Hi Daniel, All the Virtuoso Data Access Clients for JDBC, ODBC, OLEDB, ADO.Net, Sesame, Jena etc support round robin connections for automatic fail-over and load balancing ie HA as detailed at:
http://docs.openlinksw.com/virtuoso/dataccessclientsconfailandbalance/
As this is in the client it can be used with Virtuoso server instances of any
form ie open source , commercial, scale-out cluster etc. provided the nodes are
known/considered to be in sync and hence can service user requests …
Best Regards
Hugh Williams
