# File Name:
#      applyPerfTuningTemplate.py
# Purpose:
#      Apply pre-defined performance tuning templates to a specific
#      application server instance or all instances in a cluster. Three
#      templates are pre-defined (default, peak, and development);
#      however, these files can easily be modified to create your own custom
#      tuning template.
# Usage:
#      wsadmin -f applyPerfTuningTemplate.py [-nodeName <node> -serverName <server>] [-clusterName <cluster>] -templateFile <file>
#
#         -nodeName, -serverName"
#            Used together to target a specific server instance for tuning. Cannot be
#            used in conjunction with the -clusterName option.
#         -clusterName
#            Used to target all server instances in a cluster for tuning. Cannot be
#            used in conjunction with the -nodeName and -serverName options.
#         -templateFile
#            Determines which property file template to use for performance tuning.
