1.查看我们创建的磁盘组

[oracle@std ~]$ export ORACLE_SID=+ASM

[oracle@std ~]$ sqlplus '/as sysdba'

Oracle Database 10g Enterprise Edition Release 10.2.0.4. - Production

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL> select name,total_mb,free_mb from v$asm_diskgroup;

2.启动数据库实例查看数据文件等

SQL> select * from v$dbfile;

3.对RDBMS做一个备份

4.修改RDBMS参数

SQL> alter system set db_recovery_file_dest_size=3g scope=both;

System altered.

SQL> alter system set db_recovery_file_dest='+FLA' scope=both;

System altered.

SQL> alter system set db_create_file_dest='+DATA' scope=both;  

System altered.

SQL> alter system set db_create_online_log_dest_1='+DATA' scope=spfile;

System altered.

5.迁移联机日志到ASM磁盘

SQL> select a.group#,a.status,b.member from v$log a,v$logfile b

    where a.group#=b.group#;

    GROUP# STATUS           MEMBER

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

          INACTIVE         /u02/app/oradata/ZDJS/redo03.log

          INACTIVE         /u02/app/oradata/ZDJS/redo02.log

          CURRENT          /u02/app/oradata/ZDJS/redo01.log

SQL> alter database add logfile member '+DATA','+FLA' to group ;

Database altered.

SQL> alter database add logfile member '+DATA','+FLA' to group ;

Database altered.

SQL> alter database add logfile member '+DATA','+FLA' to group ;

Database altered.

SQL> select a.group#,a.status,b.member from v$log a,v$logfile b

    where a.group#=b.group#;

    GROUP# STATUS           MEMBER

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

          INACTIVE         /u02/app/oradata/ZDJS/redo03.log

          INACTIVE         /u02/app/oradata/ZDJS/redo02.log

          CURRENT          /u02/app/oradata/ZDJS/redo01.log

          CURRENT          +DATA/zdjs/onlinelog/group_1.264.870617701

          CURRENT          +FLA/zdjs/onlinelog/group_1.256.870617713

          INACTIVE         +DATA/zdjs/onlinelog/group_2.265.870617759

          INACTIVE         +FLA/zdjs/onlinelog/group_2.257.870617769

          INACTIVE         +DATA/zdjs/onlinelog/group_3.266.870618057

          INACTIVE         +FLA/zdjs/onlinelog/group_3.258.870618067

 rows selected.

删除原来的状态为INACTIVE的联机日志，通过alter system switch logfile;命令切换日志

SQL> alter database drop logfile member '/u02/app/oradata/ZDJS/redo01.log';

Database altered.

SQL> alter database drop logfile member '/u02/app/oradata/ZDJS/redo02.log';

Database altered.

SQL> alter database drop logfile member '/u02/app/oradata/ZDJS/redo03.log';

Database altered.

SQL> select a.group#,a.status,b.member from v$log a,v$logfile b

    where a.group#=b.group# order by group#;

    GROUP# STATUS           MEMBER

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

          CURRENT          +DATA/zdjs/onlinelog/group_1.264.870617701

          CURRENT          +FLA/zdjs/onlinelog/group_1.256.870617713

          INACTIVE         +DATA/zdjs/onlinelog/group_2.265.870617759

          INACTIVE         +FLA/zdjs/onlinelog/group_2.257.870617769

          INACTIVE         +DATA/zdjs/onlinelog/group_3.266.870618057

          INACTIVE         +FLA/zdjs/onlinelog/group_3.258.870618067

 rows selected.

6.迁移临时表空间到ASM磁盘

SQL> select tablespace_name,file_name,bytes// size_m

    from dba_temp_files;

TABLESPACE_NAME      FILE_NAME                                    SIZE_M

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

TEMP                 /u02/app/oradata/ZDJS/temp01.dbf                 

SQL> alter tablespace temp add tempfile size 100m;

Tablespace altered.

SQL> select tablespace_name,file_name,bytes// size_m

    from dba_temp_files;

TABLESPACE_NAME      FILE_NAME                                    SIZE_M

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

TEMP                 +DATA/zdjs/tempfile/temp.267.870619111

TEMP                 /u02/app/oradata/ZDJS/temp01.dbf                 

SQL> alter database tempfile '/u02/app/oradata/ZDJS/temp01.dbf' drop ;

Database altered.

SQL> select tablespace_name,file_name,bytes// size_m

    from dba_temp_files;

TABLESPACE_NAME      FILE_NAME                                    SIZE_M

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

TEMP                 +DATA/zdjs/tempfile/temp.267.870619111

7.迁移控制文件、数据文件到ASM磁盘

在整个迁移过程中，只有这一步需要对数据库实例进行关闭、启动;这一步实际就是一个完全恢复的过程。

SQL> show parameter control 

NAME                                 TYPE        VALUE

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

control_file_record_keep_time        integer

control_files                        string      /u02/app/oradata/ZDJS/control0

                                                 .ctl, /u02/app/oradata/ZDJS/c

                                                 ontrol02.ctl, /u02/app/oradata

                                                 /ZDJS/control03.ctl

SQL> alter system set control_files='+DATA/ZDJS/CONTROLFILE/control01.ctl',

    '+DATA/ZDJS/CONTROLFILE/control02.ctl','+DATA/ZDJS/CONTROLFILE/control03.ctl'

    scope=spfile;

System altered.

SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup nomount

ORACLE instance started.

Total System Global Area   bytes

Fixed Size                   bytes

Variable Size              bytes

Database Buffers           bytes

Redo Buffers                 bytes

把数据库启动到nomount状态后使用rman进行恢复：

[oracle@std ~]$ rman target /

Recovery Manager: Release 10.2.0.4. - Production on Mon Feb  :: 

Copyright (c) , , Oracle.  All rights reserved.

connected to target database: ZDJS (not mounted)

RMAN> restore controlfile from '/u02/app/oradata/ZDJS/control01.ctl';

Starting restore at -FEB-

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid= devtype=DISK

channel ORA_DISK_1: copied control file copy

output filename=+DATA/zdjs/controlfile/control01.ctl

output filename=+DATA/zdjs/controlfile/control02.ctl

output filename=+DATA/zdjs/controlfile/control03.ctl

Finished restore at -FEB-

使用rman从最近的控制文件直接恢复控制文件，我们使用asmcmd工具确认一下恢复的控制文件是否存在：

ASMCMD> pwd

+DATA/ZDJS/CONTROLFILE

ASMCMD> ls

Backup.262.870616639

control02.ctl

control03.ctl

current.269.870620189

mount数据库后使用rman switch数据库：

SQL> alter database mount;

Database altered.

[oracle@std ~]$ rman target /
