Login Domain - Components and Elements in Login responses

The below question is related to sections 3.2.4 and 3.2.5 of EMA30_RMD Usage Guide;

The Login Refresh and Login Status messages of the Login Domain consist of a number of components and attributes E.g. AllowSuspectData, SingleOpen.

a) Out of these what components and attributes should mandatorily be consumed by the consuming application?

b) Is it acceptable for the consuming application to not process (i.e. ignore) non-mandatory fields available in the Login Refresh or Login Status messages.

c) Is it possible for consuming application to receive values that are out of range for a particular element; e.g. Expected values for the element AllowSuspectData are either 0 or 1. Is it possible that the consumer application to receive any value other than 1 or 0 (invalid values), may be due to a defect of omm provider.

  • Please see the following answers to your questions.

    a) The Login domain is one of the Reuters Domain Models
    (RDMs) which typically are provided or consumed by a Thomson Reuters product, such
    as the Enterprise Platform Real-Time, Data Feed Direct, or Elektron. If the
    consuming application connects to one of Thomson Reuters product, there should
    be no other components and attributes received.

    b) The Login is administrative
    domain which is generally handled by EMA. Application doesn’t need to process
    the Login domain message. However, Login message processing provides additional information about the connected provider.

    For example, if an OMM provider
    doesn’t support Dynamic View feature, it will send SupportViewRequests = 0 in
    the Login refresh message. Once EMA applcation tries to use Dynamic Views
    feature by specifying field ID Element List in ReqMsg’s payload, EMA will
    process the request depended on received value of the SupportViewRequests. If
    SupportViewRequests is 0, EMA will send the request message without views so
    that the application receives refresh with all available fields. In this case,
    Login refresh processing will provide the reason why Dynamic Views request
    doesn’t take effect.

    c) If OMM provider actually sends
    the out of range values, EMA application will also receive the values. This is
    because EMA pass the values received from network to application as is.

  • Please tell me this will work in conjunction with domain catcher? The fact that I recently bought, it helps my work, but I'm not sure whether it will work with your service, decided to find out in advance.
