Process subscriptions. This must be invoked only once a day. Messages are only sent out when a collection has actually received new items, so that people's mailboxes are not clogged with many "no new items" mails.

Yesterday's newly available items are included. If this is run at for example midday, any items that have been made available during the current day will not be included, but will be included in the next day's run.

For example, if today's date is 2002-10-10 (in UTC) items made available during 2002-10-09 (UTC) will be included.

Parameters:

context - DSpace context object

test -

Throws:

SQLException

IOException
