Error description

  • Setting the dynamic cache customer property
    com.ibm.websphere.xs.dynacache.disable_recursive_invalidate to
    "true" causes the cache instance to not be created when
    WebSphere eXtreme Scale is specified as the dynamic cache
    provider.
    
     The following warning appears in the logs:
    CWOBJ0006W: An exception occurred:
    com.ibm.websphere.objectgrid.ObjectGridRuntimeException:
    Recursive invalidation has been depricated and is no longer

    ****************************************************************
    By default, recursive invalidation for dynamic cache
    instances is disabled. However, if you set the
    com.ibm.websphere.xs.dynacache.disable_recursive_invalidate
    custom property to true to disable the invalidation, a warning
    message displays in the logs. The map in the data grid that
    corresponds to the dynamic cache instance is not created.
    

Problem conclusion

  • The code has been fixed to display this warning only when the
    custom property is set to false.  The deprecated
    recursive invalidation function is enabled.
