V5.x: Node agent does not start
 Technote (troubleshooting)
 
Problem(Abstract)
Node agent does not work in WebSphere® Application Server 5.0.
 
Resolving the problem
  1. Make sure the node agent is added to the Network Deployment Manager. Open a console connected to the Network Deployment Manager and verify that the node agent is in the System Administration > Node Agent list. Also, check the icon in the Status column to see what the Network Deployment Manager reports for the state of the specific node agent.

  2. See if that node agent is running. Go to the machine that has the node agent in question, WAS_HOME/AppServer/bin directory for that node, and from a Windows® command prompt run serverstatus -all, or on UNIX® ./serverstatus.sh -all. The output indicates what the machine is running.

  3. If Steps 1 and 2 both state that the node agent is not started, but it is added to the Network Deployment Manager, from a Windows command prompt run startnode or on UNIX ./startnode.sh in the WAS_HOME/AppServer/bin directory for that specific node.

  4. Verify that the ports are not in use by something else on the node agent machine by issuing a netstat -an. Look for the ports that the node agent uses.
    1. Open WAS_HOME/ND or Base/config/cells/Cell Name/nodes/node name/serverindex.xml file.
    2. Search for nodeagent and you should find this xml tag: <serverEntries...>.
    3. Between the <serverEntries...>. and </serverEntries> tags, search the netstat output to verify that all the ports listed are open.

  5. If the problem is still not resolved, look at the stdout and stderr logs for the node agent to see what they are stating. These files and others for the node agent are located in the WAS_HOME/AppServer/logs/nodeagent directory.

  6. If nothing else works call IBM support at 1-800-IBM-SERV.
