Hello @alfredo.brito01,

Can you please have the customer try one of the Websocket samples. If they are still having issues, please provide the complete logs. The error message seems to indicate that it is an Authentication issue - i.e. DACS ID is incorrect. For a local RTDS, their administrator can provide them with a valid DACS ID, which should be passed into the user parameter.

Hi Gurpreet,

There was a problem in the way the request was send out from machine because the request was sent through proxy and because that never reach RTDS machine.

Now that connection is established, they are receiving an error related with what seems a license need, but I never seen this license in RTDS infrastructure.

Do they really need a license like that to retrieve real time data from RTDS infrastructure when using websocket connection?

"Request Rejected: Cannot request snapshot batch or dynamic view due to unavailable SNAP_AND_DYNAMIC_VIEW license."

Hi Gurpreet,

Do you have a sample of a streaming request that could be shared with customer?

Hi Gurpreet,

Apparently, samples are not so "plug&play"... customer is trying to use batch sample and now they got a new error:

SENT:

{

"ID": 2,

"Key": {

"Name": [

"TRI.N",

"IBM.N",

"T.N"

]

},

"View": [

"BID",

"ASK",

"BIDSIZE"

]

}

RECEIVED:

[

{

"ID": 2,

"Type": "Status",

"State": {

"Stream": "Closed",

"Data": "Suspect",

"Code": "NotFound",

"Text": "Request Rejected: Key on Batch ItemList Request did not contain service Id."

}

}

]

In sample apparently there is no service ID defined in Key parameter:

requestJsonString = "{\"ID\":2,\"Key\":{\"Name\":[\"TRI.N\",\"IBM.N\",\"T.N\"]},\"View\":[\"BID\",\"ASK\",\"BIDSIZE\"]}";

Which service ID is expected to have included in the request?

Thanks & Regards,

Alfredo

Hi @alfredo.brito01,

Its better to ask client to directly ask the question and engage with us. The samples are indeed plug and play - the user's RTMDS doesn't define a *ads*defaultJsonServiceId parameter in the ADS. So the user will have to explicitly specify which service they intend to request.

The request message should look like -

{
  "ID": 2,
  "Key": {
    "Name": ["TRI.N", "IBM.N", "T.N"],
    "Service": *****
  },
  "View": ["BID", "ASK", "BIDSIZE"]
}

I see that user is also requesting the view - and they don't have the license for it.

Hi Gurpreet,

They already have license FEATURE_34_SNAP_AND_DYNAMIC_VIEW activated in their RTDS-ADS system.

Regarding "Service", not clear if this is the name of real time service defined in RTDS (i.e. IDN_RDF) or something aleatory they can choose (a name or a number). Could you please clarify?

(I will ask them to start using Developers Portal Forum to raise their questions, but they are developers that are not aware about RTDS specifications and they need also some guidance when RTDS parameters are needed.)

Best Regards,

Alfredo
