Hi - I can send off-stream posts into non-interactive service, or other services where the cacheLocation is srcApp

What do i need to enable in the source config on the ADH to enable Off-stream posting into an interactive source app

Thanks

Martin

    Thank you for reaching out to us.

    It also relates to the cacheType parameter.

    !++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    !
    ! ads${svc}*cacheType : sinkDriven
    !#help
    ! cacheType: { sinkDriven, sourceDriven }
    !
    ! sinkDriven - The cache content is determined by sink/network demand.
    ! A sink-driven server is allowed to add an item to its
    ! cache only upon the reception of an Open request.
    ! This type of server functions as an interactive datafeed
    ! handler and was formerly called a "Selective Cache" server.
    ! sourceDriven - The cache content is determined solely by the source
    ! application/ datafeed. Network demand has no bearing on
    ! the contents of the cache. A source-driven server is
    ! allowed to add an item to its cache at any time.
    ! This type of server functions as a broadcast datafeed
    ! handler and was formerly called a "Full Cache" server.
    !
    ! Default value: sinkDriven
    !#end

    For interactive providers, the cacheType should be sinkDriven. Moreover, interactive providers must support the posting feature by specifying it in the login refresh message.

    You need to check the API documents or examples regarding how to set it in the APIs. For example, if you use the EMA C++ to develop an interactive provider application, you can refer to the 340_MP_Posting example.
