Oracle 灾难恢复以及11g新特性恢复指导

分手后的思念是犯贱 2022-08-13 09:29 335阅读 0赞

实验： 数据库灾难恢复（数据文件、控制文件、参数文件、归档文件等丢失）

法一：利用冷备

法二：RMAN恢复及11g新特性(list/advise/repair failure,create spfile from memory)

1.配置catalog数据库

1）catalog目录库：创建大文件表空间、用户、授权

create  bigfile tablespace rc\_data datafile '/u01/app/oracle/oradata/ORCL/rc\_data.dbf' size 20m;

create user rc\_admin identified by oracle default tablespace rc\_data;

grant connect,resource,recovery\_catalog\_owner to rc\_admin;

2）创建catalog库  
RMAN> rman catalog [rc\_admin/oracle@ORCL][rc_admin_oracle_ORCL]

RMAN> create catalog;

3）注册catalog库（在target库中）

RMAN> rman target / catalog [ rc\_admin/oracle@ORCL][rc_admin_oracle_ORCL]

RMAN>register database;

4）配置target数据库

RMAN> rman target / catalog [ rc\_admin/oracle@ORCL][rc_admin_oracle_ORCL]

RMAN>configure retention policy to recovery window of 7 days;  
      --修改保留策略

RMAN>configure controlfile autobackup on;  
      --打开控制文件自动备份

RMAN>configure device type disk parallelism  4;  
      --开启并行备份，行度设置为4

2.备份target数据库

当所有文件丢失时，使用RMAN，应连接catalog库（catalog库中含有控制文件等）

\[oracle@jibo admin\]$ rman target / catalog [ rc\_admin/oracle@ORCL][rc_admin_oracle_ORCL]

Recovery Manager: Release 11.2.0.4.0 - Production on Thu Oct 16 10:19:55 2014

connected to target database: PROD (DBID=270879665)  
connected to recovery catalog database

RMAN> show all;

RMAN configuration parameters for database with db\_unique\_name PROD are:  
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;  
CONFIGURE BACKUP OPTIMIZATION OFF; \# default  
CONFIGURE DEFAULT DEVICE TYPE TO DISK; \# default  
CONFIGURE CONTROLFILE AUTOBACKUP ON;  
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; \# default  
CONFIGURE DEVICE TYPE DISK PARALLELISM 4 BACKUP TYPE TO BACKUPSET;  
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; \# default  
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; \# default  
CONFIGURE MAXSETSIZE TO UNLIMITED; \# default  
CONFIGURE ENCRYPTION FOR DATABASE OFF; \# default  
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; \# default  
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; \# default  
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; \# default  
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/dbhome\_1/dbs/snapcf\_PROD.f'; \# default

RMAN> backup database include current controlfile plus archivelog delete all input;  
     --全库备份加上归档日志文件

3.模拟灾难：

1）删除所有数据文件：  
[SYS@PROD>select][SYS_PROD_select] name from v$datafile;

NAME  
\--------------------------------------------------------------------------------  
/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_system\_b393xosc\_.dbf  
/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_sysaux\_b393xovt\_.dbf  
/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_undotbs1\_b393xq2d\_.dbf  
/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_users\_b393xqpm\_.dbf  
/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_example\_b393xp04\_.dbf  
/u01/app/oracle/oradata/PROD/datafile/tbs\_users1.dbf  
/u01/app/oracle/oradata/PROD/datafile/tbs\_users2.dbf  
/u01/app/oracle/oradata/PROD/datafile/pitr.dbf  
/u01/app/oracle/oradata/PROD/datafile/pitr\_ind.dbf  
/u01/app/oracle/oradata/PROD/arch\_tbs.dbf

10 rows selected.

[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/oradata/PROD/datafile/\*.dbf

[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/oradata/PROD/arch\_tbs.dbf

[SYS@PROD>desc][SYS_PROD_desc] v$controlfile;  
 Name                                      Null?    Type  
 ----------------------------------------- -------- ----------------------------  
 STATUS                                             VARCHAR2(7)  
 NAME                                               VARCHAR2(513)  
 IS\_RECOVERY\_DEST\_FILE                              VARCHAR2(3)  
 BLOCK\_SIZE                                         NUMBER  
 FILE\_SIZE\_BLKS                                     NUMBER

2）删除所有控制文件：  
[SYS@PROD>select][SYS_PROD_select] name from v$controlfile;

NAME  
\--------------------------------------------------------------------------------  
/u01/app/oracle/oradata/PROD/controlfile/o1\_mf\_b2255k12\_.ctl  
/u01/app/oracle/fast\_recovery\_area/PROD/controlfile/o1\_mf\_b2255kjo\_.ctl

[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/oradata/PROD/controlfile/o1\_mf\_b2255k12\_.ctl  
[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/fast\_recovery\_area/PROD/controlfile/o1\_mf\_b2255kjo\_.ctl

3）删除参数文件：  
[SYS@PROD>show][SYS_PROD_show] parameter spfile;

NAME                                 TYPE        VALUE  
\------------------------------------ ----------- ------------------------------  
spfile                               string      /u01/app/oracle/product/11.2.0  
                                                 /dbhome\_1/dbs/spfilePROD.ora  
[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/product/11.2.0/dbhome\_1/dbs/spfilePROD.ora

4）删除归档文件：  
desc v$archived\_log --归档文件  
[SYS@PROD>select][SYS_PROD_select] name from v$archived\_log;

NAME  
\--------------------------------------------------------------------------------  
/u01/app/oracle/fast\_recovery\_area/PROD/archivelog/2014\_10\_16/o1\_mf\_1\_7\_b3y4y1s8\_.arc

/u01/app/oracle/fast\_recovery\_area/PROD/archivelog/2014\_10\_16/o1\_mf\_1\_8\_b3y56mno

...

8 rows selected.

[SYS@PROD>!rm][SYS_PROD_rm] /u01/app/oracle/fast\_recovery\_area/PROD/archivelog/2014\_10\_16/\*;

alter system checkpoint;  
  --触发错误

5）退出重新进入：  
[SYS@PROD>stutdown][SYS_PROD_stutdown] immediate  
SP2-0734: unknown command beginning "stutdown i..." - rest of line ignored.  
[SYS@PROD>shutdown][SYS_PROD_shutdown] immediate  
ORA-01116: error in opening database file 2  
ORA-01110: data file 2: '/u01/app/oracle/oradata/PROD/datafile/o1\_mf\_sysaux\_b393xovt\_.dbf'  
ORA-27041: unable to open file  
Linux-x86\_64 Error: 2: No such file or directory  
Additional information: 3  
[SYS@PROD>shutdown][SYS_PROD_shutdown] abort  
ORACLE instance shut down.  
[SYS@PROD>startup][SYS_PROD_startup]  
ORA-01078: failure in processing system parameters  
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome\_1/dbs/initPROD.ora'  
  --报错

4.利用catalog恢复target数据库

1）在catalog库查看target数据库DBID

sqlplus rc\_admin/oracle

[RC\_ADMIN@ORCL>select][RC_ADMIN_ORCL_select] \* from rc\_database;

DB\_KEY  DBINC\_KEY       DBID NAME     RESETLOGS\_CHANGE\# RESETLOGS  
\---------- ---------- ---------- -------- ----------------- ---------  
       241        242 1385095721 ORCL                925702 03-SEP-14  
         1         61  270879665 PROD               1107625 08-OCT-14

2）连接catalog数据库  
\[oracle@jibo ~\]$ rman target / catalog [ rc\_admin/oracle@ORCL][rc_admin_oracle_ORCL]

Recovery Manager: Release 11.2.0.4.0 - Production on Thu Oct 16 14:08:59 2014

connected to target database (not started)  
connected to recovery catalog database  
    --可以连接，但数据库没有启动

3）设置dbid，并启动数据库到nomount状态  
RMAN> set dbid=270879665;

executing command: SET DBID  
database name is "PROD" and DBID is 270879665

RMAN> startup nomount;

startup failed: ORA-01078: failure in processing system parameters  
LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome\_1/dbs/initPROD.ora'

starting Oracle instance without parameter file for retrieval of spfile

Oracle instance started

Total System Global Area    1068937216 bytes

Fixed Size                     2260088 bytes  
Variable Size                281019272 bytes  
Database Buffers             780140544 bytes  
Redo Buffers                   5517312 bytes

4)还原参数文件和数据文件  
RMAN>restore spfile;

RMAN>restore controlfile;  
或者：  
RMAN>restore spfile from autobackup;  
RMAN>restore controlfile from autobackup;  
或者：  
RMAN>restore spfile from '/u01/app/oracle/fast\_recovery\_area/PROD/autobackup/2014\_10\_16/o1\_mf\_s\_861103939\_b3yh28ts\_.bkp';  
RMAN>restore controlfile from '/u01/app/oracle/...';  
  --如果Oracle无法找到自动备份文件，则需要手工制定该文件的具体位置

5）启动数据库到mount状态并使用11g数据库的新特性（list/advise/repair failure）  
RMAN> startup mount;

database is already started  
database mounted  
released channel: ORA\_DISK\_1  
released channel: ORA\_DISK\_2  
released channel: ORA\_DISK\_3  
released channel: ORA\_DISK\_4

新特性：  
list failure;  
   --如果list failure 没有输出结果，则需要我们手动恢复数据库；  
advise failure;  
   --如果advise failure 输出的最后，显示没有可用的自动修复选项，则同样需要我们手动恢复；  
repair failure;  
   --三条命令顺序不能改变

补充：  
 如果list failure没有输出结果，  
则可以尝试打开数据库，查看报错信息，然后进行相应的处理；  
eg：  
 alter database open;  
 alter database open resetlogs;  
 restore datafile 1;  
 list failure;  
 advise failure;  
 repair failure;

指令：  
RMAN>list failure;

RMAN>advise failure;

RMAN>repair failure;

具体执行过程：  
RMAN> list failure;
