What setting is needed to allow the number of data stream opens for an adh service to increase to an expected large number?

The adhmon shows in the Data Streams page, opens can only reach to about 500000, although the client subscribes for a million or more. The client also gets a lot of status messages

Text: "F6: Cannot Preempt Item"

Text: "F7: Item Preempted")

So that even though the normalRequests can increase, but data stream opens can only stay to about 500000. The Interactive Provider is a C++ application with RFA.

It could be maxCache configuration in ADH or the OpenLimit sent by the interactive provider.

    maxCache:


    This parameter allows to override/lower the maximum cache size
    supported by a source application on TREP. If no value is specified,
    then the application specified open limit will be used by the ADH.


    Note: This parameter must be specified, if it is not provided
          programmatically by the source application.


    Default value: NONE - OPTIONAL

OpenLimit is in the RFA RDM usage guide. maxCache is in the ADHCPD_Install_Supplement document.
