Can anyone tell me the differences between head node and compute node used in datastage?

Really too much like an interview question to be simply answered by anyone here but since Ray has already handled an identical question in the past, I'll link to it:

Go find the Grid Enablement Toolkit Redbook. It will be helpfull.

In a nutshell:

Head Node = Job coordinator.
Compute Node = worker bee(s)

Don't crunch numbers on your head node.
Don't move data from your head node.

You only have one head node, but you can have a ton of compute nodes. Move work to compute nodes and free up more room on the IP Stack of the head node.

The head can contain lymph nodes. The computer cannot.
