Subject Re: DUCC Web Server Service Visibility and Default Reservations
Date Wed, 19 Jul 2017 20:25:50 GMT
Thanks Burn, looks like it is deployed but not healthy due to a refused RMI connection. The
web services page is refreshed, in addition to displaying no services it does not display
values for some other fields (Updated, Utilization) that are displayed on other web server

Any info appreciated, I'm not seeing anything more in sm.log than I am seeing here from the
ducc_services --query I ran. Both of the lines end at the number 38 for the MetaPid.

Did you refresh the Services page?  Ensure that the Users field is empty
(except for the hint)?  Also try $DUCC_HOME/bin/ducc_services --query

Reservations made by the "System" user are for internal use.
