丸趣 TV 小编给大家分享一下 oracle 中数据 fs 到 asm 迁移的示例分析，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
（RedHat 10g Oracle 环境）
1、配置 Oracle Cluster Synchronization（CSS）
要想使用 ASM，必须先配置并启动 CSS
[root@redhat10g ~]# cd /u01/app/oracle/product/10.2.0/db_1/bin
[root@redhat10g bin]# ./localconfig add
2、配置 Automatic Storage Management（ASM）实例参数
[oracle@aix201 ~]$vi /u01/app/oracle/product/10.2.0/db_1/dbs/init+ASM.ora
instance_type= asm
asm_diskstring= /dev/mapper/asmvg-*
asm_diskgroups= DG1 , RCY1
large_pool_size=12m
background_dump_dest=/u01/app/oracle/product/10.2.0/db_1/admin/+ASM/bdump
core_dump_dest=/u01/app/oracle/product/10.2.0/db_1/admin/+ASM/cdump
user_dump_dest=/u01/app/oracle/product/10.2.0/db_1/admin/+ASM/udump
3、启动 asm 实例
[oracle@redhat10g ~]$ export ORACLE_SID=+ASM
[oracle@redhat10g ~]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.1.0 – Production on Sun Jun 29 17:04:44 2014
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.
SQL startup
ASM instance started
Total System Global Area 83886080 bytes
Fixed Size 1217836 bytes
Variable Size 57502420 bytes
ASM Cache 25165824 bytes
4、创建裸设备，修改用户和权限
1）添加磁盘；
2）为磁盘分区：
[root@redhat10g ~]# fdisk /dev/sdb
Device Boot Start End Blocks Id System
/dev/sdb1 1 2610 20964793+ 83 Linux
3）创建物理卷（pv）：
[root@redhat10g ~]# pvcreate /dev/sdb1
/dev/cdrom: open failed: Read-only file system
Attempt to close device /dev/cdrom which is not open.
Physical volume /dev/sdb1 successfully created
查看 pv 的信息：
4）创建卷组：
[root@redhat10g ~]# vgcreate asmvg /dev/sdb1
5）创建逻辑卷 lv：
[root@redhat10g ~]# lvcreate -n datalv1 -L 5gb asmvg
/dev/cdrom: open failed: Read-only file system
Logical volume datalv1 created
[root@redhat10g ~]# lvcreate -n datalv2 -L 5gb asmvg
/dev/cdrom: open failed: Read-only file system
Logical volume datalv2 created
[root@redhat10g ~]# lvcreate -n ocrdisklv1 -L 4.5gb asmvg
/dev/cdrom: open failed: Read-only file system
Logical volume ocrdisklv1 created
[root@redhat10g ~]# lvcreate -n ocrdisklv2 -L 4.5gb asmvg
/dev/cdrom: open failed: Read-only file system
Logical volume ocrdisklv2 created
6）绑定裸设备：
[root@redhat10g ~]# raw /dev/raw/raw1 /dev/mapper/asmvg-datalv1
/dev/raw/raw1: bound to major 253, minor 2
[root@redhat10g ~]# raw /dev/raw/raw2 /dev/mapper/asmvg-datalv2
/dev/raw/raw2: bound to major 253, minor 3
[root@redhat10g ~]# raw /dev/raw/raw3 /dev/mapper/asmvg-
asmvg-datalv1 asmvg-datalv2 asmvg-ocrdisklv1 asmvg-ocrdisklv2
[root@redhat10g ~]# raw /dev/raw/raw3 /dev/mapper/asmvg-ocrdisklv1
/dev/raw/raw3: bound to major 253, minor 4
[root@redhat10g ~]# raw /dev/raw/raw4 /dev/mapper/asmvg-ocrdisklv2
/dev/raw/raw4: bound to major 253, minor 5
服务器启动自动挂载裸设备：
[root@redhat10g ~]# vi /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/mapper/asmvg-datalv1
/dev/raw/raw2 /dev/mapper/asmvg-datalv2
/dev/raw/raw3 /dev/mapper/asmvg-ocrdisk1
/dev/raw/raw4 /dev/mapper/asmvg-ocrdisk2
重启服务验证能否挂载：
[root@redhat10g ~]# service rawdevices restart
Assigning devices:
/dev/raw/raw1 — /dev/mapper/asmvg-datalv1
/dev/raw/raw1: bound to major 253, minor 2
/dev/raw/raw2 — /dev/mapper/asmvg-datalv2
/dev/raw/raw2: bound to major 253, minor 3
/dev/raw/raw3 — /dev/mapper/asmvg-ocrdisklv1
/dev/raw/raw3: bound to major 253, minor 4
/dev/raw/raw4 — /dev/mapper/asmvg-ocrdisklv2
/dev/raw/raw4: bound to major 253, minor 5
7）修改设备属性：
[root@redhat10g raw]# chown -R oracle:oinstall /dev/raw/raw1
[root@redhat10g raw]# chown -R oracle:oinstall /dev/raw/raw2
[root@redhat10g raw]# chown -R oracle:oinstall /dev/raw/raw3
[root@redhat10g raw]# chown -R oracle:oinstall /dev/raw/raw4
[root@redhat10g ~]# chown -R oracle:oinstall /dev/mapper/asmvg-datalv1
[root@redhat10g ~]# chown -R oracle:oinstall /dev/mapper/asmvg-datalv2
[root@redhat10g ~]# chown -R oracle:oinstall /dev/mapper/asmvg-ocrdisklv1
[root@redhat10g ~]# chown -R oracle:oinstall /dev/mapper/asmvg-ocrdisklv2
5、创建 ASM 磁盘组
为了能使 ASM 启动时，自动挂载磁盘和磁盘组，将下边的参数添加到初始化文件中：
asm_diskstring= /dev/mapper/asmvg-*
asm_diskgroups= DG1 , RCY1
6、修改参数：
SQL alter system set db_create_file_dest= +dg1 scope=spfile;
System altered.
SQL alter system set control_files= +dg1 scope=spfile;
System altered.
7、转储控制文件
RMAN shutdown immediate;
using target database control file instead of recovery catalog
database closed
database dismounted
Oracle instance shut down
RMAN startup nomount;
connected to target database (not started)
Oracle instance started
Total System Global Area 1258291200 bytes
Fixed Size 1219160 bytes
Variable Size 318768552 bytes
Database Buffers 922746880 bytes
Redo Buffers 15556608 bytes

channel ORA_DISK_1: copied control file copy
output filename=+DG1/prod/controlfile/backup.256.851554395
Finished restore at 29-JUN-14
8、转储数据文件
RMAN alter database mount;
database mounted

using channel ORA_DISK_1
starting media recovery

Finished recover at 29-JUN-14
RMAN alter database open;
database opened
10、迁移临时表空间
SQL select name from v$datafile;
NAME
——————————————————————————–
+DG1/prod/datafile/system.257.851554507
+DG1/prod/datafile/undotbs1.260.851554683
+DG1/prod/datafile/sysaux.258.851554603
+DG1/prod/datafile/users.261.851554691
+DG1/prod/datafile/example.259.851554659
SQL select name from v$tempfile;
NAME
——————————————————————————–
/u01/app/oracle/oradata/prod/temp01.dbf
/u01/app/oracle/product/10.2.0/db_1/dbs/temp01.dbf
报错：
SQL alter tablespace temp drop tempfile /u01/app/oracle/product/10.2.0/db_1/dbs/temp01.dbf
alter tablespace temp drop tempfile /u01/app/oracle/product/10.2.0/db_1/dbs/temp01.dbf
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [drop tempfile-2], [3], [7], [], [],
[], [], []
11、迁移联机日志组：
SQL alter database add logfile (+dg1 , +rcy1) size 10m;
Database altered.
SQL alter database add logfile (+dg1 , +rcy1) size 10m;
Database altered.
SQL alter database add logfile (+dg1 , +rcy1) size 10m;
Database altered.
SQL select group#,member from v$logfile order by 1;
GROUP# MEMBER
———- ————————————————————
1 /u01/app/oracle/oradata/prod/redo01.log
2 /u01/app/oracle/oradata/prod/redo02.log
3 /u01/app/oracle/oradata/prod/redo03.log
4 +DG1/prod/onlinelog/group_4.265.851556583
4 +RCY1/prod/onlinelog/group_4.256.851556585
5 +DG1/prod/onlinelog/group_5.266.851556591
5 +RCY1/prod/onlinelog/group_5.257.851556595
6 +DG1/prod/onlinelog/group_6.267.851556599
6 +RCY1/prod/onlinelog/group_6.258.851556601
SQL alter database drop logfile group 1;
Database altered.
SQL alter database drop logfile group 2;
alter database drop logfile group 2
*
ERROR at line 1:
ORA-01623: log 2 is current log for instance prod (thread 1) – cannot drop
ORA-00312: online log 2 thread 1: /u01/app/oracle/oradata/prod/redo02.log
SQL alter database drop logfile group 3;
Database altered.
由于第二组日志还没有归档所以现在无法删除，所以要切换日志，使日志组 2 变成非活动状态
SQL alter system switch logfile;
SQL select group#,members,status from v$log;
GROUP# MEMBERS STATUS
———- ———- —————-
2 1 INACTIVE
4 2 CURRENT
5 2 INACTIVE
6 2 INACTIVE
SQL alter database drop logfile group 2;
Database altered.
12、调整 recover area 参数
SQL show parameter recover
NAME TYPE VALUE
———————————— ———– ——————————
db_recovery_file_dest string /u01/app/oracle/flash_recovery
_area
db_recovery_file_dest_size big integer 2G
recovery_parallelism integer 0
SQL alter system set db_recovery_file_dest= +rcy1 scope=spfile;
System altered.
SQL alter system set db_recovery_file_dest_size=2g scope=spfile;
System altered
