    If Elasticity Mode is enabled for Application Placement
    Controller (APC) and memory overload protection (MOP) is
    triggered, APC fails to add additional nodes to the dynamic
    cluster.
    

Problem conclusion

  • When memory overload protection (MOP) is triggered in elasticity
    mode, APC will now consume that information and update the
    cluster capacity accordingly to add additional node(s) to the
    cluster if resources are available and min/max criteria is not
    violated.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 8.5.5.10.  Please refer to the Recommended Updates page for
