dispatching read and write operations on a cluster

Hi, I have a question regarding read and write operations on a cluster:

when I create a pool specifying a list of IP addresses and an access profile (.pea file) I get back an FPPool

object I then use in operations (create, read, write) on FPClip objects.

The documentation now states "All clusters in the pool are eligible for read operations. Write and

delete operations must occur on the primary cluster. "

As I understand it the first IP Address in the list of addresses is the primary one, all other are

secondary.

How can I control from the SDK where write operations go; I specify IP addresses only when

creating a FPPool object and after this point I only use this object but not IP addresses any more?

A second question in this regard is how I can do load-balancing on centera: do I have to

create a number of FPPools and then do load-balancing upon the pools or is the FPPool

object able to process multiple requests at one time and does load-balacing internally?

Many thanks in advance,

  Chris
