    Hi @pavel.kropachev

    DACS OnDemand can be licensed and enabled at the DACS server level.

    From a programming perspective there is no difference in terms of using your RFA or Elektron APIs.

    If, however, you are using OpenDACS to implement permission/entitlement checks etc, then by default any Subscription checks you perform will be with OnDemand being indicated. If you wish to make a subscription check without OnDemand then you can use OpenDacs v7.5 or higher which exposes an additional considerDOD parameter to disable OnDemand in the checkSubscription call.

    For example code please download the relevant OpenDACS SDK (C++/Java/.NET) and refer to the examples e.g. dacsSubscribeClient
