RFA OMM States detailed description.

Hi,

Is there a detailed description of the meaning for the different Omm State's? What I need is all different combinations and what they represent.

EmaFactory.createStatusMsg()    .state(        OmmState.StreamState.OPEN,      // Stream state        OmmState.DataState.SUSPECT,     // Data state         OmmState.StatusCode.ERROR,      // Data status            "some issue")

I have so far only found examples of usage but not detailed description of all available scenarios in emaj_dev_guide_3.6.0.L1.pdf.

Kind regards,

Johan

Hello @johan.lundquist

You can find the full description of the RTSDK State on section 11.2.7 State of the Transport API J Developers Guide (also available as ETAJ_DevGuide.pdf document in the <RTSDK-Java package>\Java\Eta\Docs folder).

The ETA API is the transport API of the EMA, so the ETA's State object is the same as EMA's OMMState.

Another section on the ETA J Developer Guide that may help you is Appendix A Item and Group State Decision Table.

Additionally, on the EMA folder there is the OMMState document on the EMA Java reference manual document (RTSDK-Java pckage\Java\Ema\Docs\refman\emajava\index.html) as follows:

Hi @wasin.w V3

for Streamstates.OPEN and Datastates.SUSPECT, will it cause data loss before recover ?

Thanks

Yes, when the API receives Streamstates.OPEN and Datastates.SUSPECT status from the backend, it means a connection remains open, but the server cannot send data to the API.
