---------------------------------
Let's keep the change in Shamim D only since we're so close to Code Freeze
> 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
> Assignee: johnwoodlock
> Fix For: Shamim D
>
>
> 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.
> 03/01/2011 5:18:45 PM
> org.apache.catalina.core.ContainerBase$ContainerBackgroundProcessor
> processChildren
> 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 account ids that are affected by the holiday change
> b) get 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.
