I've a cluster with 12 nodes on weblogic 10.3.3 /linux which communicates in unicast.
In cluster > monitoring i can see that each node has the status drop out frequency : frequently
I've check configuration and everynode is in unicast mode (each config.xml). There is no problem of GC : less than 1% time spent in gc for each node.
Could you help me to investigate on this status ?
Many times when I deploy new applications (osb deployement) some nodes are not uptodate and I think it comes from this previous issue.
Thanks in advance.
Using Unicast is really good but when there is good amount of the node in cluster then it better to use Multicast instead of Unicast.
I recommend to use Mulitcast and enable tunneling on every managed server to see some good performance.
