Regarding thingworx platform scalability

[esirohi]

How can we connect two or more thingworx instances to SINGLE Postgresql DB instance?

Also, what all options are available from scalability point of view and what is the limit of connected devices per thingworx instance?

I am not able to access the ThingWorx High Availability (HA) link. Can you share that document with me?

Thanks.

Out of curiosity, are you trying to connect two TWX instances to the same PostgreSQL *database* or the same postgresql server? You can have multiple instance of TWX on the same postgresql database server by simply creating multiple databases and configuring TWX appropriately, but you cant share a single database across instances of TWX -- otherwise the entities would overlap. You can offload data storage from a TWX instance to a remote data storage server, however -- see: Federation for details.

Hi Ankit Gupta​ & James McCuen​,

Need one clarification on Example Architecture provided in 'ThingWorx 7 High Availability Administrator’s Guide'.

If only one TWX instance will become leader and fully connects to the database. what is the actual purpose of other two TWX instances when not fully connect to database?

How are we attaining Load balancing here?
