Error description

  • After a "Start" of the IHS admin Server (adminctl start) there
    should be at least 3 processes running in UNIX:
    
     1 Root Process with parent of  1
     2 Root Process with Parent of another Admin.conf root process
     3 admusr process  which is the (User directive in the
       admin.conf)
    
    The output of "ps -ef | grep admin.conf" at the time of these
    failures reveals that the 2nd root process is gone.
    
    This process handles the adminSocket communication for the Start
    and Stop.  The problem is that the main Apache/IHS root parent
    process has no way of knowing that this root process is gone.
    

Local fix

  • The temporary solution is to restart the IHS Admin server
    (i.e. adminctl start).  However, better logging of this
    situation is needed.

    ****************************************************************
    WebSphere Application Server version 6.0.2 and 6.1 Web server
    status in the  Web server collection panel of the
    Administrative Console for Application Server has displayed
    incorrect status. The incorrect status was caused due to a
    timing failure between the request to stop the Web server and
    the acquistion of the Web server status. Changes have been
    made to add a loop to Web server status check.
    
    We have encountered a problem when the Special Administration
    Server root process has terminated yet the IBM Administration
    Server continues to run. We added changes to the IBM HTTP
    Server Administration Server Root Process to terminate the
    IBM HTTP Server Adminsitration Server in the Administration
    Server root process exit.
    We also encountered a problem where the IBM HTTP Server
    Administration Server has initialied yet the socket file,
    which is critical for the Start/Stop function of IBM
    Administration Server, has a fatal error. We have changed
    IBM HTTP Server Administration Server code so that IBM HTTP
    Server Administration will fail to initialize if the Socket
    file can not be created. Error messages will be written to
    the IBM HTTP Server Amdinsitration Server log.
    

Problem conclusion

  • This fix applies to both IBM HTTP Server version 6.0 and
    WebSphere Application Server version 6.0.2 or 6.1. However the
    patches are not dependent, meaning you can apply the fix to
    IBM HTTP Server and not apply to Application Server and
    the converse.
