使用raw device建oracle 数据库
使用raw device建oracle 数据库，与使用文件系统建库的不同是，在使用dbca建库前先作如下动作： 1 分区Device Boot Start End Blocks> /dev/sde1 1 63 506016 83 Linux
/dev/sde2 64 126 506047+ 83 Linux
/dev/sde3 127 189 506047+ 83 Linux
/dev/sde4 190 1305 8964270 5 Extended
/dev/sde5 190 688 4008186 83 Linux
/dev/sde6 689 813 1004031 83 Linux
/dev/sde7 814 838 200781 83 Linux
/dev/sde8 839 854 128488+ 83 Linux
/dev/sde9 855 870 128488+ 83 Linux
/dev/sde10 871 886 128488+ 83 Linux
/dev/sde11 887 899 104391 83 Linux
/dev/sde12 900 912 104391 83 Linux
/dev/sde13 913 914 16033+ 83 Linux
/dev/sde14 915 916 16033+ 83 Linux
/dev/sde15 917 1305 3124611 83 Linux
2 写raw : vi /etc/sysconfig/rawdevices
/dev/raw/raw1 /dev/sde1
/dev/raw/raw2 /dev/sde2
/dev/raw/raw3 /dev/sde3
/dev/raw/raw4 /dev/sde5
/dev/raw/raw5 /dev/sde6
/dev/raw/raw6 /dev/sde7
/dev/raw/raw7 /dev/sde8
/dev/raw/raw8 /dev/sde9
/dev/raw/raw9 /dev/sde10
/dev/raw/raw10 /dev/sde11
/dev/raw/raw11 /dev/sde12
/dev/raw/raw12 /dev/sde13
/dev/raw/raw13 /dev/sde14
/dev/raw/raw14 /dev/sde15
# service rawdevices restart
3 连接文件
ln -s /dev/raw/raw1 /oracle/oradata/orcl/orcl_system_raw_512m
ln -s /dev/raw/raw2 /oracle/oradata/orcl/orcl_sysaux_raw_512m
ln -s /dev/raw/raw3 /oracle/oradata/orcl/orcl_undotbs_raw_512m
ln -s /dev/raw/raw4 /oracle/oradata/orcl/orcl_data1_raw_4096m
ln -s /dev/raw/raw5 /oracle/oradata/orcl/orcl_temp_raw_1024m
ln -s /dev/raw/raw6 /oracle/oradata/orcl/orcl_user_raw_200m
ln -s /dev/raw/raw7 /oracle/oradata/orcl/orcl_redo1_raw_120m
ln -s /dev/raw/raw8 /oracle/oradata/orcl/orcl_redo2_raw_120m
ln -s /dev/raw/raw9 /oracle/oradata/orcl/orcl_redo3_raw_120m
ln -s /dev/raw/raw10 /oracle/oradata/orcl/orcl_control1_raw_100m
ln -s /dev/raw/raw11 /oracle/oradata/orcl/orcl_control2_raw_100m
ln -s /dev/raw/raw12 /oracle/oradata/orcl/orcl_spfile_raw_5m
ln -s /dev/raw/raw13 /oracle/oradata/orcl/orcl_pwdfile_raw_5m
ln -s /dev/raw/raw14 /oracle/oradata/orcl/orcl_data2_raw_3000m
4 写RAW方式安装配置文件 vi orcl_raw.conf
system = /oracle/oradata/orcl/orcl_system_raw_512m
sysaux = /oracle/oradata/orcl/orcl_sysaux_raw_512m
undotbs1= /oracle/oradata/orcl/orcl_undotbs_raw_512m
data = /oracle/oradata/orcl/orcl_data1_raw_4096m
temp = /oracle/oradata/orcl/orcl_temp_raw_1024m
users = /oracle/oradata/orcl/orcl_user_raw_200m
redo1_1 = /oracle/oradata/orcl/orcl_redo1_raw_120m
redo1_2 = /oracle/oradata/orcl/orcl_redo2_raw_120m
redo1_3 = /oracle/oradata/orcl/orcl_redo3_raw_120m
control1= /oracle/oradata/orcl/orcl_control1_raw_100m
control2= /oracle/oradata/orcl/orcl_control2_raw_100m
spfile = /oracle/oradata/orcl/orcl_spfile_raw_5m
pwdfile = /oracle/oradata/orcl/orcl_pwdfile_raw_5m
5 dbca建库
上面要注意的是，需要配置orcl_raw.conf文件，选文件系统时，选orcl_raw.conf就行了，这样dbca才能使用对应raw device.
