    Two new features are provided for IBM DB2 Analytics
    Accelerator.
    1. Workload Balancing will automatically route the
       query to the most appropriate accelerator based
       on the accelerator utilization. DB2 will collect
       the capacity and utilization statistics for each
       accelerator via hearbeat, then calculate which
       accelerator the query should be routed to so that
       the workload will be balanced dynamically among
       all the accelerators.
       Workload Balancing requires:
            IBM DB2 Analytics Accelerator server level
            of at least version 4, and
            Stored procedure Support level of at least 3
    2. System-level Monitoring provides the user enhanced
       statistics trace (IFCID 2) collection of acceleration
       activities.  There are new counters introduced in the
       Q8ST data section that collect acceleration activities.
    
       Also there are existing counters which have been marked
       as serviceability in the Q8ST data section, which are
       kept for compatibility with prior IBM DB2 Analytics
       Accelerator versions.  The values in these fields may
       not be accurate when running with IBM DB2 Analytics
       Accelerator Version 4.  The new mapping of the Q8ST
       is compatible with prior versions of IBM DB2 Analytics
       Accelerator.
