rman恢复数据库

      近期由于公司需求把生产环境数据导入测试环境进行业务测试，而生产数据库管理员使用rman 进行全备份。所以在测试环境我也得使用rman进行恢复.操作步骤如下所示：

 1、首先手动创建一个参数文件，只要能启动实例就行，然后恢复备份的参数文件：

1）启动数据库到nomount状态
RMAN> startup nomount;

Oracle instance started

Total System Global Area    1610612736 bytes

Fixed Size                     2068296 bytes
Variable Size                385876152 bytes
Database Buffers            1207959552 bytes
Redo Buffers                  14708736 bytes

2）启动rman并恢复参数文件，但报错
RMAN> restore spfile from '/home/orarch_ecdsdb2/20121218/spfile.bk';

Starting restore at 07-JAN-13
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=541 devtype=DISK

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 01/07/2013 11:17:48
RMAN-06564: must use the TO clause when the instance is started with SPFILE

 

3）修改了命令继续执行发现报错如下：
RMAN> restore spfile to '/home/oracle/ora10/dbs/spfileecdsdb.ora' from '/home/orarch_ecdsdb2/20121218/spfile.bk';

Starting restore at 07-JAN-13
using channel ORA_DISK_1

channel ORA_DISK_1: autobackup found: /home/orarch_ecdsdb2/20121218/spfile.bk
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 01/07/2013 12:20:38
ORA-32011: cannot restore SPFILE to location already being used by the instance
此错误时因为我数据库已经启动到了nomout状态用spfileecdsdb.ora文件所以生成不了，于是我就先生成spfileecds.ora'

4）生成spfileecds.ora
RMAN> restore spfile to '/home/oracle/ora10/dbs/spfileecds.ora' from '/home/orarch_ecdsdb2/20121218/spfile.bk';

Starting restore at 07-JAN-13
using channel ORA_DISK_1

channel ORA_DISK_1: autobackup found: /home/orarch_ecdsdb2/20121218/spfile.bk
channel ORA_DISK_1: SPFILE restore from autobackup complete
Finished restore at 07-JAN-13

RMAN>

5）利用此文件再生成pfile_ecdsdb.ora文件
$ export ORACLE_SID=ecdsdb（可根据需求自己进行设置）
$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.5.0 - Production on Mon Jan 7 12:23:15 2013

SQL> shutdown immediate;
ORA-01507: database not mounted

ORACLE instance shut down.

 

SQL> CREATE PFILE='/home/oracle/ora10/dbs/pfile_ecdsdb.ora' from spfile='/home/oracle/ora10/dbs/spfileecds.ora'
  2  ;

File created.

SQL>

6）按实际情况修改pfile_ecdsdb.ora文件，其中要注意control_files、audit_file_dest、background_dump_dest、core_dump_dest等四个文件的路径于你需要恢复的数据库路径一样，并且数据库实例名称要改为利用export ORACLE_SID=ecdsdb设置的ecdsdb

7）利用pfile_ecdsdb.ora生成spfileecds.ora文件
SQL> create spfile  From Pfile='/home/oracle/ora10/dbs/pfile_ecdsdb.ora'
  2  ;

File created.

2、恢复控制文件

1）启动数据库到nomount状态
SQL> startup nomount
ORACLE instance started.

Total System Global Area 2147483648 bytes
Fixed Size                  2069320 bytes
Variable Size             486542520 bytes
Database Buffers         1644167168 bytes
Redo Buffers               14704640 bytes

2）恢复控制文件
MAN> RESTORE CONTROLFILE FROM '/home/orarch_ecdsdb2/20121218/ctl.bk';

Starting restore at 07-JAN-13
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 01/07/2013 13:01:13
ORA-03135: connection lost contact

RMAN> quit
报如上错误信息说明是连接已经断了，所以要重新登录rman

Recovery Manager complete.

3）再一次执行恢复命令
$ rman target /

3、修复数据库
1）执行恢复命令
RMAN> RESTORE DATABASE;

Starting restore at 07-JAN-13

报如上错误，说明控制文件中记录了目标数据库的数据库文件路径和本地的/home/oracle/oradata/ecdsdb/不同，所以必须重新指向数据文件的位置如下操作。

 

 

2）执行脚本命令重新恢复数据库
RMAN> run{
2> set newname for datafile 1 to '/home/oracle/oradata/ecdsdb/system_01_4g';
3>    set newname for datafile 2 to '/home/oracle/oradata/ecdsdb/undotbs1_01_10g';
4>    set newname for datafile 4 to '/home/oracle/oradata/ecdsdb/user_01_512m';
