TREP API: [CIRCULAR REFERENCE:com.reuters.rfa.common.DeactivatedException]

Hello,

Am currently having [CIRCULARREFERENCE:com.reuters.rfa.common.DeactivatedException] and just wondering if anybody could tell me what is causing and what do I have to do when I encounter this exception.

Regards,

josa

@josa

By successfully consuming the same instruments from StarterConsumer example you have confirmed that your user is permissioned for all the instruments, this is good.

1. StarterConsumer is requesting instruments one by one. The custom one is using Batch View request, to request them in a single request, with a subset of fields. Test your requirement with BatchViewConsumer example from SDK. See if you can confirm Batch View request capability.

2. I can see from the trace that your request is non-streaming. Are you are not keeping dispatch running when your receive your responses?

3. Print "inCleanup" as the first line of your cleanup method and run, or put breakpoint there and debug. You should learn where it's being called from and when.

(From RFA trace I can only tell what happens, not how it's caused by the code)

Thank you @josa,

You are on the latest RFA Java.

This is the application log, not RFA trace?

Can you enable low level trace log in your application and upload the resultant trace?

This can be done by setting the ipcTraceFlags to 7 in your connection parameters as well as setting mountTrace=true

This should result in a log file with a default name of RFA_RSSL*.log or RFA_SSL*.log depending on your connection type.

For further details on the above and related parameters please refer to the RFAJ_ConfigLoggingGuide.pdf which comes with the RFAJ API package.

If the file is large, please zip before uploading.

Will try to learn more.

If you are seeing the above exception on uninitialization/shutdowm, review your unitialization code for consistency, if it is threaded, make sure that unitialization is consistent for all threads.

@zoya.farberov, the exception is occuring in the code below

public void run() {
long startTime = System.currentTimeMillis();
while ((System.currentTimeMillis() - startTime) < 600000) {
try {
eventQueue.dispatch(1000);
} catch (DispatchException | RuntimeException de) {
throw new EventDispatcherException(de);
}
}
}

How will increasing or decreasing 1000 in the eventQueue dispatch method params affect the code above? Am sure this is what is causing the exception.

Regards,

josa

@josa,

Having taken a look at the trace, it breaks off right after login close request.

I would check first, if you are not perhaps, dispaching on the queue, after deactivating it? This should lead to the exact exception you are seeing, even if the queue is empty by now.

Another possible approach, has this application started with one of our examples? What was modified/added, likely, at uninitialization stage? That difference could give you the clue you are looking for?

Dispatch loop is what keeps the application running, doing even processing

int dispatch(long waitMillisecs)
      throws DeactivatedException,
             DispatchQueueInGroupExceptionDispatch the next event. Wait for waitMillisecs milliseconds if no event exists.

Therefore, by making this interval too small, you will do a lot of costly unnecessary checking on the dispatch thread, by making it too long, hold up the thread, unnecessarily.

However, if modifying the dispatch timeout appears ot help, you are likely covering up the incorrect uninitialization, rather then fixing it, potentially, the timing issue just becomes less prominent.

---

Would like to mention, that if this is a new app, I would encourage to look at EMA Java to implement. If there is flexibility on your side to use EMA Java to implement your requirements, all these semantics and potential issues will be handled for you by the API, seemlessly, on the background, making the necessary consumer code times smaller, and much simpler. The primary reason EMA, part of the next generation of our APIs, was introduced, so that application developer could spend minimal effort on subscription side, and be able to concentrate on the business side of the requirement.

Hi @josa,

I have taken a look at the code you have shared. I do not see anything wrong. I do not see deactivate or unregister called. I know it's in diiferent part of your app.

My line of thought is that if the order of uninitialization, at some point, is not observed, it may result in teh exception you are seeing. Roughly, it is as demonstrated in our consumer examples:

if ( _connIntSpecHandle != null )
        _ommConsumer.unregisterClient(_connIntSpecHandle);


        // unregister all items
        if (_itemManager != null)
            _itemManager.closeRequest();


        // unregister login
        // Allow conditional login unregister.
        // loginCleanup flag is set to false if cleanup is called after login
        // failure.
        if (_loginClient != null && doLoginCleanup)
            _loginClient.closeRequest();


        if (_ommConsumer != null)
            _ommConsumer.destroy();


        _eventQueue.deactivate();
        _session.release();
        Context.uninitialize();

If you are running this from multiple threads, two approaches to find the issue, to me, are:

  • Put breakpoints before the key steps indicated above->debug->step-by-step try to see if you dispatch after deactivation, or any other unexpected behavior is happening
  • Put print statements before key points and try to detect "out-of-ordering" this way

If you need more help, and if you/your organization is a TRDC member, open a TRDC ticket, and have our experts look at the complete code.

Hello @josa,

I would put a logging statement as the very first line of cleanup method, and carefully examine the output, to make sure your application only calls it once.

Thanks @zoya.farberov. The problem we are having is this. This client application runs as expected with our Reuters test account. But when we use it on a third party client account (different IP and different service name, but same RICs) it returns nothing. Both our test accounr and the clients test account is permissioned for the requested RICS. Any thought what is going on.

NOTE that we can telnet to the clients box.

josa

In the trace, that I find attached, MarketPrice for CLH9 is returned to the consumer:

-> login request
<- login accpet
-> directory request
<- directory IFC, ELEKTRON_DD
-> request MarketPrice CLH9, non-streaming
<- refresh MarketPrice CLH9 ***
-> Close request MarketPrice
-> Close request Login   

But it seems that you are saying that nothing is returned?

Does the trace attached before correspond to the run when you get "DeactivatedException"?

--------

Deactivated exception, happens when the application tries to access a deactivated queue. For example, cleanup was run already ( from one request) and then you try to run cleanup again (from another request, usually on a different thread). This is the reasoning for my suggestions above on how to approach debugging.

--------

Yes, it is possible that a consumer will run differently on connecting to a different system. If the timing is different, an issue in the consumer code can be masked on one and exhibit prominently on the other.

--------

If you get nothing with third party account(?) and not the refresh that I see in trace, I would test third party account with a standard client. For example, StarterConsumer that came with RFA Java SDK. Make sure you get a response for the RIC you request. Then move on to the custom consumer testing.

I will take a look.

To clarify what I am reviewing:

Is this trace with "third party account" + Deactivated exception?

Have a you had a chance to test "third party account" + StarterConsumer from SDK?

Thanks

Thanks, this should help

To clarify:

When you run the client you have developer with reuters test account, you get back the data and see no issues?

When you run the client you have developed with third party client account you get no data and get Deactivated exception?

In your last attached trace:

MarketPrice Batch View request for 6 items:

"CLH9" "HOU8" "IBM.N" "JPY=" "MSFT.OQ" "TRI.N"

view: "BID" and "ASK"

I see refresh responses for CLH9 and HOU8, and no refresh responses for the rest. The there is close requests for all 6 MP streams and login close.

Are you seeing and paring these refresh responses?

Does Deactivation exception happen after that?

Please confirm the client account you use to consume is permissioned for the rest of the instruments and should be receiving them, do you register for and parse "not entitled" status?
