OS的cp命令进行文件备份,后者使用RMAN工具份.Undo Segment:修改记录过程中,记录修改前的状态会被记录到Undo Segment中,这条记录叫作前镜像(before images).当需要撤销修改比如执行rollback时,就用这条前镜像覆盖现有记录.对于Insert操作,前镜像就是一个空记录,对于Update,Delete操作…

第二章. 了解备份的重要性 可以说,从计算机系统出世的那天起,就有了备份这个概念,计算机以其强大的速度处理能力,取代了很多人为的工作,但是,往往很多时候,它又是那么弱不禁风,主板上的芯片.主板电路.内存.电源等任何一项不能正常工作,都会导致计算机系统不能正常工作.当然,这些损坏可以修复,不会导致应用和数据的损坏.但是,如果计算机的硬盘损坏,将会导致数据丢失,此时必须用备份恢复数据. 其实,在我们的现实世界中,已经就存在很多备份策略,如RAID技术,双机热备,集群技术发展的不就是计算机系统的备份和…

Oracle RAC的优势在于利用多个节点(数据库实例)组成一个数据库,这样在保证了数据库高可用性的情况下更充分的利用了多个主机的性能,而且可以通过增加节点进行性能的扩展.实现Oracle RAC需要解决的关键问题就是多节点进行数据访问时如何保证数据的一致性,Oracle是通过各节点间的私有连接进行内存融合(cache fusion)来保证各节点数据访问的一致性.用一个例子来解释一下内存融合的过程,在存在A.B两个节点的RAC环境中,当A节点使用DML语句(如Update)对一个数据块中的数据进…
