Hi @johan.lundquist

Can you please confirm a few things:

• are you using one of our examples to start with? If so which one?
• has your market data team defined a NIP service on their ADH server to receive your incoming NIP connection request
• have you configured the EMAConfig.xml to define your NIP service details and connectivity details (and is the XML file in the working directory for the example)

I just tried running the simplest example ex100_MP_Streaming - using the default EMAConfig.xml file and without configuring my ADH details etc and I see similar errors/warnings as you do.
You will note the default DefaultNiProvider config of Provider_1 refers to Channel_7 for the server config parameters - which defaults to localhost. So my immediate suspicion would be that whilst the config file is in the correct location, it has not been modified to define your NIP service and/or connectivity details.

If you have not discussed your NIP requirements with your MarketData team please do.

Perfect thanks, I thought the config file was the one in the same directory as the tutorial example but you where right so now that's fixed and I get an expected output:

Waiting for 5 seconds...

Provider is connected. OmmState:Open / Ok / None / 'Login accepted by host.'

Refreshing JOHAN_NIP_ITEM

Waiting for 60 seconds...

Disconnecting...

Exiting the application

We have issues configuring the ADH server however so I have not been able to complete the test fully yet.

Kind regards,

Johan

Hi @johan.lundquist

I am sure you are aware of this but I just want to double-check..

As well as the file directory on your PC where the config is located, the Directory entries in the EMAconfig file are also relevant to this scenario.

Whilst the following article is concerned with SymbolList publication, you may find sections of it useful.
Publishing Symbol List using EMA Non-Interactive Provider

Also under the following Tutorials page Refinitiv Realtime SDK Tutorials

under the EMA NI Providers Tutorials, there is a section labelled - TREP Configuration for NI Providers which you may also find useful.

The provider seems to run but with strange errors like below:

Nov 06, 2020 3:38:47 PM com.thomsonreuters.ema.access.ConfigErrorTracker log

And the consumer can't pick it up due to "Service not available"?

StatusMsg

Hi @johan.lundquist

Looking at the EMA Java source code in Java\Ema\Core\src\main\java\com\thomsonreuters\ema\access\DirectoryServiceStore.java

if( serviceNameSet.contains(serviceName))   
{     config.errorTracker().append("service[").append(serviceName)                         .append("] is already specified by another service. Will drop this service.").create(Severity.ERROR);     
    continue;   
}

This would suggest that you are specifying the same service twice in the Directory config perhaps?

Please feel free to attach your EmaConfig.xml as a txt file if you wish for someone here to take a look.

You may also be able to Contact Premium Support so that this can be investigated offline in more detail.

Thank you @umer.nalla I think I got that error message resolved by remove it from the below:

<Service> <Name value="CURVEPUB"/>

But still my consumer doesn't pick up anything with same message state="Open / Suspect / None / 'Service not available'".

In .txt format due to some upload format issue:

NiProvider-->

Main-->

I tried the link you enclosed for offline support, which indeed sounds best, but I couldn't find any contact info for it from that link?

Thanks,

Johan

Remaining files due to upload restriction:

EmaConfig-->

Consumer-->

Hi @johan.lundquist

I will take a look at your uploads, and will also check with your account team if you are entitled to Premium Support.

Just a quick initial question, I assume the ADH + ADS are both running in the host xxxxxxx?

With regards to premium support, I assume you do not see the Contact button as shown below?

In the meantime, I recommend you ask your MarketData team to confirm if they can see a service status/stats for your CURVEPUB service in the ADH Monitor tool and ADS Monitor tool. They can then check if the status changes as and when you start/stop your NIPROVIDER example.

I would also recommend you running up one of our simpler NIProvider examples such as ex100_MP_Streaming / example100__MarketPrice__Streaming with minor changes for servicename etc, with your config file and see if it yields different results in terms of the ADH monitor and simple consumer. This will help eliminate the possibility of a coding error in your code.

If your MarketData team are not familiar with the ADH / ADS Monitor tools then they can raise a ticket for the Refinitiv Real-Time Advanced Distribution Hub product via My.Refinitiv and get some advice from an ADH / ADS specialist.

Thank you @umer.nalla, no I don't get that Contact support button unfortunately but I'll ask our KAM for that.

On TREP I have this:

And now I tested to use 365 as server id in my EmaConfig.xml, but still can't see any service up and running on Service Statistics on AHD monitor.

The NIP runs as below:

Waiting for 5 seconds...

Provider is connected. OmmState:Open / Ok / None / 'Login accepted by host '

Refreshing JOHAN_NIP_ITEM

Waiting for 1 seconds...

Updating JOHAN_NIP_ITEM

Waiting for 1 seconds...

But again can't see it on ADH Monitor, and whey trying to run a consumer I just get:

StatusMsg

streamId="5"

domain="MarketPrice Domain"

state="Open / Suspect / None / 'Service not available'"

name="JOHAN_NIP_ITEM"

serviceName="CURVEPUB"

StatusMsgEnd

Please note when we run the Refinitiv provider binary tool on TREP I can successfully consume the data from the one and same consumer I'm trying to consumer my own NIP app with.

Thanks,

Johan

Hi @johan.lundquist

Thanks for the detailed reply. Were you able to try one of the standard NIProvider examples as suggested earlier? Did this give the same result?

If the service is not appearing at all in the ADH monitor then that is concerning - since your app does report a successful login. Your MarketData team should raise a My.Refinitiv ticket so they can work with TREP support to ensure the rest of the ADH config is correct.

If the service is not showing in the ADH mon, then your consumer will not be able to connect - as the service is not available.

If the service does appear but is not showing as UP / Accepting Requests status - your MarketData team should check if there are any entries in the ADH log file which could provide further clues as to why this is not working.

I have checked and you are not a named Premium support user for your organisation, so I am checking if there are any other named members and if not, then I will see if there is another way of getting some offline API support so that this can be investigated in more detail.

Thank you @umer.nalla, I am in contact with our Custom Success Manager Mr. Hartmann and he will try fix the "premium support" issue so you don't need to waste your time on that.

"Were you able to try one of the standard NIProvider examples as suggested earlier? Did this give the same result?" - I am only running examples from your Tutorial.

And yes I agree the issue to be the service no showing up even as DOWN on ADH monitoring, I'm troubleshooting this as the moment.

I'll revert back to you once the service is appearing on TREP server.

Thanks for now,

Johan

@umer.nalla, short update my provider is actually successfully publishing as I could see in the ADH logs:

[Mon Nov 09 10:53:06.293689 2020] RSSL Message Of Length 47 Received on Socket 508
<!-- rwfMajorVer="14" rwfMinorVer="1" -->
<updateMsg domainType="RSSL_DMT_MARKET_PRICE" streamId="-1" containerType="RSSL_DT_FIELD_LIST" flags="0x8 (RSSL_UPMF_HAS_MSG_KEY)" updateType="0 (RDM_UPD_EVENT_TYPE_UNSPECIFIED)" dataSize="15">

<fieldEntry fieldId="22" data="0C38 C3"/>
<fieldEntry fieldId="25" data="0C3E 0A"/>
</fieldList>
</dataBody>
</updateMsg>

Now I'm troubleshooting why this service isn't available to see from a consumer perspective, somehow a progress still.

Hi @johan.lundquist

I note in the above output that the serviceID is 512.

Also, I just spotted in your earlier reply you mentioned serverID which is not the same as serviceID

ServerID is the unique value for each server instance, whereas serviceID is the unique value for each service/source available on those servers.

You should be looking for something like the following in your rmds.cnf

*NIPROV*serviceId : 260

Hi @umer.nalla, sorry I must have mismatched it in typo but yes I'm using serviceId 512 in my EmaConfig.xml:

<ServiceId value="512"/>

Matching the TREP's:

*CURVEPUB*serviceId : 512

It seems I am getting my Premium account now internally, however I think the issue is nailed down to this config on the TREP side:

Based on directions from Refinitiv documentation:

tconfig publisher_server -n <node name> -i "" -s <service name>

Is this .1 expected? -->

Thanks,

Johan

Hi @umer.nalla, finally I got it resolved by add instanceId with full string of server and id as:

provider = EmaFactory.createOmmProvider(config.username("").instanceId(""));

Do you know how I can set instanceId in the EmaConfig.xml instead of directly in the code as a last question?

Thanks,

Johan

Hi @johan.lundquist

Apologies for not replying sooner - I must have missed that reply notification email on the 12th.

The instanceId() cannot be set via the EMAConfig.xml at present - it is one of the few parameters that have to be set programmatically (you can refer to the EMAJ_ConfigGuide.pdf for details)

Can you confirm if you are running multiple instances of NIProvider application?

With regards server name - I removed the one reference I could find. If I have missed any others please let me know.

Perfect thank you @umer.nalla.

Yes I've managed to run multiple agents using different instance id's and it works fine.

Kind regards,

Johan
