Integration

Hi,

At the moment it takes my first cluster node approximately 30 seconds to start and setting the packet-delivery timeout smaller than this means the system cannot start. I'm trying to reduce the packet-delivery setting to improve responsiveness during failover caused by hardware failures. I think 15-20 seconds would be ideal, allowing for GC pauses.

Subsequent nodes can start in a couple of seconds.

Is this a reasonable time to expect the first Coherence node in a cluster to start up? What kind of values is everyone else working with?

Thanks & Regards,
Martin

The error when packet-delivery is less than 30 seconds:
