Hello @yacine.aitsaid,

This forum is dedicated to the discussions and general questions on Open DACS API usage.

Open DACS API is often configured in Multi Connect mode, to connect to multiple dacs_snkd instances, each interacting with a dacs_srvr. This is how resiliency can be achieved via Open DACS API. Please see examples DacsMultiConnect that are included with OpenDACS SDKs.

Configuring dacs_snkd, is not strictly within the expertise of the members and moderators of this forum, as both are, in their majority, developers. Rather, the best guidance on installing and configuring dacs_snkd can be found with DACS admins, either from your local market data organization, or via Refinitiv Helpdesk Online -> Product -> DACS

To my limited experience, it is one; a dacs_snkd cohabitates either with ADS server (remote to OpenDACS) or OpenDACS client (local) and connects to a single dacs_srvr. A DACS installation often includes more then one dacs_srvr.
