What all things to keep in mind with respect to jBPM3 in SOA-P while removing clustering features ?

Solution Unverified - Updated -

Issue

  • In the process of removing clustering from the SOA-P 5.x nodes , is there any point to following the instruction from this KCS [1] and forcing jBPM 3 to use JBoss Cache v/s the default org.hibernate.cache.HashtableCacheProvider as 2nd level cache provider for jBPM when the nodes are not clustered?
  • If some users did configure JBoss Cache instead would they need change the jbpm.esb/hibernate.cfg.xml file to use MVCC instead of OPTIMISTIC node locking as mentioned in this KCS [2] in such a scenario?
