Hi ,
I am basically trying to crash the oracle database which has been
created using raw logical volumes . When I use 'dd' command to crash the
oracle database I find that the database is actually not crashing .
I used the following steps to create Oracle database on raw logical
volumes .
1. Created Physical Volumes's using pvcreate command
# pvcreate /dev/sdp
pvcreate -- physical volume "/dev/sdp" successfully created
# pvcreate /dev/sdq
pvcreate -- physical volume "/dev/sdq" successfully created
2. Created Volume Groups's
# vgcreate vg06 /dev/sdp
vgcreate -- INFO: using default physical extent size 4.00 MB
vgcreate -- INFO: maximum logical volume size is 255.99 Gigabyte
vgcreate -- doing automatic backup of volume group "vg06"
vgcreate -- volume group "vg06" successfully created and activated
# vgcreate vg07 /dev/sdq
vgcreate -- INFO: using default physical extent size 4.00 MB
vgcreate -- INFO: maximum logical volume size is 255.99 Gigabyte
vgcreate -- doing automatic backup of volume group "vg07"
vgcreate -- volume group "vg07" successfully created and activated
3. Created Logical Volume's
# lvcreate -l 25 -n control01.ctl /dev/vg06
lvcreate -- doing automatic backup of "vg06"
lvcreate -- logical volume "/dev/vg06/control01.ctl" successfully created
# lvcreate -l 25 -n control02.ctl /dev/vg06
lvcreate -- doing automatic backup of "vg06"
lvcreate -- logical volume "/dev/vg06/control02.ctl" successfully created
# lvcreate -l 100 -n system01.dbf /dev/vg06
lvcreate -- doing automatic backup of "vg06"
lvcreate -- logical volume "/dev/vg06/system01.dbf" successfully created
# lvcreate -l 100 -n log01.log /dev/vg07
lvcreate -- doing automatic backup of "vg07"
lvcreate -- logical volume "/dev/vg07/log01.log" successfully created
# lvcreate -l 100 -n log02.log /dev/vg07
lvcreate -- doing automatic backup of "vg07"
lvcreate -- logical volume "/dev/vg07/log02.log" successfully created
4. Removed the existing raw devices
[root@LNXSRVZ /dev]# rm /dev/raw/raw41
rm: remove `/dev/raw/raw41'? y
[root@LNXSRVZ /dev]# rm /dev/raw/raw42
rm: remove `/dev/raw/raw42'? y
[root@LNXSRVZ /dev]# rm /dev/raw/raw43
rm: remove `/dev/raw/raw43'? y
[root@LNXSRVZ /dev]# rm /dev/raw/raw44
rm: remove `/dev/raw/raw44'? y
[root@LNXSRVZ /dev]# rm /dev/raw/raw45
rm: remove `/dev/raw/raw45'? y
5.Recreate raw devices using 'mknod' command
# mknod /dev/vg06/rsystem01.dbf c 162 41
# mknod /dev/vg06/rcontrol01.ctl c 162 42
# mknod /dev/vg06/rcontrol02.ctl c 162 43
# mknod /dev/vg07/rlog01.log c 162 44
# mknod /dev/vg07/rlog02.log c 162 45
6. Used 'raw' command to bind raw device to block device
# raw /dev/vg06/rsystem01.dbf /dev/vg06/system01.dbf
/dev/raw/raw41: bound to major 58, minor 19
# raw /dev/vg06/rcontrol01.ctl /dev/vg06/control01.ctl
/dev/raw/raw42: bound to major 58, minor 17
# raw /dev/vg06/rcontrol02.ctl /dev/vg06/control02.ctl
/dev/raw/raw43: bound to major 58, minor 18
# raw /dev/vg07/rlog01.log /dev/vg07/log01.log
/dev/raw/raw44: bound to major 58, minor 20
# raw /dev/vg07/rlog02.log /dev/vg07/log02.log
/dev/raw/raw45: bound to major 58, minor 21
7. CHANGED THE FILE PERMISSIONS
# chmod 766 /dev/vg06
# chmod 766 /dev/vg06/*
# chmod 766 -R /dev/vg07
# chmod 766 -R /dev/vg07/*
# chown oracle:oinstall -R /dev/vg07

Please let me know if there is something fundamentally wrong in the
above steps used for creating Oracle database . After creating the database
I used the following 'dd' command to crash the database
dd if=/boot/vmlinux-2.4.2-2 of=/dev/sdp
Strangely this command does'nt seem to crash the database . Can
anybody help me out to crash the Oracle database ?

You need to be sure Oracle reads where your dd owerwrote its data. While Oracle doesn't read, it won't crash.
Even if it reads, it depends on what have been recovered. You might just have errors in alert.log file telling you you have corrupted blocks, but the databse may not crash.
The more efficient would be to make sure dd writes over the system tablespace.
