Starting listener ports using scripting

These steps demonstrate how to start a listener port on an application server using scripting.

1. Identify the listener port MBeans for the application server and assign it to the lPorts variable.
   • Using Jacl:

     set lPorts [$AdminControl queryNames type=ListenerPort,
     cell=mycell,node=mynode,process=server1,*]

   • Using Jython:

     lPorts = AdminControl.queryNames('type=ListenerPort,
     cell=mycell,node=mynode,process=server1,*')
     print lPorts

   Example output:

   WebSphere:cell=mycell,name=ListenerPort,mbeanIdentifier=server.xml#
   ListenerPort_1,type=ListenerPort,node=mynode,process=server1
   WebSphere:cell=mycell,name=listenerPort,mbeanIdentifier=ListenerPort,
   type=server.xml#ListenerPort_2,node=mynode,process=server1

2. Start the listener port if it is not started. For example:
   • Using Jacl:

     foreach lPort $lPorts {
          set state [$AdminControl getAttribute $lport started]
          if {$state == "false"} {
             $AdminControl invoke $lPort start
          }
       }

   • Using Jython:

     # get line separator 
     import  java
     lineSeparator = java.lang.System.getProperty('line.separator')
     
     lPortsArray = lPorts.split(lineSeparator)
     for lPort in lPortsArray:
     	state = AdminControl.getAttribute(lPort, 'started')
     	if state == 'false':
     		AdminControl.invoke(lPort, 'start')

   These pieces of Jacl and Jython code loop through the listener port MBeans. For each listener port MBean, get the attribute value for the started attribute. If the attribute value is set to false, then start the listener port by invoking the start operation on the MBean.
