N3090 Training

This week I have a Belgian company called IMAS for the main part of N3090. The last day’s we’re going to do same custom labs for eDirectory.

They have a nice enviroment with Vmware ESX and a couple of OES 2 servers. The funny part is that they experience the same problems with OES2 and Vmware than I do. Bad performance with NSS and a high utilization of NDSD. I will give the same tips and tricks during this week, but maybe its wise to read my other post on NSS performance with ESX.

Hope the like the training we put together for them.

Update 27-1-2009: A question from one of the student was how we can see witch users has a file open. So I googled around and found this script:

#/bin/bash
# description: List open files on OES
# author:      Olaf Zerfowski
# version:     0.01
# date:        04-20-2006

maxcon=`ncpcon connection 2>/dev/nul| sed -ne  "s/.*Connection Slots Allocatedt//pg"`

count=0

if [ "$1" == "" ]
then
searchstring=/media/nss/
else
searchstring=$1
fi

echo "Max Connections=$maxcon"
echo "SearchString=$searchstring"

while  [ $count -lt $maxcon ]
do
conninfo=`ncpcon connections $count 2>nul| egrep "Name|$searchstring"`
if echo $conninfo | grep "$searchstring" 1>/dev/nul 2>&1
then
       echo Connection $count
       ncpcon connections $count 2>nul| egrep "Name|$searchstring"
fi
count=`expr $count + 1`

done
