Can we specify SO_REUSEADDR or SO_REUSEPORT options using QOS?

We are running into a problem when our application attempts to open a socket on a specific port for receiving UDP blocks when that port was already given to and is in use by RTI.  We only use the UDPv4 transport option, so when RTI/DDS Software launches it will request 3 ephemeral ports from the OS (VxWorks/RHEL) for DDS communications for the send sockets.  The default configuration that VxWorks uses for these ports is a pool between 49152 and 65535.   There is a small chance that these port numbers will collide with ones that should be reserved for our application, whi

Problems with loading xml file for QOS

I am new to RTI DDS and I am having issues with the xml file defined in the NDDS_QOS_PROFILES environment variable. I have defined this environment variable to point to my xml file. However when I run my application and try to do the following, my participaint doesn't get created.

(using c++11)

In my application, I have read in the environment variable and outputted this in my log to verify there were no issues with that.

I have also invalidated the <dds> tag in my xml file, but haven't seen any error message.

unable to find topic_qos and more from Qos_Profile in xml file

Hi currently i am trying out RTI Connext and i encounter a problem when i try to use an QoS file which was used for the ADLINK's Opensplice implementation. 

I added the qos_library is should, but it still can't find the sub elements past the qos_profile.

this is a snippet of my QoS.xml file.

 

<?xml version="1.0" encoding="UTF-8"?>
<dds
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="6.0.0">

<qos_library name="TestLibrary">
<qos_profile name="TestProfile" >

DataWriter public attribute transport_selection not appearing in rtiadminconsole?

Hello,

We are using RTI DDS v5.3.1 on RHEL 7.5 x64.

We are trying to troubleshoot a DataWriter.  We have the datawriter selected in rtiadminconsole, but the public attribute 'transport selection' does not appear.  We want to see what this value is set.

I expected all the public attributes of a DataWriter to show up.

Is this a bug or a feature?

regards,bernardo

Loading a QoS

I am trying to get my LabVIEW DDS application to use a custom QoS.  I have created the file "USER_QOS_PROFILES.xml" and (for now) put it next to the labview.exe executable (C:\Program Files (x86)\National Instruments\LabVIEW 2017).

Currently my QoS doesn't contain any data - just a reference to the LabVIEWLibrary::DefaultProfile to see if I could get that working.  Now, whenever I load one of my test reader files, I get a pop window (that looks like a console window) that says:

Hello,

I am relatively new to DDS and hope I get some help here. I have read up many threads and help topics regarding QOS and many examples are for Linux, as I am working on a Windows machine.

I am using this function:

How to change thread priority?

Hello everyone,

I am having some troubles with thread priorities.

I am running a pub/sub application on VxWorks and I notice that for each pub/sub that I run, 4 threads with priority 71 are created (named RTIOsapi).

I looked for it on the platform notes and I noticed that "71" is the THREAD_PRIORITY_ABOVE_NORMAL value for VxWorks.

I would like to change this value somewhere in the XML QoS file. I found out that there is a tag:

<thread>

     <priority>...</priority>

</thread>

Deadline > Lifespan

Is it correct that if the deadline period is chosen greater than the lifespan period then the on_requested_deadline_missed will never take effect?

Is participant mismatch an issue?

I have a number of 4 partipants running on the same domain ID and two of those talk exclsuively to one another and so does the other pair all on different topics. I have modified the participant on one pair to use a different UDPv4 message and buffer size but do not wish to do it on the other. Right now each pair seems to be sending a recieving messages however all the log files a reporting warnings that the transport into does not match and I am also seeing "Discovered remote reader using a non-addressable locator for a transport".
