Error description

  • This issue addresses two performance/hang issues with the
    Profile Management Tool (PMT) for WebSphere Application Server
    V7.0.  The Profile Management Tool may hang on startup, or it
    may display graphics very slowly and hang for several minutes
    when displaying certain panels.
    
    When starting the Profile Management Tool, it may hang without
    displaying any graphics at all, or it may display an
    introductory splash screen and then hang.  This can occur when
    running certain Xwindows window managers (or when running no
    window manager at all).
    
    If the Profile Management Tool starts successfully, it may draw
    the graphics on each wizard panel very slowly.  On certain
    wizard panels, it may hang for several minutes without drawing
    any graphics at all, and it does not accept input until the
    drawing is complete.  Sometimes, the hang does not resolve at
    all.  This can occur when running Xwindows over a remote
    connection where the network latency is over 30 milliseconds.
    
    The hang is most noticeable when using the Profile Mangement
    Tool to create a new profile.  After choosing the profile type
    (profile template), the wizard will begin drawing the panel to
    prompt for the profile creation type.  The text "Typical Profile
    Creation" will appear, and then the drawing will hang for
    several minutes before the rest of the text appears.
    
    The issues described above are related to defects in Eclipse
    libraries shipped with the Profile Management Tool.  The
    technical details of these defects are described in Eclipse
    Bugzilla Bug 305991 and 36086.
    
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=305991
    https://bugs.eclipse.org/bugs/show_bug.cgi?id=36806
    
    The "hang on startup" issue has been reported on AIX 64-bit
    systems, whereas the "slow performance and hang" issue has been
    reported on both AIX 32-bit and AIX 64-bit systems.  (Note that
    the Profile Management Tool is only available for the 32-bit
    edition of WebSphere Application Server V7.0 on AIX.)
    

Local fix

  • As a workaround, consider using the command-line
    "manageprofiles.sh" tool to create and manage profiles.  The
    manageprofiles.sh tool avoids the graphics-related issues
    entirely.
    
    If it is necessary to use the graphical tool, the following
    workarounds mitigate the hang and performance issues:
    
    - Try to use a different Xwindows window manager.  For example,
    instead of using an Xwindows product on Microsoft Windows, try
    using the Xwindows capabilities on a Linux or Unix system.  When
    using Cygwin XFree86 on Microsoft Windows, try an alternative
    window manager to the "multi-window" window manager.
    
    - Try to use the Profile Management Tool on a local system with
    a display attached.
    
    - When connecting to a remote system using Xwindows, try to
    connect from a location with as little latency as possible
    between the client and server.
    
    - When using the profile tool, try not to allow any other window
    draw on top of the profile tool windows.  This increases the
    window drawing time.

    * PROBLEM DESCRIPTION: PMT runs slowly on AIX. It happens      *
    *                      only on 64bit while using Reflection X. *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The software launches fine but hangs as soon as any button
    (or link) is clicked. The INDERTERMINATE progress bar is
    flooding the event queue with timer events causing application
    hang. The code inside the timer takes about 100 milliseconds
    to run on this system and the progress update timeout is 100
    milliseconds as well.
    

Problem conclusion

  • This patch adjusts the progress update timeout according to
    how long it takes to run the code. When there is no window
    manager running or the window manager is rootless, and the
    parent window containing the window frame is a native window,
    not an X window, no reparent occurs. isVisible() fails for an
    unparented Shell, so the application hangs after verifying if
    the Shell has become visible. The patch reacts to specific X
    event, and once it happens,the window is treated as parented
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.15  Please refer to the Recommended Updates

Temporary fix

  • Using manageprofile command to create profiles.
