Automatic DDS data to JSON for web integration service

Hello,

I am currently experimenting on usage of RTI web integration service between the publisher and subscriber that are C++ based.

I noticed that the data POST/GET is in either JSON/XML format.. What are the options available in the automatic data conversion/serialization to JSON/XML format?

The last option could be writing the converters for each and every type.

Thanks.

rtiddsping discovery w/o data

Hello--

I'm trying to establish DDS connectvity between two hosts, which are now directly connected with 10GB fiber to hopefully simplify the testing as previously there was a 10GB switch involved.

After following advice across several posts on this forum, I've brought the experiment all the way down to these two directly connected hosts and am using only the rtiddsping application with no special arguments or QoS settings, including verifying that the environment is clean and the process is not reading any QoS files.

Comparing DDS Entities

Hi,

I have been maintaining a structure (c-struct) in my application which constitutes of 

{

DDS::Entity

ReaderCallback

ReaderStatusCallback

...

}

DDS:Entity, as you know can be either a DataWriter or DataReader etc.. I maintain a list of these structures within my base application - probably for some legacy purposes which I dont want to dig in now. During filling the list, I plan to check for an existing DataWriter using the following logic:

Timeout on wait_for_acknowledgements

Hi,

I encountered a strange behaviour- atleast theoretically I felt it strange.

I have a topic which is configured with 'ASYNCHRONOUS_PUBLISH_MODE_QOS' and 'StrictReliable.LargeData'. Due to some application requirement I had to wait on acknowledgement for every write. So, effectively for every sample write I am calling "wait_for_acknowledgments" with a timeout of 2 secs. I am running a pub-sub case with multiple passes. Few times (observed it twice atleast) I see that the wait call returned with TIMEOUT, though the subscriber received the sample - the logs confirm that.

Acknowledgement from "all" subscribers

Hi,

I am dealing with pub-sub of large data, and obviously this follows with "ASYNCHRONOUS_PUBLISH_MODE_QOS" policy. Since I wanted late-joiners to access informartion, I also added durability QoS with TRANSIENT_LOCAL_DURABILITY_QOS kind.

Now, this is my question.

Can I be sure that the subscriber receives all the published ones? If not, is there a way (DDS-way) to know that the topic is consumed by all the subscribers - atleast communication went through and data reached the subscriber?

Inherited dds topic structs

Hi,

I am looking for inheritance kind of model with DDS topics. For example, I want the listener/receiver to listen to "one" topic (say, Shape) but the sender to send any of the inherited topics (say, square, rectangle etc..). Is it possible to achieve this in DDS first of all?

I have specific usecases for this. So trust me, when I say I need it.

Thanks in advance.

Uday
