Strange ssh thing - Keys suddenly decide to stop working.
## Hi,
## I have a script that spawns a process on a remote virtuozzo(container based vm thing) machine then waits for it to complete. Its a bit hacked about but you should be able to get the idea.
function spawntpcc {
while ! ssh -v $vmhostnameprefix$1 <<EOF
"$tpccrootdir"/tpcc-mysql/tpcc_start -h localhost -d tpcc -u root -w "$3" -c 8 -r "$warmuptime" -l "$runtime" > /cm/shared/tpcc/"$runname"/"$3"/"$vmhostnameprefix""$1"...

Disappointing Performance Using 9i RAC with OCFS on Linux
...(130) 37.44 ( 25.28 / 12.16 ) 12.2 3.1 2156
raw-aio 10742 (349) 63.97 ( 47.44 / 16.53 ) 7.3 5.4 2191
ocfs-aio 10756 (352) 65.28 ( 47.84 / 17.44 ) 7.2 5 2092
Swap is used for ext2/ext3 (about 240Mb). No swapping for raw and ocfs.
All above runs with following parameters:
DB: Oracle 9iR2 (9.2.0.3)
TPCC Kit: 1000 Warehouse
Users: 100
Kernel : e.25 (RHAS2.1)
as you can see, ext3 and ext2 are 1/4th to 1/5th of raw/ocfs
this is on a big box, 1000 warehouses, thats like what, 500-600gb of
data.
the really really short answer is this :
Every benchmark we ever do has been on raw, because
