APAR status

  • Closed as program error.

Error description

  • If the node agent is stopped before the webserver, then when the
    node agent restarts, it will start the webserver.  This is
    because the node agent creates a default monitoring policy for
    webservers since these servers do not have one defined.  For
    this type of server a value of STOPPED should be used for
    nodeRestartState rather than the default of PREVIOUS.
    

Local fix

  • Stop the webserver before the node agent is stopped
    

Problem summary

    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server Network Deployment V6.1 and V8.0 on  *

    * PROBLEM DESCRIPTION: At nodeagent startup, the nodeagent     *

    * RECOMMENDATION:                                              *
    ****************************************************************
    During nodeagent startup, it checks the monitoring policy of
    servers on its node. A webserver or Generic server use the
    default monitoring policy which has a NodeRestartState of
    PREVIOUS. If the webserver was running at the time the
    nodeagent was stopped, the nodeagent saves that fact for when
    the nodeagent is restarted.  At nodeagent restart with the
    NodeRestartState of the webserver as PREVIOUS, the previous
    state of the webserver was saved as STARTED, so the nodeagent
    restarts the webserver. If the webserver is not running when
    the nodeagent is stopped, then at nodeagent restart, the
    nodeagent  will not try to start the webserver because the
    previous state of the webserver was saved as STOPPED.
    

Problem conclusion

  • The nodeagent code was modified for webserver or generic
    server on z/OS to have a NodeRestartState of STOPPED.
    So regardless of the webserver's previous state, the nodeagent
    will not try to start it.
    
    APAR PM51744 is currently targeted for inclusion in Service
    Level (Fix Pack) 6.1.0.43 of WebSphere Application Server V6.1
    and Fix Pack 8.0.0.3 of WebSphere Application Server V8.0.
    
    The fix will also be delivered as sysrouted APAR PM53578 in
    WebSphere Application Server V7.0 Fix Pack 7.0.0.23.
