Adding 50,200 Entries to a DCE Namespace: A Comparison of OSF DCE V1.0.2 and IBM DCE/6000 V1.2

摘要

This study compares two releases of the Distributed Computing Environment (DCE) during the addition of 50,200 server entries to the cell namespace. To conduct the study, we configured a one-machine cell with DCE core services (RPC facility, initial security server, primary CDS server, and DTS local server). The study focuses on the cdsd paging space, CDS file space usage, and cdscp response time. Although resource consumption increases linearly with the number of users added to the cell namespace, cdscp response time increases markedly during a CDS checkpoint operation. The CDS performance statistics included in this study enable the DCE administrator to establish a resource usage baseline. However, further investigation is required to ascertain whether CDS server replication will smooth the cdscp response time or exacerbate cdscp delays.
