[ http://jira.jboss.com/jira/browse/JBAS-1601?page=history ]
Ole Husgaard updated JBAS-1601:
-------------------------------
Attachment: EntityBeanCacheBatchEagerInvalidatorInterceptor.java
Contributed eager batch cache invalidator
> Insufficient cache invalidation.
> --------------------------------
>
> Key: JBAS-1601
> URL: http://jira.jboss.com/jira/browse/JBAS-1601
> Project: JBoss Application Server
> Type: Feature Request
> Components: EJBs
> Reporter: Ole Husgaard
> Priority: Minor
> Attachments: EntityBeanCacheBatchEagerInvalidatorInterceptor.java
>
>
> We have a CMP2.0 bean with some extra persistent state that the CMP engine
> cannot handle. To ensure that the extra state is saved to persistent storage
> we use call-ejb-store-on-clean=true to ensure that ejbStore is called as the
> spec requires. So far no problem.
> The problem comes when we use this bean in a clustered environment (commit
> option B) and do the dual-deployment RW/RO pattern with cache invalidations.
> In this case a cache invalidation is not sent out from the RW deployment to
> the RO deployment if the only persistent state changed is the non-CMP-managed
> persistent state.
> To get around this problem we have written a new interceptor
> EntityBeanCacheBatchEagerInvalidatorInterceptor. Replacing the standard
> EntityBeanCacheBatchInvalidatorInterceptor with this interceptor ensures that
> cache invalidation messages are always sent unless the bean is read-only, or
> the entity method call is read-only.
> I will attach this interceptor written for 3.2.6 (ie. a contribution).
> I would like this - or something similar - to be part of future JBoss
> versions.
