# DESCRIPTION:

# To delete a queue manager on the owning node. This script

# will also delete subdirectories on standby nodes, but leaves

# the mqs.ini file alone. Administrators will have to do the

# edit manually (for now).

#

# Arguments:

# $1: Queue Manager name

qmgr=$1

d=`/usr/mqm/hascript/hamqm_qm_directory $qmgr`

if [ -z "$d" ]

then

echo "Could not find information about queue manager \"$1\""

exit 1

fi

b=`basename $d`

if [ -r $d ]

then

# Ensure the queue manager has stopped

echo "ping qmgr" | runmqsc $qmgr

# Return code 0 is a normal end, so the qmgr is still running

if [ $? -eq 0 ]

then

echo "Queue Manager appears to still be running. Please stop it before"

echo "trying to delete it."

exit 1
