Description

When DUCC is configured to not use database (not recommended, but allowed) the Web Server (WS) may not display Machines page data correctly in the case where the system is configured to use multiple share size quanta.

Nominally, the Resource Manager (RM) places the data needed by the Web Server to properly display the Machines page into the database. However, in the non-DB case, this is information is not shared by the RM and thus the WS must divine the needed information. As a minimal solution that works in many cases, the WS reads the default ducc.rm.share.quantum size from ducc.properties and employ same universally.

A complete solution would be for the WS to independently do the identical calculations that the RM does with respect to multi-quanta. Presently it does not do so, and thus this is a known limitation.
