What is multicast address in WebLogic?
A multicast address is an IP address in the range from 224.0. 0.0 to 239.255. 255.255. The default multicast value used by WebLogic Server is 239.192.
What is a Unicast cluster?
Unicast: A unicast cluster requires that you configure the IP addresses of the nodes in the cluster. If a server has multiple interfaces, use the internal IP address that allows the node to communicate directly with other nodes. Clustering across different subnets is not supported.
Which protocol is being used by WebLogic for internal communication?
The WebLogic Server unicast protocol uses standard TCP/IP sockets to send messages between cluster members.
What is Multicast and Unicast?
A Unicast transmission/stream sends IP packets to a single recipient on a network. A Multicast transmission sends IP packets to a group of hosts on a network.
What is WebLogic T3 protocol?
T3 is the protocol used to transport information between WebLogic servers and other types of Java programs. WebLogic keeps track of every Java virtual machine connected to the application. To carry traffic to the Java virtual machine, WebLogic creates a single T3 connection.
What is cluster communication?
When you use both the IP-based network communications and the storage interface communications, all nodes in the cluster can always communicate with any other nodes in the cluster configuration. Having clusters in this configuration eliminates “split brain” incidents.
What is the difference between a Multicast and Unicast cluster?
Unicast uses TCP communications and this usually requires no additional network configuration. Multicast uses UDP communication and Multicast addresses and this may require some network configuration and an additional effort in selecting the address to be used.
What is clustering in mule 4?
Clustering is a group of servers or mule runtime which acts as a single unit. In simple terms, virtual servers composed of multiple nodes and they communicate and share information through a distributed shared memory grid.
What is T3 protocol in WebLogic?
What mechanism do cluster members use to communicate consistent information about cluster membership?
Periodic signals sent out every 5 seconds by cluster members to communicate with each other and maintain consistent information about cluster membership.
