ApplyHolidayChangesTask batch task falls over if too many schedules to be
updated
---------------------------------------------------------------------------------
Key: MIFOS-2735
URL: http://mifosforge.jira.com/browse/MIFOS-2735
Project: mifos
Issue Type: Bug
Components: Batch jobs
Affects Versions: Release 1.4
Reporter: johnwoodlock
Task takes new holidays and adjusts any schedules it needs to.
Problems
1. When testing GenerateMeetingsForCustomerAndSavingsTask with a large dataset,
it fell over with a java heap exception. There were a large number of
schedules that would have had to be adjusted and it was too much for it to
handle. Note, I had set my date way in the future for testing purposes.

SEVERE: Exception invoking periodic operation:
java.lang.OutOfMemoryError: Java heap space
I think this task may need to be changed to how other batch jobs currently work
(using batch size and commit frequencies to break up the work):
a) get back all accounts id that are affected by the holiday change
b) bet the account and adjust its schedules
c) commit every X customer accounts.
2. The task only updates savings and loans schedules (not customer schedules).
Not a problem for GK or any other client that doesn't use holidays.
Not a problem if the holidays are defined well in advance so that no schedules
need to be adjusted.
I haven't tried to fix this batch task myself because
1) It doesn't affect GK (no holidays defined) and so is not a scalability issue
just yet (that's what I'm working on at the moment)
2) Keith W and Keith P are working in that area currently so I just wanted to
document this problem.
