将文件系统数据库迁移到ASM中
使用裸设备配置ASM实例
http://www.cnblogs.com/myrunning/p/4270849.html
1.查看我们创建的磁盘组
[oracle@std ~]$ export ORACLE_SID=+ASM
[oracle@std ~]$ sqlplus '/as sysdba' SQL*Plus: Release 10.2.0.4. - Production on Mon Feb :: Copyright (c) , , Oracle. All Rights Reserved. Connected to:
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$asm_diskgroup; NAME TOTAL_MB FREE_MB
------------------------------ ---------- ----------
DATA
FLA
2.启动数据库实例查看数据文件等
SQL> select * from v$dbfile;
FILE# NAME
---------- --------------------------------------------------
/u02/app/oradata/ZDJS/users01.dbf
/u02/app/oradata/ZDJS/sysaux01.dbf
/u02/app/oradata/ZDJS/undotbs01.dbf
/u02/app/oradata/ZDJS/system01.dbf
/u02/app/oradata/ZDJS/example01.dbf
/u02/app/oradata/ZDJS/rlsc01.dbf
rows selected.
SQL> select file#,name from v$tempfile;
FILE# NAME
---------- --------------------------------------------------
/u02/app/oradata/ZDJS/temp01.dbf
SQL> show parameter control_
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer
control_files string /u02/app/oradata/ZDJS/control0
.ctl, /u02/app/oradata/ZDJS/c
ontrol02.ctl, /u02/app/oradata
/ZDJS/control03.ctl
SQL> show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /u02/app/product/10.2./db_1/d
bs/spfileZDJS.ora
SQL> select group#,member from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------
/u02/app/oradata/ZDJS/redo03.log
/u02/app/oradata/ZDJS/redo02.log
/u02/app/oradata/ZDJS/redo01.log
3.对RDBMS做一个备份
[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 (DBID=) RMAN> backup as copy database format '+DATA'; Starting backup at -FEB-

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
control01.ctl
control02.ctl
control03.ctl
current.268.870620187
current.269.870620189
current.270.870620189
mount数据库后使用rman switch数据库：
SQL> alter database mount; Database altered.
[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 (DBID=, not open) RMAN> list copy; using target database control file instead of recovery catalog List of Datafile Copies
