DSPLY_NAME field issue

Pulaputra.Sudheer · 2025-01-31T11:17:22+00:00

There was an error rendering this rich post.

On the "REFRESH_RESP" item event, we can see there is the field "DSPLY_NAME" representing the Currency Pair in the response.

But on the subsequence "UPDATE_RESP" there was no "DSPLY_NAME" field anymore, only the rates and the dates.

How do we know if this "UPDATE_RESP" is for which item? How do we identify it?

I also have a question: What's the equivalent of "com.reuters.rfa.session.event.MarketDataItemStatus" in OMM?

Hello @Pulaputra.Sudheer

The item name is included in the encapsulated message and not in the fields which are updated. There are multiple means of identifying the instrument in RFA API callback method.

Assign a unique closure object to each subscribed item. The closure could be a string with the item name or any other identifier. This closure is available in the event callback for that particular subscribed item.

2. Get the item handle when subscribing. This item handle is subsequently available in the process event callback:

Handle itemHandle = _ommConsumer.registerClient(_eventQueue, connIntSpec, callbackClient, null);

and in the callback method:

public void processEvent(Event event) {  
   Handle itemHandle = event.getHandle();
   …

3. Request Attribute information in the update messages -

ommmsg.setIndicationFlags(OMMMsg.Indication.REFRESH | OMMMsg.Indication.ATTRIB_INFO_IN_UPDATES);

and the update messages will now contain the item name in the response:

Msg Type: MsgType.UPDATE_RESP
    Msg Model Type: MARKET_PRICE
    Indication Flags: DO_NOT_CONFLATE
    Hint Flags: HAS_ATTRIB_INFO | HAS_RESP_TYPE_NUM | HAS_SEQ_NUM

It should be equivalent to OMMState in the OMMMsg.

    static final void parseMsg(OMMMsg msg, PrintStream ps, int tabLevel)

    {



        if (msg.has(OMMMsg.HAS_STATE))

        {

            dumpIndent(ps, tabLevel + 1);
 ps.println("State: " + msg.getState());

        }
