the blasadmin commands need to run against 'all' or the specific instance you are trying to enable webservices on. you can (and should) run it against _template but that only sets the defaults for newly created instances and won't affect any existing instances.
Understood, when I switched to the deployment that I want to enable it on, I get this:
blasadmin now running against deployment: job_deployment_1_nodcaptbmc14
bladmin:job_deployment_1_nodcaptbmc14>set AppServer enableWebServices true
Unable to find storage for EnableWebServices
I don't know what "Unable to find storage for EnableWebServices" means and how to correct it
Webservices can only be enabled on CONFIGURATION and ALL profile types. not JOB or NSH_PROXY.
