Default value and behavior changes in v9.0

Function area What changed v9.0 Previous versions
High availability and workload management
Core group custom property: IBM_CS_OOM_ACTION Isolate No default value
Cell cluster custom property: IBM_CLUSTER_REUSE_ORIGINAL_IOR True No default value
Proxy server setting: High availability monitor timeout 0 300
Core group member default protocol selection Core group member communication defaults to using the highest protocol version. Lowest protocol version used
Resources JPA data source error handling A misconfigured <jta-data-source> or <non-jta-data-source> element in the persistence.xml file associated with an EntityManager or EntityManagerFactory object must be fixed or removed. If the product tries to access a misconfigured <jta-data-source> or <non-jta-data-source> element in the persistence.xml file associated with an EntityManager or EntityManagerFactory object, the product issues a CWWJP0013E error message and then ignores the misconfigured data source.
