Solaris oracle数据库离线迁移

一、测试环境描述
1.操作系统版本:solaris 10;
2.原测试数据库oracle 10g安装在系统分区/u01目录下,并且数据库也创建在子目录下,大概2.8G;
3.磁盘分区/dev/dsk/c1t4d0s0有60多G的空间。

root@sun10 # du -sh /u01
2.8G /u01
root@sun10 # ls /u01/oracle
arclog oraInventory product
root@sun10 # ls /u01/oracle/product/db_1/
OPatch flash_recovery_area lib32 ord sqlplus
admin has log oui srvm
assistants hs md owm sun10_ora10g
bin install mesg perl sysman
cdata install.platform mgw plsql tg4ifmx
cfgtoollogs instantclient32 network precomp tg4ingr
clone inventory nls racg tg4sybs
config javavm oc4j rdbms tg4tera
crs jdbc odbc relnotes uix
css jdk olap root.sh wwg
ctx jlib opmn root.sh.old xdk
dbs jre oraInst.loc slax
demo ldap oracore sqlj
diagnostics lib oradata sqlnet.log
二、测试目标:
把系统盘/u01目录下oracle数据拷贝到另一块磁盘的分区/dev/dsk/c1t4d0s0下,确保oracle数据及属性等完整拷贝到新的磁盘空间,并且数据库能正常运行。

三、实施过程:
1.检测环境:
数据库运行正常:
SQL> select instance_name,status from v$instance;

INSTANCE_NAME STATUS
---------------- ------------
ora10g OPEN

空间使用情况:
SQL> select df.tablespace_name "表空间名",totalspace "总空间M",freespace "剩余空间M",round((1-freespace/totalspace)*100,2) "使用率%"
2 from
3 (select tablespace_name,round(sum(bytes)/1024/1024) totalspace
4 from dba_data_files
5 group by tablespace_name) df,
6 (select tablespace_name,round(sum(bytes)/1024/1024) freespace
7 from dba_free_space
8 group by tablespace_name) fs
9 where df.tablespace_name=fs.tablespace_name;

表空间情况:

表空间名 总空间M 剩余空间M 使用率%
------------------------------ ---------- ---------- ----------
SYSTEM 480 9 98.13
USERS 5 5 0
ZMQ_DATA 50 50 0
SYSAUX 240 2 99.17
UNDOTBS1 25 1 96

zmq用户表:
SQL> select * from zmq.test_emp;

2.关闭oracle监听和实例
-bash-3.00$ lsnrctl stop

LSNRCTL for Solaris: Version 10.2.0.1.0 - Production on 14-JUN-2012 14:50:24

Copyright (c) 1991, 2005, Oracle. All rights reserved.

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=sun10)(PORT=1521)))
The command completed successfully

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

3.检查原目录大小和文件数量
-bash-3.00$ pwd
/u01
-bash-3.00$ du -sk oracle/
2948626 oracle
-bash-3.00$ ls -alR |wc -l
28016
4.挂载新目录挂载磁盘c1t4d0s0
root@sun10 # mkdir u01new
root@sun10 # mount /dev/dsk/c1t4d0s0 /u01new
root@sun10 # df -h

/dev/dsk/c1t4d0s0 67G 64M 66G 1% /u01new #确认有足够的空间

5.利用cpio命令拷贝
root@sun10 # cd /u01
root@sun10 # pwd
/u01
root@sun10 # ls
oracle
root@sun10 # time find . |cpio -pdmu /u01new/

real 2m35.127s #花了2分多钟
user 0m2.100s

root@sun10 # du -sk oracle/
3020200 oracle #目录大小跟源拷贝目录有差异,大一点
root@sun10 # ls -alR |wc -l
28016 #说明拷贝的文件数量跟源目录一致

6.
重新挂载

root@sun10 # mv u01 u01bak
root@sun10 # mkdir u01
root@sun10 # umount /u01new
root@sun10 # mount /dev/dsk/c1t4d0s0 /u01
root@sun10 # ls /u01

root@sun10 #
root@sun10 # du -sk /u01
3020201 /u01

注:
如果原/u01是mount了磁盘,这时只需要
umount /u01 #卸载原来磁盘分区
umount /u01new #卸载/dev/dsk/c1t4d0s0
mount /dev/dsk/c1t4d0s0 /u01 #将/dev/dsk/c1t4d0s0挂载到/u01

6.启动数据库,验证数据
root@sun10 # su - oracle
启用监听
-bash-3.00$ lsnrctl start
