  • Closed as program error.

Error description

  • When the AgentManager sends work to partitions, they are
    dispatched serially when a list of keys is provided.
    This APAR requests to have WebSphere eXtreme Scale send them
    out concurrently to increase throughput when using the
    AgentManager function. The eXtreme Scale dynamic cache
    plug-in implementation uses this AgentManager function for
    its invalidate function causing performance to be adversely
    affected.
