The connection between my application and the Reuters Centers died again, I can't receive quotaio...

...n now. And the application can't reconnect itself.

Hi @Pimchaya.Wongrukun,

The connection died again, I have the log by using:

<Consumer>
  <Name value="Consumer_1"/>
  ...
  <XmlTraceToStdout value="1"/>
</Consumer>

Can you tell me your email, so that we can talk about this problem better.

Hi @Pimchaya.Wongrukun, I can't open the link.. reply here then. I found after received below data, there is no quotation data received anymore.But normal message still comes.

Can I have all results from the console output via a file attachment?

Normally, Market Price Status Message conveys state change information associated with an item stream, not the connection status.

In fact, if a connection problem does occur, EMA should rather logs the similar result below (e.g. ChannelDown) to console.

See ema-channel-down-message-log.txt for more message details.

Hi @Nipat Kunvutipongsak， I have uploaded the part of log, because it's too big. So I cut out some important logs for you.logdetail-question.zip

Hello @Raj.Huang,

I've checked the log file, and I can assure you that the connection's down on 15:44:41.772 (see below).

Received ChannelDownReconnecting event on channel Channel

This was generated from Reactor (underlying layer to indicate that this channel down event can be recoverable).

The connection was actually recovered on 15:44:42.789 as conveyed by the following text message:

Received ChannelUp event on channel Channel

Anyway, a streamId and item name conflict to each other. Considering the STATUS message type, we suspected that it should be a multi-threaded application, am I correct?

Hi @Nipat Kunvutipongsak,

I do use series100.example to test it, except that I add some logs. You can test it by yourself with @Nipat Kunvutipongsak, he told me how to send NO_DATA message.

Nipat Kunvutipongsak

@Raj.Huang, it's me who provided you how to send NO_DATA message in the other thread.

As you can see, the first message in the snippet is NO_DATA, and the com.thomsonreuters.ema.examples.training.consumer.series100.example100__MarketPrice__Streaming consumer application can continue receiving further updates. Please check the log file here: emaj-continues-get-data-regardless-no-data-message.txt

What's the version of EMA Java used (displayed in the log from both of Consumer and IProvider example -- you can check yours similar to the screenshot below)?
Can I have the log files from both of series100.example (Consumer and IProvider)?

Raj.Huang

Hi @Nipat Kunvutipongsak,

As I said before, it do receive incoming messages as your capture shown, but the onUpdateMsg() method at Consumer.java won't be called, so we can't decode data then. You can print a log after the method being called like below, so that you can check if the method being called or not.

Nipat Kunvutipongsak

@Raj.Huang I got your point; onUpdateMsg() isn't called after the status message.

I'll cross check this behavior with the other APIs and will get back to you.

Nipat Kunvutipongsak

@Raj.Huang

I've submitted a new issue to the development team on your behalf already (https://github.com/thomsonreuters/Elektron-SDK/issues/37).

So, you can communicate and follow up with the development team directly.

In the future, if you suspect there is an EMA bug/non-support feature or improper implementation/configuration in application level via GitHub at https://github.com/thomsonreuters/Elektron-SDK/issues, click "New issue" button, and put detailed information, then submit it to the Developer team.

Raj.Huang

@Nipat Kunvutipongsak，

Thank you, so this problem is a bug of EMAJ? And I still want to know why the Reuters server send the NO_DATA STATUS message out.
