In Linux, a raw device is used to create an oracle tablespace. Today, a test is performed to create a tablespace in linux: 1. create logical volume: run # lvcreate-L 100 M-n vg30 vg02. bind the logical volume to the bare device as the root user: under the root user, # raw/dev/raw/raw1/dev/vg01/oradta_life3. grant the read and write permissions of bare devices to oracle users: # chown today conducted a linux tablespace creation test: 1. create logical volume: run # lvcreate-L 100 M-n vg30 vg02. bind the logical volume to the bare device as the root user: under the root user, # raw/dev/raw/raw1/dev/vg01/oradta_life 3. grant the oracle user the read and write permissions for the bare device: # chown oracle: oinstall/dev/raw/raw14. create a connection to facilitate the application of the bare device: connect to the oracle user $ ln-s/dev/raw/raw1/home/oracle/oradata/raw_test 5. create a tablespace using a bare device: SQL> create tablespace raw_test datafile '/home/oracle/oradata/raw_test' size 50 m;
