Script to completely shutdown the concurrent manager

Question

Use this script to shutdown the concurrent manager completely. It will wait till all processes die.
#!/bin/sh
# Author: Praveen Gattu
# Created: June 2007
# Figure out how you want to pass the variables DB_USER (username
# for APPS schema) and DB_PSWD (password for APPS). You can
# hardcode in this script (not recommended), prompt the user
# to enter them, etc.
# stop the concurrent manager
$SCRIPTS_TOP/adcmctl.sh stop $DB_USER/$DB_PSWD
# check if the processes are alive
SPOOL_FILE="$APPLTMP/stop_cm_$TWO_TASK.tmp"
while [ "$RETURN_VALUE" != "0" ]; do
sqlplus -silent $DB_USER/$DB_PSWD << EOF
spool $SPOOL_FILE
select concurrent_queue_name, running_processes
from fnd_concurrent_queues
where running_processes > 0;
spool off
EOF
egrep --silent "no rows selected" $SPOOL_FILE
RETURN_VALUE=$?
if [ $RETURN_VALUE -ne 0 ]; then
echo "Concurrent manager processes are still active. Sleeping for 10 seconds..."
sleep 10
fi
done
rm $SPOOL_FILE
echo "** Concurrent Manager and its processes are stopped **"

Far as I know DSH exist by default in AIX env, but you can create it on Linux\Unix env.
Creating DSH in a Linux Env.
1 - Configure passwordless SSH between Nodes using root user.
2 - Create a file /etc/dsh.conf with all hostsname separated with space in a line ( ex. node1 node2 node3)
3-  Create a script "/usr/local/scripts/dsh" as follow:
#!/bin/bash
COMANDO=$*
NODES=`cat /etc/dsh.conf`
     for NODE in $NODES
     do
     echo $NODE:
ssh $NODE $COMANDO
     done
exit 0
4 - Change permission of file /usr/local/scripts/dsh to 775
Just run
# /usr/local/scripts/dsh date
or
# /usr/local/scripts/dsh /u01/app/grid/bin/crsctl stop crs
