EMA Java failover

Hi,

I'm using ChannelSet to configure multiple TREPs hosts to make failover when one is down.

<ChannelSet value="Channel_1,Channel_2,Channel_3,Channel_4" />

I tested and work fine, the application initially connect to Channel_1 and when down connecting to Channel_2.
My question is when connected to Channel_4, if it is down, the Api will try to connect back to Channel_1 or not?

Thanks
Stephane

Hello @Stephane Rossi

I have tested 3 channels (as I currently have only 3 ADS in my environment - they are all ADS 3.x versions) with the following configuration:

<ChannelSet value="Channel_1, Channel_2, Channel_3"/>

When Channel_3 is down, the application connects back to Channel_1 successfully.

Please note that it is recommended to use the same version of the ADS server and each server has the same services for the API failover feature.

Hi @Stephane Rossi

My understanding is that it should rotate back round to Channel_1.

I will seek confirmation and get back to you.
