----------------------------------
Summary: DUCC Web Server (WS) non-DB case uses default Resource
Manager quantum only
Key: UIMA-4943
URL: https://issues.apache.org/jira/browse/UIMA-4943
Project: UIMA
Issue Type: Bug
Components: DUCC
Reporter: Lou DeGenaro
Assignee: Lou DeGenaro
Fix For: 2.1.0-Ducc
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.
