Here is what I did to accomplish an Orion test on a new
server I am currently installing oracle on and configuring. The orion
executable (11R2 is the first release to included this package) is stored under
$ORACLE_HOME/bin directory.
user1a@serv01[dpprod]:/u01/app/oracle/product/11.2.0/db_1/bin>
ll *orion*
-rwxr-xr-x 1
oracle dba 8698817 Sep 4 2010 orionO*
-rwxr-x--x 1
oracle dba 8700950 Jun 29 21:34 orion*
(Note that this is on Linux 64 bit).
I created a directory under /u01/app/oracle/ called
orion.
I then created the following file in that same orion
directory: asm.vols.lun
I used the information from /dev/oracleasm/disks to populate
it:
user1a@sevr2:/u01/app/oracle/orion>
ls -l /dev/oracleasm/disks/
total 0
brw-rw---- 1

oracle dba 8, 113 Sep 29 10:12 VOL6
Here is the content of the asm.vols.lun file:
user1a@sevr2:/u01/app/oracle/orion>
cat asm.vols.lun
/dev/oracleasm/disks/VOL1
/dev/oracleasm/disks/VOL2
/dev/oracleasm/disks/VOL3
/dev/oracleasm/disks/VOL4
/dev/oracleasm/disks/VOL5
/dev/oracleasm/disks/VOL6
Note that this server is using RDAC (Redundant Disk Array
Controller). I was able to determine this by noting that there were no
files in the /dev/mapper/ directory (the storage is direct attached):
user1a@sevr2:/u01/app/oracle/orion>
ll /dev/mapper
total 0
crw-------
1 root root 10, 63 Sep 29 10:12 control
drwxr-xr-x
2 root root 60 Sep 29 10:12 ./
drwxr-xr-x 12
root root 4380 Oct 4 11:38 ../
If this was multipath as it is on the sevr1 (esan) the
mapper directory would be populated:
user1a@sevr1[dbprod]:/u01/app/oracle/product/11.2.0/db_1/bin>
ll /dev/mapper

If that where the case then my asm.vols.lun file contents
would have looked like this:
/dev/mapper/mpath1p1
/dev/mapper/mpath13p1
/dev/mapper/mpath14p1
/dev/mapper/mpath15p1
/dev/mapper/mpath16p1
/dev/mapper/mpath17p1
/dev/mapper/mpath2p1
/dev/mapper/mpath3p1
/dev/mapper/mpath4p1
/dev/mapper/mpath5p1
/dev/mapper/mpath9p1
/dev/mapper/mpath10p1
/dev/mapper/mpath11p1
/dev/mapper/mpath12p1
Here is the
command line entries I used to execute the orion test:
./$ORACLE_HOME/bin/orion
-run advanced -testname asm.vols -type seq -matrix point -num_large 6
-num_small 0 -duration 120 -write 0
Note:
(-num_large typically is assigned the same number as the number of lun’s you
have.)
Here is the output from the command execution:
ORION: ORacle IO

6 FILEs found.
Maximum Large MBPS=1574.57
@ Small=0 and Large=6
As you can see, I am getting 1.5 gbs/sec.
The rule of thumb to expect for
these i/o subsystems is around 250 MB/s per LUN. Therefore for six
LUNs it would be 1.5 GB/s.
And I am happy, as that is what I
got.
Thx
