Hello @jessie.lin

An update can be identified is for which RIC in OMMAttribInfo.Name component of an update message. This component requires OMMMsg.Indication.ATTRIB_INFO_IN_UPDATES is set on the request as described in Table 45: MarketPrice Update Message of RDM USAGE GUIDE - JAVA EDITION(RFAJ_RDMUsageGuide.pdf) shown below:

The example source code to set OMMMsg.Indication.ATTRIB_INFO_IN_UPDATES in an item request:

//set ATTRIB_INFO_IN_UPDATES IndicationFlags to receive RIC in AttribInfo of update message
ommmsg.setIndicationFlags(OMMMsg.Indication.REFRESH | OMMMsg.Indication.ATTRIB_INFO_IN_UPDATES);

//Set RIC
ommmsg.setAttribInfo(serviceName, itemName, RDMInstrument.NameType.RIC);

// Set the message into interest spec
ommItemIntSpec.setMsg(ommmsg);

//make subscription for the RIc
Handle itemHandle = _mainApp.getOMMConsumer().registerClient(_mainApp.getEventQueue(),ommItemIntSpec, _marketPrice, null);

An example update message including the RIC name:

    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
    SeqNum: 19486
    RespTypeNum: 0 (UNSPECIFIED)

        Name: XAU=
        NameType: 1 (RIC)

Hello @jessie.lin

To get the RIC name in the AttribInfo of an update message, you can use:

OMMMsg.getAttribInfo().getName()

For example:

OMMItemEvent ie = (OMMItemEvent)event;
OMMMsg respMsg = ie.getMsg();
System.out.println("This is update of a ric named " + respMsg.getAttribInfo().getName());
//print data

An example output:

Hi @jessie.lin

The most common practice is to pass the item name or RIC as enclosure object when calling the registerClient() method. For instance, we can modify the sendRequest() method in ItemManager.java file of the StarterConsumer example:

.
.
.
System.out.println(_className + ": Subscribing to " + itemName);
.
.
.
Handle itemHandle = _mainApp.getOMMConsumer().registerClient(_mainApp.getEventQueue(), ommItemIntSpec, this, itemName);

In the processEvent() method of the same itemManager.java file, simple call event.getClosure():

.
.
.
OMMItemEvent ie = (OMMItemEvent)event;
OMMMsg respMsg = ie.getMsg();
String itemName = (String) event.getClosure();
System.out.println("Item Name:" + itemName);
GenericOMMParser.parse(respMsg);
