Accounting/Billing Information in Database

The billing information which is normally written to /opt/d-cache/billing/ on the admin node will also be written to a database if config/dCacheSetup contains

billingToDb=yes

A PostgreSQL server is expected to run on the admin node with a database user “srmdcache” and a database “billing” with

[root] # createuser -U postgres --no-superuser --no-createrole --createdb --pwprompt srmdcache
[root] # createdb -U srmdcache billing

[return to top]

Space Reservation

The space reservation feature between the SRM and the GridFTP door may be switched on with

spaceReservation=true
