Cache Invalidation fails when redeploy CMP beans ------------------------------------------------ Key: JBAS-973 URL: https://jira.jboss.org/jira/browse/JBAS-973 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering, EJB2 Affects Versions: JBossAS-3.2.6 Final Reporter: SourceForge User Assignee: Brian Stansberry Fix For: Backlog SourceForge Submitter: coneheed . Java version: 1.4.2_04,Sun Microsystems Inc. Java VM: Java HotSpot(TM) Client VM 1.4.2_04-b05 ,Sun Microsystems Inc. OS-System: Windows 2000 5.0,x86 We have in place a clustering architecture as described in the JBoss clustering book. It currently consists of 3 nodes. 2 "read-only" nodes whose CMP entity beans have read-only accessor methods and a "read-write" node where the entity beans have "read-write" accessor methods. We use the cache invalidation architecture (based on JGroups) to link the read-only and read-write beans together. Changes to the RW beans cause invalidation in the RO beans and the data remains consistent. This all appears to work fine until we redeploy our application jar files. The system continues to function but we get out of date data in our RO beans. Basically the RO beans are not asked to ejbLoad and hence re- read the data from the DB. Bounce all 3 nodes and the system works fine again. Redeplying to the RW node is OK but redeploying to the RO node breaks the cache invalidation.
