Cache Invalidation - BMP Entity bean is getting invalidated
My application has clustered remote SLSBs with "FirstAvaliable" policy.
The BMP Entity Beans are set for cache invalidation only as they exist at local level only. They are not set for any clustering.
I am using Commit Option A.
I want cache to invalidate bean on all nodes except the node it was accessed from.
Here the cache is being cleared even on the node it was last accessed from.
I executed a business method on the same node (due to FirstAvailable) and here is the list of methods encountered.
setEntityContext
ejbFindByPrimaryKey
ejbActivate
ejbLoad
getAllAccounts
ejbStore
setEntityContext
ejbActivate
ejbLoad
getAllAccounts
ejbStore
setEntityContext
ejbActivate
ejbLoad
getAllAccounts
ejbStore
My expectation is that second and third time, in addition to my business method, only ejbLoad and ejbStore should be executed.
After info from guides and forum topics, I have configured as under :
cluster-service.xml
============
I am using the default behaviour of JBoss-Cluster based bridge
jboss.cache:service=InvalidationManager
${jboss.partition.name:DefaultPartition}
DefaultJGBridge
jboss:service=${jboss.partition.name:DefaultPartition}
jboss.cache:service=InvalidationManager

Uncomment if you want to activate the cache invalidation mechanism accross
nodes using the JMS bridge
PropagationMode can be : IN_OUT = 1, IN_ONLY = 2, OUT_ONLY = 3
You can also set the ProviderUrl attribute to another IP:port setting if you
must lookup your JMS information in other JMS trees i.e.
MyOtherNode:1099
