Gaps in the publishing sequence number when viewing RTI Recording Service's recorded database

When viewing recorded data in a database created by RTI Recording Service, if you see gaps in the column of publishing sequence number, it might not indicate that there were samples lost during recording. This can happen when a DataWriter explicitly calls unregister_instance() with the QoS policy, ...

On VxWorks, an RTP application can not discover a kernel application over shared memory

When running two applications on the same WindRiver VxWorks target, one in kernel mode and the other in RTP mode, the two applications will not discover each other when using out of box settings in RTI Connext. The reason this occurs has to do with how RTI Connext internally marks the individual ...

Resources are not cleaned up when write() is called from a spawned thread

If the logic of your application requires to spawn new threads, and in those threads you are calling a DDS API such as write() , you may notice a memory growth. To ensure that all the resources allocated in that thread are correctly released, remember to call unregister_thread() right before ...

For a large or complex topic data type, why can't generic DDS applications such as Admin Console, DDS Spy and Recording Service get the data type information?

For a complex topic data type that has many fields or long field names, Admin Console may not be able to show the topic’s data type, DDS Spy may not be able to print the samples’ contents, Recording Service may not be able to record the data, and Analyzer may show the warning “Failed to create ...

How to configure apps for backward compatibility 5.1.0 to 5.0.0

We have changed the default transport settings for RTI Connext DDS 5.1.0 to support better out-of-the-box throughput. This gives better performance, and in some cases reduces the time of the discovery process. However, this means that you must change your applications' transport settings in order ...
