Abstract

Units Of Work (UOWs) for a financial balancing application are groups of monitory items which must conform numerically to some set of balancing rules. UOWs in the HPTS* Balancing Application are divided into smaller pieces called segments to facilitate parallel processing by multiple operators. Boundaries of the segments can change if the scope of the segmentation is altered or if an item controlling the segmentation within a segment is modified. This disclosure describes an indexing scheme and a data base structure capable of supporting significant change to segmentation boundaries with minimal overhead to other functions which are needed to reconcile the UOW during the ongoing balancing process.

Dynamic Re-Segmentation of Balancing Work with a Non-Volatile Keying
Structure

      Units Of Work (UOWs) for a financial balancing application are
groups of monitory items which must conform numerically to some set
of balancing rules.  UOWs in the HPTS* Balancing Application are
divided into smaller pieces called segments to facilitate parallel
processing by multiple operators.  Boundaries of the segments can
change if the scope of the segmentation is altered or if an item
controlling the segmentation within a segment is modified.  This
disclosure describes an indexing scheme and a data base structure
capable of supporting significant change to segmentation boundaries
with minimal overhead to other functions which are needed to
reconcile the UOW during the ongoing balancing process.

      Background Information and Definition of Basic Terms - The HPTS
Balancing Application uses a technique called segmentation to divide
a UOW (or string) into smaller pieces, called Segments of Work (SOWs
or just segments), so that multiple balancing operators, whose job it
is to reconcile one or more of these segments, can work in parallel
to balance the UOW.  Strings contain control tickets, debit items and
credit items.  Segmentation is done using the internal hierarchial
structure of the control tickets, which are, in decreasing scope, the
tracer, block, batch and sub-batch control tickets.  Segmentation
level is defined by selecting a one of these control ticket levels.
Each control ticket of that level and all the subordinate items form
a segment.  After the initial segmentation of a UOW, allowing the UOW
segment boundaries to be redefined (due either to a new choice of
control level for the segmentation or the modification of an item
controlling the segmentation within a segment) is called dynamic
re-segmentation.  This function was introduced with the HPTS
Balancing Application release 2.  It is this re-segmentation
technique and the underlying support of the technique to which this
disclosure pertains.

      Allowing Segment Boundaries to Change - There are several
operational and functional problems with once-only segmentation.
Some of the factors involved are:
  o  The scope may be to large or small.  Segment size is an
important
      consideration to throughput of the operators.  Among these are:
     -  Problems involved in allowing the workstation to receive
         large SOWs.  Performance is negatively affected when the SOW
         to be transmitted to the operator workstation are large.
     -  The inability of the operator to comprehend large SOWs.  If
         the operators are shown too large an area of the string they
         might be confused by many pages of items and transactions,
         slowing there completion of the segment.
     -  The inability of the operator to see proper scope to balance
         small SOWs.  If the operators...
