    in special notes section of fixpack readme.txt they mentioned this that mentioned that u may loose control center functionality.

    but I do not understand their suggested fix section. Can some one please throw some light on it.(Version 7 clients must be upgraded to FixPak 2 or later). I already have installed fixpack 3.


    thank you

    2.7 Special Notes

    2.7.1 Loss of Control Center Functionality

    There should be no problems introduced against downlevel Control Center
    clients by applying FixPak 2 to a DB2 server. However, with this FixPak and
    in DB2 Version 7.2, downlevel Control Center clients will lose nearly all
    functionality. Downlevel in this case refers to any Version 6 client prior
    to FixPak 6, and any Version 7 client prior to FixPak 2. Version 5 clients
    are not affected.

    The suggested fix is to upgrade any affected clients. Version 6 clients
    must be upgraded to FixPak 6 or later, and Version 7 clients must be
    upgraded to FixPak 2 or later.
