currently I am working on a project using the Sybase ESP, which
is part of my bachelor thesis.
As I planned to write about clustering in ESP, I need to understand
the basic concept of managers and controllers.
As far as I understood:
- 1 Cluster consists of 1 or more ESP Servers
- 1 ESP Server consits of 1 or more Nodes
- Each Server needs exactly 1 Controller, and at least 1 Manager.
Is this assumption correct?
And in the next step, I couldnt really find an explanation, what tasks
a controller ( and the manager) have.
Could anybody roughly point me out the major tasks of a controller
and a manager? (or a document I can find an explanation in).
Thanks in advance,
and best regards
