12c中的RECOVER TABLE

在RMAN中提供了表级别恢复（RECOVER TABLE）。在Oracle 12c中，在发生drop或truncate的情况下，可以从RMAN备份种将一个特定的表或分区恢复到某个时间点、SCN或归档序列号，并且可以有下面的选择：

l 使用REMAP选项将表恢复为一个新表或者分区中，也可以恢复到其他用户中。

l 只生成一个需要被恢复表的expdp格式的dump文件，选择后期再进行恢复。

Oracle 12c的Recover Table新特性是利用创建辅助临时实例加数据泵工具来实现的。通常在进行Recover Table之前应该准备好两个目录（AUXILIARY DESTINATION和DATAPUMP DESTINATION），AUXILIARY DESTINATION用来临时存放辅助实例的数据文件，DATAPUMP DESTINATION用来临时存放数据泵导出的文件。

只要之前创建了RMAN备份，那么就可以根据指定的的时间来进行表级和表分区级的恢复操作，而且不影响其他的数据库对象。RMAN的表级和表分区级恢复可以使用在如下场景：

①　在恢复小表或数据库中的某几张表时，但发现使用Restore Database或Tablespace的代价很高而且效率很低。也可以使用TSPITR（表空间基于时间点的恢复）的方法，但该方法效率很低，因为需要移动表空间中的所有对象。

②　恢复有逻辑损坏或者被删除的表。

③　Flashback Table不可用，例如Undo数据已经被覆盖的情况。

④　DDL操作后需要恢复数据。Flashback Table不支持表结构发生改变后的回退，例如TRUNCATE TABLE。

RMAN从备份中自动处理恢复表或者表分区时会执行如下步骤：

1.判断哪些备份包含需要恢复的表或表分区，然后根据指定的时间来进行恢复。

2.判断目标主机上是否有足够的空间来创建auxiliary instance，该实例用于处理表或分区的恢复。如果需要的空间不足，那么RMAN会报错并退出恢复操作。

3.创建auxiliary database，并根据指定的时间来恢复指定的表或表分区到auxiliary database中。辅助数据库的数据文件位置可以在命令中指定。

4.创建包含恢复表或表分区的数据泵文件（expdp dump file）。数据泵的名称和位置也可以在命令中指定。

5.（可选操作）将上一步生产的数据泵文件导入到目标实例中。当然也可以选择不导入，如果选择不导入就必须使用impdp手工导入。

6.（可选操作）在目标数据库中rename恢复表或表分区。

关于RECOVER TABLE需要注意的几个问题：

l 目标数据库必须被置于读写模式。

l 目标数据库必须被置于归档模式。

l 如果要恢复表或者分区，你必须拥有这些表或者分区存在后的时间的备份。

l 想要恢复单个表分区，COMPATIBLE初始化参数所在的目标库必须设置为11.1.0或以上。

l SYS用户下的表或分区无法恢复。

l 存储于SYSAUX和SYSTEM表空间下的表和分区无法恢复。

l Standby数据库上的表或表分区不能进行恢复。

l 在使用REMAP的情况下，有NOT NULL 约束的表不能进行恢复。

l 确保对于辅助数据库在文件系统下有足够的可用空间，同时对数据泵文件也有同样保证。

l 必须要存在一份完整的数据库备份，至少要有SYSTEM、UNDO、SYSAUX和表所在表空间相关的备份。表误操作可以在数据库备份之前也可以在数据库备份之后。如果恢复的表在PDB中，那么需要备份Root Container的SYSTEM，SYSAUX、UNDO和PDB的SYSTEM、SYSAUX以及包含了要恢复的表的表空间。

l 在存在CDB的情况下，在执行RECOVER TABLE时必须使用sys用户登录，而不能使用“rman target /”进行登录。

在执行“RECOVER TABLE”命令时，可以根据需要在以下三种级别指定时间：

（1）SCN号

（2）Sequence number（日志序列号）

（3）Time：根据NLS_LANG和NLS_DATE_FORMAT环境变量中的格式来指定时间，也可以用SYSDATE，比如"SYSDATE-30"、"to_date('2018-04-09:13:51:48','yyyy-mm-dd hh24:mi:ss')"

“RECOVER TABLE”命令的一般格式为：

RMAN> connect target "username/password as SYSBACKUP"; 

RMAN> RECOVER TABLE username.tablename UNTIL TIME 'TIMESTAMP…' 

AUXILIARY DESTINATION '/u01/tablerecovery' 

DATAPUMP DESTINATION '/u01/dpump' 

DUMP FILE 'tablename.dmp' 

NOTABLEIMPORT -- this option avoids importing the table automatically.(此选项避免自动导入表) 

REMAP TABLE 'username.tablename': 'username.new_table_name'; -- can rename table with this option.(此选项可以对表重命名)

RMAN> connect target "username/password as SYSBACKUP";

RMAN> RECOVER TABLE username.tablename UNTIL TIME 'TIMESTAMP…'

AUXILIARY DESTINATION '/u01/tablerecovery'

DATAPUMP DESTINATION '/u01/dpump'

DUMP FILE 'tablename.dmp'

NOTABLEIMPORT -- this option avoids importing the table automatically.(此选项避免自动导入表)

REMAP TABLE 'username.tablename': 'username.new_table_name'; -- can rename table with this option.(此选项可以对表重命名)

示例1：在PDB中恢复表HR.PDB_EMP,恢复后的表命名为EMP_RECVR

RECOVER TABLE HR.PDB_EMP OF PLUGGABLE DATABASE HR_PDB

UNTIL TIME 'SYSDATE-4'

AUXILIARY DESTINATION '/tmp/backups'

REMAP TABLE 'HR'.'PDB_EMP':'EMP_RECVR';

RECOVER TABLE DB12C.T

UNTIL SCN 1932621

AUXILIARY DESTINATION '/tmp/oracle/recover'

REMAP TABLE 'DB12C'.'T':'T_HISTORY_20130717';

RECOVER TABLE LHR.TEST_RT

UNTIL TIME "to_date('2018-04-09:13:51:48','yyyy-mm-dd hh24:mi:ss')"

AUXILIARY DESTINATION '/tmp'

REMAP TABLE 'LHR'.'TEST_RT':'TEST_RT_LHR';

RECOVER TABLE HR.DEPARTMENTS, SH.CHANNELS

UNTIL TIME 'SYSDATE – 1'

AUXILIARY DESTINATION '/tmp/auxdest'

REMAP TABLE hr.departments:example.new_departments, sh.channels:example.new_channels;

RECOVER TABLE HR.PDB_EMP OF PLUGGABLE DATABASE HR_PDB

UNTIL TIME 'SYSDATE-4'

AUXILIARY DESTINATION '/tmp/backups'

REMAP TABLE 'HR'.'PDB_EMP':'EMP_RECVR';

RECOVER TABLE DB12C.T

UNTIL SCN 1932621

AUXILIARY DESTINATION '/tmp/oracle/recover'

REMAP TABLE 'DB12C'.'T':'T_HISTORY_20130717';

RECOVER TABLE LHR.TEST_RT

UNTIL TIME "to_date('2018-04-09:13:51:48','yyyy-mm-dd hh24:mi:ss')"

AUXILIARY DESTINATION '/tmp'

REMAP TABLE 'LHR'.'TEST_RT':'TEST_RT_LHR';

RECOVER TABLE HR.DEPARTMENTS, SH.CHANNELS

UNTIL TIME 'SYSDATE – 1'

AUXILIARY DESTINATION '/tmp/auxdest'

REMAP TABLE hr.departments:example.new_departments, sh.channels:example.new_channels;

示例2：从RMAN备份中恢复表SCOTT.EMP,SCOTT.DEPT,并以数据泵格式导出emp_dept_exp_dump.dat，并不进行表的导入

RECOVER TABLE SCOTT.EMP, SCOTT.DEPT

  UNTIL TIME 'SYSDATE-1'

  AUXILIARY DESTINATION '/tmp/oracle/recover'

  DATAPUMP DESTINATION '/tmp/recover/dumpfiles'

  DUMP FILE 'emp_dept_exp_dump.dat'

  NOTABLEIMPORT;

RECOVER TABLE SCOTT.EMP, SCOTT.DEPT

UNTIL TIME 'SYSDATE-1'

AUXILIARY DESTINATION '/tmp/oracle/recover'

DATAPUMP DESTINATION '/tmp/recover/dumpfiles'

DUMP FILE 'emp_dept_exp_dump.dat'

NOTABLEIMPORT;

示例3：恢复表的两个分区，恢复后表分区重新命名并且放置于SALES_PRE_2000_TS表空间

RECOVER TABLE SH.SALES:SALES_1998, SH.SALES:SALES_1999

  UNTIL SEQUENCE 354

  AUXILIARY DESTINATION '/tmp/oracle/recover'

  REMAP TABLE 'SH'.'SALES':'SALES_1998':'HISTORIC_SALES_1998',

       'SH'.'SALES':'SALES_1999':'HISTORIC_SALES_1999'

  REMAP TABLESPACE 'SALES_TS':'SALES_PRE_2000_TS';

RECOVER TABLE SH.SALES:SALES_1998, SH.SALES:SALES_1999

UNTIL SEQUENCE 354

AUXILIARY DESTINATION '/tmp/oracle/recover'

REMAP TABLE 'SH'.'SALES':'SALES_1998':'HISTORIC_SALES_1998',

'SH'.'SALES':'SALES_1999':'HISTORIC_SALES_1999'

REMAP TABLESPACE 'SALES_TS':'SALES_PRE_2000_TS';

Oracle 12c 新特性：RMAN Recover Table 详解

1. Recover Table 和 Table Partitions概述

Oracle 从12c开始支持在RMAN 中进行表级的恢复操作，即对单表进行recover。官方文档链接如下：

http://docs.oracle.com/database/122/BRADV/rman-recovering-tables-partitions.htm

RMAN的表级和表分区级恢复可以使用在如下场景：

\1. 恢复小表时。也可以使用TSPITR 的方法，但该方法效率很低,因为需要移动表空间中的所有对象。

\2. 恢复有逻辑损坏或者被删除的表。

\3. Flashback Table 不可用，比如undo 数据已经被覆盖。

\4. DDL 操作后需要恢复数据。Flashback Table 不支持表结构发生改变后的回退。比如truncate table。

只要之前创建了RMAN 备份，就可以根据指定的的时间来进行表级和表分区级的恢复操作，而且不影响其他的数据库对象。

可以根据在以下三种级别指定时间：

（1） SCN

（2） Sequence number

（3） Time：根据 NLS_LANG 和 NLS_DATE_FORMAT 环境变量中的格式来指定时间，也可以用SYSDATE，比如 SYSDATE-30.

为了恢复表或者表分区，需要备份undo，SYSTEM,SYSAUX和包含表或者表分区的表空间。

如果恢复的表在PDB中，那么需要备份如下内容：

\1. Root的SYSTEM，SYSAUX 和undo 表空间，SEED，以及包含表的PDB。

\2. 包含表或分区的表空间

当然恢复表或者表分区也有限制条件，以下情况不能使用：

\1. SYS 用户的表或表分区不能进行恢复

\2. SYSTEM 和SYSAUX 表空间中的表或表分区不能进行恢复。

\3. Standby 数据库上的表或表分区不能进行恢复。

\4. 在使用REMAP 的情况下，有NOT NULL 约束的表不能进行恢复。

RMAN从备份中自动处理恢复表或者表分区时会执行如下步骤：

1.判断哪些备份包含需要恢复的表或表分区，然后根据指定的时间来进行恢复。

2.判断目标主机上是否有足够的空间来创建auxiliary instance，该实例用于处理表或分区的恢复。如果需要的空间不足，那么RMAN 会报错并退出恢复操作。

3.创建auxiliary database，并根据指定的时间来恢复指定的表或表分区到auxiliary database中。辅助数据库的数据文件位置可以在命令中指定。

4.创建包含恢复表或表分区的数据泵文件（expdp dump file）。数据泵的名称和位置也可以在命令中指定。

\5. （可选操作）将上一步生产的数据泵文件导入到目标实例中。当然也可以选择不导入，如果选择不导入就必须使用impdp 手工导入。

\6. （可选操作）在目标数据库中rename 恢复表或表分区。

2 PDB操作示例

2.1 准备测试环境

因为特性不支持系统用户和表，所以需要先创建独立的用户和表空间：

2.2 RMAN 备份CDB

--使用如下命令备份CDB的组建：ROOT,SEED,PDBS：

RMAN> backup database plus archivelog;

具体过程省略，第一小节已有说明，在PDB 中必须备份ROOT,SEED,和所有的PDBS.

2.3 恢复数据

现在drop cndba 表，然后执行恢复操作：

SQL> conn lotus/lotus@dave
Connected.
SQL> select to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual;

TO_CHAR(SYSDATE,'YY
-------------------
2017-04-17 10:20:49

SQL> drop table cndba;

SQL> conn lotus/lotus@dave

Connected.

SQL> select to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from dual;

TO_CHAR(SYSDATE,'YY

-------------------

2017-04-17 10:20:49

SQL> drop table cndba;

注意这里只能是drop，truncate不能recover。如果是truncate，那么就不能执行导入操作。

注意在链接RMAN 时需要连接到root，并且具有SYSDBA 或 SYSBACKUP 权限。

可以使用rman target sys 或 rman target /(The connection is established as the SYS user with SYSDBA privilege)

[oracle@www.cndba.cn cndba]$ mkdir -p /tmp/oracle/recover
[oracle@www.cndba.cn cndba]$ mkdir -p /tmp/recover/dumpfiles

1 2	[oracle@www.cndba.cn cndba]$ mkdir -p /tmp/oracle/recover [oracle@www.cndba.cn cndba]$ mkdir -p /tmp/recover/dumpfiles

恢复过程:还原system,undo,sysaux表空间,然后read only数据库,然后重启数据库还原表所在表空间,然后expdp导出表,根据需要决定是否导入表到原PDB数据库中，最后删除辅助数据库。整个过程对原PDB没有影响。

恢复命令如下：

recover table lotus.cndba of pluggable database dave
 until time "to_date('2017-04-17 10:20:49','yyyy-mm-dd hh24:mi:ss')"
 auxiliary destination '/tmp/oracle/recover'
datapump destination '/tmp/recover/dumpfiles'
 dump file 'www.cndba.cn.dat';

recover table lotus.cndba of pluggable database dave

until time "to_date('2017-04-17 10:20:49','yyyy-mm-dd hh24:mi:ss')"

auxiliary destination '/tmp/oracle/recover'

datapump destination '/tmp/recover/dumpfiles'

dump file 'www.cndba.cn.dat';

大致过程：

Creating automatic instance, with SID='ajrg' -----这里开始创建auxiliary instance

Starting restore at 17-APR-17 -----先restore database

Starting recover at 17-APR-17 ----再recover

# create directory for datapump import -----使用数据泵导出相关数据

3 注意事项

3.1 说明1：PDB操作恢复的数据还在原PDB中生成

上面的示例是在PDB中演示的。操作对象是单表，实际上对分区表中的单个分区也可以进行类似操作。

SQL> show con_name

CON_NAME
------------------------------
DAVE
SQL> select count(1) from cndba;

 COUNT(1)
----------
 72623

恢复的表还在原PDB中，中间产生的辅助数据库会在操作结束后删除。

SQL> show con_name

CON_NAME

------------------------------

DAVE

SQL> select count(1) from cndba;

COUNT(1)

----------

72623

恢复的表还在原PDB中，中间产生的辅助数据库会在操作结束后删除。

3.2 说明2: RMAN-05112: table "LOTUS"."CNDBA" already exists

在PDB测试中 , 最开始的操作的时候，是对cndba表进行truncate 操作的。但是执行recover时报错。提示表已经存在，尝试remap，并未成功。后来drop 掉表后成功recovoer。

当然也使用导出，添加notableimport参数不执行导入操作，然后在手工处理。

3.3 说明3：ORA-01516: nonexistent log file 问题

第一次模拟的时候，recover 时报了数据文件不存在的问题。实际上这个数据文件是我自己创建的。后来换了个环境，重新备份后正常。推测之前其他的rman 备份导致的异常。

3.4 说明4：non-CDB与PDB的区别

官网文档里还有另外一种写法，就是不带PDB 名称的。在CDB架构中测试的时候，会一直报RMAN-05057的错误：

recover table "c##lotus2".cndba 
 until time "to_date('2017-04-17 11:03:49','yyyy-mm-dd hh24:mi:ss')"
 auxiliary destination '/tmp/oracle/recover'
datapump destination '/tmp/recover/dumpfiles'
 dump file 'www.cndba.cn.dat';

但尝试恢复一直报表不存在的错误：
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 04/17/2017 11:35:55
