Appeal No. 2001-1605
Application 08/735,168
Global Compatible Class Locking, Bireley discusses the problem of
parallel tasks causing contention on locking database resources
during the processing of the query. See column 22, lines 31
through 33. Bireley teaches that it is imperative that shared
database management systems treat all locking requests resulting
from the parallel task of a query as belonging to the same
family. Under such a scheme, one parallel task executing on one
database management system can share database resources with
other parallel tasks distributed across the database management
systems. Bireley discloses that figure 11 describes global
compatible class locking of the invention. Bireley uses a
globally compatibility token as a key for locking and unlocking
database resource along parallel tasks of a query.
From our review of Bireley, we fail to find that the
Examiner has established that Bireley teaches locking a partition
of a table in a database having a plurality of partitions. The
only portion of Bireley that discusses locking does not teach or
suggest locking only a single partition of a table having
multiple partitions. Bireley only teaches about locking in
columns 22 and 23. The portions that the Examiner relies on for
partitioning is addressing a completely different problem.
Therefore, we will not sustain the Examiner’s rejection.
