Controlling use of network interfaces (Dev Portal)
Typically our production machines have 4 network interfaces and we need to control which interface is used for SLEE cluster traffic. Is this controlled by the machines' multicast configuration or is there a different mechanism? Is it also tied in with key generation? This issue came to light ...

Do applications receive any notifications of activity failover when a node fails? (Dev Portal)
node fails, does the application running on remaining cluster members receive any notification that a switchover is taking place so that it may perform any preparation work (if needed)? When a node fails, Rhino reallocates its activities to surviving nodes ...

Error deserializing from ACI because objects are too large (Dev Portal)
Our application is running OK on a single node but when we attempt to demonstrate that the SLEE is replicating ACIs across a 2 or more node cluster we get a EOFException. So why does the exception not occur on a 1node cluster too, then? This will only ...

How can I disable mutlicast traffic in Rhino? (Dev Portal)
Author bsd For testing purposes only, can I disable the multicast messages sent by Rhino on a deployment of a single node? Multicast traffic should not have any relevant impact on the network (even with one node deployments) There is no way to deactivate multicast ...

How can I ensure that CMP fields in one node are replicated to other nodes in the cluster? (Dev Portal)
How can I ensure that CMP fields in one Rhino SLEE node are replicated to other nodes in the cluster? A service in Rhino can be configured as replicated. By configuring the service as replicated, Rhino will replicate all SBB entities and their state (CMP fields ...

Issues with some watchdog errors (Dev Portal)
We had a SLEE restart in one of our clustered labs. In looking at the logs on the node that restarted (node102 for the purposes of the attached log files), I do notice a log indicating that the time drift is greater than 2000 ms but before that, I ...

Multicast traffic load of a Rhino cluster (Dev Portal)
What is the load in the multicast messages between the Rhino nodes. I suppose this size depends on what Rhino is doing (replicating a profile,...) but, what's the maximum and tokens' size? Tokens are on the order of 50 bytes. Maximum UDP datagram size is configurable and defaults ...
