titleTerracotta deprecated DSO (Distributed Shared Objects)

Unfortunately Terracotta deprecated the technology that Servoy used to provide Servoy clustering (DSO). So clustering is only possible with older versions of Terracotta that still support DSO and only with Java 1.6 (not higher). That means that Servoy 8 (compiled for Java 1.7) will not work at all with Terracotta clustering. There is a case in the support system for switching to other clustering tech. Servoy 7.x should still work with Java 1.6 and now deprecated Terracotta DSO.

Until this gets addressed: if your solution can be split into multiple completely independent servers (each user being served by the same Servoy Server all the time) you can try doing that - so keeping multiple separate independent Servoy Servers. Each server in this case has it's own independent subset of data. But this means you have to have subsets of users that don't need to interact with data stored on another server (so no data broadcasting/locking/... needs - no real clustering needs).

This chapter describes the set up of a cluster in Cluster installation and running the cluster in Operating the cluster.Installation..

A Servoy Cluster is best set up in combination with a Load Balancer. Adding a Load Balancer and a HTTP Server in front of the Servoy Cluster will provide the following benefits:
