Re: How to release cached objects ?
Hi Bruno, Bruno CROS wrote: Hi Armin, thank you for answering so quickly. That's always very nice. Sorry, but I have 3 more questions about clearing Object Caches : - When PersistenceBrokerFactory.releaseAllInstances is done, does Object Caches are reset? Nope. - Can, either of these ways to clear cache ( PersistenceBrokerFactory.releaseAllInstances (if it is so) and PB.clearCache ), damage running transactions using released cached objects ? I think the PersistenceBrokerFactory.releaseAllInstances could prevent running PB instances to release itself back to pool (but OJB will catch this exception). The PB.clearCache() shouldn't affect other running tx (but I never wrote a test to verify this). - If I choose the PB.clearCache(), how can i iterate *all* the PBs i have in my pool ? I can get one PB from the pool, but i don't known how to get the whole collection. PB.clearCache() will clear all used caches (because all implementations shipped with OJB use a static map to manage the cached objects). But the session caches of other running PB instances are not cleared (when using the two-level cache). Anyway I recommend to write a simple test to verify me answer to play it safe. regards, Armin Thanks again, and again...

Hi Bruno, Bruno CROS wrote: Hi, Just about a little question. Does PersistenceBrokerFactory.releaseAllInstances() release all cached objects? I'm using PersistenceBrokerFactoryDefaultImpl and ObjetCacheDefaultImpl (and OJB 1.0.4.) The goal is to force server to reload all OJB mapped objects. Is there a proper foreseen method to call to do this? Evict all caches: PB.clearCache() or PB.serviceObjectCache().clear() With PersistenceBrokerFactory.releaseAllInstances() you will release all pooled PB instances and reset the the PB pool. regards, Armin Thanks a lot.
