Error description

  • The issue was during migration from WAS V6.1 to WAS V7. Customer
    had the following variables defined at cell scope:
     DB2UNIVERSAL_JDBC_DRIVER_NATIVEPATH=/usr/lpp/DB2/lib"
    The above variable did not exist at any lower level (node or
    server). During migration, the cell scope setting was properly
    carried over, but also added the same variable at each node
    scope and set it to null:
     DB2UNIVERSAL_JDBC_DRIVER_NATIVEPATH=<blank>
    
    Since node scope setting takes precedence, the applications
    connection to DB2 were broken.
    

Local fix

  • remove node scope definition for
    DB2UNIVERSAL_JDBC_DRIVER_NATIVEPATH

    * RECOMMENDATION:                                              *
    ****************************************************************
    Customer may have cleaned up the node or server level blank
    variables in the older release and set these variables at a
    higher scope.  Once migrated the Default profile template
    resets these blank variables at the node and server levels.
    These defaul blank variables override the values set at the
    higher scope.
    

Problem conclusion

  • This fix tests for the existance of blank level variables in
    the new profile and if the corresponding variable is not
    also set to blank at the same scope in the old profile being
    migrated the default blank variables are removed from the new
    profile.  If the blank variable is set and overrides the same
    variable at a higher scope a Warning is issued.
