Getting "Cannot request snapshot batch or dynamic view due to unavailable SNAP_AND_DYNAMIC_VIEW l...

...icense" error via Websocket API

Hi everyone,

I'm trying to get market data prices via WebSocket API. While i'm trying to reach to the datas i get "Cannot request snapshot batch or dynamic view due to unavailable SNAP_AND_DYNAMIC_VIEW license" error as i said above. Why am i getting this error? I'm using the 'View' feature of the API and I added "BID" and "ASK" values to the View which i need the market price of.

Here's my response:

[{"ID":1,"Type":"Status","Key":{"Service":"IDN_RDF","Name":"TRY="},"State":{"Stream":"Closed","Data":"Suspect","Code":"AlreadyOpen","Text":"Request Rejected: Cannot request snapshot batch or dynamic view due to unavailable SNAP_AND_DYNAMIC_VIEW license."}}]

Thanks.

@sabri demirel: This issue has been fixed in ADS 3.2.1.L1. Please upgrade your TREP infrastructure and try again.

Hi @betul.simsek, ADS requires additional license for providing dynamic views. Can you please check with your market data administrator, if this is enabled on your ADS.

betul.simsek

Hi @Gurpreet,

As you said we've licensed our servers and tried again. But now we're getting another error. Our request and reponse messages are below. Can you check and tell us what's wrong with our request?

Thanks a lot.

request:

{"ID":1,"Domain":"MarketPrice","Key":{"Name":"TRYTOM=D3","Service":"IDN_RDF"},"Streaming":true,"View":["BID","ASK"]}

reponse:

[{"ID":1,"Type":"Status","Key":{"Service":"IDN_RDF","Name":"TRYTOM=D3"},"State":{"Stream":"ClosedRecover","Data":"Suspect","Text":"Json conversion error."}}]

I tried submitting this request after modifying for our infrastructure and got following response:

Are you using the latest WebSocket API? Try this with the sample applications in downloads package.

Gurpreet

If you are using one of the example applications, can you please tell which language you are using.

@betul.simsek

Can you change the ID of MarketPrice request to 2?

Basically the ID was designed for representing the event stream. It can also be used to match the request and responses. Our example use ID 1 for Login request so if you set the same ID for MarketPrice request it may cause the issue.

I did quick test your json data with node.js example market_price_batch_view.js and change the ID to 2 and it works like Gurpreet said.

sabri demirel

Hi @Gurpreet @moragodkrit.chumsri_1

We set ID to 2 but the response is same .

Our request:

{"ID":2,"Domain":"MarketPrice","Key":{"Name":"TRYTOM=D3","Service":"IDN_RDF"},"Streaming":true,"View":["BID","ASK"]}

Response:

[{"ID":2,"Type":"Status","Key":{"Service":"IDN_RDF","Name":"TRYTOM=D3"},"State":{"Stream":"ClosedRecover","Data":"Suspect","Text":"Json conversion error."}}]

It like a json conversion error. Can you check the Reuters server which we connect can parse our request?

Gurpreet

You didn't provide all the information. Which language are you using, and did you build the application or using one of the samples.

Here is the response in NodeJS - market_price_batch_view.js

Hi @Gurpreet

We are using sample code. It is written with Java script. You can find the code as attached.tr-websocket.zip

In websocket , is the language important? when we connect another websocket suppliyer (eg Foreks), we can use javascript or c#.

Additionally, When I changed the RIC to USD I receive

[{"ID":1,"Type":"Status","Key":{"Service":"IDN_RDF","Name":"USD"},"State":{"Stream":"Closed","Data":"Suspect","Code":"NotEntitled","Text":"Record not service permissioned"}}]

I think Reuters websocket server can not resolve '=' char. Bu all of the RICS which we are using include '=' char.

Gurpreet

There is no source code in the zip file that you attached.

Like I mentioned in the previous reply - the Javascript market_price_batch_view.js example with TRYTOM=D3 is able to successfully subscribe and get data. See the refresh and update messages in previous post.

Have you tried using this sample?

sabri demirel

Sorry for empty Project, I attached again.tr-websocket1.zip

I haven't tried you market_price_batch_view.js example yet. I will try it.

Gurpreet

@sabri demirel

Please comment out the line# 232 in TRWebSocketController.js:

// marketPrice.Key.Service = "IDN_RDF";// "IDN_RDF";

and try again with your original item: TRYTOM=D3

The sample is hardcoded to request data on IDN_RDF, and ignoring the service name argument passed in the call. I will request sample author to update the sample.

sabri demirel

Hi @Gurpreet

Are you sure about Service? In your example;

"Key": {
"Service": "IDN_SELECTFEED",
"Name": "TRYTOM=D3"
},

TRYTOM=D3 is name not Service, Our Service is IDN_RDF

I can replicate the issue by configuring ADS to use SSL protocol instead of RSSL protocol

*ads*routeList : hostssl
*ads*hostssl.route*serviceList : IDN_RDF
*ads*hostssl.route*port : rmds_ssl_sink
*ads*hostssl.route*hostList : 192.168.27.48
*ads*hostssl.route*userName : DACS_CASCADE
*ads*hostssl.route*protocol : sslauto
*ads*hostssl.route*singleOpen : True
*ads*hostssl.route*compressionType : 1
*ads*hostssl.route*pingInterval : 2

The routeList uses hostssl route which connects to rmds_ssl_sink port with sslauto protocol.

You need to configure ADS to use RSSL protocol instead, as shown below.

*ads*routeList : hostrssl
...

*ads*hostrssl.route*serviceList :  ELEKTRON_DD
*ads*hostrssl.route*port : rmds_rssl_sink
*ads*hostrssl.route*hostList : 192.168.27.46
*ads*hostrssl.route*userName : DACS_CASCADE
*ads*hostrssl.route*protocol : rssl
*ads*hostrssl.route*singleOpen : True
*ads*hostrssl.route*allowSuspectData : True
*ads*hostrssl.route*disableDataConversion : True
*ads*hostrssl.route*compressionType : 1

The routeList of the above configurations uses hostrssl route which connect to rmds_rssl_sink port with rssl protocol.

Please change routeList to use rssl route protocol. If it doesn't solve the problem, please share the following information:

The version of ADS
The ADS configuration file

Jirapongse

A community member found a solution of this issue by changing the dataType of IDN_RDF from 2 to 6 in ads_pop.cnf.

*ads*IDN_RDF*dataType : 6

dataType 2 is a legacy standard Marketfeed Record format while 6 is RWF (Reuters Wire Format).

The data type of service for Web Socket API must be 6 (RWF).

Hi @Gurpreet,

@moragodkrit

We can get data via websocket now. The problem was our Reuters server configuration. It solved by Reuters Istanbul.

We have another problems now;

I have to get the initials values of a RIC. But Reuters server send to us only the updates after we send request. For example; If there isn't any update for 60 seconds , we can not get any response. How we can get the initial values?

Second problem is for TRYTOM=D3 Rıc. For this RIC the response is not valid, we cannot parse the json response.

This first response message that you received is an initial image:

an update will be of type

I do see that the JSON response for this instrument TRYTOM=D3 is not valid, and will raise it with product team.
