#  Name:  cl_wlm_start
#
#  This script is used to start or refresh the WLM using the HA config dir.
#  All necessary checks to determine whether the WLM should be started or
#  refreshed should be done externally _before_ this script is called.
#
# Arguments:    NONE 
#
# Returns:      0 - Success
#               1 - Failure
#
# Called by:    node_up and reconfig_resource_acquire
#
# Environment:  VERBOSE_LOGGING
#

# Function:   main script body
# Purpose:    primary control mechanism for the script
# Parameters: none
# Returns:    0 = successful WLM start/refresh
#             1 = failed WLM start/refresh
