I have the "EMA Consumer - Request & Decode Machine Readable News" as the basis for an MRN consumer client up and running.
I need to be able to cope with connection issues and status messages. I cannot find that information in the "ELEKTRON MESSAGE API DEVELOPERS GUIDE".
Can anybody give me an example of how to deal with connection issues and OnStatusMsg issues?
Thanks
Dave
Please refer to the following post on details regards Status Msgs
Handling Rssl states in ETA API
Although it talks about ETA - similar principals apply to EMA. As mentioned by Brian Sandri, take a look at the ETA developer guide - Appendix A 'Item and Group Decision table'
EMA will try and recover connections and items for you when possible. Use ChannelSets as opposed to a single Channel - to allow EMA to attempt failover to another server if the connection to one fails - Multiple hostnames
@Umer Nalla
In Appendix A there is a column STATUS TYPE. This has a value of Item or Group. How should this be used for MRN via EMA?
Thanks

From an EMA Consumer perspective you would only be interested in Items.
Groups are used by Provider applications to communicate changes to the state/status for groups of instruments more efficiently.
