Persistence Service

Hi,

I use rti v6.0.0

Im using persistence service. I set the "datawriter durability qos" in my project in "persistent". And i set the xml for that saves datas in file system.

When i unregister an instance that registered before, i expect that the instance won't publish by persistence service even when datawriter that calls dispose destructed and removed from domain. But unexpectedly when i destruct datawriter that caled unregister_instance persistence service publishes that instance from its history.

I am trying to run the rti persistence service through the command line but I am getting an OBDC error claiming a table doesn't exist. The error is below and I have attached my persistence config file incase that is at fault.

I have also tried starting the persistence service through the rti launcher but encounter the same error

Hello everyone,

We are building a new adaptation application and are considering using DDS persistence service to store adaptation rather than copy xml files to each node on the network.

One concern that we have is that we expect this data to be modified between software releases (table data may be added or removed). Our application is a 24/7 application so shutting down everything is not really an option.

Hi there

If I run a publisher and subscriber pair, I get an average of 150k samples per second. Once I enable the persistence service (writing to disk) in addition to the regular subscriber, the sample rate falls to about 2k samples per second.

I surely must have a configuration problem?!

I'm using the default configuration file in rti_connext_dds-6.0.0/resource/xml/RTI_PERSISTENCE_SERVICE.xml

Any pointers are greatly appreciated!

Thanks,

Ben

Hello everybody,

I'd like to know if it is possible to check if an instance of Persistence Service is running in order to be sure that my samples are stored correctly in non-volatile memory.

I'd prefere not to use Remote Administration of the service.

Thank you in advance and best regards

Hi

I cannot start rti persistence service in my computer. The error is as follows:

PERSISTENCEDatabaseManager_initialize:ODBC error: connection string too long
PERSISTENCEDatabaseManager_new:!init database manager
PERSISTENCEService_initialize:!init database manager
PERSISTENCEService_new:!init persistence service
main:!create persistence service

What should I do? I don't want to remove my database files. Thanks in advance for your helps.

Hi everybody,

We are working on an application that is meant to load its configuration from the DDS persistence service. However, we are struggling to load data into the persistence service reliably.
