Ben and Brian,
First off, I'm sorry for the typo in my previous response. When running my
assertEquals() tests, I was actually running it on the re-retrieved POJO
objects (cachedPojoA, updatedPojoA, and updatedPojoB). Thank you for catching
that typo. :)
Good to know that doing a putObject() from both nodes isn't supported. That
explains part of the problem I'm seeing, but unfortunately not all. If I
follow the regular usage pattern, as you described:
cacheA.putObject("/test", pojoA); // pojo attached on cache A
|
| pojoA1 = cacheB.getObject("/test");
|
| pojoA.setBlah(xx); // will have problem here
| print(pojoA1); //will get updated.
pojoA1 won't exist on cacheB (I'll get a null value in this test). In the
logs, I'll see the object and values coming over to CacheB, but it won't
actually get set into CacheB.
As for the reason I'm doing a putObject() from both nodes ... each night, the
servers corresponding with CacheA and CacheB restart (various reasons behind
this) in about a 30 second staggered fashion. For this particular 'dailySpend'
data, we need to restore it from the database on server startup (lazy loading
isn't really an option here). One of the two servers needs to load it from the
database at startup, and because I'm never entire sure which one will complete
its startup first, I'm just having them both load the data from the DB. I'm
also afraid to code one server to be the primary DB loader (e.g., CacheA) and
the other to just retrieve the data across the network (e.g., CacheB) from the
other node because, if CacheA went down permanently, I'd have no way of loading
the data from the DB. I'm not sure if there's a way around this (any
suggestions would be appreciated) - I looked into your CacheLoaders, but they
didn't seem to fit. Perhaps I'm missing something??
Anyway, I still need figure out why replicated values aren't getting persisted
on the various nodes. :) I'm going to try JBoss Cache 1.4 and see if that give
me any different results. Could this be a configuration issue??
Thanks,
Michael
