Abstract:
-
Clustering is one of the most effective means to enhance the
performance of object base applications. Consequently, many proposals
exist for algorithms computing good object placements depending on the
application profile. However, in an effective object base
reorganization tool the clustering algorithm is only one constituent.
In this paper, we report on our object base reorganization tool that
covers all stages of reorganizing the objects: the application profile
is determined by a monitoring tool, the object placement is computed
from the monitored access statistics utilizing a variety of clustering
algorithms and, finally, the reorganization tool restructures the
object base accordingly. The costs as well as the effectiveness of
these tools is quantitatively evaluated on the basis of the
OO1-benchmark.
