Error description

  • An IBM MQ-MFT agent running on AIX at version is
    migrated to version by upgrading the MQ
    installed packages to MQ
    Then when an attempt is made to start the agent, the following
    error message is seen in the output0.log file:
    BFGBS0005E: An internal error has occurred.  The exception
    details follow this message.

      at sun.reflect.NativeMethodAccessorImpl.invoke
      at sun.reflect.DelegatingMethodAccessorImpl.invoke
      at java.lang.reflect.Method.invoke
    Caused by: java.lang.NoClassDefFoundError:
    The agent does not start and is subsequently unable to perform
    any file transfer activity.

Local fix

  • The primary recommended upgrade mechanism to avoid this issue is
    to completely uninstall all of the filesets of the older version
    of MQ first, prior to installing the newer MQ v9.0.0.0 or later
    filesets on AIX.
    Alternatively if you have already migrated to the MQ v9.0.0.0 or
    later filesets, this issue can be resolved by uninstalling and
    reinstalling the MQ Managed File Transfer components when
    migrating the installation.
    The uninstall and re-install of the affected components can be
    achieved by running the following commands:
    Note: the install commands should be run from within the
    directory where the install packages are located, or adjust the
    commands accordingly.
    installp -u mqm.ft.base mqm.ft.agent mqm.ft.logger
    installp -acgXYd . mqm.ft.base mqm.ft.agent mqm.ft.logger
    If MQ is installed in non-default location, then use the
    following commands:
    installp -R <USIL_Directory> -u mqm.ft.base mqm.ft.agent
    mqm.ft.logger mqm.ft.service
    installp -R <USIL_Directory> -acgXYd . mqm.ft.base mqm.ft.agent
    mqm.ft.logger mqm.ft.service

Problem summary

  • ****************************************************************
    This issue affects users of the IBM MQ Managed File Transfer
    components on AIX, who are migrating an installation prior to
    v9.0.0.0, to v9.0.0.0 or later.
    Platforms affected:
    At versions of IBM MQ Managed File Transfer prior to v9.0.0.0,
    the .jar file:
    was supplied as part of the "mqm.ft.agent" install component on
    AIX.  In order to satisfy a product dependency on an install
    component,  this .jar file was relocated to another install
    component at IBM MQ v9.0.0.0.  On the AIX platform, the IBM MQ
    component where the file was moved to is called: "mqm.ft.base".
    The migration installation mechanism offered by AIX may result
    in files being lost when files are moved between filesets,
    depending on the order in which the filesets are upgraded.
    If the first component which is upgraded is "mqm.ft.base" which
    contains the new version of the
    "" file, then when  the
    second component is subsequently upgraded (mqm.ft.agent), the
    file is removed as part of the older component's removal
    procedure, prior to the installation of the updated package.
    When this happens, a warning message is output as part of the
    upgrade process, which reads:
    installp: APPLYING software for:
            mqm.ft.base (R)

    sysck: 3001-036 WARNING:  File
            is also owned by fileset mqm.ft.agent.
    This warning message was displayed indicating that the now belonged to two
    components, mqm.ft.base and mqm.ft.agent components.
    After this, as part of upgrading mqm.ft.agent, it uninstalled
    the mqm.ft.agent component, which resulted in its associated jar
    files including "" being
    deleted.  This .jar file was then not reinstalled as part of the
    mqm.ft.agent fileset installation, as this .jar file is no
    longer associated with that fileset.

Problem conclusion

  • The install scripts for the filesets have been updated to
    prevent the problem was occurring.
    The fix is targeted for delivery in the following PTFs:
    Version    Maintenance Level
    v9.0 CD    9.0.5
    v9.0 LTS
    The latest available MQ maintenance can be obtained from
    'WebSphere MQ Recommended Fixes'
    If the maintenance level is not yet available information on
    its planned availability can be found in 'WebSphere MQ
    Planned Maintenance Release Dates'
