Oracle 11g 中恢复管理器RMAN介绍
2024-05-16 15:37:54
这是我平时摘录的笔记，从管理艺术那本书上摘录出来的，放到这里
RMAN 可在数据库服务器的帮助下从数据库内备份数据文件，可构造数据文件映像副本、控制文件和控制文件映像、对当日志 SPFILE 和RMAN备份片的备份，建议使用RMAN界面备份数据库
RMAN好处：
1 增量备份
2 可联机修补数据文件的部分讹误数据块，不需要从备份文件复原文件 称为介质恢复
3 人为错误最小化
4 一条简单命令 BACKUP DATABASE即可
5 RMAN新的快比较特性允许在备份中跳过数据文件中从未使用的数据块备份，节省存储空间和备份时间
6 通过RMAN容易进行自动化备份和恢复
7 在备份和恢复中可 进行错误检查
8 RMAN在联机备份中不生成重做信息，降低联机备份开销
9 二进制压缩特性降低保存磁盘上备份的大小
10 使用恢复目录catelog可直接在其中的存储备份和恢复脚本
11 RMAN 可执行模拟备份和恢复
12 允许进行映像复制，类似操作系统的文件备份
13 RMAN与第三方介质管理产品集成，使磁带备份极为容易
14 RMAN与OEM集成的很好
15 可利用RMAN功能方便克隆数据库和维护备用数据库RMAN执行其备份和恢复功能的条目列表
目标数据库:RMAN需要备份的数据库
RMAN信息库:RMAN关于备份。归档重做日志及其拥有的活动的元数据，每个数据库控制文件为RMAN信息 库主存储
恢复目录模式:拥有RMAN备份和恢复元数据的数据库中数据库模式
RMAN客户机:用户通过RMAN客户机管理RMAN操作
RMAN可执行程序:管理所有备份和恢复操作的实际程序
服务器进程:RMAN可执行程序与目标数据库通信的后台进程，在备份和恢复中完成读写磁盘和磁带设备的实际工作注:在使用RMAN中，有三个实体是可选的：闪回恢复区 恢复目录数据库和介质管理软件
RMAN信息库和恢复目录
RMAN信息库包含的条目信息:
数据文件备份集合副本
归档重做日志副本和备份集
表空间和数据文件信息
存储脚本和RMAN配置设置RMAN的信息首先写入到控制文件，然后在写到恢复目录(如果存在)
在创建新备份集时，可在V$BACKUP_SET视图看到响应的信息，也可以在恢复目录视图RC_BACUP_SET中看到相同的信息

有一些RMAN命令可在仅使用恢复目录时使用。还可以在仅使用恢复目录时使用RMAN存储脚本。如果使用控制文件，要冒某些历史数据被覆盖的风险，但恢复目录将保障这些数据的安全，这是因为控制文件与备份有关的活动分配的空间有限，从而恢复目录有更多的空间存储备份历史。系统中的一个恢复目录可对多个Oracle数据库执行备份、复原和恢复活动.Oracle建议使用专门的数据库来运行恢复目录

RMAN脚本，提供了两种脚本：
1 存储脚本：保存在RMAN恢复目录中
2 文本脚本：保存在普通的文本文件中
RMAN术语：
1 备份片
一个操作系统文件 包含一个数据文件、一个控制文件或数个归档重做日志文件的备份，备份信息以RMAN专门格式存储
2 备份集
逻辑结构，由一个或多个RMAN备份片组成。可在磁盘或磁带上创建备份集，备份集时仅RMAN能识别的适当格式的一个文件或一组文件，只有RMAN才能使用备份集恢复数据库
3 映像文件
类似UNIX中用cp命令或DOC中用COPY命令所做的操作系统文件备份，可制作数据文件、控制文件和归档重做日志文件的映像副本。RMAN映像副本只能做到磁盘，不能做到磁带中
4 代理副本
还可以执行一种叫代理副本的特殊备份，其中介质管理器得到复制进程的控制权，对磁盘不能使用代理副本。
5 通道
RMAN必须使用对服务器的某种连接，以执行备份和恢复任务，通道就代表这种连接。通道指定用于备份或恢复的设备、磁盘或磁带。可预先配置通道。也可手动指定
RMAN还可以使用利用非RMAN操作系统应用程序做的副本，这些类型的副本称为用户管理的副本或操作系统副本
RMAN允许对每个备份使用一个标记tag,以便容易地识别出相应的备份
标记全数据库备份
SQL>BACKUP TAG 'weekly_full_db_bkup' DATABASE;备份命令还可以使员工FORMAT来指定备份片和副本的位置和名字们使用替换变量来生成唯一的文件名
SQL>BACKUP FORMAT='AL_%d/%t/%s/%p' ARCHIVELOG LIKE '%arc_dest%';RMAN命令

RMAN备份逻辑检查
在备份过程中使用关键字LOGICAL让RMAN对备份文件进行逻辑检查。
增量备份
增量备份的级别为0或者1，
0：像完整备份一样复制所有的数据库，并且作为后续增量备份的基础
1：首先有一个基本的级别为0的备份
提供了两种类型
差异备份：备份最近级别为1或级别为0的增量备份后更改的所有块
累计备份：备份最近级别为0的增量备份后更改的所有块
开始一个级别为0的备份，

增量备份文件大小取决于更改过的块的数据和增量级别.累积备份比差异备份大，因为他们复制相同级别备份所复制的数据。具有减少恢复时间的有几点，如果空间不是个问题，建议累积备份
结合增量备份提出的备份策略
星期天 执行一个级别为0的增量备份 星期一到星期六，执行级别为1的差异增量备份 下一周重复这个循环
在这个策略中，如果需要星期四晚上恢复数据，应该讲星期一到星期三的增量备份应用到星期天的级别为0的备份
考虑一个累积备份替代策略
星期天，执行级别为0的增量备份 星期一到星期六，执行级别为1的累积增量备份 下一周重复这个循环
在此情况下，每天的级别为1的累积备份将备份自星期天备份以来更改的所有块。因此，如果星期四需要恢复，只需要将头天晚上的为一个累积备份应用到星期天的级别为0的增量备份即可

备份删除
使用DELETE命令来删除RMAN所做的物理备份，DELETE命令删除物理备份，更新控制文件记录及支出备份已删除，而且此命令还从恢复目录中删除备份的记录，可删除备份集。归档重做日志和数据文件副本
通常应该使用RMAN的DELETE命令而不是操作系统的删除命令来删除RMAN备份，否则，RMAN的信息库将会包含不在可用的备份记录
删除RMAN已经至少两次备份到磁盘的所有归档重做日志

DELETE OBSOLETE命令将删除所有不在需要的备份，可以定期执行DELETE OBSOLETE删除所有废弃的备份。
DELETE EXPIRED命令删除国企的备份的恢复目录记录，并将它们标记成DELETED。可以先执行CROSSCHECK命令，RMAN标记它不能找到的备份为国企。一个备份过期代表RMAN不能找到该备份文件，可是使用DELETE EXPIRED命令从控制文件和恢复目录删除这些文件的记录
报告命令
RMAN提供了几个非常有用的报告命令，他们允许检查备份和恢复过程。可查询RMAN，有哪些文件需要备份，哪些文件废弃，从而可以删除
REPORT SCHEMA命令列出目标数据库的所有数据文件
REPORT OBSOLETE命令显示被锁选择的保留策略认定为废弃的所有备份

1 备份保留的策略
备份保留策略指示RMAN合适考虑废弃数据文件和日志文件的备份，请注意，当指定RMAN在一定的时间后考虑废弃某个备份文件时，RMAN只标记该文件为废弃，并不删除它
默认的REDUNDANCY选项和RETENTION WINDOW选项
RMAN> CONFIGURE RETENTION POLICY TO REDUNDANCY 2;using target database control file instead of recovery catalog
new RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
new RMAN configuration parameters are successfully stored
如果每天备份数据文件，RMAN只保留每个数据库文件的两个备份，RMAN将保留恢复两天的数据文件备份需要的所有重做日志。任何早于两天的备份被认为是废弃的。
如果希望之星一个PITR到某个比最近备份更早的时间。归档的备份是有用的。如果当前备份不能使用，还有一个备选的备份集可用
RECOVERY WINDOW选项
如果数据库收到介质故障的影响，则从过去的某个时间开始恢复，RMAN保留数据文件和日志文件比恢复时间窗造一个备份的所欲备份，例如，如果恢复时间窗为7天，RMAN将保留7天以前最后做的备份开始的所有备份，如下设置恢复时间窗
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;using target database control file instead of recovery catalog
old RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO REDUNDANCY 2;
new RMAN configuration parameters:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 14 DAYS;
new RMAN configuration parameters are successfully stored
默认设备类型
备份的默认设备为磁盘，RMAN将自动备份到服务器上文件系统中，如果希望备份到磁盘中，需要配置默认设备类型为sbt(所有磁带目标都为sbt)
SQL>CONFIGURE DEFUALT DEVICE TYPE TO sbt;如果希望从默认设备切换到磁盘
SQL>CONFIGURE DEFAULT DEVICE TYPE TO DISK； 备份优化
BACKUP OPTIMIZATION保证。如果RMAN已经备份了某个文件的相同版本，则不会进行该文件的备份。
SQL>CONFIGURE BACKUP OPTIMIZATION ON;控制文件参数
有几个设计控制文件备份的参数，
控制文件自动备份
如果将CONFIGURE AUTOBACKUP 设置成ON，则每次进行数据文件备份时，控制文件也与SPFILE一起自动备份。
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored
现在，如果使用任何备份命令，控制文件和SPFILE两者都会自动备份
