Thanks, Hugh.

We will almost certainly use that now that we have replication.

Hi Daniel,

 

All the Virtuoso Data Access Clients for JDBC, ODBC, OLEDB, ADO.Net 
<http://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

That is:

*Does the open source VirtuosoDataSource have any fault tolerance 
features built-in to work with Virtuoso commercial’s replication and clustering 
features?

*Has anyone out there experimented with something like HA-JDBC for 
Virtuoso?

[Virtuoso-users] VirtuosoDataSource fault-tolerance

wondering whether anyone out there has experience about the fault tolerance of 
VirtuosoDataSource.

That is:
