裸设备
使用逻辑卷作为裸设备添加到tablespace中的方法----举例说明：
>0)lvcreate -L2g -n VolGroup00-datafileX VolGroup00
>1)AS root
>chown oracle:dba /dev/mapper/VolGroup00-datafileX
>raw /dev/raw/rawX /dev/mapper/VolGroup00-datafileX
>chown oracle:dba /dev/raw/rawX
>2) AS oracle
>ln -s /dev/raw/rawX /opt/ora9/oradata/big9/vgdatafileX
>3) AS oracle
>sqlplus "/as sysdba"
>alter tablespace users add
>datafile '/opt/ora9/oradata/big9/vgdatafileX' size 2040M reuse[@more@]
>0)lvcreate -L2g -n VolGroup00-datafileX VolGroup00
>1)AS root
>chown oracle:dba /dev/mapper/VolGroup00-datafileX
>raw /dev/raw/rawX /dev/mapper/VolGroup00-datafileX
>chown oracle:dba /dev/raw/rawX
>2) AS oracle
>ln -s /dev/raw/rawX /opt/ora9/oradata/big9/vgdatafileX
>3) AS oracle
>sqlplus "/as sysdba"
>alter tablespace users add
>datafile '/opt/ora9/oradata/big9/vgdatafileX' size 2040M reuse[@more@]
