Clear my doubt about the Communication Chanels and server nodes

[Former Member]

Hi,

I have some basic question on the Communication channels, server nodes and the messages to be processed,

Its very simply query as,

I want to know few things like,

1. What are these Server Nodes? where they come into play

2. How the communication channels choose these server nodes to process the messages?

3. And how the maximum concurrency play a vital role in this situation?

Thanks,

hi ,

1. J2EE Engine cluster consists of one or more Java dispatchers, several server processes, the

Central Services (Message Service and Enqueue Service), and the database.

if u have one server Node then if u processing the more messages at the same time then the load of

the server will increase .

so that we created more server nodes and run them in parallel then the load will reduce..

Ex:

Internet-Java DPServer processes----DB

this is single server node....

-Java DPServer processes----

Internet--

---

Java DPServer processes---- DB

-Java DPServer processes----

so the run time 3 message can able to processes parallel..

so the load will reduce...

2. Maximum Concurrency, specifies how many messages the adapter is to process in parallel in a cluster

node.
