rtirecord hangs when recording ping at 100 samples per second

I'm remotely controlling rtirecord using a java application. It works fine recording pings until I increase the sample rate to 100 samples per second. At different points in my application, the rtirecord process stops sending heart beat and stalls. Attached is the java code and rtirecord xml file I use.

Record/Replay seem to read default config when it shouldn't

To run rtirecord or rtireplay, I made a copy of the example RTI_RECORDING_SERVICE.xml or RTI_REPLAY_SERVICE.xml configuration files in the resource/xml install directory.


Then, I ran using the -cfgFile <> option, specifying my local copy of the config.

When running this way it consistently gives an XML error indicating that the "default" configuration (or any config name) for that matter has already been defined.

Use of name idl as a module doesn't work

This:

module idl
{
 enum A { a, b, c };
};
module other
{
 struct s
 {
 idl::A myA;
 };
};

  

when compiled using 

rtiddsgen file.idl

Maximum DataWriter on a Computer

We have 7 processes running on a single computer.  Each process creates 3 domain participants with domain id 0,1, and 2.  Our system has less than 80 DataReader/Writer combined.

The symptom is some DataReader/Writer from process number 6 or 7 (the process that was launch later) will not be discovered by rtiddsspy nor other processes.  There are no error message from RTI DDS, and DataReader/Writer pointers return from publisher->create_writer is non-null.  The application can still send data using those "problem" data writer and get a return ok.

Getting error "PRESWriterHistoryDriver_completeBeAsynchPub:!make_sample_reclaimable"

I'm working with RTI connext 5.0.0 and using an older quality of service file from a previous project running connext 4.5d. It doesn't seem to have any problems running with the QoS file, but I'm getting a bizarre error on write that I haven't seen before. It seems to only happen when a reader goes down, and it leads me to believe the writer on the same topic is getting stuck trying to write to it, which didn't happen in version 4.5d.

RTI Shapes Demo and RTPS2 protocol

Hello,

I have two instances of the RTI Shapes Demo running on one PC while capturing RTPS2 packets.  I am able to see the PIDs in the DATA(r), (p), and (w).  However when I manipulate the position of the shapes on the publisher instance I do not see any RTPS2 packets containing the change of the shape's location even though it is being mirrored on the subscriber instance.  Is the location of the shape published on RTPS2 as well or are they being communicated differently in the Shapes Demo?

Thank you.

v/r,

marlo

Recording DDS traffic without Recording Service

Has anyone attempted to record DDS traffic without using the recording service? We need to record and playback dds data, but we're unable to use the recording service because we're using VxWorks for our OS, and don't have access to a Windows or Linux machine during operation. I've browsed the forums and have deduced some potential options:

  1. Use Dyanmic Data API to subscribe to DDS data and serialize/deserialize to a file
