Linux rh4 通过raw设备建库
OS环境： RedHat EL4
DB 环境： Oracle 10.2.0
1、添加磁盘，建立逻辑卷
[root@RH4 ~]# fdisk -l
Disk /dev/sda: 85.8 GB, 85899345920 bytes

Disk /dev/sdb: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
[root@RH4 ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

3、建立数据文件的符号链接
[root@RH4 permissions.d]#
[root@RH4 permissions.d]# ln -s /dev/raw/raw1 /disk1/oradata/test/system01.dbf
[root@RH4 permissions.d]# ln -s /dev/raw/raw2 /disk1/oradata/test/sysaux01.dbf
[root@RH4 permissions.d]# ln -s /dev/raw/raw3 /disk1/oradata/test/rtbs01.dbf
[root@RH4 permissions.d]# ln -s /dev/raw/raw4 /disk1/oradata/test/users01.dbf
[root@RH4 permissions.d]# ln -s /dev/raw/raw5 /disk1/oradata/test/redo01a.log
[root@RH4 permissions.d]# ln -s /dev/raw/raw6 /disk1/oradata/test/redo02a.log
[root@RH4 permissions.d]# ln -s /dev/raw/raw7 /disk1/oradata/test/redo03a.log
[root@RH4 permissions.d]# ln -s /dev/raw/raw8 /disk1/oradata/test/control01.ctl
[root@RH4 permissions.d]# ln -s /dev/raw/raw9 /disk1/oradata/test/control02.ctl
[root@RH4 permissions.d]# ln -s /dev/raw/raw10 /disk1/oradata/test/temp01.dbf
[root@RH4 permissions.d]# ln -s /dev/raw/raw11 /u01/app/oracle/product/10.2.0/db_1/dbs/spfiletest.ora
[root@RH4 permissions.d]#
4、建立数据库文件的存放目录
[root@RH4 ~]# ls -ld /disk1/oradata/test
drwxr-xr-x 2 root root 4096 Apr 21 05:43 /disk1/oradata/test
[root@RH4 ~]# ls -ld /disk1/oradata/
drwxr-xr-x 6 oracle oinstall 4096 Apr 21 05:23 /disk1/oradata/
[root@RH4 ~]# chown -R oracle:oinstall /disk1/oradata/test
[root@RH4 ~]# ls -ld /disk1/oradata/test
drwxr-xr-x 2 oracle oinstall 4096 Apr 21 05:43 /disk1/oradata/test
[root@RH4 ~]#
5、在oracle home 下建立raw 配置文件
[oracle@RH4 ~]$ cat dbca.conf
spfile /u01/app/oracle/product/10.2.0/db_1/dbs/spfiletest.ora
system /disk1/oradata/test/system01.dbf
sysaux /disk1/oradata/test/sysaux01.dbf
undotbs1 /disk1/oradata/test/rtbs01.dbf
example /disk1/oradata/test/users01.dbf
redo1_1 /disk1/oradata/test/redo01a.log
redo1_2 /disk1/oradata/test/redo02a.log
redo1_3 /disk1/oradata/test/redo03a.log
control01 /disk1/oradata/test/control01.ctl
contorl02 /disk1/oradata/test/control02.ctl
temp /disk1/oradata/test/temp01.dbf
6、通过dbca 建库，选择raw 设备，然后选择raw的配置文件（dbca.conf)
------其中提示缺少：
‘redo1_1,redo1_2 ，redo文件必须以此命名',并需要undotbs1、users、example表空间，controlfile 文件命名contorl1、control2，spfile必须用绝对路径，不能用变量
----按照提示再增加raw 设备
[root@RH4 ~]# lvcreate -L 300m -n lv_example oravg
/dev/cdrom: open failed: Read-only file system
Logical volume "lv_example" created
[root@RH4 ~]#
[root@RH4 ~]# vi /etc/sysconfig/rawdevices
/dev/raw/raw12 /dev/mapper/oravg-lv_example
~
[root@RH4 ~]# ln -s /dev/raw/raw12 /disk1/oradata/test/example01.dbf
[root@RH4 ~]# vi /etc/sysconfig/rawdevices
/dev/raw/raw13 /dev/mapper/oravg-lv_control03
[root@RH4 ~]# ln -s /dev/raw/raw13 /disk1/oradata/test/control03.ctl
[oracle@RH4 ~]$ cat dbca.conf
spfile /u01/app/oracle/product/10.2.0/db_1/dbs/spfiletest.ora
system /disk1/oradata/test/system01.dbf
sysaux /disk1/oradata/test/sysaux01.dbf
undotbs1 /disk1/oradata/test/rtbs01.dbf
users /disk1/oradata/test/users01.dbf
redo1_1 /disk1/oradata/test/redo01a.log
redo1_2 /disk1/oradata/test/redo02a.log
redo1_3 /disk1/oradata/test/redo03a.log
control1 /disk1/oradata/test/control01.ctl
contorl2 /disk1/oradata/test/control02.ctl
contorl3 /disk1/oradata/test/control03.ctl
temp /disk1/oradata/test/temp01.dbf
example /disk1/oradata/test/example01.dbf
----------经过以上修改后，dbca 建库成功
