通过辅助库（Auxiliary）做ASM迁移案例
系统环境：
操作系统：RedHat EL55
Oracle ： Oracle 10gR2
通过辅助库建立ASM迁移，可以很方便将文件系统的存储异机迁移；并且可减少数据库的停机时间，本案例为测试案例，，目标库和辅助库都在同一台机器上。
1、建立ASM实例
[oracle@rh55 ~]$export ORACLE_SID=+ASM
[oracle@rh55 ~]$sqlplus '/as sysdba'
SQL*Plus: Release 10.2.0.1.0 - Production on Thu May 29 11:39:49 2014
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to an idle instance.
11:39:50 SYS@ +ASM>startup nomount
ASM instance started
Total System Global Area 83886080 bytes
Fixed Size 1217836 bytes
Variable Size 57502420 bytes
ASM Cache 25165824 bytes
11:39:57 SYS@ +ASM>select name ,state from v$asm_diskgroup;
NAME STATE
------------------------------ -----------
DG1 DISMOUNTED
RCY1 DISMOUNTED
Elapsed: 00:00:00.24
11:40:14 SYS@ +ASM>alter diskgroup dg1 mount;
Diskgroup altered.
Elapsed: 00:00:04.88
11:40:29 SYS@ +ASM>alter diskgroup rcy1 mount;
Diskgroup altered.
Elapsed: 00:00:04.77
2、建立并配置辅助库
Target DB：test1
Auxiliary DB: test1asm
11:41:58 SYS@ test1>show parameter name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string test1
db_unique_name string test1
global_names boolean FALSE
instance_name string test1
service_names string test1
11:42:06 SYS@ test1>show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /u01/app/oracle/product/10.2.0
/db_1/dbs/spfiletest1.ora
11:42:11 SYS@ test1>create pfile from spfile;
File created.
建立辅助库初始化参数文件：
[oracle@rh55 dbs]$cp inittest1.ora inittest1asm.ora
[oracle@rh55 dbs]$ cat inittest1asm.ora
*.background_dump_dest='$ORACLE_BASE/admin/test1asm/bdump'
*.control_files='+dg1/test1asm/controlfile/control01.ctl'
*.core_dump_dest='$ORACLE_BASE/admin/test1asm/cdump'
*.db_block_size=8192
*.db_cache_size=30M#DEMO
*.db_file_multiblock_read_count=16
*.db_name='test1asm'
*.instance_name='test1asm'
*.log_archive_dest_1='location=+rcy1'
*.log_archive_format='arch_%t_%s_%r.log'
*.optimizer_mode='choose'
*.parallel_threads_per_cpu=4#SMALL
*.pga_aggregate_target=30M#DEMO
*.query_rewrite_enabled='true'
*.query_rewrite_integrity='trusted'
*.sga_target=240M
*.shared_pool_size=20M#DEMO
*.star_transformation_enabled='true'
*.undo_management='auto'
*.undo_tablespace='undotbs1'
*.user_dump_dest='$ORACLE_BASE/admin/test1asm/udump'
*.db_create_file_dest='+DG1'
*.db_file_name_convert=("/u01/app/oracle/oradata/test1","+dg1/test1asm/datafile","/u01/app/oracle/oradata/test1","+dg1/test1asm/tempfile")
*.log_file_name_convert=("/u01/app/oracle/oradata/test1","+dg1/test1asm/onlinelog")
db_recovery_file_dest='+rcy1'
db_recovery_file_dest_size=2g
*.audit_file_dest='$ORACLE_BASE/admin/test1asm/adump'/bdump
建立辅助库相关目录：
[oracle@rh55 dbs]$ mkdir -p $ORACLE_BASE/admin/test1asm/cdump
[oracle@rh55 dbs]$ mkdir -p $ORACLE_BASE/admin/test1asm/udump
[oracle@rh55 dbs]$ mkdir -p $ORACLE_BASE/admin/test1asm/adump
建立口令文件：
[oracle@rh55 dbs]$ orapwd file=orapwtest1asm password=oracle entries=3
建立tnsnames文件：
[oracle@rh55 admin]$ cat tnsnames.ora
TEST1ASM =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rh55)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = test1asm)
( UR = A )
)
)
TEST1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rh55)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = test1)
)
)
3、迁移文件系统到ASM存储
对目标库备份：
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP on;
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/disk2/bak/test1/auto_ctl_%d_%F';
RMAN> run{
2> shutdown immediate;
3> startup force mount;
4> allocate channel ch1 device type disk;
5> backup as compressed backupset database format '/disk2/bak/test1/%d_%s.bak'
6> plus archivelog format '/disk2/bak/test1/arch_%U.bak'
7> tag='full_log';
8> release channel ch1;}
启动辅助库实例：
[oracle@rh55 dbs]$export ORACLE_SID=test1asm
[oracle@rh55 dbs]$ sqlplus '/as sysdba'
