running lmgrd

hi,
we have a setup of three sun ultra 10 computers. /cadence is mounted
on all the three. every day in morning when we start we have to run
lmgrd on all the three systems to start cadence. can anyone tell me a
way so that we donot have to run lmgrd on each system every time we
switch-on?


thanks in advance.

Normally a startup script is placed in /etc/rc/rc3.d so start lmgrd at
boot time. This should be described in the Cadence administrators
documentation.

I am doing this from home and making this all up so expect an error or
three in the script
----------------
# /etc/rc/rc3.d/S99cadenceLicenses
# needs not checked, assumed available in init 3 mode
# needs /cadence automount complete
# needs user $CADENCELM to exist

# making LMBINPATH and the licese file local allows it to work
# even if network mounts fail. Also cadence would be a local user
# to avoid dependance on NIS

# who to run as
CADENCELM=cadence
# path to lincese binaries
LMBINPATH=/cadence/tools.sun4v/bin
# license file to server
LMLICFILE=/cadence/licenses/licenseA.dat
# log file
LMLOGFILE=/var/logs/cadenceLM.log

# path to other binaries might be needed if the license
# file does not specify the full path

PATH=${LMBINPATH}:$PATH
export PATH

# run lmgrd as user cadence, makes logfile owned by cadence
echo "Starting Cadence License Manager\n"
su $CADENCELM -c "$LMBINPATH/lmstart -c $LMLICFILE 2>>&1 $LMLOGFILE"
---------------

Lmgrd needs to run only on the actual license server that hosts the
liceneses. Do you have 3 sets of licenses (3 license files), each
license set bound to a separate host? That is a strange setup. Normally
1 machine would be designated as the licenses host and it would serve
out licenses to many individual machines. When you get more than 3
users, closer to 10 or more you can get away with fewer licenses than
end users as not everyone will be working at the same time.

Also I would look into using a new PC running linux and compare
simulation times VS the sun ultra 10's. Get a new $100 disc drive put it
in a spare PC install Linux and Cadence then point it to one of your
existing license servers. This should allow you to compare operation times.

Shutting down and restarting a Sun everyday is a little unusual. Why not
just leave them running?

thanks a lot, this script is working...........

license file is something like ..
#
#
SERVER name1 80b0.. 5280
SERVER name2 80b1.. 5280
SERVER name3 80b2.. 5280

/cadence partition is mounted on all the three systems. lmgrd is to be
run on all three to start cadence. can you suggest why is this so?

after implementing the script given by you lmgrd starts at boot time.

once again thanks for your prompt help.

Because you have elected to have fault tolerant licensing. Fault tolerant
licensing has three license servers, whereas normal licensing just has a single
license server.
