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.

Armin
Thanks again, and again...

Now, my need would be to getAllBroker from

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.
